Video demonstration of the Thumler Mod B

The ones in my first link are a perfect fit, I have a set on mine

Has anyone else had problems with their Thumler barrels rusting? Mine had multiple orange rust streaks after the very first time I used it, and after about 6 months of light & occasional use the two main seams had opened-up along half their length. Each time I use it a little pile of rust flakes builds-up on the base. I love the results, but the tumbler doesn't seem like it will last very long.

Painted the inside of mine with black Hammerite, no rust now. As advised in the video the inside is untreated and would benefit from some protection.

Oh cock. I Wish I'd known that when I bought it. It's probably too far gone now. I tried to see if the rubber would come out when it first happened, but it felt like it's bonded in. Do you have to 'break' the liner out? It seems like these things are made for a dry process and are being sold for a wet process for which they are not suitable without this extra step. Thanks for the tip though.

Its not bonded or glued but might be adhering to the corrosion under the rubber. Give it a good tug and the liner should come out, scrape of the loose corrosion and then spray a can of Hammerite inside, when its completely dry, wipe some cooking oil on the outside of the liner and refit it, should be ok after that.

Don't despair; if you want I can get you a new barrel. Mine actually came with a little surface rust on the inside and so I painted it with rust inhibitor and then two coats of Hammerite (smooth type.

I'm puzzled that they don't protect the inside properly but I've had mine a little while now and the impromptu pait job seems to have prevented any deterioration.

Let me know if you'd like a price on a new barrel because I might be able to get it at the same time as the machines.

Thanks for the offer. When I get home on the weekend I'm going to pull the liner out and see whether I might be able to keep it going. If I really have to spend more money I'm inclined to look at fabricating something with more capacity.

No the liner isn't glued, it can just get stuck in place with the tackiness of the soapy solution used. Gently lever it away from the metal walls use a wooden ruler or such like so as not to damage the liner.

I've been running a dry Thumler for over on 20 years and it was second hand when I bought it, I've been using the wet one for 15 years but Hammerited the inside of the metal drum when I got it.

They are fine machines and will last forever, well nearly. It is unlikely that that you will need a new drum, just scrape of any rust and clean it, use a rust inhibitor on any patches if you feel it necessary and then just Hammerite it.

I use ceramic media in mine as I find it gives better results and is far easier to manage than the stainless steel pins, that view is currently heresy but I use what works for me.

LOL :lol:

I had to stop myself in the video from referring to the steel pins as "little b****ds". They can and will do anything to escape. I reacquire them with a kind of triumphant glee each time they try it.
