Hello,

I'm in the progress of making my own vacuum table.
The grid will be milled into a sheet phenolic.

At the moment i'm struggling with 2 points:

1) which gasket seal to choose:

-Round / rectangle or d shaped.

If i use a round seal (easiest to find) would i neet to mill the groove with a ballnose bit? so the gasket matches the groove? Or can i go with a straight endmill?

I'm building an universal table setup with 6 different zones. The contour of the zone i would seal off with the gasket.

2) Would i mill the grid with the same endmill/ballnose bit (5 a 6mm wide) Or would i use a wider 12mm endmill for the internal grid so i have a better air displacement for the vacuum.

Input would be appreciated!
