Vacuum hold down fixture for cnc router.

Well, Peter Sanders, If just taping it would have done the job, I wouldn't need a vacuum fixture. 5 minjutes into the video when I turn on the shop vac. look closely and you can see the plastic move down about 1/8th of an inch, holding it solidly against the fixture. Taping around the frame has nothing to do with holding the plastic down directly, as the reason is to make a seal, so the there will be no leakage of air, so that the vacuum will hold the plastic down. I suggest you critics out there, try your design first, before you knock someone's design. There can be no movement up and down when cutting allowing the blade to exit the plastic without lifting it, as the blade will try to lift the plastic if not held down, and also the vacuum will keep it from racking from side to side, so obviously you haven't tried to cut thin plastic with great accuracy, so your expectations are wrong.
