I am suspicious that aliens named it originally. siding ?? And the foliage has all been eaten away. You guys know that the deserts out there are all naked cause the aliens eat the plants at night.... And lavic jasper is not of this earth, lots of alien language in the patterns. 3 dimensional alien information nuggets

This spot along the river gets colder than some of the people i know at the base of the mountains. Go figure. If you live in the city it's warmer...

To heck with all that waiting Chuck. And electricity, wear etc. 2-3 hours grinding on 15 pounds and they have great shape. Kinda do not tumble unless pre shaped any more. Pre-grinding is always a good idea. Even with slab extras. A few minutes at a good grinding wheel can save weeks+ in the tumbler. When I'm doing a coarse grit clean out, I usually have a container for stones that could be fixed easily. I work on them during the week and then they go back in at the next clean out. If I like a stone that can't be ground easily, I let it ride in the tumbler a while longer. As soon as I can tell that I don't like a stone or it will never amount to anything, it goes down in the alley as gravel. SiC is too expensive to waste on stones that will never amount to anything. jamesp, you obviously have it figured out. Your stones look awesome. I can't wait to see them polished.

Thanks starguy. Segregated stones are in containers. Smalls, mediums and large. Single fractures that could be broke and recovered. Partially finished to add at coarse or finish steps. But the pre grind saves the most grit and electricity. Not to mention they have the best shape. Most of the stuff gets trashed after it has been in coarse grind. Thats's when a lot of defects are found. Those garnets are another level. The color alone, not to mention the stars. Thanks.

Those will be some nice smooth pretties. For those who only have a vibe tumbler, one can "clean" grind tumbles on a tile saw to the point they can go right into 220 in the vibe. A good soulution for those who whis to shape/smooth their stones and do not have a rotary tumbler. The last pet wood I polished was only done on tile saw and vibe.
I tried to grind on my shop grinder before getting the tile saw, slow going, and had to keep cooling off the stones in water.

Most tile saw blades run about 50 grit. My diamond cup leaves deep scratches to what looks like 30 grit.(judged by comparison) The 30 grit shapes fast and i do it dry. It stays totally cool because it grinds at such a high rate of removal. No heat, even dry. But high removal rates typically are cooler. The tile saw never gets hot. The water cools fine. Five days in the rotary in coarse grit and scratches are long gone. I think a vibe w/220 would do fine too. I use both ways and prefer one over the other depending on the stone.
The tile saw is safe and reliable. The diamond cup spins fast and is easy to burn your finger tips on. Cab size rocks are not safe w/the cup. But i have never come close to making cabs like you can do on the tile saw Bill. The tile saw would do that best.
