This brought back thoughts of a time when I was a kid (a long time ago) when my father bought a sears compressor and a sandblast kit. We had a rusted round deck table, that he wanted to sandblast the rust off. Shoveling the beach sand into the hopper was easy, waiting for the compressor to pump up to took forever, after a week of blasting, had almost a quarter of the table top done. He bought a couple of wire wheels for a drill motor to finish the top in a half hour. This was over 45 years ago, but I don't think that things have changed much. I now have a 5 hp 230v compressor outside the shop, dual stage, with a 200 gallon tank, I think that it is in the 18-24 CFM range at 120 Psi, and I think that it might not keep up with a sandblaster.
