But you are cheating the merchants out of numerous blade sales. And saving my lungs. I'm sure they appreciate that. Living customers are the best!

Two big rocks that did not do well. Bloodstone. Can not seem to escape bruises. It has been rerun 3 times and tried all the tricks. Last run the slurry was too thick and the media got concreted serving as an anvil and beat up the surface terribly. Going to set it aside for a while and rethink. the best bloodstone run, but still had scattered bruises Rhyolite did fine in rotary. My vibe does not polish rhyolite well. Even small pieces. Matte finish and tickled with it. (my) Vibrasonic Vibe does micro bruises on even small rhyolite

Pulled this wood out of vibe after 12 hours in Borax and AO 80 this morn. 100% success. Can tell after the 12 hours if it will polish. Will do AO 500 borax and AO 14,000 borax.

@shotgunner captbobThis chipping action is another benefit with the cups. By putting the rock up against the edge of the diamond Segments(corner) end tips and edges can be basically hammered off. Fast shaping with basically impact action. Not so needed for a pre-shaped sphere shape but very effective for tumbles that need to be rough shaped. From super grinder: "Apparently the gap between the blades causes the rock being ground to “chip.” When you examine the “mud” produced by the grinder, you find that nearly half of it is very small chips that are likely produced by the “gaps.” "

I would have sworn that the bloodstone would have been your finest out of all these you have run. odd.....
I would love to make one of your king kong grinders, but I don't know where I would use it. Don't have the acreage to use where it wouldn't bother the neighbors, or the ground chips, dust etc would be away from where the dogs could get. Even the ganged saw blade machine (super grinder) will be problematic as far as coming up with where to use.

What is the last grit that this went through? Looks like a 60/90, or coarser, finish at best. Send it to me, I'll fix it for ya!

Need to find out jamesp 's rates for king kong grinding rocks by the flat rate box load! Oh no. Maybe with a sweat shop full imported young ladies doing the grinding. Grinding a means to an end. James ground enough metal to do a Golden Gate bridge. Even with super grinder. Monotonous. Totally blown away by he bloodstone. Makes no sense. I rubbed a tumbled absolute hard wet polished pet palm on it and the bloodstone scratched the palm. Always got a quick polish tumbling hard slow-to-coarse grind bloodstone, telling it is hard. I chose it for the first big rock figuring it was the hardest in the arsenal. The photo above with the deep damage was damaged because the slurry got to thick and the media pasted on the walls of the barrel. Which beat the bloodstone. Have had that happen but a couple of times since using clay. Still dialing in clay/water/rock mix for these small barrels. The best that bloodstone looked was in the old 15 pound barrel, before the 6 pounders were used. Clay/water/rock recipe dialed in on those. The 2nd time I ran it with 3/16" garnets as media. Ran 4 days and the SiC 30 would NOT break down. Gave up on that. Catch your drift on the dust/noise factor. Doing my grinding way over in the greenhouse with the big exhaust fan on. Grinding a cold weather pastime due to heat in greenhouse. Wife hears me from house and knows I am screwing off. Coral, McMinnville wood and lace all went through the whole process without a bit of problems.

Will slow down soon and run 2 or 3 barrels w/big rock in each. Move them to slower 1/8 HP tumbler. Too much work doing 5 changing/adding grit once or twice a day.

rockpickerforever what is this egg drop soup agate ? Don't be commenting on my black creation It is cool! Oh, you want a name? IDK!!! All I know is I did not personally collect it. It is either swapmeetium, estatesaleite, or freerocksaleite. Or, it coulda been in a 5 gal bucket of rough for tumbles, purchased inexpensively at one of the SD club's silent auctions over the years. If I was a betting person, I would say most likely is the freerocksaleite. I believe whatever it is, it was found in California.
Perhaps Mel knows what it is? I think we talked about it before, and he may have said Roostertail Agate? Or maybe that was another one...
That wood is sure shiny! All your tumbles are looking good, James!
(Okay, no comments on the black creations, lol.)

Rooster tail it is according to google images rockpickerforever. It is very flashy, would take 100 pounds. It is another diamond buster. Very hard rock. Way harder than coral. The real hard rocks bounce on the diamond wheel and cut way slow. The bouncing causes little surface fractures on edges, a problem. Better to run the diamond wheel slow on theses really hard rocks. Sumatra Flame exact same way. You can tell in a hurry how completely different theses rocks are in the agate category. About always ground Rio's and coral. Rio's variable but most are moss and just not as hard as these two customers. Recently doing these rocks you have given me and some rocks traded with Roy. Roy gave me a chunk of crazy lace too and it is very hard. The wood above was not near as hard. Yet it polished fine. More important, it rotary tumbled fine. I added a step on the wood, AO 80-AO 500 and then AO 14,000. And ran them each longer. But they have to be rotary tumbled well. If they are not baby but smooth out of the rotary do not bother putting them in the vibe. 5 barrels at mostly 55 RPM been keeping me hopping. But production of shaped tumbles fastest I have ever done by long shot. It is that big rock grinding them so fast, no doubt. I would suggest rooster tail to tumblers. what a beautiful stone. One of those Garage Rocker quality macros of rooster tail from images

2 pound tumbled rock with wet shine. Nice. I love this idea. Chuck Give it a go Chuck. Do a batch of 1-1.5 inch agates with a +/- 1.5 pound hard agate, and best in your 12 pound Lortone. Best to use all hard stuff, smalls and large. I am not sure about finishing steps in the rotary. Maybe fill the barrel fuller or add ceramics ?? The success of that polish is that fat mouth Viking. Try rooster tail agate too. Maybe Ebay has it.

jamesp, did I ever tell you I miss Fred? I mean, I really like the knapped knife that orrum made and sent to you, but as your avatar, I think I could relate to the green frog better. And one more time, did you name the puppy??
