Thanks, I found them. I don’t have the dog holes in my wasteboard, but, with the CNC, it would be easy to add the holes. After trying a number of different clamps, I’ve pretty much standardized on just “screwing” the piece to a piece of MDF attached to the wastedboard. The holes con be filled and sanded along with any groves made during piece cutout… When making a number of the same carves, like coasters, I use screw inserts instead of just wood screws to hold the piece. Then, it’s easy and repeatable to remove and replace items during different toolpath operations.
I also do 3D printing so it might be easy enough to reverse engineer the Kreg design.
