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.
Works perfectly just as Rob demonstrates in several videos! Really appreciate that I no longer have to balance my marking gauge on the saw teeth and HOPE that I set it accurately. If you already use Rob's 'new' dovetail method then this is the last piece of gear you need to cut consistently accurate dovetails. The ShawnShim is very well made and comes with a great little bag to keep it from getting beat up.
Looks good with enough registration but haven’t used it yet, love that it has 4 different kerf sizes and feels good in the hand
Nicely done great design
This simple gauge make the Cosman Dovetail method easy to do. Get one and see the ease of gauging and marking your dovetails will be.
Very easy to use
