- I missed the #woodjigs21 deadline unfortunately, but this is the penultimate crosscut sled - version Next is always better, right?
How awful is that title? Apparently this sort of thing is how to get all the clicks and views though. I hate it and feel bad for it.

Is this the *_worst_* title I've ever written?
Yes. Yes it is.
Needs more Doom.
@@FixitFingers 😭
Next time try "The ONLY ultimate crosscut sled you’ll ever need including things the BIG crosscut sled corporations WON’T let you see. MUST WATCH!"
NEW WOODWORKER thinks he's made the BEST CROSSCUT SLED EVER?
I still absolutely love my Wood Knight crosscut sled from a few years ago Paul. Thank you so much. All I need to do occasionally is make new inserts. Covers me for 90 and 45 degree cutting so well.
Excellent, excellent, excellent! Very nice crosscut sled built with minimal store bought hardware. I like the material stop. Very solid design.
Great video. Cool sled
Nice one! I accidently cut mine in half a while back, and still have to make a new one.
Mate, that's the ants pants, and he wants em back!😉😆👌🏽
Awesome sled, Paul, great build. 👍🏽
To answer your question in the title, yes, I do believe it might be, great work!
I really like the oversized hole used for squaring things up with the five cut method. My last sled looked like swiss cheese on the bottom.
Very nice. For the vacuum pump, have you considered an air conditioning / refrigeration mechanic pump? I bout a two-stage pump on eBay a few years ago and it is still going strong. It's 2CFM and pulls an almost complete vacuum. Very quiet and you can leave it running continuously for hours in case you have any bag leakages. They go for about $150 and come with standard Nitto fittings so you can use your existing air hoses as vacuum hoses.
The trouble - for my brain - is the information around those types of pumps. Some say they're fine, others say they need to be cleaned of all freon (presumably thats just *used* ones), others say they work just fine but will spit a fine mist of oil into the air and sometimes into the bag.
Because of all the conflicting info my anxiety flares up when I've looked at them! 😬
could you tell me what that clamp is when drilling at 5:00? Is that part of your drill press or stand alone?
That's part of the Bosch drill press!
I’d like to know more about the router jig that runs along the track used to cut the t slots at the two minute mark. Is it a diy item or a commercial product? Can you tell us more about it? It looks pretty cool.
Stephen, that's the Bosch OFA router attachment for the FSN rails that work with his tracksaw. If you do a search for "bosch fsn system" you should find some more info :)
G'day Paul, I'm in the market for a vacuum bag, what you using/recommend?.
I'm currently using a Roarockit Thin Air Press bag (as I write this, I'm actually inbetween glue ups!) roarockit.com.au/index.php?id_product=14&controller=product
For the glue, Roarockit just use Titebond III, but I'm using Titebonds cold press glue. Its a bit more viscous, I believe its just regular titebond + some filler to reduce "bleed through" from the vacuum process.
Do I recommend it? Well, its a really cheap entry point into vac bagging, so its not as good as the several hundred->thousand dollar systems, but its also a fraction of the price. I wasn't a fan of the sticky 'closure' that comes with it, so I made my own th-cam.com/video/jzSFkCS0_5k/w-d-xo.html
It *does* work - I've used it at least a dozen times and haven't had a failure (yet!) - but eventually I'll be looking at upgrading to a system with an actual pump for ease of use, and for use in other things like vac clamping. I don't have a good answer for *that* just yet, that I'm willing to spend the money on yet!
The Wood Knight: You might want to check out "The Grab-O", as presented by Izzy Swan, for your future vacuum clamping needs. He makes an adaptor plate which will let you use the unit as a pump for your set-up. I think you will be pleasantly surprised by its performance and versatility, even when not using it for bag clamping.
I've seen the Grabbo! It's such an... odd duck I guess is the right phrase.
Compared to "proper" vacuum pumps, its *dirt cheap* (~$400AUD locally, not sure what Izzy charges for shipping his plate)... but at 0.7CFM, it pulls half of the lowest end Vacupress model (~$660AUD 'cause of awful shipping).
A few places recommend a min of 1cfm for 4'x4' flat panels, and 3cfm for curved 4'x4' - which is likely the largest I'll be doing, but its just at that borderline. Two stage evacuation by using a vacuum to suck most of the air out first would mostly mitigate that though
But its more versatile than a regular vacuum pump because of its portability.
I'd love to setup a vacuum table for the CNC, but the run time could be an issue given batteries rather than continuous run... but the auto-start/stop of the pro model might make that a non-issue.
I keep flip-flopping on it, do you know if anybody other than Izzy and Andy have videos on it, specifically relating to veneering?
@@TheWoodKnight I have not seen any videos specifically about laminating with it, other than Izzy's. I just started using it for vacuum clamping about 2 months ago, which I don't do a whole lot of, and not near the sizes you mentioned. The biggest has been a laminated chair seat.
Sounds like you would benefit more from a higher capacity unit, particularly using a vacuum clamp for a CNC, and not really need the portability. They are really cool little units though. Wish I would've held off and got the Pro unit, but the second Izzy showed it I was hooked (had also been considering a vacuum system at the time) and placed my pre-order before the video was over.
I'm also going to be getting the drill press adaptor from Izzy as well. I do mold work for sand casting at a foundry and have often needed to drill odd holes in the middle of flask bases, where a drill press won't reach, and this will add precision/speed to a process that has been a point of vexation in the past.
@6:20 Haven't seen that mouthed so well in a long time.
How much does that thing weigh?
I haven't measured it, but napkin maths puts it at about 7-7.5kg (based on the amount of material used compared to the ~35kg/sheet for baltic birch ply). With UHMWPE tape strips on the bottom, it glides *very* smoothly, but it is a bit of a hassle to lift onto the saw compared to my old/smaller sled.
G'day Paul, Another WTF is it question!Haha!. WTF is the machine you're using to counterbore?.
For the bolts in the fence? It's the Bosch PBD40 Drill press, using a 19mm carbide tipped forstner bit. I got the bit many years ago for uhh.. I think drilling my workbench for dog holes? Carbide bits are really great for that sort of thing and I need to eventually switch my forstner collection over to them.
The drill press is itty-bitty, but reaaaally suits my drilling needs th-cam.com/video/dY61FBRF5X8/w-d-xo.html
Looks beautiful and functional but .... Isn't it heavy?
Its...manageable. Its not the lightest sled, no. That comes with any large sled unfortunately. Thankfully it glides pretty dang smoothly - some wax and UHMWPE tape on the underside really help there!
I was tempted to use falcata plywood (commonly used in RV and boat fitouts) which is a good 30-40% lighter than birch, but it dents very easily and I was trying to use up a lot of the offcuts I have laying around (which were all heavy birch).
@@TheWoodKnight cool. Thanks for the answer. I like this sled's features. Maybe I'll make mine tapered towards the back fence so less material is involved... Thanks!
Sorry, what was the purpose of the red part?
The red parts are incra's "racks" (The black versions are imperial), with teeth every 1mm. The teeth in the stop mesh with the teeth in the fence, and pull the stop one way or another so its always exactly the same measurement, to allow for fantastic repeatability.
Unfortunately, this means no microadjustment for sub-mm settings, but there are a few ideas I'm exploring when weather (and migraines) allow - shims or using a woodscrew in the stop that can be adjusted are two easy ways to add sub-mm settings.
@@TheWoodKnight ok. I thought it was an incremental thing. I'd find that problematic. Even 16mm particle board measures 16.3mm so it suprisingly adds up.
I guess we all watched Veritisium last week hey? 😄😉
I'm currently also preparing the half dozen sacrifices to please the almighty algorithms to help ;)
Title like you see some of the Yanks would use LOL. Much fancier sled than the Timbecon one you made a few years ago 😎😎
Veritasium recently put out a video on the matter (if you're interested th-cam.com/video/S2xHZPH5Sng/w-d-xo.html) - unfortunately, clickbait works and is here to stay. I *hate* it, made me feel incredibly uncomfortable but I'd really like to be able to afford one sheet of plywood a month!
As for the Timbecon sled, its more or less the same... but the really really dumb thing is if I had of just followed *my own plans* I wouldn't have had those misplaced slots for clamps! Argh! I think thats gotta be some peak dumb that I've shown 😂
@@TheWoodKnight At least you did show your 'Lapse' of concentration which proves you are humane like the rest of us LOL
I feel the need to give some criticism. Hopefully it comes across this way.
I don't want to say the video is bad. It's interesting. But as someone just finding the video in my TH-cam feed I had little frustration. The video left me very curious about many of the things you did, but also confused and without understanding of many of those things. It was a bit like watching half of a magician's trick be revealed on a "learn to do magic" video.
(Though I don't blame you for baiting the clicks with the title. "You won't believe what this Crosscut sled does!" "10 Crosscut sled tips that big table saw doesn't want you to know." "If you make a crosscut sled like this, this could happen to you!" "Take a close look at this crosscut sled and you'll see why this man divorced his wife!" "The sad final days of Nick Cage's crosscut sled.")
The video itself could use more detail.
For someone who comes to the channel regularly this low-explanation video might be standard, but for me having not seen this and having only created a couple of crosscut sleds I got a little lost occasionally.
At certain points the subtitles drop away and other than the section description I'm not sure what you're doing or why, at least until later.
It's got the "mystery build" feeling where you're supposed to be excited when it all comes together, which isn't great as a user trying to understand all the little sub-steps. As a viewer I'm forced to go back and forth in the video feed and play detective on exactly what you did.
I understand that for production reasons it's often too much work for a particular video to add spoken audio. I know too well how much work it can be to add and edit voice to video. Even in standard parts I am familiar with like doing a 5 cut test it felt like the video could have used a little more text to help us understand.
And then there are other parts like the plywood lamination I'm just not familiar with from other videos on the subject (or in general). Maybe this is standard around these parts, but it's not something I've run into during my short woodworking non-career. I would love to know more about the decision to use the 6mm on 12mm and the vacuum process for laminating. There's probably more on this channel here, but there's little discussion given to something which I have never seen.
I know you cannot prepare for every random newbie to show your doorstep and you have to keep you current peeps entertained. And not every video is a training masterpiece. I just think finding a way to clutter up the screen with some extra steps explaining things that seem like people already know would help the individual videos a lot.
I really am curious about the things that you do differently and will likely did around for more info, I just wish I had a more clear starting place here.
Ok, that seems like enough of a rant. I have to tilt a nearby windmill today.
I agree. Ive been sub to him for a while but I have no idea what the red strips were or what the process for getting the dado for the runner just rite. Sometimes he does a longrr explanation video so maybe he will
@@Ashdad99 There won't be a longer explanation for this, however its mostly the same as an old jig I made, which does have explanation/narration/free plans. th-cam.com/video/Hhyw_1uXphE/w-d-xo.html
_To address the woodworking questions..._
* As noted in the subtitles, vacuum pressing applies a literal ton of pressure per square foot. You could achieve similar effect - but obviously much lower pressure - by putting weights/tools/etc on top of the plywood to hold it down while the glue cures. Regular clamps cannot be used as they cannot reach into the middle of the board. Cauls would work, but you'd need a lot of them to apply even pressure.
* 6+12mm was used because the alternative was 18mm+routing out 6mm for the insert plates. I've done both methods in the past, and I prefer the lamination over routing - its a bit less tedious. Plus, I had 6+12mm in sufficient quantities on hand.
_On the title/cover for the video..._
Veritasium recently did a video on the matter. I hate it, but its apparently the only way to get views.
_On the lack of dialog..._
Over the past 2-3 years, any videos with dialog from me have had trended down considerably. Nobody wants to watch them. I get told that
* I talk too fast
* I talk too slow (usually in the same video!)
* I must love the sound of my own voice
* I'm indecipherable
* or a recent favourite (and this is a direct quote), "Sorry your pronouncement is not very clear articulated."
I'm trying something a bit different - focusing on the "watch me build a thing" experiences ala Ishanti and others rather than "this is how you can build a thing", trying to play to my strengths (I reminded constantly that I have a face for radio, a voice for print, and opinions for toilet paper)
@@TheWoodKnight I really appreciate your response and I feel a little bad I got you to write so much.
I want to make it clear I think that whatever knuckleheads like me think, it's most important that you create what matters to you. It would be better that you get what you want out of it.
I only generally write on a video when I think it's close and could have a few changes. Ironically I probably would have said nothing if there were no subtitles. In retrospect, I think the issue was I thought I was going to get a little more advice on a few steps based on the limited text.
Probably this was unfair on my part.
TH-cam has this sort of mono-culture problem where all videos are expected to be in a certain way. Listening to your response I feel more sympathy for what you want.
I think of it like another hobby of mine, Improv. There are certain kinds of performances that would only make sense or having meaning to people who know improv and would be inaccessible otherwise. Those things should exist but the audience will always be smaller. The biggest problem is getting the right audience in.
I can see you're having some fun with the text you put up as you go through the video which reminds me of this sort of "not level one" video, but in the TH-cam world where everything goes in the same bucket, what do you do?
Maybe the answer is to set expectations at the beginning. A reference to another video? In some sane world TH-cam channels could have categories and tags so you could do multiple things. Some people create second channels for different kinds of content. But if this is the only kind of content you want to do, you're sort of stuck in the same bucket.
I don't think you should put audio in if it's been a problem for you, and honestly that's not what I expected. Audio is tremendous work. I firmly believe audio is harder than video to get right on a video.
Also, remember the the voices in your comments always feature the noisiest of people. Most real people aren't as negative as the comments section. Even if something is fine, there are 5% who hate it. And even among those who complain, sometimes the complaints aren't meant to be as negative as they come across.
I rewrote what I did several times and I still fear I made it sound like this was bad content. It's just so easy to sound negative when you've got "brilliant" opinions.
This is content created with care and I didn't think otherwise. Enough care that there was something else I wanted from it. But it's best to make sure you can be happy with what you do. You can't buy that.
I hope you didn't endanger your half drunk bottles of wine by making that vacuum bag jig....oh wait, no one has half drunk bottles of wine; all good.
Nice one! I accidently cut mine in half a while back and still have to build a new one.
