sallystrothers Posted February 23, 2011 Report Share Posted February 23, 2011 (edited) I'm curious if any others have produced their own vacuum chambers in the price range? I have made a chamber with a hand pump that will pull -20"hg and seems to pull all the gas from my liquid mold material. What are other people using for vacuum chambers/pumps?
