Alan ... send me a PM and I will give you my number to walk you through it. It really is pretty straight forward. You need a decent but not industrial quality air compressor, a shop vac and a relatively small blasting cabinet. Oh ... and media of course. The cabinet I have is about 18"x18"x24". The media goes in the bottom and is propelled by the compressed air. The shop vac sucks the dust and sediment out of the air so you can see clearly ... it is not necessary for small jobs. I use a medium grit glass bead at a pressure between 60 and 90 psi depending on the results I am looking for. The one thing to remember is to not mix stainless and carbon steel without completely cleaning out the cabinet and media as small carbon chips may imbed in the stainless finish and show up as tiny rust spots. Here's what you can expect ...
