The ratios of time / patience and coarse grit are inversely proportional: - More time <-> less coarse grit
- Less time <-> more coarse grit
Add a small amount of coarse and then recheck in a few days. Recharge with coarse as necessary.

First "Starry Night" I've seen since Vincent. Thanks for including it! Do you know why Van Gogh painted the lights with swirls of light around them? I know there are one or two theories with substance (so to speak) Never had any myself although I know it had a resurgence of popularity probably around a decade ago. Oops thread drift again! Sorry Tommy.

BTW...I always heard that shattuckite was named after a guy named Shattuck, so that might determine a slightly different pronunciation, with the "ite" as it's own syllable. I believe you are on the right track. My understanding is that it was named after the Shattuck mine. Yeah, amazing cabs. The purple wrap is a literal jaw-dropper.

I'm now working on a laptop that was charged through the day and now I've spun the solar panel around and it is keeping the battery charged from the room-light.
A pic to follow tomorrow when I hope to hook up a tumbler / grinder

All beautiful! My fave is the Royal Imperial Jasper - that is a total mirage of a stone!

Just be aware you've dug up an old thread. Alice was last online on 17 September 2015 so don't expect a reply anytime soon. There's always a chance though.

I am not acquainted with a "pendant " bit. 'Just tried to look it up but got numerous hits detailing a wide range of jewelry making equipment and their attachments. Could you please point me in the right direction? If it cuts down in the dust... then that is a plus! Flex shaft ... my bad Yeah I borrowed the term from jewellery making: next best thing Dremels are just too fast and don't have the required torque Micro bench grinders can run slow and slower with low inertia / have variable speed & you can wet the cutting disk / shaft without fear of frying unless you're making a really bad job of it.

I stumbled across this youtube video and with a careful bit of ebaying have secured all the components inc 12- 240 v transformer and circuit breaker for around £85. I just need a battery now, which I need to research before choosing a 2nd hand car battery or a new 12v leisure type but comes in at £15 - £22, so all in for under a ton (£100). I've added a 12 amp hour battery for £22 10m cable £10 enough to link present and a future panel MC4 connectors £3 SubTotal £35 Original spend £85 Total to date £120 for 60w solar panel I can expand this system with some MC4 branch connectors £6 Additional solar panel at cost ~ Wattage Additional charge controller ~ solar panel output A second inverter (300w needed & first was 150w) £17 (same cost as the first) - is included in real cost of project but not needed to recreate this. Just waiting on this to arrive now, so this is the only thing delaying the project now. The panel is wired and has charged the battery.

Just as a point of reference, 750 Watts = 1 horsepower. Cool ... so my 1/3 hp motor should run directly from 250 Watts. At present I have 60 Watts; assume 10% drop off due to inverter and cable that gives 50 Watts and I'm being conservative. So for every 5 hours of daylight I should be able to run for 1 hour. If only they would run on darkness instead of sunlight - I tend to want to cut more in Winter when the nights are longer.

Full marks on the PPE I think a key contributor to the dust is the speed. I had just the same from a dremel; now I use a pendant bit from a small bench grinder and just keep dipping it so the cut face is wet. That will do until I get a small tap drip-running continuously.

My partner recently bought several pieces of rough chrysocolla in apache gum (I'm not 100% certain what that is, but I've looked it up and it seems like it should be fine to tumble those pieces as is). I'm looking for other stones that are around 3-4 hardness that I could tumble with these, so that I don't end up scratching things up or grinding the pieces down to nothing. I have some calcite which seems like it would work, and I think fluorite might be okay too, but I don't know of any other ones. Any suggestions? (Also, I'm new here! Hello, my name's Charlie, I'm from Wisconsin.) Welcome Charlie! A small amount of homework to doHomework part IIBut perhaps this is too much data and not enough information. I'd recommend: - Amber or Copal
- Apatite
- Bornite (apparently people do tumble this!)
- Dolomite
- Fluorite
- Marble
- Rhodochrosite
- Soapstone (some: Steatite)
- Sunstone
- Turquoise (just a bit harder)
Soapstone hardness

I'm sorry, but, military is overrated. You oops up and they want to execute you or give you 20+ years for any transgression. I guess that's true for every military! I sincerely hope, that, in the future, Americans won't have to sacrifice their life for their country, as we could just send robots to destroy our enemies. But that's like 40-50 years from now... Fight smarter not harder. That future is already here Adam. In the future, yes, this is likely to be even more so. I was reading about mine detecting ' turtles' being trialled just last week; skeeter drones. You probably have more / different in the US.

It may be volcanic. It may have crystals (certainly!) and it may be unusual... but it doesn't look like any scoria I've seen (or maybe it does). Typical scoriaScoria is by definition bubbly; so light as to resemble honeycomb in texture and (relatively speaking) weight; and due to the very rapid cooling by virtue of being ejecta, the material is often glass or crystals are usually microscopic. There is a way that this could be scoria and yet appear to be as compact as it is and that would be if it were to be mineral filled by virtue of being adjacent a fumarole. In which case I agree with the recommendation that you wouldn't want to wash it in water.
