They are already nicely rounded. This would take 2 months at 30/60. They were sharp and hammer chipped before pre grind. Lavic jaspers-fine stuff Larry(Quartz) wood from Oregon(focus bad) Zephyr Hills Fl. coral Black Bay Fl. coral Suwanee River Fl. small corals Withlacoochee River Ga. bluish coral that was on Youtube chipping video Also Withlacoochee Also Withla Also Withla

if you add up how much time it takes each week to sort the rocks and re charge the barrels during 30/60 you are probably ahead of the game at 3 hours labor for hand grinding.

Chuck The tumbler is on a second power meter in the nursery. I rarely run anything in the winter except the tumblers. Base electrical charge is $20. Bill is $60 w/the 1/8 and 1/3 HP going and $50 for just the 1/3 HP. So $30 for electricity for the 4 barrel tumbler alone. Then recharge with 30/60 every 4-5 days is 5 cups six times a month. The grit kicks my tail. The grinding wheel cost $20 and does not want to wear out. Guessing 400 pounds of tumbles has been run on it. Grinding the rind off can cut the weight by half on the thick rinded coral. And i am sorry, but the labor is a problem. It takes me a good 2 hours easy to do the refresh and more if cherry picking. The pre grind takes a little longer than a 4 barrel refresh. Pre grind is the way to go hands down. It almost stops any need for cherry picking too. And everyone should remove those that are ready. I know Chuck does it. I will run these for another 4-5 day charge. So 10 days max. After 5 days i could not find a single bring mark from the 30 grit grinder... And closer to round/oval stones seem to grind very efficiently.

Thats the way to go for you warm weather folks. I'm thinking thats an outside chore and its 3 degrees here at the moment. I spend no less then 2 hours doing my grit changes and rock inspections every Saturday (for about 40 pounds of rock) so your estimate is right on.

I am well organized and in a dirty greenhouse and it still is a big job. And when that grit is worn i change it. If it is worn to 220 or 150 it ain't gonna round your rocks. Get a fresh charge of coarse in that thing. Even here my fingers are numb. I go about 30 minutes at a time and come in to thaw out. Sometimes i wait 10 days to allow my skin to grow back.LOL.

Nice show, like all the variety. Where does the Lavic jasper come from, read about it several times but never seen origin? That is nice mtl.

It ain't a horse race but you don't want it to be a tortoise race. That's looking really sweet!

Yellow Groove(aureasulcata) and i can't remember . It will not kill them. But the leaves will fall off and it will look bad. The roots are very hard to kill. salt or goats for several years

Nice showing James....as said before it is also a good way preserve the maximum amount of material by focusing the grind on the problem areas. When the glacier recedes I will definitely be employing this tactic on some of my tumble stock. Cheers.

I think Montucky has sent their weather my way.

So I guess it comes from me! Lavic Jasper is named for the location. Way back when, the railroad named "sidings" throughout the desert routes. They made funny names "Zzyzzx" "Siberia" "Cadiz" "Lavic" and johnjsgems will know more I am sure. The area is sparsely covered with palm sized pieces of colorful and highly varied jaspers. You actually park on jaspers when you get to the main site. Here are some pix of stuff similar to the lavic that Jim started with. As you can see it is highly variable.
