I finally got my vacuum bag system set up (mucho thanks to joewoodworker.com). I've done some veneering, and now I'm thinking about making a vacuum clamp.
I had the thought that I could drill a hold through my solid maple bench top and thread an NTP male quick release onto the bottom. Then take a piece of MDF and drill a hole though it. Put some neoprene tape along the edges on both sides. Then whenever I want to vacuum clamp something, I'd blow out the hole to clear any dust/debris that might have collected, attached the vacuum pump, put the MDF over the hole, and the piece to be sanded/routed on top of the MDF. Then turn the pump on (the pump is 3cfm continuous duty rated).
Am I missing something? Ideally I'd have a foot switch to release the vacuum pressure, but as far as I can tell it should work. Thoughts?
