Subject: [CAD_CAM_EDM_DRO] vacuum hold down




I'm thinking of adding vacuum hold down to my 4'x4' router. I would like
to use a shop vac as this is low budget operation! My current thought is to
place some small 1/4" or so thick strips of wood on top of my table. Level
these off with the router and than place a sheet of Polycarbonate over these
strips and drill the appropriate holes to hold down the work. Most of the
work I do is cut through stuff and I don't want to chew up my vacuum table
surface. Is there something that will let the vacuum through that I can
sacrafice? Or just replace the polycarbonate as needed? Or put on a piece
of sacraficial wood on top of the polycarbonate and drill hole through this
as well to get the vacuum where I need it?

Pretty new to this stuff! So any help is appreciated!
