Can anyone point me to easy-to-understand (i.e., non-technical)
information about tumble polishing steel? All the tumbling links on
Google are about lapidary and jewelry applications. I'd like to try it
on a knife blade or two. The price of wet & dry sandpaper has gone
through the roof and I've just about run out of elbow grease to go with
I remember building my own rock tumbler when I was a boy. Used it for
several years before I discovered girls. So I know a little about it.
But I've never tried it on steel or other metal.
I have lots of questions. What media do I use? Can I expect
high-quality results with a shop-built small batch machine.? Will
tumbling destroy crisp lines on a knife blade (I'm aware that the edge
will have to be retouched)? Tumbling times? Anything else to be aware
Steel under consideration includes heat-treated carbon and stainless
steels, D-2, ATS-34, S30V, 5160, etc. Probably finished down to
220-grit or so before going into the tumbler.
Any info at all will be helpful in deciding whether or not I want to
