Sandblaster/cabinet build your own.

My dad made one of the ones in the old steel drums on its side. Worked OK, but we sold it and are now in the process of using an old washing machine to make another. Just big enough to get a wheel in and if mounted at 45 degrees then the sand will fall into one edge for collecting, if that makes sense. The old bearing and bracket is going to be used as a 'spinning' hanger for spraying parts inside an old tumble drier. Good use for old white goods.
His old 'gun' was a ceramic part of a spark plug pushed onto the end of an old air gun with an attached pipe for the sand feed. But I have treated him to a proper SIP blasting gun.

I'm lucky enough to have access to several industrial sand/grit/glass bead blasters in work, however I was wondering about the possibility of using an old top loading washing machine or tumble drier, filled with ball bearings or ceramic beads - as a polishing machine. Any thoughts?
