I too am looking to buy a bead blast cabinet and a compressor. I have a 220 volt, 30 amp circuit for the compressor. Suggestions? I assume the blast cabinet can run off my 20 amp plugs in the shop. Also, should I put the blast cabinet in my shop, or outside? BTW, I am thinking of a really long blast cabinet that will hold bumpers and such..... This will complete my dream shop!
