Shawn Shim Dovetail Offset Tool
One of the most difficult tasks in hand cutting dovetails is accurately transferring the tails and precisely sawing the pins. Rob's improved method of transferring tails to the pin board by offsetting the tailboard by the thickness of the saw kerf takes all the guess work out of where to saw.
Offsetting by the exact thickness can be challenging, but the Shawn Shim helps improve your offset accuracy. The brainchild of one of our Purple Heart Project alumni, we named the shim in honor of him.
Precisely milled to the four most common saw kerf thickness, the Sean Shim allows you to precisely offset the tailboard.
- CNC milled from solid brass.
- 3/4 inch x 3/4 inch wide. 1-1/2 inches tall.
- Four offset sides: .023, .024, .025, .026 of an inch thickness.
- Offset amount engraved on each end of the shim.
- Weight: 100 grams
- Made in Canada.
I had already created a pseudo-Shawn Shim using MDF, precisely because it was easier than balancing my marking gauge on the edge of the boards. But the real thing is MUCH nicer and inspires more confidence. I especially like the fact that you can customize the fit of your dovetails by using a side that is one or two thousandths "off" one way or the other. Maybe my technique needs work – well, certainly – but until now my dovetails have all been just a little too tight for comfort. I suspect my MDF shim wasn't as accurate as it could have been. The brass Shawn Shim has addressed this problem for me. It is a great example of someone just taking the time to think about "how can we make this thing even more useful?" As with every tool I have bought from you folks: well done!
Works as its supposed to work. Love it!
Haven’t used it yet, but very well made and readable.
Can't wait to try it out
The lights were turned up and the cap was on tight. great tool simplifies the process of cutting dovetails.
