I worked in a shop with a skat-blast cabinet(nice$$$) and the shop compressor couldn't keep up. Do you know the specs on your compressor? (i.e. 10cfm @ 90psi)We had to run the big engine driven trailer style one to be productive. So I think for small parts, you would be OK with your compressor. But trying to do a bunch of big stuff, you'll get pretty frustrated.
