Well, the guy already removed the craigslist ad - darn it - but... A listing in Tampa for a Thumler's Model B (15 pounder) for ............................. 25 bucks care to guess who just got home from Tampa? I wish the ad was still up. He had a picture of a listing of it from somewhere showing the actual cost. So, he knew what it was worth. $25 *snort* He only used it a couple times to tumble some guitar parts (??) whatever... Full disclosure - it is missing the barrel liner. He threw it away.... Can get one from the Rock Shed for $42 + shipping So, for around $75/80 I'm adding my 4th Model B to the tumbler shelf. Got it running out on my back porch right now. Seems to be just fine after a little oiling and Windex. *woot*

Nice score, captbob! Wonder what the previous owner was doing tumbling guitar parts, and without the liner, in it? guitar picks, maybe? Santa good to captbob. Looks new. Now show the bag of coalROFL, jamesp!!

He probably kept the liner because he was a terrorist (or just making firecrackers) and was tumbling high explosives to get a better mix, the liners absorb the powder and become volatile afterwards.

The purpose of the 40 is to feed the 12. It would take forever to get enough rocks worthy of doing a polish load in a 40.

I could pick up a 5 gallon bucket of tumble worthy rocks in a day.. depends what you mean by tumble worthy though... I also tumble all the flint knapping scraps that my friend gives me. If you don't go out a lot it is hard to fill though. most of these are small also... some may be cab quality but too small to cab. Some of the rocks I see posted on here that look nice when tumbled I would pass up on in the field. This summer when it comes I'm hoping to find enough to fill the barrel at least 3 times in polish like this year... But i want to find lapidary worthy stuff even more. Once I get caught up on tumbling I will probably save all my material and tumble only in winter time... After my polish loads are done I will be starting rough with the flint.

Order extra lid gaskets while you are at it. It is the weak part of an otherwise good tumbler. Or make your own out of two ply neoprene or something tough. The liners are guaranteed for 5 years. The lid gaskets if tumbling rocks have no warranty. Or at least that was the policy when I was a dealer.

You can also spray a good coating of plastdip on the lid,especially towards the middle where it wears out first.Did mine and never had another problem.Tape off the edge a little and spray away. snuffy

I've already got 4 extra lid gaskets on hand. Probably a dozen belts, spare bushings, even an extra drive rod with the pulley on it. Just the way I do things. My wife loves it Actually, I think that she has come to appreciate that when she needs something I probably already have 2 of whatever it is stashed away somewhere! Can't believe I didn't have an extra barrel liner on hand And, Glenn... it's just not worth my time. Carry on!

Good find, nothing like getting something that near new for cheap, even though you need a liner.

Nice find captbob. The Scott Murray tumbler I got from Mr.mohs a couple years back required a new liner. That AZ heat and sun is not too kind to rubber parts! It uses the same liner as the Thumler Model B. Yep, picked one up from the Rockshed as well. Even adding cost for a new liner, I'd say you got a sweet deal. While checking into that tumbler back then, I found that two models were made. One for rock tumbling, one for parts/brass tumbling. The only difference between the two is the revolution speed, the rocks being slower (I believe). If the previous owner was tumbling guitar parts, wonder which speed this one is? I imagine it would be easy enough to change with different pulley. Craigslist can be a boon, or a boondoggle, lol. I have to refrain from visiting that site.

Yeah, it is more cost / time efficient to just buy stuff I just like finding stuff and my ultimate goal is to go out at least once every week in summer months to specifically find rock. Let alone the rock I find while i'm working (I come home with on average 1 lb of nice rock per week or more) Also how thick is the rubber gasket on that?

Some are much thicker the Lortone is about 1/16 and is EPDM rubber. EPDM will stand up to sand blasting. Anything that is presented to it just seems to bounce off. It is doubtful that anything will ever get thru it. Remember Teflon Don, teflon is non sticking, nothing ever sticks to it. A good analogy.

I imagine it would be easy enough to change with different pulley. I was thinking of that driving home from Tampa yesterday and figured that I will wait until I have a load in it to count the revolutions. I'm not sure if the barrel being empty would allow it to turn faster than when full. If it's the faster model I'm good with that. I'll just use it for coarse grind only. Correct on the rock model being slower. My house already "hums" with 3 of these 15 pounders running. 4 ought to get the neighbors commenting. I had a neighbor come up to me awhile back and ask if I had found the bee hive. Was sure that there was a hive somewhere near by due to the humming.

Gotta turn close to normal speed whether full or empty captbob. Guessing the motor would burn up if it was turning even 10% slower. probably just a simple pulley change to get the correct speed
