Hi All! My new Thumblers Model B doesn't seem to be having a good time of it. Frankly, I think I overloaded it but you tell me what you think. The paint is wearing off the barrel onto the rollers, mostly the 2 closest to the front. In some places down to the metal. One of the (bear with me, I don't know technical terms) rubber stops on the front that keep the barrel in place came loose and the barrell worked it's way to the back of the rollers, bringing it to a stop for a while. I glued the stop back on to the rubber on the roller, but it shouldn't be doing this. Is it just so heavy that it's grinding down the barrel and forcing it's self to the back of the unit? or could it be something else? I weighed the rock before putting it in, but my old postal scale could be off. Let me know, guys. I sure don't want to mess up my new baby!

The paint wearing off is normal.My barrels have no paint left at all.As a matter of fact I took the paint off myself.
The plastic barrel guides can be a problem.I redesigned a guide for my 2 model B's and I haven't had a problem for quite a few years now.
That's not going to help you right now but this will.
Put a piece of cardboard about 1" square under the corner of the same side of the frame that the barrel is riding to.
In other words.If the barrel is riding to the right put the cardboard on the right side.
---------------------------------------------- ! ---------------- ! ! ! ! ! ! motor ! ! ! ! ! !----------------! ! ! ! ! ! ! ! ! ! ! ! barrel rides to right side> ! ! put cardboard under this side ->! !----------------------------------------------!
If the barrel doesn't "center up" add cardboard accordingly until it does.
Make VERY small adjustments and you should be fine.
I don't know how this diagram nwill look after I post the message so beware.

Cool. I feel much better. I had actually lifted up one side and I think I over did it. And maybe I can get that roller replaced. Thanks!

One problem that I noticed with the B model is that there is no adjustment on the tension of the belt. I had a problem on a used B model I picked up on Ebay. The motor would run, but the belt wasn't turning.
I tried a new belt and it didn't really help, the barrel moved very slowly. After comparing the pulleys on the old one compared to my new B model, the pulleys appeared worn down on the used B model. As an emergency repair I wrapped the pulley with electrical tape (I couldn't find my duct tape) .
The emergency repair did the trick, the tape added a little bit of extra width to the pulleys to increase the tension on the belt. In addition, some of the stickiness of the tape was transferred to the belt. This repair has worked well enough that I haven't bought a replacement yet.

Us a shim to level the barrel. Even if the tumbler looks flat, or is on a flat surace, it still isn't balanced right.
