My first attempt at knife scales involved cnc, router and drilling. I have attempted and succeeded at using plywood as a fixture plate so I can flip the scales and get awesome cuts!
Fixture plate. First with pen, then I drillled holes and hot glued 2-56 nuts.
Screwed down the sheet of micarta and cut the screw holes with a 1/16th bit from v1. Thanks Ryan. These holes were enlarged with a #44 drill bit to just the right size for the #2 screw.
Change bit to 1/8th in end mill. Cut the profile , then the pockets.
Finally I dipped the scales over and chamfered with a 90 degree v bit. One scales suffered from an unknown error. The worked great. I am calling this a great proof of principle.
I don’t quite understand your rig for the double sided. But it sounds like you have some kind of base that allows you to flip and mill.
For my scales I used openscad to model parametrically and then Kiri:moto with register pins to allow for flipping. I think I used tooth pics for pins IIRC?
O set my origin at the x and y home. 0,0. I then drilled then cnc the holes for the screws and pivot in the fixture board. Open those holes up to just fit the appropriate size nuts. Hot glue those in. Attach a sheet of material and run the same program. Screw the sheet down through the holes and run your program. Because the right and left scales are mirrors of each other they can screw down to the other side when flipped over. Keep the end stop home as 0,0
