Gary,
You're way underpowered to be attempting to blast frame and panel parts.
You'll need a compressor closer to 10 hp with 12-15 scfm@90psi. The unit you
have could drive a small blast cabinet, but a piece of 100 sq cm surface
area will take several minutes (you'll have to stop and wait while the
compressor recharges, then shoot again; its quite frustrating). A big
compressor is a valuable tool, but these things are really heavy, loud,
consume a lot of space and power, and are generally not mobile. A pleasant
and dust-free alternative is to find a local media blaster guy for your big
stuff, and stick to doing small pieces in a cabinet.
