So anyone made a vacuum lifter before? Venturi vacuum pumps are cheap on McMaster Carr so I figured why the hell not try. Trouble I'm having is figuring out what seal to use on the flat plate vacuum pad. I may start out with foam EPDM unless someone else can offer some advice. Two 18x14 vacuum pads can theoretically lift 5,000lbs at a vacuum of 26" Hg(with no safety factor). Thanks
Edit: Foam I might try. - Amazon.com: Foam Weather Stripping, Adhesive Foam Tape Sound Proof Insulation Closed Cell Foam Seal 1 Inch Wide X 3/4 Inch Thick X 13 Feet Long (1in 3/4in): Home Improvement
