I need to vacuum degass some silicone rubber before shooting it into a mold, I've seen some canisters (looks like I could make my own pretty easy out of a paint pot or other such device) and the pumps...big money.
Anyone know of a way to do it cheap? I have a big air compressor, seems like there would be a way to turn that thing into a sucker? Guess there is always the shop vac
