Added 6 tablespoons of AO 24 to 7 pounds of rock in a rotary after coarse SiC step. Used clay to float the large particles. Slow 30 RPM. AO 24 after 10 days in rotary completely disintegrated it. Did very careful clean out and found no left over AO 24 particles. Rocks with a sheen. Moved to AO 14,000 in vibe with Borax 2PM Friday for 18-20 hours. Likely to polish. Probably should have let it roll 14 days. Liking the AO 80 better. No need for slurry thickener using AO 80. No logic in using the overly big 24 grit, except to find out if 10 days in a rotary would break it down completely. Will post results from vibe about lunch tomorrow. AO 24, lines on paper = 1/4 inch. Big grit, cannot get lost in clean out:

Looks like the trees are not coming down. Last ice storm Feb 2013 www.flickr.com/photos/67205364@N06/sets/72157675039543344

Really surprised that broke down in 10 days and am interested to see the batch (am assuming there were some larger rocks mixed in?).
I've been looking at AO80 from Panadyne Abrasives, their bulk prices seem decent. Was thinking of ordering a 50 lb. bag of 46/70 SiC from Kingsley North but with shipping it's almost twice the price of 45 lb. of 80 grit so might go that way instead. Their ungraded mixes are about 50% more expensive than the graded which seems backward to me.
If I could get by with 80 SiC to 80 AO in the QT12 to get to a pre-polish and then polish in the vibe i could afford to roll some rocks.
BTW we have a foot of snow and a high of 7F here today but last week had about an hour of freezing rain, and i think i prefer the snow and cold to dealing with sheets of ice. Stay safe.

Kingsley should sell 30-45/70-80 for $88 plus $18 shipping. They have to ship it in a LFRB to get that price. Best to call them, their website is nebulous about the LFRB option. Hell yeah, I only ran AO 80 trick twice and then this crazy AO 24 run to settle my mind. I can see the AO 24 doing a careful clean out. I know it was crunched to nothing, and laid a sheen down in the process. Without any monster rocks to crunch it. Or extreme speeds. The AO 80 is the trick. And it will run without slurry thickener. Removes the worst SiC 30 scratches. Vibe or rotary. Available at Northern-Harbor Freight-sand blasting stores-some hardware stores. El cheapo if you catch a sale at Harbor or Northern. Ebay sellers do it in smaller quantities. I only use half a normal dose, so 10 pounds lasts a long time. Lost power, came on at 10AM, dang ice storm. Pine tree on my property snapped and pulled wires down. Looks catastrophic, ice will melt and bamboo will stand back up. Wood stove roaring, front door open at 22F.

And then he went out and sat in his deer stand. Worried about getting fined for hunting from a vehicle?

Gotta trudge over and check tumblers, power back on. Must go thru woods on ATV, all roads blocked by leaning bamboo. High winds, 22F, bad out there.

Hard to believe SiC 30 to AO 24 for 10 days in rotary to AO 14,000 for 12 hours in vibe. What is this rock rockpickerforever ? 1dave

I didn't expect such pure AO. That is sapphire crushed into grit. Wow!

How are your greenhouses heated? There is a burried 6 inch PVC pipe line that carries water from a high creek 2000 feet underground. That warms the water via ground heat. This water gravity feeds the water holding boxes in the houses by small drip tubes. Add the sun and they rarely freeze.

Min quantity I could find was 25 pounds. Apparently the rotary tumbler puts a hurting on it. Learning coarse AO. Does miracles Scott.

Might be a stupid question, but if you have a Vibe why not do the "normal" Way (1.fase in tumbler and the rest in Vibe) It seems like 10-14 Day + for the AO in tumbler is just adding more time before you finish the rocks. Do you get better results, is it cheaper or ?? Sorry but the stupid newbie dane just dont get it, but love the shine😃

1dave, is this a geologic term ? "My guess is Welded Ash Flow Tuff." Yes. There is Ash FALL Tuff and Ash FLOW Tuff. Like at Mt St Helen, Ash Flow tumbles along the ground for hundreds of miles mixing everything up at at around 1,000 oC. The middle layers can take months to cool while metallic crystals grow in moss and plume fashion. There is a lot of it in the western states where the most recent explosive volcanics took place.
