I end up with rusty steel no matter what I do. On some projects, I use a lot of short (2-6") of rod, tube, FB, etc.
I would like to make a tumbler out of some wheels, a gear reduction motor, (which show up cheap a lot at a pawn shop I frequent), and use five gallon buckets with tops.
Is this a good setup? I don't want to buy a big expensive tumbler, and good enough is good enough.
What do you use in them? Ball bearings? Playbox sand? Another type of sand?
Help appreciated.
