I do not know how close you live from a Grainger supply store. I would take the gear to them see if they have one. If not see if Lortone can send a replacement pulley for the motor and the drive shaft and use a belt/o-ring from Lortone if it fits.

choochoorocks Where you found it, based on a geologic map. It could be anything from marine sediments to metamorphic and igneous, they all roll down hill to the ocean. Not to mention the faulting. To me just from the images I would guess a garnet schist. can you pull off greenish mica with a pocket knife?

I would try the 280 soft and see how it goes. If it needs a 220 you will notice it soon enough.

You will discover Geology will help with the hobby but not directly. If you like minerals take a mineralogy class at a local college. You will learn crystallography and how to ID minerals by physical properties. This will only help marginally for lapidary work.
for finding rocks find out which class they recommend if you want to learn about geologic maps. The State Geology department and USGS have geologic maps and different eras and rock formations have different minerals. as in you do not find fossil fish in a basalt formation. Books on rock hunting sites are helpful though many locations are not available and many minerals come from mines where you will never ever have a chance to look.
There was someone on here in the last couple of weeks looking for rock hunting near the Smokey Mtns. There is not a lot of good natural places and the links on the web have a lot of bovine scatology (BS). many rock descriptions in the books and web are poor. June Culp Zietner from the 60's was a good example. She referred to "desert roses" but depending on the areas she talked about she called selenite roses, barite roses and chalcedony roses all "desert roses" I found this very frustrating.
Join a rock club and go on collecting trips with them to start the ground running.

I used the summ icon. I ran a calculator on it. I then moved all the amounts to another column making them positive and got a good number. I used excel a lot at work. Creating spread sheets from text files and creating delimited files from spreadsheets. It was mainly formatting columns not using the power of the product. The 1099k change came about as part of the covid stimulus package as away to generate revenue to pay for it. Congress votes on things that they have no real world experience with. If I buy a toaster, replace it with a better one and sell the original on ebay that isn't income. If I buy a toaster at Goodwill and sell it on ebay, there is some income involved but not the total amount. Considering the state of congress, the best a person could hope for would be another stay of execution. I went through this exercise in 2022 but didn't need to do anything with the information Some politicians think if you make $100,000 per year for 10 years that you are a millionaire and should pay taxes at that rate.
I read an article by bank of America yesterday that talked about the wealth transfer of $$ from the government to baby boomers. They think wealth comes from the government and was transferred to baby boomers because the government creates inflation so their houses/land increase in value over time. To me that is not wealth transfer but poor money management by the government/banking system.

This looks like a sulfide ore like massive galena. What is the hardness? What color is the streak? Gray possibly galena, black magnetite, red hematite though it does not appear to be hematite. Is it magnetic?

Wonderstone (rhyolite). Looks like the material from Wonderstone Mountain, Nevada. I always heard Hickoryite was a wonderstone rhyolite. (?) Hickoryite is a variety of rhyolite. So is Wonderstone. Rhyolite is a generic geologic name for a fine grained volcanic rock with the same make up as granite but with microscopic grain size. Hickoryite and Wonderstones are simply Lapidary names that cover a specific location or region. Typically with a specific properties like higher % quartz and takes a better polish than some other rhyolite.

That’s cool, Live Oak is a small town literally smack dab in the middle of Northeast San Antonio. My cousin lives there. Takes about 20 minutes for me to get to his house. They have really good Christmas decorations in the neighborhood during the holidays. I wonder where people actually go. Rock hunting there. It’s only a few blocks practically. I thought it was all city… OK I did not know there was a Live Oak "City" . I assumed Live Oak County TX. I live and learn every day.

Looks like a type of rhyolite. Do you know where it is from?

Amber is real light (low density) compared to quartz. Topaz is too heavy compared to quartz and H=8 so easy to test with scratch test from known quartz crystal.

Back in the old days they used alcohol to keep water from freezing. In the summer it would boil off so they had to add more in the winter. That is before antifreeze aka ethylene glycol-based and propylene glycol-based solutions

I purchased a pump for a DP Titan geyser and it requires more air that the geyser for a DP 6" machine. I also wanted to be able to run both geysers at the same time if necessary for a class. So I found the following that all met my requirements (in August 2020):Piston driven Air pumps: Coralife 05146 SL-65, 3.9PSI, 2.3cfm(65L/min, 35watts @120v Better option** $70.45 on amazon Marine Depot 87.49 Ken’s Fish $79.99 chewy.com $70.45 walmart $76.99
Active Aqua AAPA70L - 70L/min =>2.47cfm=>1110GPH, .03MPa=>4.3psi, 60watt, 60DB Better option** $67 on Amazon, Ebay $60.11 44.65
EcoPlus Commercial Air 3, (Model 728455), Single Outlet pump 1030 GPH => 65L/Min => 2.3cfm, 3.8psi Fresh Water Systems $47.99 Horticulture Source $45.49 ebay $54.49
O2 Commercial Air Pump Aquaponics: 794 GPH => 50L/Min(1.76cfm), .03 MPa => 4.3psi, 35Watts about $49 ebay
Air pumps are like electricity with PSI=Voltage and CFM=Amperage This would be probably more than you need but the price is not that much more. I ordered off Amazon for $40 and it never came so I canceled the order and found a place That did fish and hydroponics and it was about $70. Been working great since.

Check out the link for the “grand Monster Tennessean.” my.vanderbilt.edu/universitypress/2021/10/08/author-conversations-mastodons-to-mississippians/It turns out that if you do not have the the head or feet bones of the mastodon and you mount it upright it looks like a human skeleton. So were the missing pieces just lucky or by design. I know that back in 1845 they charged admission to see it. So maybe the missing parts would have confused matters, so best to leave them off.

FWIW if you are close to a place that does scrap metal recycle or gold/silver purchases check to see if the have an XFR analyzer. That might give you the Cu and Zn ratios to prove Rosasite. From Wikipedia: Rosasite is a carbonate mineral with minor potential for use as a zinc and copper ore. Chemically, it is a copper zinc carbonate hydroxide with a copper to zinc ratio of 3:2, occurring in the secondary oxidation zone of copper-zinc deposits. It was originally discovered in 1908 in the Rosas mine in Sardinia, Italy, and is named after the location. Fibrous blue-green rosasite crystals are usually found in globular aggregates, often associated with red limonite and other colorful minerals. It is very similar to aurichalcite, but can be distinguished by its superior hardness. H=4

The ring looks like a 12x10 mm this is a standard size on many traditional templates. Mark the stone with a pencil then grind to the line. Except grind 1/32 or so outside the line all the way around. (Note*** you did not say type of material.) If soft stone leave more space. You should be just outside the line by the time you get to the 220 grit. grind lightly with the 280 just to clear off the scratches from the previous wheel. Once you get down to 600 you do not have to worry too much about over grinding unless it is a soft stone. finish as normal. before setting flatten back on 280 if needed. put a chamfer or round slightly the sharp edge where the back meets the girdle with the 600 grit wheel. This keeps the prongs from chipping the back if it does not fit 100%. One other thing even standard sizes vary from manufacturer so depending on the template maker and the ring maker there may be some variation.
