Aye. I've no idea how I missed this video but it's taken me from unsure about what & why to clearly understanding the reasons & the process. Excellent video.
Wow...when we see the idea..we think it is so simple...but thinking about the idea we see so genial it is in simplicity itself Shaw shim it is an amazing idea by the way (with that sawblade red knife be Romeo and Juliet) Thanks for all video class and constant support Congratulations from Brazil
Thanks for showing us this in another one of your very informative videos, Rob! For me, I will need more practice on the finer aspects of woodworking, especially after hand surgeries. The Shawn Shim and your dovetail saw does make the process much more enjoyable, especially when trying to narrow the "learning curve". Your time and effort that you put into your teaching is greatly appreciated from myself and other woodworking enthusiasts that I associate with. "Cheers!"
At 6:04 did you accidentally mark the pin on the wrong side of the tail. You talked about the Sean Shim in a previous video and I had to watch it a couple times to get my head around what was going on. Only mentioning this because it might be hard for somebody trying to follow this to understand or maybe I’m wrong and still don’t get it. Magical timing. My marking saw that you’re demonstrating came in the mail today! Woohoo.
I've been using a similar technique using blue tape as the spacer. Very close, but not perfect every time. The Shawn shim is a great idea for repeatability. I'm going to measure my saw this morning when I get to the shop. Thanks for presenting another innovation.
If you sharpen and set your own saw by hand, I presume that you lose some of the precision of the kerf width. What would you recommend? Measure the kerf width after each set and stone the teeth to even the set? Measure the kerf width and adjust the offset?
Great explanation and work. Me is always told that if such a joint is too tight, the glue-up will be less stronger. How does it hold with your piece when the joint is made a but tighter? Thanks for sharing
There arecircumstances where you can "Starve" a joint of glue., but that mainly is cases of applying too much force with clamps. That is not a worry here as just friction is holding the wood together. donorbox.org/the-purple-heart-project
I employee two combat wounded soldiers, one was a tank commander, that casing was the first round he fired. We run the Purple Heart Project to help wounded Veterans. Check it out at robcosman.com
Exelente explicacion se entendio , lo que nunca me gusto es la marca que deja el gramil cuando marcan la prof por cierto ese serrucho de costilla se ve hermoso . no se por que los chicos q veo en redes usan rioba dzuki o kataba. Japoneses .cuando los costillas para mi " son hermosos y presisos
This is a useful jig. And, if you have access to a mill, quick and easy to make. No mill? With the aid of a digital caliper, it is not hard to make with a hand file. Does not have to be brass- aluminum works just as well, and is cheaper/easier to source. Instead of using a knife to make the mark, using a pointed saw (with the same kerf) that is pull-cut makes a small trough that the saw fits into- great precision.
@@RobCosmanWoodworking True. Although I have come up with an improved design that requires no machine tools to make, and both locates the parts in both planes and is easier to hold in place. Will be publishing soon.
I am really getting frustrated with dovetails lol. I have the worst case of the "can't saw straits". I'm going in the wrong direction too, meaning my tails are wider where I'm marking them and thinner where I cut them from, if that makes sense., always a gap, the worst type of gap, always from the same step, the first one, cutting square "no wood then pen, just pen " type of issues. SO, I see people starting to migrate to jigs and what not and I say, go ahead if that's helping you, me? I want to own the joint. So do jigs help you learn? I don't know why but when I watch other videos of ppl using magnetic jigs where all they have to do is move the blade back and forth, again fine, but I wonder if something like that can be helpful? At what point does it become a jig? because technically you are cutting it by hand right? but are you? if anyone reads this, let me know what you think, thanks again Rob!
Amazing. Thanks. However, you shun using a guide to hold the blade or chisel when sharpening because you can learn to do it without. But you promote using a Shaun shim and saw blade knife. How do you resolve that contradiction.
No contradiction. He understands that getting dovetails from the saw (which is possible and the most efficient way to do them) is quite complicated if you're a beginner. Once you get proficient with the set off method you may go to the traditional one. Since it's more difficult, it'd requiere your entire dedication since you already know that you can do it. I may inquire also that as a part of his business he promotes the tools he makes, which may lead to a bias from his perspective. Nevertheless you cannot talk about Rob Cosman without expressing how he has changed the handcut dovetail horizon like David Chalesworth changed sharpening, or Paul Sellers has changed woodworking itself.
The reason I recommand to learn free hand sharpening is because you can easily learn freehand sharpening and the speed at which you can sharpen your blade (32 seconds). heck every 12 year old apprentice in the 1700's learne how to freehand sharpen. You cannot move a piece of wood .024 of an inch, multiple times in a row, free hand. I think you have an apple and an orange comparison,
I’ve never been so confused about something and then have it click so hard when you explained it. This is GENIUS!
DOnt you love it when the light comes on?
Exactly. In another video I didn’t see the point the first time through and had to watch it again and then BAM!
Aye.
I've no idea how I missed this video but it's taken me from unsure about what & why to clearly understanding the reasons & the process.

Very clever Rob. Thanks for the tips.

Now it sinks in to what you were telling me when I was in class.👍😀
You have to hear it numerous times before the light comes on!
@@RobCosmanWoodworking This is so true when one begins a new journey. Well, the light did not just flicker, it on👍😂😎
Great video Rob- will certainly help as I practice. Thanks for all you do to support woodworkers and through PHP!

I thought that too
Yup
Apart from that, i love this method. All kudos to Rob and his team.
Great catch....Its easyto do. Sorry about that
Well, I can’t criticize anything here since I do something like that on every project. Great video and even greater community resource we have in Rob.

You can also use a marking gauge to pick up the thickness of your saw and then use the gauge like we use the shawn shim
Excellent explanation - thanks!
I just tried this and it works great.
Thanks for the feedback. donorbox.org/the-purple-heart-project
I love the Shawn shim
So do we
Thanks Rob, makes perfect sense.
I hope it helps. donorbox.org/the-purple-heart-project

Tks
You leave less space for glue.
There is still plenty of space for the glue. Have donw Hundreds of these and then we stand on them to test them. the glue never fails.
Amazing. Thanks. However, you shun using a guide to hold the blade or chisel when sharpening because you can learn to do it without. But you promote using a Shaun shim and saw blade knife. How do you resolve that contradiction.
It's not a contradiction. He isn't using them as a guide while making the cuts, just for layout
No contradiction. He understands that getting dovetails from the saw (which is possible and the most efficient way to do them) is quite complicated if you're a beginner.

What are you talking about haha. Sharpening a blade is a lot different than using layout tools....

This isn't anything new Rob. A few years ago I remember you demonstrating the same thing.
What’s new is interchanging the offset from one side to the other. I used to teach to use either .024 or .025, but this allows for finer control.
@@RobCosmanWoodworking Yes, that's right. It was a while ago not sure when it was.
