DeWALT 745 cutting dados

- No dado stack required. Watch as I sandwich two standard blades between a thin kerf blade and cut 7 mm or slightly over 1/4" dados. All you need are 30mm -16mm Blade reducing bushes. Its a game changer . To see this in action in my workshop check out the following videos on my channel.

Just had this saw delivered and great to know i can stack blades! Great video thanks!
Indeed you can . Happy Christmas
Great video, thank you! I just ordered the same table saw and now I'm gonna have to order some blades and washers too :)
Good choice!
Very good idea sir well done ,it seams safe and the saw can handle it
Очень давно про это думал. А спросить не у кого. Спс за идею!
As long as you can get the correct blade reducing bushes it works perfectly. I use this dado system all the time .
I tried to cut dados with a single blade and it took forever. This is a great technique. Thanks!
Your most welcome and thanks for the nice comment and the subscription
This is immense, thanks! I’m wanting to do a lot of box joints but haven’t got a proper setup for my router yet, so was looking into this, and you’ve answered all my questions.
You are most welcome. I have been using this set up for 2 years now and it’s revolutionised my woodwork. I would recommend ( ZERO CLEARANCE INSERT REUSABLE ) as it compliments the dado set . Also I know its a bit cheeky but would you consider subscribing as it would really help my channel. When you get you dado system working let me know .
@@sionhughes5543 Already did mate, subscribed on the spot for content like that! Your cement floor vid is great too. And enjoyed your workshop tour. I have an even smaller space (3/4s of my garage) but have managed to cram in a surprising amount of bigger machines, although not a lot of space for manoeuvring…! Smaller, practical UK based woodwork/DIY channels are my favourite.
@@sionhughes5543 Can’t quite decide whether to spend the money on your dado stack setup or trying to properly sort out a router table setup…! But have a big heavy duty Hitachi router which is a workhorse but no raising/lowering mech, so a pain to use in a homemade table. Router lifts very expensive/Heath Robinson, thinking about selling and getting the Triton with above table raising mech built in.
Nice comments like that will get you on my Christmas list . I dream of a jointer/thickneser with a spiral cutter head and a descent band saw . Check out Axminster tools if you haven’t already.
Well I have a supper flash router table as you saw and I ended up with lots of tear out and the work bit laboured to cut through especially when your cutting 30 cuts to make a box. My dado system cost me a spare DeWALT standard blade of eBay and a thin kerf one from Axminster £15 plus blade reduction washers £5 . I have a video called HOW TO MAKE A FOUR PANEL DOOR. It shows my dado set doing stuff that you couldn’t do on a router table and even if you could it would take you 20 times longer and you would burn your router motor out.
Turning a router table into a joiner is well worth watching on the WORKSHOP TOUR
Genius! I’ve got the same saw. I’ll be giving this a go. Cheers mate 👍
It’s certainly puts a smile on my face Marc . Please consider subscribing and check out my re usable zero clearance insert, I think you might like it …..
@@sionhughes5543 I’ve already subscribed mate, I’m currently working my way through your back catalogue! Brilliant stuff! 👍
WOW, THIS IS TOTALLY AWESOME. I LOVE DEWALT TOOLS. And I would love to have one of these. But I have to stick with my little smaller tools. But at least now I know how to do this.
It’s a great little saw . I am very fortunate to have one.
Looks very interesting. I have the same model of saw but haven't really finished setting up my workshop so will have to remember this trick. I have subscribed though so will be looking at any other ideas you have shared. Thank you
I am going to follow this video up with some DW745 upgrades .
@@sionhughes5543 And there was me, thinking the dw745 WAS an upgrade! I shall watch with intetest...
Hi, I have the same model but I never knew can use 3 blades for dados cut.excellent
Hi Elvis , Glad you liked the video . I have a whole playlist on the DeWALT 745 love to know what you think off the other videos . Cheers sion
Hi there I liked n subscribed!!! So I have DEWALT 78450 type 4. Yes the male end is a like short n can only go on cutter in between. That works. When I tried a wider stack this issue was more of a plastic piece limiting the width. Across
From where the guard tightened is rything blade. I was able to take the case off n all it is is a plastic piece
Since DEWALT already says no, I was gonna cut that limiter off.
Wish I had a pic to show so you could understand what I’m trying to convey.
Yes I understand now the other aspect of diameter of hole issue. Brilliant solution.
I really appreciate the kind words and I have to say that that’s the most useful adaptation. I’ve made to that machine. I’m really sorry it doesn’t work on your particular Brand but I guess the design must be slightly different from the 745 . I’ve got about 60 yard videos. Really hope you enjoy the others as well.
Thanks, just what I was looking for. I was thinking to use smaller blades as you will almost never need a full depth cut. (they will be cheaper also!)
You make a good point but the smaller the blades usually have a thinner kerf . Those blades were the standard blades that comes with the saw and they have a 3mm kerf which is as wide as it gets and suits the stack of 3 blades
Thanks for the dado tip. Just wondering, where did you get the cool looking cross cut fence?
That’s from Axminster. It’s an excellent shop for anyone who wants quality tools. Glad you enjoyed the video. I have an Axminster router table which you might enjoy in my woodwork play list . Please consider subscribing and thank you if you already have.
thks
Go to my channel and look at the Playlist for DeWALT 745 , There are a few other good videos on the table saw you might find useful. Cheers Sion
Interesting idea but ill stick to my router table. The combined weight of the blades will have an effect on the saw motor and brake over time. Sucks we can't have this option as standard in the UK.
Actually not hat long ago I had a problem and couldn’t raise my blade . I did a video on it that you can see on my DeWALT playlists. The point is when I was talking to the chap who repaired my table saw I told him about how I stacks blades .He said the same thing you did but then added that having pulled my machine to pieces that it show now signs on wear as a result of my dado system. I say all of this with the understanding that I am not cutting dados 8 hours a day and that I use this set up only when I need to so its really not harmful to machine .
Hi! What brand is your miter gauge?! Do you recommend for the DWE7491RS? Thanks great video
That is an Axminster mitre gauge .
Hi Sion. Congratulations on an excellent accurate and professional video. One thing is where do I get these blades I cannot find the precise blades on Amazon and certainly not in B&Q. Are the two outside ones the standard ones which come with the machine?
Thank you for your kind comments. The outside blades are the standard ones the machine comes with . I bought the second one off eBay and the thin blade from Axminster . Make sue the thin blade has the same TPI so that the carbide teeth don’t ever touch ,
Thankyou very much will try them. You ought to teach how to produce a video
That’s kind of you to say so however , my videos are not getting the views that I feel they should .
Visit my channel and check out the play lists (De Walt 745) and (woodwork) for examples of me cutting dados
I had a fiend doing this 30 years ago on a radial arm saw, with even more blades without carbide tips. As long as the teeth are staggered like you did with the carbide tips, it worked great. A cheap alternative to an expensive dado blade set that is a unitask wall hanger for the average home shop
It opens up a lot of time saving options . Thanks for sharing your friend’s experiences . Cheers Sion
..hello there, great idea for DIY dado. I bought the exact thin kerf blade for the middle blade. It came with 2mm washers even though the blade body is 1.2mm, my question is would it be safe to use the 2mm thick washer for the thinner blade, the middle one. I installed the 3 blades and it seems solid enough although I'm wary to use it, maybe oll wait for the thin washer to arrive in the post! thanks again
Well its been 8 months and I hope you have cut lots of dados now ?
@@sionhughes5543 ..8 months yes, a lot has happened. The thinner washers are hard to find but got an overpriced one in germany and it works really well so good job.
Theres a video of a guy who changed out his dw745 arbor for a longer dewalt arbor and now can use a dado stack, theres a little bit to it though.
@@cdunne1620 yes I too watched that video and loved the idea . I requested that very upgrade when I had my blade height Carriage casting changed . I was told that the longer part is not available to the UK . Hmmmm shame , anyway you got it working and are currently cutting dados .
Wow i didnt this it was possible to allow for dado blades on this model. I've had mine for a few years but im not very confident with it. Really should build some jigs
Thanks for the comment. It is a massive time saver and allows so many extra possibilities. Enjoy. Cheers Sion
Why did you sandwich a thinner blade in the middle (2.1mm Kerf), why not the same thickness as the other two (3mm kerf)?
Is it purely just to have a little more thread space on the arbor for the nut + washer to hold on to?
Absolutely yes . Exactly that . It works like a dream and no changes are needed to the standard machine and you can just use the original throat plate . Happy days win win win . Cheers Sion
@@sionhughes5543 The thing is i can’t find the thinner washer anymore but I have found Freud circular saw blades 184x16mm 24t can I not use these and since they are 16mm I will not need a washer and the smaller diameter has less weight on the motor. so can I make use of these 3 blades with just the bolt at the end?
Do you see a problem with this set up?
I have noticed that the blade drops a bit (the hight adjusment handle moves) when cutting dados/rabbets on my own DW745. Is there a way to prevent that, other than physically blocking the handle?
Check out a video made about ( DW 745 problems raising & lowering the blade ) It sound like the raising and lowering mechanism is warn
@@sionhughes5543 It really can't be wear, as it has done that since new, but I'll check out the video...
Edit: Nope, not the same problem.
Is it true that dado stacks are not legal in the UK. I’ve heard they are not sold there for health and safety concerns
THEY ARE LEGAL IN THE UK . The law changed a few year ago . It was mostly to do with EU standard saw not having long enough arbours and brakes on machines . All I can add to this subject is that what I have done on my DW 745 works for me . Their are a lot of useful comments in this section to read . I hope this answers your question . Please consider subscribing David
These blade reducing bushes are available at AXMINSTER .CO.UK and are on page 17 of their 2020 catalogue
hello sir were can i get them washers
Axminster.co.uk . They are inexpensive. Hope that helps. Cheers Sion
Great video! Do you have the link or site name where I could get these washers? I have the Dewalt DCS7485N-XJ 8” inch would the same concept on my saw table?
Hi, ( blade washers ) are sold at Axminstertools.com . They have a great online service .Good luck and thanks for the nice comment. Please consider subscribing and check my DeWALT play list for more table saw content . Cheers Sion
Have you found the blade washers yet ?
hi Sion, is this working correcly? i heard dewalt saying they dont approve this because the blades together are to heavy for the motor brake. Instead i use dado blades from the USA (the arbor of the blades is 16 mm, so fits without washer)
The system i demonstrated works perfectly, however a dodo set that fits a 16mm arbor is ideal . The idea of this video is to show UK people mostly that with standard blades and a couple of blade bushes they can cut dados . Happy Christmas and stay safe .
@@sionhughes5543 same Sion! Greeting from the Netherlands
@@Looyenss and a happy new year from England .
Hello , I also want to put a dado blade to my DW745 .Can you please give a link to us to buy the dado blade ?
@@emrecenkers9721 Hi, I used two standard blades and one thin kerf blade . The whole idea of this video was to show that you can cut dados without a standard dado kit which are supper rare in the UK .
do you have a website to purchase these
Axminster.co.uk . Cheers Sion
NOOICE!
Can’t get blade off. Tried pushing the spanner’s together as per instructions unscrews in the book but you demonstrate pushing spanner’s together tightens
Clockwise to tighten. Anti-clockwise to undo . Hold the spanner on the left to keep the blade shaft from spinning and with you right hand pull towards you to get it off and push to tighten.
Where can you get the special washers?
AXMINSTER .CO.UK BLADE REDUCING BUSHES . PAGE 17 OF THERE CATALOG
I bought these blade reducing bushes at Axminster .co.uk They are on page 17 of the 2020 catalog
Any ideas if this will work on the 7485 model of the DeWalt jobsite saw? It's a 8 1/2 diameter blade, so slightly different. Awesome video btw, very concise and accurate and takes the guesswork out of performing such an uncertain and potentially dangerous modification.
Hi George , I don’t know but as long as the carbide tips don’t touch and there’s enough room for the arbour nut it should be ok . Make sure the washers for the blades are the right ones and have a perfect fit
@@sionhughes5543 Thanks for the quick reply Sion. I'm just not sure if the 10" to an 8" drop will cause issues and if the arbor has the same dimensions as the 745. Some guys recommend getting a box joint cutter to cut 3/8" wide grooves and say that it will fit nicely with enough threads to tighten the nut. I guess I need to do more research. I appreciate your help sir. Thanks again and God bless.
Whats the max anyone has achieved from dadoing this table saw?
7mm
You can also buy a new arbor and put a13/16 dado on this saw
Hi Steve , I saw that video ,but its a lot of work to fit the longer arbour . Glad you enjoyed my video and I really appreciate you taking the time to comment. Cheers Sion
Watch my NEW video ………ZERO CLEARANCE INSERT REUSABLE …………. It’s a reusable throat plate for the DW745 …………..It’s completely unique
Seems to me there could be a market
Cheers , Glad you enjoyed the video . Its a real time saver . Please consider subscribing if you haven’t already.
That's great but why not use a router and router table? surely its more convenient?
High Nick . First of all thanks for the nice comment. A router has its place but for the work that I do stacking the three blades together allows me to cut dadoes far quicker and far deeper than I could ever be achieved on a router table. please consider subscribing and check out my channel for other videos. If you watch the videos on how I make doors you will see how using those three blades is way faster than trying to use a router .
Isnt this dangerous though? Arent the blades free to spin on themselves? I wouldnt want to imagine the damage when those carbide teeth collide at 3800 rpm and the bits fly into your face
No the blades are not free to spin . And if you think about it the standard blade comes with the standard blade washer supplied with the machine and works perfectly with a thin kerf blade on its own.
@@sionhughes5543 Allright, thx for the answer!
There is a safety issue with your table saw. When the saw is started, the inertia in the saw blade causes it to have an anti clockwise force and, thus, creates an undoing force on your locking nut. To overcome this my sheppach saw has a locking washer which counteracts the anti clockwise force - the locking mechanism is a flat spot on the spindle which is mirrored by a flat spot on the washer. The reason I am aware of this is because I bought a dado set many years ago and it would only go on my machine without the locking washer. It was only by fantastic luck that the flying dado did not hit me! Dado set ups are not allowed in the EU for safety reasons and that is why all our table saws have short spindles..
I take on board what you say about safety because I am very very keen on safety myself. However, just two points to make .Dado blades are completely legal in the UK and blades and machines are sold at Axminster. I realise that the DW745 wasn’t sold with a dado kit as standard but it would be if it was in the US . The arbour is shorter and that is the only difference. I have operated the 3 blade system safely for about three years now and have always found it hard to get the arbour nut off . It has never loosened itself. Their is sufficient space for the blade set up that I demonstrated in my video . Finally It’s worth mentioning that dados have been available in the UK for at least two years now .
@@sionhughes5543 I passed on the information because I wouldn't want anyone to repeat my experience. The short spindle is an EU legal requirement - their attempt to protect people from dado blades (rightly or wrongly - I am not expert enough to say). However, its interesting that you think that dado blades are legal in the UK because you can buy them at Axminster. Presumably you think Brussels has had a change of heart and repealed the legislation? Also, you deduce what I described is not a safety issue because you haven't had an accident yet and that is, of course, your prerogative. In any event good luck in your endeavours.
Your concern is legit. I think it can be greatly reduced with 7.25 inch blades instead of 10 inch ones.
@@super-z8943 good point 👍
@@sionhughes5543 Is this what BREXIT was all about? The Brits wanted to be able to use dado blades? Finally, the Brits have freedom. Congratulations,
The downfall with this is your dado is going to have ridges and not be flat. That ATB catbide design prevents it from cutting a flat bottom.
The best way to get dadoes on this saw is with a box joint set. But, that can be as pricey as a dado stack.
There are also blades with a 6.4mm (¼") kerf... but still pricey.
Before i got a ⅜ box joint set, I used a full kerf, FTG (flat top grind) from Freud. Its their heavy duty glue rip blade and its super beefy. Its 3.2mm (⅛") and it also is great at jointing , and rabbets on the table saw.
Thanks for the advice on those flat top blades . Quick question, Are you from the USA ? I only ask because I have tried really hard to find flat top blades in the UK but with no luck .
