« on: April 05, 2017, 07:07:53 AM »
i've been thinking bout making a contour jig to rest on my platen
so i can shape those nice reveals i see on all your knives.
the deal is getting the right profile and the ight wood to use for it.
lately i've been going back anf forth from the 2x72 to the 1x42,
if i could make a couple of these in differnt shapes itcould make things look better.

I've never used a jig, so the only advice I can give is that you probably don't want to use wood.  When you cool your work it will soak up water and change things.

Hope this helps.

I used a wooden block for a while and, like Crash said, wood is not ideal.

Here is what I use now. It was cheap and easy to make, bevel angle is infinitely adjustable, aluminum acts as a heat sink and helps keep blade cool.

Started with a 8" long piece of 3"x3" angle aluminum (1/4" thick). Drilled and tapped a hole in the center of the horizontal side. The thumb screw allows bevel angle to be adjusted, lock nut or jam nut keeps it in place.

Cut 1.5" off the vertical side and drilled a hole in the center for a piece of pin stock
