Guys, Salvation is Simple HalleluYAH translates “Praise ye YaH” YaH is The Heavenly Father YaH arrives via the TENT OF MEETING YaH was Who they Crucified for our sins YaH was Crucified on an Almond TREE Ancient Semitic of Moshe (Moses) Isa Scroll (The Original Isaiah) Isaiah 42:8 "I am YaH; that is my Name! I will not yield my glory to another or my praise to idols.” Isaiah 43:11 “I am YAH, and there is no other Savior but Me.” Isaiah 45:5 “I am YaH, and there is none else.”
I saw that too. TH-cam is full of "expert" woodworkers who do the most irresponsible stuff on table saws. There's one well known guy, who I like his channel, but he routinely will guide pieces through where his fingers are about an inch away from the blade...
His biggest mistake is that he has the blade set way too high. Second is baggie cuffs on his shirt. Mainly, his blade is too high. He should use a stick to push the piece away from the blade before he puts his hand in there. But, asking for trouble with that blade height.
Its well and good that its compliant with UNI EN847, i run a dado stack in Ireland and had to import it from the US. However, good luck finding a table saw with an extended arbour in the EU, my saw is 36 years old (I played in the box it came in). On another note, my saw has a wobble blade, you'll never know sphincter pucker until you spin up one of those badboys
That was my thought... All the EU guys I know couldn't run a dado stack even if they wanted to, either because a) their arbor isn't long enough to accept it, or b) even if it is, the riving knife isn't adjustable/removable. I guess the assumption has been dado = no-no for long enough that most equipment matches that standard.
The scariest thing I've ever seen is a hand built chair seat cutter that cuts with a curved blade mounted in a wooden arbour, mounted in a table. This was obviously designed by your suicidal great uncle Seamus.
I'm in Canada and my tablesaw can't take any dado larger than 3/4 inch... because of the arbour. I don't understand why they won't allow Dado stacks in the EU. But then again there's lots of stuff here that makes zero sense to me.
@@answeris4217 I'm in Portugal and I have one. no issues. it's legal. it's just not legal to sell in EU. didn't bought in EU. doesn't comply with EU regulations. it's not like someone is going to arrest if you own or use one. you do whatever you want. EU just doesn't allow it to be sold in EU because it's obviously dangerous
Over 50 years experience in woodworking including owning a major furniture manufacturing company on the west coast. Used properly the existing dado set never presented a problem. We made sure the carbide on the blades were not chipped and were sharp. We staggered the interior blades which resulted in a cleaner cut. The outer blades and more teeth than this new dado set. We did have saw sharpening company come twice a week to service all our cutting tools. We even made our own moulder knives. The new set is rogress I guess but seems like a lot of fuss over a pretty benign situation.
@@keith7630 ...Thanks, Keith, for the follow-up. I don't do my woodcrafts like I used to do; I am now a full time, everyday sub at the local High School and that keeps me occupied...lol..!! And if/when I get back to my woodcrafts, I will continue to use the Dado set I already have. The blades are still real sharp ( I think I had them resharpened a few years ago ), and I didn't mind taking the time to carefully put the blades together on the arbor. I had a whole careers worth of rushing and meeting deadlines and stressing out, and I wasn't about to do the same thing with my hobby...!! But....if my Dado set were to finally get dull again, I would consider getting a set like these. I will assume that now, other companies will start developing their own version of lockable Dado blades, if there are not already other companies that produce one.
I've shied away from adding a dado stack to my shop... I may be placing an order for one of these soon. I love the CMT blade I got from Tay Tools, so I'm sure I'll love this new addition too!
This channel has become the QVC of wood working. Which is fine. I do learn about various tools I may not have heard of, but I’m clear that I’m being SOLD to every time I watch this content. Let’s not pretend otherwise. I enjoy the channel.
Yeah I don’t understand why woodworking channels seem to be overlooked by TH-cam advertising rules. Not just this one, but many others have so much non-disclosed promotional material which is just fully in violation of TH-cam terms. I guess they’re going with the ‘it’s not against the rules if you don’t get caught’ approach!
@@qoractus6659Because channels like this abuse the fact that old timers without sponsorship love to shout-out their workhorses. So this guy doing a presumably paid product demo is suddenly "normal content", not at all a product demo.
unsubscribed on this particular video because of this. YAWN. Sometimes I want to research new tools, the rest of the time I want to see cool stuff. Not worth a subscribe.
All the discussion of regulations aside, I’ve been hesitant to invest in a dado stack largely because of the cumbersome setup and having to install all the individual pieces of a “traditional” dado stack one by one. Being able to install this as one complete stack all at once is a game changer in my view. I’ve usually done grooves with my router but this has me seriously thinking about investing in this product.
Setup is somewhat time consuming for a lot of different cuts on a table saw (rip blade, cross cut blade or combo). Cutting with a dado set is quicker than many passes with a single blade or setting up a router to cut a dado using a guide. If you make cabinets, a dado set pays for itself but a cheap dado set isn't worth the tearout and burning.
Ya, it is a pain. Every time (both) I’ve gotten mine out, I think man, by the time I get this out and put it back, I could have just made 400 quick passes with my thin kerf blade.
I'm glad that you explained the issues with the older Dado stacks and yes that's a much better design. I think this is such a slick system. When I tried to pick up a set on your link and they're sold out... I'm on the waiting list.
In the UK in a commercial setting we can’t remove the riving knife or blade guards for any cut, so no dado blades, regardless of how the blade is made.
Imagine just going about your life letting your f****** government tell you if you can or can't take an angle grinder guard off or saw guard off etcetera or any other kind of thing I'm glad my anscetors came to America. Even with the doom on the horizon lol
It's not the riving knife that's the problem it's the crown guard no different to making a groove with a router or spindle moulder you still have to have a guard to protect the user it's groove not a through cut same as a trenching blade on a cross cut saw
Just ordered one from ACME Tools! Thanks so much for sharing Matt! I have the Freud Dado Stack and I am always scared when using that thing. This looks so much safer and a huge time saver. I also hated installing that thing with the chippers... too cumbersome.
Your master class is the first one I've EVER considered taking and not just for woodworking either, but unfortunately I am unable to afford it at this time. I wish you and everyone the absolute best! Maybe one day down the road I can be a part of it!
Still have the wobble dado blade that came with an old shopsmith i bought. I tried it once out of curiosity, and that thing looks like it's it's about to fling shrapnel every which way when it's actually working properly!
Thanks for another informative video, Matt. It's not likely that I'll give up my Forrest Dado King set at my advanced age, but if I were starting over, I could see me getting the CMT set. I did notice in the video that you set the carbide tipped outer blade directly onto the cast iron saw table top. That was always a "No No" for me when teaching my students how to change blade setups. I always had them place a piece of scrap under the blades so as to not potentially chip a tooth by slapping them against the iron top of the saw.
I already have a dado stack but this looks very interesting in how it keeps the teeth positioned correctly. The only downside on my saw, the Delta 36-725, is if the stack is built outside of table saw. It might be a bit tight to get it on the arbor with that dust shroud down below. Matt, have you seen that nut/washer combo from Woodpeckers for SawStop saws? They've made the two into one piece so that SS saws can handle thicker stacks. Sometimes people, myself included, have not used the washer on thicker stacks but this item from WP's looks really good.
Thank you for this. Also you have a natural ability for you tubing that is enlightening and fun at the same time. Good on you for progressing upwards! Have fun!
I'm in Ireland using a Laguna Fusion 3 table saw which I bought 3 years ago specifically as it supported Dado Stacks. Again, as many have said here its not illegal to buy a dado stack, just 'using' one can be a grey area. I for one welcome this new dado stack and look forward to trying one out. Anything that helps improve safety get my vote! Now if only Sawstop would sell cheaper table saws too!
In the EU (more specifically the UK which actually left the EU), table saws don't have an arbour that is long enough for a dado stack. That's how they stopped people from using them.
i feel every time i see an american talk about dado stacks being banned in europe they NEVER actually do any research and just spout bs constantly. its exactly what you said, arbor size regs, not banned dado stacks. standard american stupidity
@@schrodingerscat1863 I know, but the comment was saying there are no saws in the EU that can take a dado. There are actually quite a few. PS - the cheapest is £1199 or so which is close to hobby trade up price level.
In the UK most Jobsite and Cabinet saw arbors are made too short for dado stacked blades, for the express purpose of preventing their use. I bought a US manufactured Table saw X-Calibur and a Freud Diablo dado stack also from the US, I have Imperial Incra rules an Incra jig, and an Incra Mitre 1000 SE Mitre gauge/ fence. I love Rockler, we have nothing like that here in the UK. Great video, liked and subbed❤👍🪓🪚
I've had my eye on that new CMT dado stack for a while now. Cool review. You didn't mention the elephant in your shop: does this stack work with SawStop table saws. We could infer from your video that it does, but you could be running your SawStop in bypasss mode. A little verbal mention about SawStop compatibility would help clarify.
I live in Finland and have been using one of these (purchased on line from a dealer in the EU) for a couple of years now. Sometimes I have issues with vibration but loosen the nut and give it a wiggle and you are typically good to go. Great dado set!
I use dado blades on on saw to cut the joints on the drawers. I made a zero clearance throat plate for the two blades cutting the 1/4” wide and 1/4” deep joints. Cabinets and furniture has several drawers on nearly everything.
Just ordered to replace my Harbor Freight set. Not a bad set just lacks precision in cutter diameters. Curios, were the people in the EU allowed to use wobble dado blades? It has only 1 blade so no collision fears. Have a blessed weekend and keep up the work/videos! Rickster
Awesome! I just ordered one. I already have one of those older style dado stacks (exact same one you have) and I hated using that thing so much that I just usually would take the 10 passes on a regular blade instead
I actually had a dado blade that had a dial that you could 'dial' in the value. It was two blades that would wobble. I used it a few times and it did work but I don't like things that wobble.
Very interesting, I would suggest that people check not only the length of their arbor but also the diameter. A common job site saw in the EU was the Bosch PTS10. the arbour is 30mm in diameter.
It might be possible to get around the "arbor is too short" problem. It seems like it might be possible to make the nut that holds the blade in place, something like a T nut that would fit inside a blade with an enlarged hole and that would screw over the arbor thread. The nut would have a shoulder that is wider than hole in the blades that lower part of the T nut fits through. Tightening this nut would clamp the blades into the arbor.
we had the old style dado blade in our shop when i started my apprenticeship in the early nineties, they scared me back then, like the do today :D really like the design of the locked one
Wasn't there a dado set sold a few years ago where you dialed in the setting you wanted and the width of the dado it cut varied as you turned the dial?
I have been using an Oshlun brand Dado set for many years and I have never had any of the blades slip. I make absolutely certain that each blade clears the one before it and before I tighten the nut down good & tight, I double check that the blades are still properly spaced. I do, however, like this new way of making a Dado set. I looked them up and on sale, it costs about $145.00. I think that is a very reasonable price for what looks like a great way to lock the blades in place. I am curious about the durability of this new system over a number of years.
In middle school we had a whole section dedicated to the dangers of the dado. 40 years later and I still follow those rules. Do they even have shop class in schools these days?
I remember way back in the 1980 s using a wobble dado blade . It wobbled up too about an inch wide .That thing seemed very dangerous to me but nothing bad ever happened. Of course we had it on a 300 pound porter cable saw . I bet one of these plastic shop saws we have now would dance across the room.
As you said, the regulations in the EU are about the time it takes to spin down after cutting the power. Any table saw sold in the EU has to come to a stop within 3 seconds after hitting the off switch. Most machines are designed to do so with a standard blade. A dado stack with far more weight than a single blade has, will need significantly more time to spin down. If you want to use dado blades though the manufacturer explicitly warns about the use of blades which do not comply with their recommendations, you may do so in a hobby environment, but not in a business workshop (because of the rules of accident prevention). If in doubt, you can check the spindown time with a stop watch. If it is less than 3 seconds, you are safe (on the legal side). Greetings from Germany, Marcus Disclaimer: I am not a lawyer, this is just what I read from the applying laws in my country.
at 6:28 one other point, and reason for banning this 'dado stack' is the proliferation of affordable spindle moulders, which do this job safer, as you have a fence, and guards the whole way round the stock, and it is done by 2/3 cutter blades, so quicker, and more space, as said earlier also they are bolted more solidly to the spindle (the spindle is also thicker); but also these have auto feeders, similar to thicknessers, so your hands DON'T need to touch the wood, necessarily, depending on the cut being completed at the time.
First & foremost, Thank you for taking the time to produce & share this video with us, i appreciate you & Amy. I was a Diablo blade fanboy, I admit it lol. But, once I tried my first CMT table saw blade after watching a video of yours it’s been, “Diablo? Diablo who?’ 😊
My previous understanding of EU Dado situation: There are stopping requirements for blades in the EU and it is difficult to meet that requirement with a dado blade so EU table saws don't usually have an arbor that is long enough to mount a dado stack on. Also BREXIT might have affected something on this as well. FWIW, I remain confused.
Yes, I thought all EU table saws had the shorter arbors for exactly that reason. So how are people going to fit these? Plus, I can't see the EU changing the law to allow commercial workplaces to start removing the guard.
It is not difficult to meet the stopping time, you just use an electromagnetic brake. The problem is stopping a dado blade that fast would tend to make the nut holding the blade on come loose. You would have to change to some sort of quick fit retention mechanism (which would be no bad thing IMHO) but it was cheaper/easier to just make the arbour too short for a dado blade.
@@jonathanbuzzard1376 We always get the short end of the stick here in the UK (and Europe). But to be fair, I can't really blame the manufacturers in this instance. I bet the number of people who own a table saw here in the Uk is miniscule compared to the USA. We just don't have the room in our small houses/garages.
Thanks for sharing. I just got a set. What I don't have is a insert for zero clearance for my new CMT Dado stack. Any suggestions? I have a Craftsmen Pro 10" Table saw
Nice set. I had no idea they as getting banned. I have a old craftsman set that is built together and you spin the blades in opposing direction and it gets wider or skinnier. Many folks hate this style but I got mine with my saw used and I seldom use it but it does a good job. Most the time anymore I use a router anyway. But forsure the sound coming off of a stack is very scary if not use to it.
thanks Matt. I am looking into getting a dado stack and will follow your recommendation. I should be able to get a lot of practice learning some joints. I am on vacation for a couple weeks from chemo.
Very informative video. Thanks 🙂Beyond my price range here in the UK. Some resellers selling them for up-to £340 (about $430) including sales tax. For that price I'd be expecting them to come and cut the wood for you ;-)
I have a very nice Amana dado set but I can't cut a dado less than 1/4". Not sure if 1/4" plywood is made anymore but the UV plywood I buy for cabinet back panels is 0.185" thick, so 15/64" (0.234375") gets me closer but still not there.
Whats normally the advantage of a blade with more teeth? It generally provides a smoother cut. The reason, assuming your feed rate is the same, each tooth takes a smaller bite, reducing tearout, especially on crosscut grain. So if you have a dado set with few teeth on the outside blades, like this new set shown in this video, you should probably feed the wood slower if tearout is an issue. The traditional dado sets sold in the US that include a higher outside blade tooth count, should provide a smoother cut along the edges.
More teeth requires more power. Bigger diameter requires more power. Most dados don't need a smooth-as-silk finish, it's getting glued. I have a 7-1/4 circular saw blade with 3 teeth. Fewer teeth cut faster with less power. I have had a CMT, carbide, dado set for years for use on my radial arm saw. It is a 6" 24 tooth. CMT says a 6" 24 tooth should be used on a saw with at least 3 HP. They also say that an 8" should be used with 4 HP or more. I totally agree with that. After using mine for all types of wood, my 6" would be a lot easier to use and safer with 4HP. My son-in-law has stopped his 10" 2.25 HP table saw with his 8" dado set trying to take too big of a bite. I have nearly stopped my 3 HP with a 6"; and it is sharp. Don't get an 8" unless you have the power to run it properly, or you like being disappointed. P.S. A 6" dado set will cut Deeper than you will Ever need to cut.
Four teeth is more than enough. Compare with the table mill where two teeth (longitudinal thread) do the work at a speed of approximately 8 meters per minute. Saw blades with more teeth dull much faster.
Nothing like the old "adjustable" wobbly dado blade, and then used in a radial arm saw. I still have that dado blade, but luckily I only borrowed the radial arm saw.
Had one of those...destroyed the bushing on my dad's Montgomery Ward table saw. Using it that sheet metal based saw was bit like playing one if those vibrating toy football games we had as kids where the metal feild vivratwd and the little players vibrated randomly all over the field :) but if you closed your eyes (before cutting) you could imagine that you were flying in an open cockpit single engine with that whirring sound it makes :)
I do metalwork, not wood, but I have an old radial arm saw. Great for making straight cuts in bar stock or pipe with one of those blades that looks like a giant angle grinder blade. Also have a table saw with a metal blade on it. Rarely work with wood so I don't have many wood blades, but nevertheless I find tools interesting so I watch videos about all kinds of tools.
Ordered this back in February (from a very reputable tool dealer) and still haven't received it. Now I'm told its backordered until middle of June. Either they're really popular or they are having production issues.
Thanks Matt. Job site saws will accommodate dado stack blades but due to less power a 6" is the largest recommended. With that said, do you know if CMT intends on making a 6" for these saws
The fact is that dado blade per se was never BANNED in the EU. It was other things that made it ”illegal”. Most markets have their legal oddities like the law in the US making mitre saws with a ”table saw” illegal but those are allowed in the EU. For example DeWalt DW711 is just one example - and that type of a saw is an excellent saw for contrcators
My dado is a fixed set of 3 blades on a hub that expands as you counter rotate the sides, with the center blade tilting to sweep the space in between. If you spin it slowly it looks like the center blade is wobbling side to side. I guess it would never have been banned in the EU :)
I don’t even have a dado stack. Glad I don’t! Now I can get the updated version. My table saw and miter saw have CMT blades. They work great!! Thank you Mighty Matt!!
How many old style dado stacks exploded during use? My guess says someone thought it might be possible then had a law made to "protect" the rest of us. I have a dado stack set up on my older table saw. The width is perfect for 3/4 plywood so I never set it up. I simply roll it into place, run the pieces, then roll it back into the corner.
In the EU, CMT sell the 230.312.08M rather than the 230.312.08, which is 6 to 20mm. The Nominal widths table looks very similar, with spacer and shim the thicknesses being quite close, but they're not identical. For instance the 1/8" chipper is noted as being 3.14mm thick on the M set, rather than 3.175mm, so I would be interested to get vernier calipers on these to see if * they are manufactured to metric specs, with the U.S measurements being approximations; * they are manufactured to imperial specs, with the EU measurements being approximations; or * they manufacture them to both metric and imperial specs rather than just varying the documentation.
Not sure you’ll see this but I’d love more info about setting up a dado stack on the saw. Not sure there is enough to make a whole video about. With a saw stop do you need to have the dado break?
I had to do the quick math. 457 passes of 1/8" blade is 57.125". If you make a pass every single second, you can get the job done in less than 8 minutes. That's a pretty wide half lap. I definitely recommend the dado stack or giving up.
Been using a Harbor Freight dado stack for years. I think I've never used the chippers and shims to only cut 1/4" groves. Of course my table saw manufacturer does not recommend dado cutting on that saw. I have a dedicated zero clearance plate for that dado stack as well.
Thanks nice tool, Format4 and C. R. Onsrud make excellant dado machines that are very safe starting at about $150,000.00 and usually costing much more, so I will be using this blade for my shop.
One problem I see with that CMT is the leftover on its cut 0:53 which can annoy people so not sure if thats user error in assembly or its part of the tool by the company. The other is if you do have older dado stacks and you do constant cuts like 1/2 inch or 3/4 then you can have those pinned together. Most the times now its not really worth dado stacks given how routers are but lap joints do tend to be the best use case for them. Then again I rather have a radial arm saw for that than do a dado stack. Radial arm saws had 2 uses that made them shine, cross cutting wide boards and doing lap joints/dados (cross cut wise). You can build a blade guard that stays fixed on them that only shows about 1 inch bottom of the blade for doing the cutting. Even have another for thicker material if you needed it.
It occurred to me that the traditional dado set can be modified by drilling and inserting an adjustable screw to allow for the expansion and locking of the set. I have three sets. This issue worries me, and I don't want to throw them!
Despite explanation of how the dado gives a flat bottom cut later in the video, both the cuts shown at 5:40 have a less-than-flat cut into the plywood. Overall, though, it appears to be a nicely designed blade.
Thats what I was thinking, definately leaves extra material in the middle which is very noticeable in some of the shots. But then at 9:18 it looks like it gives a good surface. Would love to know whats going on there.
I'm an American living in the EU, and I have a table saw here. The EU law is that ALL BLADES being used in the table saw must use a riving knife. There's no riving knife for the dado blade, so it can't be used. It's not because the dado blades are dangerous. To 'help' people comply with this law, most table saws sold in the EU have short arbors, so even if you could find a dado stack you wouldn't be able to install it. Dado blades are not illegal, but using them is.
Yes, you're right, the arbor often isn't wide enough to accept a dado stack. Also, the riving knife in the UK is taller than the top of the blade, to allow attachment of a blade guard and/or anti kickback pawls... So making partial cuts is impossible, unless the riving knife is removed. I've just got a CMT 6mm groove cutting blade that fits on a UK table saw, so I can now cut dado's, albeit thin ones, when the riving knife if removed. It makes such nice, clean, flat bottomed grooves!
@@danbeeson9564 I know, health and safety gone mad! The farse of it is though, I'd argue it makes things more dangerous, as you're likely to remove the riving knife, to make a partial cut, and then forget to put it back, when using it normally.
Something that often is misunderstood: The "illegal" aspect of dado stacks is only illegal when an employer allows employees to use dado stacks in table saws (i.e. it's legal in automated and properly enclosed machinery). A private citizen can do what they want with a dado stack, it's just an occupational safety issue.
That's not correct. There's no law saying you have to use a riving knife on a table saw. If most table saws are sold with a short Arbor, it's likely BECAUSE dado blades are much less commin here. I say if because I am right now looking at a machine for sale from a common tool store in Europe that will take a dado stack.
Most places in the world use oscillating blades to cut wider, rather than stacking multiple blades together. In fact, I've only seen dado stacks in the US.
i have a old dado blade, From Sears, That adjusts buy turning two blades to get the width you want up to one inch. The blades are tapered on an angle. no chippers to add. Are these good or bad?
Do CMT/Sawstop say those products work together? The Sawstop manual says not to use blades with non-conductive material, and at least part of the blade is made of plastic.
I emailed sawstop technical support to ask about this blade set when it was first released. Per their response, this blade set is not compatible with the sawstop braking mechanism.
@@gulzeb you do know how legal departments work right? You have to legally tell the customer that anything outside of exact specs is wrong and they don't care about aftermarket products unless they receive money. No one cares what sawstop corporate says.
@@gulzeb since you are the one that talked to them what are the exact specs that this dado doesn't meet and can you tell me why they still sell the adaptor for the sawstop if it doesn't work?
If cmt made a 8 1/4” dado blade that would be awesome for those of us that have a newer portable saws. Owning both a 10” and a 8 1/4” table saw I use the 8 1/4” more often because it does everything needed most of the time.
It's because there is so much mass spinning. The 8" dados are made for the 10" saws. You wouldn't want to have a 10" dado with that much mass spinning on a 10" table saw.
Well considering the mass on the new blade is reduced, you would think that's no longer an issue, right? The reason historically you reduced the size of the dado down one size from the size the saw is rated for, was to reduce the power required from the saw to gouge out the cut. A smaller blade requires less torque from the saw to cut through the same amount of material. This allows the saw to get through the material easier without overloading the motor.
just to point out Dado blade in the EU and UK are illegal to SELL, you can get them if you are determined, but there are two big issues, 1) you can not use one as a business or employer because you invalidate your insurance as a safety violation, and 2) the arbour on saws sold here are not long enough to accomodate them, I have a dewalt saw and its identical to the US model except for the voltage and the arbour length for this exact reason, they dont want customers using illegal blades in their products
This can be compared to the Cyber Truck, as it is now that car will never be allowed in the EU. It is not safe for pedestrians with knife-like sharp edges in front. As you say regarding this type of blade, it is not the type but the spindown time and the need to remove safety features that make them regulated. As a civilian, you can use it at your own risk. But as a business you are responsible for the worker and that is what makes them heavily regulated…
there's a youtube video - from Stumpy Nubs I think, where he explains how they were banned in most countries because the new saws all come with electronic breaking systems to stop the blade quickly when shut off, and that the extra rotating mass of the blade stack would be too much for the saws to stop rotation within a required amount of time, and/or they could cause the arbor nut to come loose and spin off the arbor. That sounded like a good enough reason for me. After seeing your video, I suppose it must just be yet another one of the reasons why they were banned. I assume that these new stacks are much lighter weight, in addition to the other improvements in order to make them stop quicker.

Anyone else flinch big time at 6:19 watching the b-roll guy almost take his hand off? During the safety talk, nonetheless! 😬
I saw that!
@@Bhallmed I dado that.. 😂
Seriously though... reaching over the SLIDINGtable of the saw to pick up a piece from behind the blade... ffs !!. 😮
I saw that too. TH-cam is full of "expert" woodworkers who do the most irresponsible stuff on table saws. There's one well known guy, who I like his channel, but he routinely will guide pieces through where his fingers are about an inch away from the blade...
With gloves on… surprised he didn’t pull back several bloody stumps.
His biggest mistake is that he has the blade set way too high. Second is baggie cuffs on his shirt. Mainly, his blade is too high.
He should use a stick to push the piece away from the blade before he puts his hand in there.
But, asking for trouble with that blade height.
Its well and good that its compliant with UNI EN847, i run a dado stack in Ireland and had to import it from the US. However, good luck finding a table saw with an extended arbour in the EU, my saw is 36 years old (I played in the box it came in). On another note, my saw has a wobble blade, you'll never know sphincter pucker until you spin up one of those badboys
That was my thought... All the EU guys I know couldn't run a dado stack even if they wanted to, either because a) their arbor isn't long enough to accept it, or b) even if it is, the riving knife isn't adjustable/removable. I guess the assumption has been dado = no-no for long enough that most equipment matches that standard.
The scariest thing I've ever seen is a hand built chair seat cutter that cuts with a curved blade mounted in a wooden arbour, mounted in a table. This was obviously designed by your suicidal great uncle Seamus.
I'm in Canada and my tablesaw can't take any dado larger than 3/4 inch... because of the arbour.
I don't understand why they won't allow Dado stacks in the EU. But then again there's lots of stuff here that makes zero sense to me.
@@answeris4217 I is about heavy dado stacks tending to spin off and get all personal when the fast stop braking that is mandatory here kicks in !
@@answeris4217 I'm in Portugal and I have one. no issues. it's legal. it's just not legal to sell in EU. didn't bought in EU. doesn't comply with EU regulations. it's not like someone is going to arrest if you own or use one. you do whatever you want. EU just doesn't allow it to be sold in EU because it's obviously dangerous
Over 50 years experience in woodworking including owning a major furniture manufacturing company on the west coast. Used properly the existing dado set never presented a problem. We made sure the carbide on the blades were not chipped and were sharp. We staggered the interior blades which resulted in a cleaner cut. The outer blades and more teeth than this new dado set. We did have saw sharpening company come twice a week to service all our cutting tools. We even made our own moulder knives. The new set is rogress I guess but seems like a lot of fuss over a pretty benign situation.
Bought this set about a year ago. I can say it’s a really nice dado set. Locks together nicely and makes nice cuts.
@keith7630...HI, how is it after a year of use? Do the blades still lock together well?
@@marbleman52
Still working well. Blades still lock together as they should and are still leaving nice cuts.
@@keith7630 ...Thanks, Keith, for the follow-up. I don't do my woodcrafts like I used to do; I am now a full time, everyday sub at the local High School and that keeps me occupied...lol..!! And if/when I get back to my woodcrafts, I will continue to use the Dado set I already have. The blades are still real sharp ( I think I had them resharpened a few years ago ), and I didn't mind taking the time to carefully put the blades together on the arbor.
I had a whole careers worth of rushing and meeting deadlines and stressing out, and I wasn't about to do the same thing with my hobby...!! But....if my Dado set were to finally get dull again, I would consider getting a set like these.
I will assume that now, other companies will start developing their own version of lockable Dado blades, if there are not already other companies that produce one.
I've shied away from adding a dado stack to my shop... I may be placing an order for one of these soon. I love the CMT blade I got from Tay Tools, so I'm sure I'll love this new addition too!

All the discussion of regulations aside, I’ve been hesitant to invest in a dado stack largely because of the cumbersome setup and having to install all the individual pieces of a “traditional” dado stack one by one. Being able to install this as one complete stack all at once is a game changer in my view. I’ve usually done grooves with my router but this has me seriously thinking about investing in this product.
Setup is somewhat time consuming for a lot of different cuts on a table saw (rip blade, cross cut blade or combo). Cutting with a dado set is quicker than many passes with a single blade or setting up a router to cut a dado using a guide. If you make cabinets, a dado set pays for itself but a cheap dado set isn't worth the tearout and burning.
Ya, it is a pain. Every time (both) I’ve gotten mine out, I think man, by the time I get this out and put it back, I could have just made 400 quick passes with my thin kerf blade.
I'm glad that you explained the issues with the older Dado stacks and yes that's a much better design. I think this is such a slick system. When I tried to pick up a set on your link and they're sold out... I'm on the waiting list.
In the UK in a commercial setting we can’t remove the riving knife or blade guards for any cut, so no dado blades, regardless of how the blade is made.
whutta nightmare
Imagine just going about your life letting your f****** government tell you if you can or can't take an angle grinder guard off or saw guard off etcetera or any other kind of thing
I'm glad my anscetors came to America. Even with the doom on the horizon lol
They, should just make a smaller riving knife to equal the smaller blade diameter.
It's not the riving knife that's the problem it's the crown guard no different to making a groove with a router or spindle moulder you still have to have a guard to protect the user it's groove not a through cut same as a trenching blade on a cross cut saw
@@garybishop3613 would an overhead blade guard be acceptable?
I just finally ordered mine the other day! Gets here Thursday!!!
Just ordered one from ACME Tools! Thanks so much for sharing Matt! I have the Freud Dado Stack and I am always scared when using that thing. This looks so much safer and a huge time saver. I also hated installing that thing with the chippers... too cumbersome.
Your master class is the first one I've EVER considered taking and not just for woodworking either, but unfortunately I am unable to afford it at this time. I wish you and everyone the absolute best! Maybe one day down the road I can be a part of it!

Still have the wobble dado blade that came with an old shopsmith i bought. I tried it once out of curiosity, and that thing looks like it's it's about to fling shrapnel every which way when it's actually working properly!
Thanks for another informative video, Matt. It's not likely that I'll give up my Forrest Dado King set at my advanced age, but if I were starting over, I could see me getting the CMT set.
I did notice in the video that you set the carbide tipped outer blade directly onto the cast iron saw table top. That was always a "No No" for me when teaching my students how to change blade setups. I always had them place a piece of scrap under the blades so as to not potentially chip a tooth by slapping them against the iron top of the saw.
CMT cutting tools are some of the best value for the money that I have found. I own both CMT saw blades and router bits.
"It has a reference chart that will stay with your blades so you don't have to worry about losing it." Challenge accepted! 😂
😆😂🤣
lol.. It's like the cardboard that comes with every plastic packaging. Everybody throws them away
I already have a dado stack but this looks very interesting in how it keeps the teeth positioned correctly. The only downside on my saw, the Delta 36-725, is if the stack is built outside of table saw. It might be a bit tight to get it on the arbor with that dust shroud down below.
Matt, have you seen that nut/washer combo from Woodpeckers for SawStop saws? They've made the two into one piece so that SS saws can handle thicker stacks. Sometimes people, myself included, have not used the washer on thicker stacks but this item from WP's looks really good.
Thank you for this. Also you have a natural ability for you tubing that is enlightening and fun at the same time. Good on you for progressing upwards! Have fun!
I'm in Ireland using a Laguna Fusion 3 table saw which I bought 3 years ago specifically as it supported Dado Stacks. Again, as many have said here its not illegal to buy a dado stack, just 'using' one can be a grey area. I for one welcome this new dado stack and look forward to trying one out. Anything that helps improve safety get my vote! Now if only Sawstop would sell cheaper table saws too!
Thank you for the information about CMT dad stacks and the review. Excellent as usual, Matt! 😊😊😊❤❤❤
In the EU (more specifically the UK which actually left the EU), table saws don't have an arbour that is long enough for a dado stack. That's how they stopped people from using them.
i feel every time i see an american talk about dado stacks being banned in europe they NEVER actually do any research and just spout bs constantly. its exactly what you said, arbor size regs, not banned dado stacks. standard american stupidity
Some do...
@@415volts hey, you can't expect people to do some actual research, do you :-)
@@415volts Only the high end pro table saws do, saws used by hobbyists and even many professional level saws don't.
@@schrodingerscat1863 I know, but the comment was saying there are no saws in the EU that can take a dado. There are actually quite a few. PS - the cheapest is £1199 or so which is close to hobby trade up price level.
In the UK most Jobsite and Cabinet saw arbors are made too short for dado stacked blades, for the express purpose of preventing their use.
I bought a US manufactured Table saw X-Calibur and a Freud Diablo dado stack also from the US, I have Imperial Incra rules an Incra jig, and an Incra Mitre 1000 SE Mitre gauge/ fence. I love Rockler, we have nothing like that here in the UK. Great video, liked and subbed❤👍🪓🪚
I've had my eye on that new CMT dado stack for a while now. Cool review. You didn't mention the elephant in your shop: does this stack work with SawStop table saws. We could infer from your video that it does, but you could be running your SawStop in bypasss mode. A little verbal mention about SawStop compatibility would help clarify.
I live in Finland and have been using one of these (purchased on line from a dealer in the EU) for a couple of years now. Sometimes I have issues with vibration but loosen the nut and give it a wiggle and you are typically good to go. Great dado set!
I use dado blades on on saw to cut the joints on the drawers. I made a zero clearance throat plate for the two blades cutting the 1/4” wide and 1/4” deep joints. Cabinets and furniture has several drawers on nearly everything.
I have an 8 inch Freud stacked dado, all the blades on my set lock. My set is about 20 years old.
Just ordered to replace my Harbor Freight set. Not a bad set just lacks precision in cutter diameters. Curios, were the people in the EU allowed to use wobble dado blades? It has only 1 blade so no collision fears. Have a blessed weekend and keep up the work/videos! Rickster
Awesome! I just ordered one. I already have one of those older style dado stacks (exact same one you have) and I hated using that thing so much that I just usually would take the 10 passes on a regular blade instead
I feel ya... same here brother, haha!

That is what you sound like.
I actually had a dado blade that had a dial that you could 'dial' in the value. It was two blades that would wobble. I used it a few times and it did work but I don't like things that wobble.
Very interesting, I would suggest that people check not only the length of their arbor but also the diameter. A common job site saw in the EU was the Bosch PTS10. the arbour is 30mm in diameter.
I always knew we couldn't have them here.. never knew WHY...
Thank you for the amazing explanation.
It might be possible to get around the "arbor is too short" problem. It seems like it might be possible to make the nut that holds the blade in place, something like a T nut that would fit inside a blade with an enlarged hole and that would screw over the arbor thread. The nut would have a shoulder that is wider than hole in the blades that lower part of the T nut fits through. Tightening this nut would clamp the blades into the arbor.
Your first dado in the ply was burnt in the middle because you did not get the center blade set correctly. You had it on backwards......,
WOW.... I just had to look at that again. You can clearly see it @0:59
I was wondering why the thing was cutting U-channels rather than dados.
Yes, I was hoping I wasn't the only person to notice how bad the bottom of the dado looked.
So that's what was up. I noticed it, but didn't know why it looked weird.
we had the old style dado blade in our shop when i started my apprenticeship in the early nineties, they scared me back then, like the do today :D
really like the design of the locked one
Wasn't there a dado set sold a few years ago where you dialed in the setting you wanted and the width of the dado it cut varied as you turned the dial?
Cool upgrade. I still have the 6 inch dado blade for my Craftsman table saw and knock on wood no shrapnel
... yet. Survival bias FTW!
I have been using an Oshlun brand Dado set for many years and I have never had any of the blades slip. I make absolutely certain that each blade clears the one before it and before I tighten the nut down good & tight, I double check that the blades are still properly spaced. I do, however, like this new way of making a Dado set. I looked them up and on sale, it costs about $145.00. I think that is a very reasonable price for what looks like a great way to lock the blades in place.
I am curious about the durability of this new system over a number of years.
In middle school we had a whole section dedicated to the dangers of the dado. 40 years later and I still follow those rules. Do they even have shop class in schools these days?
So how do you fit the wide blade on a UK/EU compliant short arbour, which is deliberately sized to prevent thick dado blade mounting?
I remember way back in the 1980 s using a wobble dado blade . It wobbled up too about an inch wide .That thing seemed very dangerous to me but nothing bad ever happened. Of course we had it on a 300 pound porter cable saw . I bet one of these plastic shop saws we have now would dance across the room.
As you said, the regulations in the EU are about the time it takes to spin down after cutting the power. Any table saw sold in the EU has to come to a stop within 3 seconds after hitting the off switch. Most machines are designed to do so with a standard blade. A dado stack with far more weight than a single blade has, will need significantly more time to spin down. If you want to use dado blades though the manufacturer explicitly warns about the use of blades which do not comply with their recommendations, you may do so in a hobby environment, but not in a business workshop (because of the rules of accident prevention). If in doubt, you can check the spindown time with a stop watch. If it is less than 3 seconds, you are safe (on the legal side).

Disclaimer: I am not a lawyer, this is just what I read from the applying laws in my country.
at 6:28 one other point, and reason for banning this 'dado stack' is the proliferation of affordable spindle moulders, which do this job safer, as you have a fence, and guards the whole way round the stock, and it is done by 2/3 cutter blades, so quicker, and more space, as said earlier also they are bolted more solidly to the spindle (the spindle is also thicker); but also these have auto feeders, similar to thicknessers, so your hands DON'T need to touch the wood, necessarily, depending on the cut being completed at the time.
I have yet to use mine. But, I will be working on a build-in bookshelf soon and will get the chance.
First & foremost, Thank you for taking the time to produce & share this video with us, i appreciate you & Amy. I was a Diablo blade fanboy, I admit it lol. But, once I tried my first CMT table saw blade after watching a video of yours it’s been, “Diablo? Diablo who?’ 😊
I have never used a Dado set because I was a little leery of the setup. This is a Dato that I would feel comfortable using. I'm going to order one.
I used mine once. I hate changing blades, so I just make multiple cuts with the blade that is already mounted on the saw.
Woodworker I'm not.
My previous understanding of EU Dado situation: There are stopping requirements for blades in the EU and it is difficult to meet that requirement with a dado blade so EU table saws don't usually have an arbor that is long enough to mount a dado stack on.
Also BREXIT might have affected something on this as well.
FWIW, I remain confused.
Yes, I thought all EU table saws had the shorter arbors for exactly that reason. So how are people going to fit these? Plus, I can't see the EU changing the law to allow commercial workplaces to start removing the guard.
It is not difficult to meet the stopping time, you just use an electromagnetic brake. The problem is stopping a dado blade that fast would tend to make the nut holding the blade on come loose. You would have to change to some sort of quick fit retention mechanism (which would be no bad thing IMHO) but it was cheaper/easier to just make the arbour too short for a dado blade.
@@jonathanbuzzard1376 We always get the short end of the stick here in the UK (and Europe). But to be fair, I can't really blame the manufacturers in this instance. I bet the number of people who own a table saw here in the Uk is miniscule compared to the USA. We just don't have the room in our small houses/garages.
Thanks for sharing. I just got a set. What I don't have is a insert for zero clearance for my new CMT Dado stack. Any suggestions? I have a Craftsmen Pro 10" Table saw
Nice set. I had no idea they as getting banned. I have a old craftsman set that is built together and you spin the blades in opposing direction and it gets wider or skinnier. Many folks hate this style but I got mine with my saw used and I seldom use it but it does a good job. Most the time anymore I use a router anyway. But forsure the sound coming off of a stack is very scary if not use to it.
thanks Matt. I am looking into getting a dado stack and will follow your recommendation. I should be able to get a lot of practice learning some joints. I am on vacation for a couple weeks from chemo.
Very informative video. Thanks 🙂Beyond my price range here in the UK. Some resellers selling them for up-to £340 (about $430) including sales tax. For that price I'd be expecting them to come and cut the wood for you ;-)
I have a very nice Amana dado set but I can't cut a dado less than 1/4". Not sure if 1/4" plywood is made anymore but the UV plywood I buy for cabinet back panels is 0.185" thick, so 15/64" (0.234375") gets me closer but still not there.
Whats normally the advantage of a blade with more teeth? It generally provides a smoother cut. The reason, assuming your feed rate is the same, each tooth takes a smaller bite, reducing tearout, especially on crosscut grain. So if you have a dado set with few teeth on the outside blades, like this new set shown in this video, you should probably feed the wood slower if tearout is an issue. The traditional dado sets sold in the US that include a higher outside blade tooth count, should provide a smoother cut along the edges.
More teeth requires more power. Bigger diameter requires more power. Most dados don't need a smooth-as-silk finish, it's getting glued. I have a 7-1/4 circular saw blade with 3 teeth. Fewer teeth cut faster with less power.
I have had a CMT, carbide, dado set for years for use on my radial arm saw. It is a 6" 24 tooth. CMT says a 6" 24 tooth should be used on a saw with at least 3 HP. They also say that an 8" should be used with 4 HP or more. I totally agree with that. After using mine for all types of wood, my 6" would be a lot easier to use and safer with 4HP. My son-in-law has stopped his 10" 2.25 HP table saw with his 8" dado set trying to take too big of a bite. I have nearly stopped my 3 HP with a 6"; and it is sharp.
Don't get an 8" unless you have the power to run it properly, or you like being disappointed.
P.S. A 6" dado set will cut Deeper than you will Ever need to cut.
Four teeth is more than enough. Compare with the table mill where two teeth (longitudinal thread) do the work at a speed of approximately 8 meters per minute. Saw blades with more teeth dull much faster.
Interesting. Would like if you showed the shims and how they are integrated. 👍
Ny dude kept it quick, concise, and detailed!
Nothing like the old "adjustable" wobbly dado blade, and then used in a radial arm saw. I still have that dado blade, but luckily I only borrowed the radial arm saw.
I still have one of those wobble blades. It stays on the shelf.
Had one of those...destroyed the bushing on my dad's Montgomery Ward table saw. Using it that sheet metal based saw was bit like playing one if those vibrating toy football games we had as kids where the metal feild vivratwd and the little players vibrated randomly all over the field :) but if you closed your eyes (before cutting) you could imagine that you were flying in an open cockpit single engine with that whirring sound it makes :)
I do metalwork, not wood, but I have an old radial arm saw. Great for making straight cuts in bar stock or pipe with one of those blades that looks like a giant angle grinder blade. Also have a table saw with a metal blade on it. Rarely work with wood so I don't have many wood blades, but nevertheless I find tools interesting so I watch videos about all kinds of tools.
Ordered this back in February (from a very reputable tool dealer) and still haven't received it. Now I'm told its backordered until middle of June. Either they're really popular or they are having production issues.
Thanks Matt. Job site saws will accommodate dado stack blades but due to less power a 6" is the largest recommended. With that said, do you know if CMT intends on making a 6" for these saws
The fact is that dado blade per se was never BANNED in the EU. It was other things that made it ”illegal”. Most markets have their legal oddities like the law in the US making mitre saws with a ”table saw” illegal but those are allowed in the EU. For example DeWalt DW711 is just one example - and that type of a saw is an excellent saw for contrcators
Will it work on the Dewalt 10 inch table saw?
My dado is a fixed set of 3 blades on a hub that expands as you counter rotate the sides, with the center blade tilting to sweep the space in between.
If you spin it slowly it looks like the center blade is wobbling side to side.
I guess it would never have been banned in the EU :)
will the CMT work for the dewalt 7485 contractor saw?
I don’t even have a dado stack. Glad I don’t! Now I can get the updated version. My table saw and miter saw have CMT blades. They work great!! Thank you Mighty Matt!!
I’ve never seen a DADO, but I know the, also banned, swiveling saw blades that do the same. They are angled to oscillate and make broad cuts.
I'm old school. Been using wobble dados for 40 years. Never a problem.
How many old style dado stacks exploded during use?
My guess says someone thought it might be possible then had a law made to "protect" the rest of us. I have a dado stack set up on my older table saw. The width is perfect for 3/4 plywood so I never set it up. I simply roll it into place, run the pieces, then roll it back into the corner.
In the EU, CMT sell the 230.312.08M rather than the 230.312.08, which is 6 to 20mm.
The Nominal widths table looks very similar, with spacer and shim the thicknesses being quite close, but they're not identical. For instance the 1/8" chipper is noted as being 3.14mm thick on the M set, rather than 3.175mm, so I would be interested to get vernier calipers on these to see if
* they are manufactured to metric specs, with the U.S measurements being approximations;
* they are manufactured to imperial specs, with the EU measurements being approximations; or
* they manufacture them to both metric and imperial specs rather than just varying the documentation.
Not sure you’ll see this but I’d love more info about setting up a dado stack on the saw. Not sure there is enough to make a whole video about. With a saw stop do you need to have the dado break?
Interesting that they make a point about it being EU compliant but give stacking measurements in Imperial.
Do they not make them with the twist adjustment in the middle I’ve had my blade for 20 years and it works perfectly
Dado stack is the old style?
I leaned cabinetry with the dado blade that looks like a screw and has a clock in the middle.
I had to do the quick math. 457 passes of 1/8" blade is 57.125". If you make a pass every single second, you can get the job done in less than 8 minutes. That's a pretty wide half lap. I definitely recommend the dado stack or giving up.
Is this compatible with the Dewalt 8 1/4 inch table saw? I heard the arbor is too short for all other dado stacks.
Been using a Harbor Freight dado stack for years. I think I've never used the chippers and shims to only cut 1/4" groves. Of course my table saw manufacturer does not recommend dado cutting on that saw. I have a dedicated zero clearance plate for that dado stack as well.
Thanks nice tool, Format4 and C. R. Onsrud make excellant dado machines that are very safe starting at about $150,000.00 and usually costing much more, so I will be using this blade for my shop.
Does it come in a 6 inch set? I've never used a a inch set as I never needed a Dado to cut that deep.
One problem I see with that CMT is the leftover on its cut 0:53 which can annoy people so not sure if thats user error in assembly or its part of the tool by the company. The other is if you do have older dado stacks and you do constant cuts like 1/2 inch or 3/4 then you can have those pinned together. Most the times now its not really worth dado stacks given how routers are but lap joints do tend to be the best use case for them. Then again I rather have a radial arm saw for that than do a dado stack. Radial arm saws had 2 uses that made them shine, cross cutting wide boards and doing lap joints/dados (cross cut wise). You can build a blade guard that stays fixed on them that only shows about 1 inch bottom of the blade for doing the cutting. Even have another for thicker material if you needed it.
It occurred to me that the traditional dado set can be modified by drilling and inserting an adjustable screw to allow for the expansion and locking of the set. I have three sets. This issue worries me, and I don't want to throw them!
Been watching for a while…just starting to enjoy them
I need a table saw. Any Recommendations?
Despite explanation of how the dado gives a flat bottom cut later in the video, both the cuts shown at 5:40 have a less-than-flat cut into the plywood. Overall, though, it appears to be a nicely designed blade.
Thats what I was thinking, definately leaves extra material in the middle which is very noticeable in some of the shots. But then at 9:18 it looks like it gives a good surface. Would love to know whats going on there.
The central blades are maybe mounted backwards, what would explain the burn marks
What about the wobble dato blade? Was it not in compliance?
I'm an American living in the EU, and I have a table saw here. The EU law is that ALL BLADES being used in the table saw must use a riving knife. There's no riving knife for the dado blade, so it can't be used. It's not because the dado blades are dangerous. To 'help' people comply with this law, most table saws sold in the EU have short arbors, so even if you could find a dado stack you wouldn't be able to install it. Dado blades are not illegal, but using them is.
Yes, you're right, the arbor often isn't wide enough to accept a dado stack. Also, the riving knife in the UK is taller than the top of the blade, to allow attachment of a blade guard and/or anti kickback pawls... So making partial cuts is impossible, unless the riving knife is removed.
I've just got a CMT 6mm groove cutting blade that fits on a UK table saw, so I can now cut dado's, albeit thin ones, when the riving knife if removed. It makes such nice, clean, flat bottomed grooves!
That’s bizarre since there is no need or purpose to having a riving knife with a dado blade since it does not make a through cut.
@@danbeeson9564 I know, health and safety gone mad! The farse of it is though, I'd argue it makes things more dangerous, as you're likely to remove the riving knife, to make a partial cut, and then forget to put it back, when using it normally.
Something that often is misunderstood: The "illegal" aspect of dado stacks is only illegal when an employer allows employees to use dado stacks in table saws (i.e. it's legal in automated and properly enclosed machinery). A private citizen can do what they want with a dado stack, it's just an occupational safety issue.
That's not correct. There's no law saying you have to use a riving knife on a table saw. If most table saws are sold with a short Arbor, it's likely BECAUSE dado blades are much less commin here. I say if because I am right now looking at a machine for sale from a common tool store in Europe that will take a dado stack.
Most places in the world use oscillating blades to cut wider, rather than stacking multiple blades together. In fact, I've only seen dado stacks in the US.
i have a old dado blade, From Sears, That adjusts buy turning two blades to get the width you want up to one inch. The blades are tapered on an angle. no chippers to add. Are these good or bad?
Do CMT/Sawstop say those products work together? The Sawstop manual says not to use blades with non-conductive material, and at least part of the blade is made of plastic.
I emailed sawstop technical support to ask about this blade set when it was first released. Per their response, this blade set is not compatible with the sawstop braking mechanism.
I just checked and you can swap out the base cartridge for Sawstop with a Dado compatible one to make it work with Sawstop
@@trigunstudios217 sawstop has restrictions on what type of dado stacks should be used. This one does not meet those requirements.
@@gulzeb you do know how legal departments work right? You have to legally tell the customer that anything outside of exact specs is wrong and they don't care about aftermarket products unless they receive money. No one cares what sawstop corporate says.
@@trigunstudios217 I care. Also, your response is uninformed, because there are plenty of "aftermarket" dado sets that meet their requirements
@@gulzeb since you are the one that talked to them what are the exact specs that this dado doesn't meet and can you tell me why they still sell the adaptor for the sawstop if it doesn't work?
If cmt made a 8 1/4” dado blade that would be awesome for those of us that have a newer portable saws. Owning both a 10” and a 8 1/4” table saw I use the 8 1/4” more often because it does everything needed most of the time.
All you do is get me to buy more stuff I didn't realize I needed!
I'm sure this is a dumb question, but is an 8" Dado blade supposed to be used on a 10" table saw? Is there a 10" version of this Dado blade?
It's because there is so much mass spinning. The 8" dados are made for the 10" saws. You wouldn't want to have a 10" dado with that much mass spinning on a 10" table saw.
@@731Woodworks Thanks Matt! I appreciate all that you do!
Well considering the mass on the new blade is reduced, you would think that's no longer an issue, right? The reason historically you reduced the size of the dado down one size from the size the saw is rated for, was to reduce the power required from the saw to gouge out the cut. A smaller blade requires less torque from the saw to cut through the same amount of material. This allows the saw to get through the material easier without overloading the motor.
just to point out Dado blade in the EU and UK are illegal to SELL, you can get them if you are determined, but there are two big issues, 1) you can not use one as a business or employer because you invalidate your insurance as a safety violation, and 2) the arbour on saws sold here are not long enough to accomodate them, I have a dewalt saw and its identical to the US model except for the voltage and the arbour length for this exact reason, they dont want customers using illegal blades in their products
Will this work on the evolution table saw?
I need that Shirt ! 😂
...my Panel Saw won't accept a Dado Stack.. dang it!
These look way more efficient than the old-style dado setup. I had to install dado blades at school once, and I hated every second of it😂
I like your GMT Master II - I got a GMT Master back in the late 80's but lost it in a divorce about 15 years ago.
This can be compared to the Cyber Truck, as it is now that car will never be allowed in the EU. It is not safe for pedestrians with knife-like sharp edges in front. As you say regarding this type of blade, it is not the type but the spindown time and the need to remove safety features that make them regulated. As a civilian, you can use it at your own risk. But as a business you are responsible for the worker and that is what makes them heavily regulated…
there's a youtube video - from Stumpy Nubs I think, where he explains how they were banned in most countries because the new saws all come with electronic breaking systems to stop the blade quickly when shut off, and that the extra rotating mass of the blade stack would be too much for the saws to stop rotation within a required amount of time, and/or they could cause the arbor nut to come loose and spin off the arbor. That sounded like a good enough reason for me. After seeing your video, I suppose it must just be yet another one of the reasons why they were banned. I assume that these new stacks are much lighter weight, in addition to the other improvements in order to make them stop quicker.
Silly question, but if they've gone to the effort to comply with the Euro Norm standard, do they have an EU/UK distributor.
Yes, a lot.
It would nice if they could make these for table saws with arbors that are too short for dado stacks
