Hi,

We are looking at getting a CNC (8' x 4') router, we are going to be cutting 9mm birch panels.
I am just designing a Vacuum Table system to allow us to have 6+ vacuum sections on the bed, i found a great tutorial from a US source.

The question i have .. if using 50mm piping to create the vac distribution system under the table with cut off valves for each section. What grade of piping and valves should i be looking at?

Many Thanks!
James
