re: Vacuum Clamping

This is the jig, with temporary weather strip tape, just to test the concept.

Jig with a cut piece in place.

Cut piece, jig and vacuum pump.

I bought a new roll of weather strip tape and redid the jig. It holds better, with a greater vacuum “footprint.” I really need to upgrade my pattern bit, though. The two-cutter, straight edge bit, works okay on pine, but I want to do Oak, Walnut and other hardwoods.
