Rob Cosman's Dovetail Trainer
The most common problems students have when learning to cut dovetails is how to make a plumb (straight up and down) cut on the pins and angled cuts on the tails. The secret is to develop the muscle memory so you can "feel" these cuts. I developed my Dovetail Trainer to help students quickly and accurately develop this "feel" and build lasting muscle memory.
Attaching my Dovetail Trainer to the end of your dovetail saw gives you a visual reference telling you if you are holding your saw correctly.
In just a couple days of practice you will be able to remove the trainer and make those critical cuts from "muscle memory".
Made from strong “Delrin”, its light weight and won’t throw off your sawing.
It adjusts quickly and easily for sawing “plumb”, 1:6 angle (9.5 degrees) left and 1:6 angle (9.5 degrees) right.
Fits any saw with up to a 1/4 inch thick back and holds in place with a non-marring nylon set screw.
Has highly visible green oil filled vial for a stable bubble.
Works left or right handed.
Really Good Trainer
So far so good with this trainer. It helps me focus, and it also triggers essential details from the workshops, about saw placement, technique, grip, stance, all the things that attribute to plum cuts. A must have for the hobbyist wood worker that wants to keep out bad habits.
Perfect for honing precision dovetail cuts without a guide block
Another great Cosman Training Aid
Having trouble getting the right freehand dovetail angle? This works !
Disappointed - poor machining, quality control..
I had to disassemble it and lubricate to get it to move/rotate at all. Hard to see gradations. Overpriced and not a value
Long time wood worker, re learning the hand tool side again, this gives you another tool to help in getting that feel for the angles and gives you something else to help create those perfect dovetails
