Hi all,

I am wanting to make a vacuum table to hold down cardboard to be cut with a drag knife on my cnc router.

I'm not sure whether to make a grid system with gasket seal or a table with open holes that the cardboard lies over top of and block off any holes that are uncovered.

I have a small becker rotary vane pump that I'm hoping will do the job. The model is VT 4.4 link is here http://www.becker-international.com/...?id=0000012715

I need the table to be about 1m x 1.5m in size

Any help much appreciated.
