I wonder about this dual pump thought too. Can you use old refrig pump for
the "cheap" vacuum pump? Lots of epoxy gluers do so. Chuck
to set up so that the shop vac starts the process and then the pump takes
over to put a bit of presure on the part. Remember that you only get about
14psi clamping pressure with a good vacuum pump.
I use a Robinair pump for some non machining tasks (RTV evacuation) and am
pleased with it. Lot of bang for the buck.

real vacuum pump that can pull a relatively high vacuum, but the CFM is
low or is there another style of pump that would work better. Most of
the items I am expecting to clamp will be slightly to moderately air
permiable.

to set up so that the shop vac starts the process and then the pump takes
