I joined this forum to try to get some advice about choosing a compressor and accessories for an abrasive blaster. I'm hoping I can get an appropriate compressor to hook up with a blaster which I plan to use with bicarbonate soda. I have a piece of sculpture I made, but I used Flitz copper and brass spray cleaner, snd it left s coating of copper oxide on all he brass parts of the sculpture-green. I planned to have someone in the area soda blast the sculpture, but when I took it to a professional blaster, he said he wouldn't do it because it's fragile and he didn't want to damage it. I believe if it's blasted with bicarbonate of soda at a low psi, it can survive the process. I also thought if I'm going to spend money hiring someone else to do it, I may as well invest in the equipment because it's something I'll use more than once. I have experience using a blast cabinet to sand blast glass, stone, and wood, but I no longer have access to the equipment.
