Operating a sand blaster (or any high usage air tool) needs to be figured at CFM (cubic feet per minute) and on a large cabinet to gain the best usage probably 15CFM and above will be needed. A small 20 gal tank will drive a gun, it just wont drive it very long. A 60 gallon tank with a 2 stage compressor should put out something in the 15-20CF range.
HF's large blast cabinet is another one of their hidden treasures - its well made, its cheap, and it just works well for a cost of around $200 and you can probably wiggle in one of those 20% off thingies. I have their cabinet with a 60gal tank and a compressor driving 19CFM and I can blast for long periods - the compressor is running constantly, but im getting a good blast of air
I agree, I have a 80 gallon tank and a large 15t series Ingersoll compressor, along with the blast cabinet they work great. Tim

Why everybody thinks they need a two stage compressor I don`t know. A single stage two piston will give twice as much air as a two stage. It will only go to one hundred and fifty pounds but most shops do not need more than that.
My 2 stage runs 15 cfm at 175 psi, with a 1745 rpm motor, quiet enough to have a conversation when its running. It pays to have a good compressor. The single stage's cant keep up. Tim
