This is a Duplicator like the big router duplicators just small with just a pointy stick for a follower and a cutting tool. When I get some wax and clay I will test it out. This is a work in progress, next step is to minimize the free play while preserving the print-in-place tool arm's non-binding free motion. see this link for a crude youtube video to demo the idea anyway: https://youtu.be/YBS8VwAwQBg
