Folks,
I have recently made myself a vacuum table for my next project for the flat panels, c/b and rudder construction.
Cost about $100. Just a sheet on melamine and aluminum frame from 2x2 angle. Vacuum film stuck to the frame with mastic. A self adhesive weather seal stuck to the lower surface from the local hardware store. Seals between the frame and the melamine.
Some line and pulleys to lift the frame up to he roof so I can work on the table.
So simple and it works a treat.

I can pull 22 inches of mercury on this table.

Regards,
Phill

I know that the voices in my head aint real,
but they have some pretty good ideas.
There is no such thing as a quick fix and I've never had free lunch!
