Tell me a little more about your vacuum table.
MDF?
Plastic with channels and gaskets?
Type of gaskets?

We made a nice holding fixture that was around 2'x3' that we held down electronic component boards,that we trimmed with a lead trimmer after it ran through a wave solder machine.We used a large shop vac with a foot switch and it worked great.

Here's what I use for a similar setup.

It has a pretty high volume, and still pulls a decent vacuum.
The high volume helps you to make the initial seal, and the good vacuum makes for good holding power. You can get pumps that will have stronger vacuum, but without any volume it can be hard to get the initial seal.
One other thing that is about as important as anything for me is that this pump is oil free. Any pump that uses oil to form the seal inside will blow a mist of oil out into the air.
I have 3 of these, and they often run 6 hours a day, or more. They are easily rebuilt, but I haven't had the need to do so. My oldest one is probably 3 years old if I had to guess.

Royce-
I checked out the pump you mentioned and I see that those vac pumps are mainly used as compressors (makes sense!). I have a small oil less compressor that I'm using now. I wonder how much vacuum it produces? That would be really handy if I could use it to hold down my inlay materials too.
Thanks for the tip. I'll dig out a vacuum gauge and go from there.

Robin,
It may work, but I'm not really sure.
I would think that the volume would be suspect. The volume is really critical. It's very frustrating to have the pump running and can't get your part to close fully enough to make a seal.

Thanks Royce. I understand what you're saying. I'll try it soon and report.
I'll guess that using my compressor will yield high volume/ relatively low vacuum similar to the one you mentioned.
I was concerned that throttling the intake might cause overheating due to low air flow but that seems to be the setup on the one you mentioned : it's designed for use as a compressor too.
I'll give it a shot. Once again, thanks for the advice. If all else fails, I can get the one you mentioned.
