I agree there has to be some decent deals on ebay if not at your local thrift store on some piece of hardware. Also a vote for staying away from 3000 rpm for various reasons.
THis particuluar motor is labeled ccw, it may be reversible, but believe that's the wrong direction for the LS-10/St-10.?

I called Belt Inc and spoke with Tom, the creator of the Lot-O.
Sympathize with all the new motor woes. I highly doubt these things were designed with an offset load in mind, and in the never ending quest of reducing costs, I can only imagine the side loads are causing high failure rates as the motors are being used for an unintended purpose.
I'm more curious if anyone knows the Calway/Belt/ Loto - history. I seem to recall having called several years ago and the person I spoke with said something about having just purchased the company?... My memory could be faulty, but if purchased as a business opportunity, the ethos could well be quite different these days?

Looks like China Park is introducing a line of tumblers that look suspiciously like the Lortone products. Where have I seen this before? Sad, can't imagine they'll be able to compete with Chinese labor & lack of regulation. They'll probably claim they "invented" them like the everclean. Just sad.

I just got one (LS-10) dropped off yesterday that had the same thing happen. Emerson Motor, fried the start coil after it stalled, impressive.
ditto to the others, swap the cord, and attach the ground to the cover or frame screws.
It's a bit safer, quantifying the 'bit' is the hard part.

Graves is still in business, That's their logo. I think they've only done Lapidary equipment. If you compare the current thumlers rock/brass tumblers, you'll see a motor similar to yours in the rock(industrial) version, an much smaller shaded pole motor in the brass version as well as a few other differences. Given that, I'll venture that this was indeed designed to polish rock.

The least common dissolved mineral substances in groundwater are the silicates. The most common dissolved mineral substances in groundwater are the limestones and carbonates, specifically ions of sodium, calcium, magnesium, potassium; iron and manganese; chloride, bicarbonate, and sulfate. I'm just going to offer up that Agate is mostly crystalline (micro that is) .
The Crystallization process is MUCH different than a precipitation event, and conditions for crystallization are different for different compounds.
Possibly all the limestone/carbonates/ionic compounds are much more soluble, so even if they did crystallize out of solution, over a long time scale, maybe conditions change enough where they redissolve until you get a compound that is much less soluble and unlikely to (re)dissolve.
The more I think about these sorta things, I realize that I really can't comprehend the time scales involved in these sorts of events, Ancient describes things a few thousand years ago, and these time scales are many orders of magnitude older :0

You can buy an upgrade kit for the bearings on e-bay .
Yeah, I would design something like that if you wanted to use Bearings. It's hard to guess if bushings were a cost savings idea rather than bearings and know which would fair better. I don't think you'll get much life out of 3d printed PLA, Nylon maybe? But the bushings I'm sure are made of a PTFE,UHMW or other plastic designed for this application, and there's a good argument that these would fair better in an environment exposed to SiC dust than a small steel ball bearing imho.
There are plastics with some amazing properties, they shouldn't just be written off en masse as inferior to steel.

Thanks y'all. I'll report back after a few hours using this style belt. As an aside: While I was in small town USA I went to a True Value that had two walls of belts as they serve a large farming community. I didn't expect to walk into such a store on vacation, so my belt was a few hundred miles away at home. "Oh well". if you know someone with a 3D printer, I printed a pair of parallel pliers for making Urethane belts... Think the file was straight off Thingiverse - not sure..

Ditto on Brian's 'thanks for sharing' comments. Many of my few coprolites have been widely adopted!
It's almost Tuesday, so here's one that was a bit different, large calcite? filled void. Sorry, I've already given the other half away. Even non-rock enthusiasts can't resist a dino expellation. ( Colors might be a bit strange as it's been terribly smoky here from the fire nearby )

Ok, does anyone know where I can find (or how I can engineer around the need for) a shaft adapter that has one end (female) which receives a D-shaped 1/2" shaft and the other end (female as well) tapped to receive 1/4"-20T threads?
I have a used 1/3 HP motor I was going to use in a cabbing machine build. However, I decided instead to hedge my bets by buying a better 1/2 HP farm-duty motor with F/B class insulation for the cabber. I want to use the adapter described above to attach a Crystalite Flex-O-Disk directly to the 1/3 HP motor's shaft.
Thanks!
have someone with the right tools face/drill/tap it.

What type of material are the lid liners for a Thumlers Model B tumbler made of? Thanks Mine are old inner tubes

They kind of look like these. Coffee not doing the trick this morning, seems to be linking to it's own thread...

So these storage units belonged to a serious jeweler. He had an amazing collection of material. He offered me a deal on a box of what I thought were tumbling ceramics that I couldn't refuse, this was a while ago. My typical Rockshed cut cylinders are wearing down so I decided to break these out and give them a go. I did smooth the edges for a day in the vibe with some 220 SiC. I ran lot-o loads with a hand full of flats lot of media (and the leftover boring botswana pcs I've added to my smalls/ceramics collection) Nothing came out looking very good. The original cylinders lost their shine, as did the other bots/agate smalls. I'm wondering if these have some other rough stuff embedded that were meant for tumbling metal jewelry pcs or something. Can't ask the original owner, they've moved on.
Seems like I grabbed some one other time and wasn't happy with the results. Definitely not plastic.
Anyone happen to recognize these? ear plugs for scale.

Definitely Ideal/Mojave industries guts. Probably a kit saw or small company like Royal using someone else's insides. Nice saw.
So were Ideal and or Mojave the original parts supplier/manufacturer back in the day? This one looks pretty professionally welded, but the design does remind me of a little 10" R&M lapidary (Salem OR) slab saw I had a while back. Makes sense if there was a design that was widely shared, and the parts seem pretty simple, so kits could have been pretty inexpensive? I'm guessing these predated the Frantom/HP designs that used bearings on the carriage then?
Just curious, thanks for the input.

Need a picture of the guts thanks. smallish poly arbor, some inner greenish paint, Hood mounting looks original (I don't see other holes from different hinges) . Had an Ancient old GE squarish motor on it (that sill runs) and a small gear motor with a narrow belt to drive the autofeed. That was spring tensioned between the motor and an additional arm mounted on the back.

This followed me home the other day (after cutting down the 2" tree that was growing through the base!) The price was worth the barely used Congo blade. Turns out to be in great shape.
Anyway, the guts look pretty identical to a 16" royal saw, but the hood looks uniquely curved to me - it had a 2' chrome fluorescent light fixture across the top, and is stamped made in Japan inside. Could be a replacement hood I suppose? or a home built saw? Just curious if anyone knows.

Here's an interesting specimen cut this morning. I don't recall having seen quite such brilliant jasper colors in your collection yet, but at 119 pages, that's a lot to wade through... Colors seem a bit more washed out on my screen here, very vivid orange/yellow, few fortification lines.
