Don't sweat the specific id's. You had a great rock hunting experience and selected good material for lapidary. I see agates, I see wood, I see wonderstone. Go forth and make them prettier or cherish them as they are.

The cast iron construction also accounts for the early death of some machines. I had one that I traded to a friend and he promptly broke part of the vice and as is commonly known welding that stuff is not easy.

I have the older version when it was made of pot metal and one had to be careful in freeing the bearings from their mounts or breaks would occur. Ask me how I know that. Easy to work on if the bearings move on the arbor.

And one of the things often found where there is hematite is limonite. Does it have a streak thats red or one that is brownish ochre colored? Maybe its not a jasper agate at all.

Or if its a red streak it will be some other form of iron oxide like hematite.

Is this the same stuff that railroads used to cover railbeds with and that every post WWII high school used on their track ovals. If so, everyone over 70 undoubtedly has it ingrained in the palms of their hands and knees. Railroads used deposit such cinder just about everywhere someone would tolerate them.

Thank you all for the nice comments. Hopefully start cutting tomorrow, still trying to decide to use a recirculation pump for the oil, which it came with or use the bath approach. If I understand the saw correctly it (the blade) runs backwards from most saws and hence using a bath cooling method might cause excessive (more than normal) amounts of oil to be thrown forward (toward the user). I suspect you would be best off with a well moderated and focused pump feed for the oil. Its all related to the unique vice setup. Let us know.

2 could be a brown rhyolite.

That is probably one of the most uniquely designed saws in the field and the perfect one for cutting rounded rocks like thundereggs. Enjoy the ride.

There are four quite distinct kinds of skunks in Arizona and New Mexico. Some species are more prone to spray or have a stonger scent than others. However that said, the photo looks to contain only striped skunks (the species most of you are familiar with). Spotted skunks are quite like their name. Hog-nosed skunks are adorned with an almost entirely white back coloration. Hooded skunks lack the diverging Y of the white stripes. And common striped skunks almost always have a white coloration that splits into a Y behind the head or further back on the body. The mostly black one that Bev mentioned just has a narrower white pair of stripes than the others. A happy unmolested skunk may have minimal to no odor.

They both were preformed on an 80 or 100 wheel, given a kiss on the 220 nard and 260 nova wheels and tossed in to a vibe (microsonic). I'm still not satisfied with the polish but that"s my problem of rushing the net.

Damn. Its amazing that we see things each to our own perspective. Politics, religion, rocks. . . . ?

Playing with new phone camera and could n't help but further hijack this thread with a piece of Ohio flint recently in process on my bench. I beg forgiveness for the photo. Now this is a complex color pattern. and this was reported as being Ohio flint as well. go figure.

The same quandary exist in New Mexico where the Spanish speakers named Pedernal Peak(meaning flint peak). Made famous for two reasons. O'Keefe liked to paint the flat topped mountain and more importantly the prepueblo Indians often called the Ansazi made 90% of their tool that were not obsidian from the( yes) chert from the Mt. The rock hounds came along and often termed the material agate (hey it was colored black and pink and whitish so it wanted to be agate. We lay folks just think we know what we are talking about.

Cool. Thats the kind of place where just sitting down and examining everything within reach for 10 minutes and then moving would be productive. Wetness is good, coldness is not!

Don't I remember a thread who someone authoritatively opined that Ohio Flint was not flint but . . . .?

To prevent that thin slice sliding into the space between the blade and table, find a thin sheet of plastic (a cheapo cutting board will do if thin enough) and use your saw to create a slit an appropriate depth in the sheet so that it will position around your blade. Any contact with the blade will merely enlarge the slit a bit, but the gap causing the problem will be covered. Such jams may be causing your warped blade but not necessarily.
