This rotary tumbler was chosen because it runs slow (at about 25 RPM) and gentle to avoid breaking a delicate load of about 200 drilled glass pendants. Due to a large time investment in melting, pre-shaping and drilling so many delicate pieces I erred to the side of caution and ran them slow with protective slurry thickener using a small 6 inch barrel.
To get a better hole finish the holes should be drilled before the coarse grind but this requires a bit of practice in knowing how far from the edge the hole should be drilled before serious SiC 60 shaping takes place. SiC 60 shapes them in about a week and barely breaks down the SiC 60 so it gets re-used. Or running an SiC 220 step between the SiC 60 and SiC 500 step but SiC 220 is fairly aggressive and removes quit a bit of material on glass. The SiC 500 step easily prepares the surface for the vibe after 10 days breakdown but does not round some of the hole shoulders enough.
Perhaps another alternative is to run some smaller roundish media to reach the 2mm hole shoulders since these pendants are flat and barely reach the hole shoulders.
I'm half asleep doing a early morning video so bear with me.

You act like you've done this before. It is an easy tumble for a lazy or busy person Dave. 6 pounds of sawn glass. A benefit of glass is that it is soft and saws easily to nice tumble shapes. 1/2 cup SiC 60 for 7 days. 1 clean out. rotary. Inspection not needed. 1/4 cup SiC 500 for 10 days. 1 clean out. rotary. Inspection not needed.(or 3 days in the vibe with 2 tablespoons SiC 500) 1 tablespoon AO 220 for 5 days. 1 clean out. vibe. Check a sample and add water daily. Optional super polish - 1 tablespoon AO 14,000 for 18 hours. vibe. Today starts the 4 day Scott's Antique market. It is the largest antique/vintage sale in the SE US. I plan on going for the purpose of finding damaged or under priced jade carvings to reduce to tumbles.

Love your refining the tumbles of glass. But, Reducing vintage jade carving to tumbles will cause MsAli and me to cringe. Please do not destroy vintage jade carvings. Those are treasures. Something that can never be replaced. Understand that you are running a business, but Ali and I have told you many times in the past to not destroy valuable pieces. Please, Please, Please do not do this. Once something is gone, it is gone forever. The more people destroy historical pieces the fewer there are available. This causes huge price increases in the remaining pieces. Some would care a less, as they do not appreciate history and the artistry of these pieces. Some cry, like Ali and me. Reaching out to not destroy a piece of history.

Reaching out to not destroy a piece of history. I will refrain. Thanks for the sense of conscience. You are right, history is being destroyed regardless of the condition of the artifact fernwood. Me and friend shopped giant Scott Market yesterday. Probably questioned a dozen Asian dealers. They were offended at the question regarding cheap jade. Looks like British Columbian jade is the source but it sure is expensive. We did find some fine serpentine carvings but serpentine can be had cheap on EBAY.

He melted the glass into bricks, sawed the bricks into slabs, trimmed the slabs into multiple pendent sized pieces, drilled holes in them, then is tumble polishing them. IF you ask nicely, he may break down and sell a few to you.

I certainly will, but after I get to 100 postings. Don't want to break rules or anything.

avenueiarts I believe the 100 post rule is for posting stuff for sale on the forum. There is no post restriction on buying things. Go ahead and pm jamesp.
