Please remove splinters before emailing

If you do a bit of researching on the net you will see that you can make a
vac chucking system with very little cost. Use an old freezer compressor for
the vacuum and make a rotating joint with some sealed bearings - the ease of
the rotating joint manufacture depends on what kind of outboard spindle
arrangement you have.
I used an old 2 piston rather large refrigeration compressor but bought a
Oneway rotating joint. I made my own drum chucks out of ABS pipe connectors.
