Never thought to use the Rob Cosman shim method for a box joint even though I've been using it for dovetailing for a few years. Blindingly obvious now you've pointed it out of course! Thanks for another helpful tutorial.
Thank you Brian. One thing I'm struggling with is the white balance on my Google pixel 8 Pro phone. Not sure if I need different lights. Glad your enjoying the videos though 😊
Well it did not shock me but your technique is thorough and well taught and I enjoy your videos. I made my own ShawnShim on a 3d printer. I thought $42 was a bit steep for this.
Haha brilliant, I can't believe your not shocked 😅 I did people could do that but didn't want to encourage it 😅 it's a well engineered little bit of kit though. Thanks for watching.
Deceptively simple, I suspect it's a good idea to write a clear set of bullet points and have them on the bench in front of me. Very easy to screw up! Very nice results though
Watching your video, I wonder how close you would get by using the saw blade in place of the Shawn Shim. If you held the saw blade against the side of the piece and displaced the other piece to line up with the edge of the saw, would it work. Of course there will be a small discrepancy due to the kerf being a little wider than the saw blade, but I wonder if the variance would be small enough for the technique still to work. And yes, what I should really do it get to the workshop and try myself :)
Hi Rob I did try this method prior to receiving the shim and it was not successful for me however people use the wheel marking gauge to the same effect and Rob covers that in his video. 😊
@@karlpopewoodcraftI've now watched the original videos - it is excellent. Plan B: Get a piece of perspex (reasonably thick - about the thickness of a board you want to dovetail) and cut a vertical slot near one side with your dovetail saw, making sure the slot is parallel to the side. Then make a cut in the side level with the bottom of the slot such that you remove a rectangular corner from the corner of the perspex. Then with some CA glue the piece that you've cut out back into the corner of main perspex piece. You'll find the small piece will be offset by the width of the saw kerf. There will now be a one kerf thick step in the side of the perpex piece. Use that the way you'd use the Shawn Shim. I don't think you'll need to be absolutely perfect on the main cut because any discrepancy will tend to cancel out as long as you keep the piece you cut out in the same orientation when you glue it back in. You could even use a bit of wood - the advantage with the perpex is that it won't change dimensions over time. Also you should be able to cut perspex without it damaging the saw - which might be an issue with some other materials. If nothing else it would be a way to test out the technique before you feel the need to invest in the Shawn Shim.

Your welcome Mike, I think most people do their box joints on the table saw! I like the process though.
So essential this widens the pins on both of their sides by the exact width of the saw blade?
Correct.
Your a good teacher Karl, modern tech leads us to online advice, and I watch your teachings with great interest
Thank you 😊
Another superb joinery tutorial. I’ll have to give these a go. Keep up the great work.
Thank you 😊
Another great video look forward to watching them each week. Nice talking to you at the Newark woodwork show keep up the good work
Cheers Andrew, you to nice to meet you today.
Love watching a master of his trade at work. 👍
Thank you Jim, Learning everyday mate.
Hi Karl, as always brilliant technique enjoy watching what your doing, Take care mate
Thanks Shaun 😀
Good job Karl, I thought the camera work was mint. Excellent shots of the work etc. Keep up the good work. All the best.

Clever idea to use shim to box joint, good video
Thank you 😊
Another great lesson Karl. These videos are great
Thanks mate, that's really appreciated.

Definitely easily to mess up on your first few attempts don't ask me how I know. But once you get your head around it you'll be grand.

@@karlpopewoodcraftLooks like I'm going to have to have a good look at the Rob Cosman video.

No offense, but I just don't get it...
If you are going to do all the work of hand-cutting the joints,
why not just cut dovetails?
Simply because some people like the look of the box joint and to demonstrate how the Shawn shim helps make it easier.
