I don't know who shared this chart first but it has been helpful to me so i'll add it in here:
Recommended Polishes For Lapidary Materials from Benjamin E. Schmidt [Ed. note: I found this list of recommended polishes in some old files recently. It was compiled by Ben Schmidt at least 10 years ago and given to me for my own use. Ben was an excellent cutter and so I thought I would share the list with you.]

Wow, that is a killer reference. Perhaps you should transfer it to tips. Well done.

A good reference, but there's no mention of Titanium Dioxide, or Aluminum Oxide

Well almost- I was checking the barrel and the lid was flexing- dang thing was about as thick as a sheet of paper- so as a temp fix I cut and acrylic disk and used some teflon tape to get a good seal! was real cool when I started it up in 120/220 I just had to take a pic a peak into the world of tumbling!

Stefan, I sure wish that the whole barrel on these was clear, I wouldn't have to be opening it up all the time!!

Just curious if there was a reason to revive a 17 year old dead thread with no new content and only quoting the OP?

Just curious if there was a reason to revive a 17 year old dead thread with no new content and only quoting the OP? Dead Thread? Early RTH'ers had great information that is right on for today and should not be lost. If that is not true why should any of us bother sharing a single word?

Thank you 1dave. I wonder if Mr. B. Schmidt was suggesting these abrasives for tumbling or for wheels and buffing pads. Abrading with a tumbler -can- dance to a different drummer than when used with buffing pads and wheels.

Yeah - the cutters that came before us used methods and materials no one who learned solely on modern equipment would ever have a clue about.
These are recommendations for lapidary polishes, not geared toward tumbling.
There are other tables listing lap/compound combinations for various minerals. Canvas, felt, different types and grades of leather, etc, all work a little differently - just like polishing compounds do. With the right combo there are very few "problem" stones.

I've seen the list before when I was looking around about my expando drum belts and bookmarked it to come back to. Thanks for bringing it up! I use some of the older techniques in my lapidary setup. Not a whole lot of diamond wheels in my setup.

A blast from the past to be sure. And there is a photo of my clear lidded Model T!
