Harold is right on, COMPRESSOR, BIG COMPRESSOR!, when I first got mine and
used it, I was in love, until I found my little compressor wouldn't keep
up. I got a two stage DeVilbiss and it does run a lot but I can keep
blasting. I since upgraded and refurbished a nicer commercial cabinet.

Nice job on the cabinet Marty, I always marvel at how you can take what appears
to be the worlds biggest POS and make it into something worth having.

FWIW, the compressor I now have I was able to buy because of somebody else's
purchase of a blast cabinet. Nicely done home built unit, 120 gallon tank,
smallish 2 stage pump(Champion??), and a REAL 3hp motor.
The seller claimed it wouldn't keep up with his blast cabinet.
The mistake the guy made was that he had the compressor that was rated for
900rpm running only about 300rpm, just barely above the unloader valve govoner
speed.
I re-pully'd the setup so the pump now runs at about 800rpm, keeps up with my
HF blast cabinet just fine especially if I don't try to run at 120psi.
The compressor is set to shut off at 120psi, recycles the 120gal tank from
90psi 3 times faster than my 2hp 20 gallon CH unit.
