Since my new bench grinder is so tall, I was going to have to build risers for it anyway...so I decided to take a crack at designing and 3D printing the whole jig in one piece. That would result in fewer points of error getting it properly positioned and square to the stones. Since I designed it in Fusion 360, I was able to model the exact spacing of the jigs relative to the stones, and use that to create my mounting holes and some recesses to hold the jigs. I exported SVG files from F360 to my Shaper Origin for the top and bottom of the mounting board. Then I cut my bottom countersinks/through holes for T-Bolts and the recesses for the jigs. They have a nice friction fit into the recesses and aren't able to move around or go out of square. Now it's time to fire the rig up and reshape some tools!
