Quiet/Silent Compressor

[Michael Kellough]

These are questions best asked at a CNC forum but as I understand it if you cut a hole through the work over an air clamp (Venturi or vacuum) you’ll not only loose the clamping action but the work will lift up some (decompression of the gasket).

Also going back to an earlier Michael statement, MDF will not work on a vac system, it's too porous. I've fixed that by putting a couple of coats of sanding sealer on both surfaces of the MDF.

If you cut through the wooden substrate and if that's over a vacuum path, you will lose your hold down clamping.

I am certainly late to this discussion, but a Venturi pump would be miserable to use.  As already suggested a vacuum pump may be able to do this for you.  The smaller the pump you go the smarter you will need to be as to how many suction points, etc.  Also if you want to set up a large grid you might want to look at check valves (balls) for the suction points to allow unneeded points to not be wasting the limited suction you have.  With a small system you’re approaching the effect of the old Christmas tree lights where if one went out they all went out.

Depending on the strength of your vacuum pump and qaulity of mdf it usually works.  The festool pump will hold two superior grade mdf panels without a problem but a third does not work as the mdf starts leaking more air then the pump can remove
