Thanks for posting! I see what you are saying about wearing down the edges but leaving most of the texture on the face. And the chipping I imagine is from the tumbling motion causing the chips to strike each other repeatedly. I am curious to see what @cpiaaq 's vibrating machine does.
 
I have rock tumbled super diamonds to get rid of the flashing and provide a bit of wear (using them in a vintage Faro game setup).

It worked great at polishing off any flashing and only wore the edges a little. I did it overnight for each barrel because they are hard plastic.

Me too.
For rocks vibrator tumblers are known to reduce impacts so may have fewer flea bites. For rotary tumblers media like these ceramic pieces are often used to reduce impacts.
Will be good to see result.

I sent @cpiaaq these ceramic beads as a media to try. I know he is busy for the holidays - I'm not trying to pressure him!. In addition, I would love to try just plain sand (like @cm1204) and something much softer (like rice or walnut shell). @cpiaaq also has some bigger ceramic media he can try as well. I think we have a good shot at dialing this in...and conclusively determining whether PART does or does not work.

What abrasive media did you use?

Just regular sand. I didn’t want to use the carbides, I was ok with a media that would wear as well as the chips. Not as severe as cutting carbides, I wanted to clean the edges and simulate some wear, but I didn’t want to grind them down.

I sold the diamonds but still have the faro equipment and the rock tumblers.
 
Yes they're here and ready to roll!

I suggest we start off with one of the broken ASM greek key mold chips. Maybe the top left, yellow piece? I call this one "someforcharity."

(If this works for you) place "someforcharity" in the tumbler with the ceramic media after work. Check on it and document condition after 2 hours. Then run it overnight if it seems to be proceeding well. That would give us a baseline to try different lengths of time and different media. What do folks think?
