Hi, Jim Bloomer, the former club president, has a paint pot that he and is wife have used to pressurize plastic resins to make turning blanks. Paint pots are available from Harbor Freight and can be adapted to either pressure for resins or vacuum for projects such as yours. Vacuum pumps are available to draw the air out of a project, and the ones for running vacuum chucks will draw 22-26" of vacuum. I no longer have my vacuum chuck but some members have them.
