Shop vacs are low pressure, high flow. Really not even close to ideal for a vacuum table.

We got a surplus vacuum pump from a mentor we've been using (looks like a large old KOP thomas compressor) for a small table. I know do do anything of meaningful size you need something decent and beefy.

I'd try to find someone local in industry with knowledge in routers (cabinet shops often have some HUGE ones) to point you in the right direction, it can be a tough thing to google if you don't already know what you're looking for.

They'll also give you great tips all around on how to run the machine, what to fixture with, etc...
