Before we were talking about the media blasting equipment problem that our member was having and here is where we picked up.
The 70 grit aluminum oxide does work in my siphon cabinet, it just takes forever to clean a painted or heavily rusted part up. So, I’ve been using a wire brush on a bench grinder and a wire brush on a 10,000 rpm handheld to get as much off before I take over to the cabinet for final cleanup. My expectation was that I could just do everything in the cabinet in a timely fashion. Am I being unrealistic?
I’ve been advised by others that I may want to consider using 50-80 coal slag instead in my cabinet. Do you have any thoughts on that?
My Answer: If you use the aluminum oxide in the pressure pot it will work better than the syphon unit but it still might take some time for the paint to come off. The professionals usually use huge sandblasters that use up a lot of abrasive and air which of course works better. These also have wider sandblaster nozzle tips.
I think coal slag would be a good choice also. I hear a lot of people recommending that too.
