With every CNC router, strong and secure workholding is critical for a successful job. At Sienci Labs we’ve tried many designs, and created these universal clamps to be easy to use and make on any CNC router.
The goal for these designs is to allow folks to make their own clamps using cheap and easily available materials. For these projects, you’ll need plywood, ¼-20 fully threaded hex bolts of various lengths, ¼" washers, and ¼-20 threaded inserts. Depending on the T-track you have, you may need T-bolts that fit as well, but if you’re looking for a T-track for the first time, I’d recommend finding some that have a profile that fit ¼" hex bolt heads instead.
