As far as I know if you can pull down to 20"-29.92"Hg (mercury) go for as much vacuum you can get, ESPECIALLY if you are attempting to pull material that thick!!

1/8" & 1/4" thick is somewhere between the wall thickness of schedule 40 pipe! I hope you aren't expecting to see any details of your mold with that thick of stuff! Shocked
