Very nice cab, Bob! Although, I must say it's got a rather phallic picture...

Very nice! What do you use for hardener? I've used watered-down white glue, but I'm wondering if there is something better...

In addition to a scratch test, a streak test helps identify minerals. If it leaves a red streak on rough porcelain (like the back of a porcelain tile), it is likely hematite.

It looks like chert from here....

It does look like chert and I would expect the vugs to go all the way through. One cut would confirm, but that's been my experience with similar rocks.

Ditto the two bucket, paper bag, and trash method with mineral oil.
I use a 4" drywall knife to scrape it out of the bottom of my 18" saw. On my 10" I use a vacuum slab saw sucker (can't remember what we previously called it here on the board). It's a sealed bucket that goes between the wand and the shop vac to catch the sludge.

I think all polishes get into the cracks and crevices, but since the titanium is white, it's much easier to see than, say, cerium.
Titanium dioxide is the first polish I used for tumbling and still have some.

I thought about creating a new ID, but I have enough crap rock. Chuck

I'm not sure how I would identify "a small stainless steel cylinder approximately 7 inches long and an inch across...stamped with the words “danger radioactive” and “do not handle” along with a radiation warning symbol" from 25 feet away.

I agree with what others have said regarding mixed hardness rocks. Lake Superior agates are a good first load because they polish easily.
Having said that, they also chip and fracture if you don't have a full load. So, keep your barrel about 3/4 full with water to the bottom of the top layer of rocks.
Others have mentioned the need for small stuff, I thought I would clarify a little: about 1/3 of your load should be pea sized or smaller. If you don't have rocks that size, use filler as herchenx mentioned.
Hope that helps! Chuck

Yep, I've been to Yellowstone and Mammoth and I've seen the thermal features. However, those thermal features often carry a lot of minerals, some of which may be deadly if consumed by a grizzly.

Wow. Kind of wish the grizzly had gotten him, provided that whatever burned the bison didn't make it sick...

Like Randy, I use my 10" saw for slabbing fist size and smaller rocks. My 18" saw still handles the big stuff, but I've used my 10" a lot more overall.
I've also used it for trimming, but prefer my 6" trim saw for that because I can use it inside with water.

I've been here a while, but like Sherry I don't post as much as I used to...I haven't had much time for rocks lately as I've got other things competing for my time.
FWIW: I also miss HPD. Glad bobby1 is still around.
Anybody remember Earthdog?

This is likely my last post on the topic, for reasons you’ll see at the end of it. Mel: I can see you're a skilled debater as you muddy the water by switching topics , but they’re really not germane to the topic at hand. Nonetheless, I'll respond to them: 1. This and #4 are really the crux of the argument. While the Mini-14 and variants may be popular hunting and varmint rifles, that is clearly not their originally intended use. In fact, the Mini-14's name and design are derived from the M14 military assault rifle. From wikipedia: "Ruger offered a selective fire variant of the Mini-14, the AC-556, to police and military customers. AC-556 models have a slightly longer receiver… to allow for full automatic operation. These models are available with features such as short barrels and bayonet lugs. The Mini-14GB model is a semi-automatic variant for police and military use with the additional factory options of a short barrel, folding paratrooper stock, flash suppressor and a bayonet lug." Tell me again why civilians would need these features? 2. Which LA riots? The ones that erupted after Rodney King was beat down by police? The ones where Reginald Denny was pulled from his truck and beaten? I really think this is a specious argument as those riots did not spill over into Hollywood, Beverly Hills, or countless other communities. Did civilians armed with assault rifles jump into the fray to try to protect the innocent? I didn't think so. Switzerland is an anachronism that developed from the wars in the early part of the 20th century and forced conscription. Do you really think Germany, Italy, or France is going to invade Switzerland today? For that matter, do you think the Mexicans are going to swim the Rio Grande, assault weapons in hand, to attack the Republic of Texas? Remember the Alamo? So the poor folks in the ghettos have the money to buy assault weapons but not food? I really think that fear of people “not like us” drives the demand for assault weapons as people imagine societal breakdowns. Aside from the Civil War, in our 236 year history we’ve never had one on a scale where the average citizen has had to take up arms. 3. To your earlier point about not allowing citizens to carry machine guns: if assault rifles are easily converted to machine guns, then isn’t that something we should prevent? Doesn’t converting one automatically make someone a criminal (even if you’ve never used it to commit another crime)? This isn't about the cops and perceived incompetence. If you read the article I linked previously, you'll see that the cop used his pistol to bring down the robber who had a guess what? Mini-14 (with armor piercing bullets, by the way) 4. I think it is precisely our business as a society to engage in this debate and decide whether the cost in human lives is worth the benefit of people having whatever weapon they choose. It's yours, it's mine, it's the business of all citizens. And that is exactly what you and I are doing. 5. Of course it is a war rifle. However, ALL guns were originally conceived to provide the ability to kill at a distance. (The number of guns designed for strictly target shooting, like the Olympians use, is miniscule.) The Mauser has a 5 round clip. Even with stripper clips it is very slow to reload. Those seconds can mean the survival of many as they either attack the shooter or flee. Again, back to the article, the assailant with the assault rifle was killed while reloading. Which brings me back to my original point: a semi-auto assault rifle, even if it has not been converted to full auto, has the potential to rapidly kill and injure many, many more people than other guns. Do we as a society want them easily obtained? How many lives is that worth? I just read the stats on gun violence in the U.S., again from Wikipedia: “In 2005, 75% of the 10,100 homicides committed using firearms in the United States were committed using handguns, compared to 4% with rifles, 5% with shotguns, and the rest with a type of firearm not specified.[38] Due to the lethal potential that a gun brings to a situation, the likelihood that a death will result is significantly increased when either the victim or the attacker has a firearm.[39] The mortality rate for gunshot wounds to the heart is 84%, compared to 30% for people who sustain stab wounds to the heart.[40]” So, maybe I’m getting worked up about a non-issue because of the Aurora shooting and the bank robbery close to home. Still, I think it’s a debate worth having and the country will continue to have. I enjoyed the debate and didn't take it personally. I hope you didn't take it personally, either. We can agree to disagree on this topic. Thanks for the tip on the ammo. Chuck
