Does anybody have any experiance with the Harbor Freight Blast Cabinet P# 93608? I bought one today to use on AK (& a 1919A4 )rebuilds as the one at work that I have used for years is full of extremely corrosive stuff ( blasting some parts made them rust as if I put them in battery acid[ it reallly screwed up an AMMS build as it is rusting thru Moly coat on the top cover and underfolder stock]). I figure that the small amount of ocassional cleaning that I need to do will be fine with this unit. The blast gun is marginal, but should work. I will be using ground glass and blasting sand as a media. This hobby is getting really expensive.
