I have been in the tumbling awhile now and have had my go around's with trying different equipment reading and learning along the way. In the matter of the last couple months I have had 3 blow outs in two QT66 tumblers and two of them back to back today. On my two Thumler B's a stick of dyn "O" mite couldn't blow the ends off. I haven't had a drip on them. There is something to say about that gasketed end with wing nuts I think the hexagon barrel gives more action to the media inside also. For these reasons these two QT66's that have less than two months runtime along with spare parts will be listed in the 4 sale area. I have ordered two more thumler B's from Shaun at TRS. ~Duke

Sorry to hear that Duke. I have had no problems with my two QT66 units after 15 months of continuous operation... still think highly of them... but I can't fault the Thumler-Bs either. They are good work-horse tumblers also. The Thumler B's 15 lb capacity is tempting because I am having a small problem right now keeping my UV-18 fed. Lol! ('can't go larger than that... I will run out of garage space, and my Daughter's car would be relegated to the street... not good... I like my dinner bowl!)

Maybe I was just having one of those days. First Blow Out was with room temp water. I read on here ya wanted to use warm water so I warmed up the water to expand the contents a bit then when it cooled it would be in a slight suction offset to keep contents from expanding? Maybe it was just to damn warm hells bells I dunno. All I know they are to finicky for me to goof with. Since I got STROKED last year I have a short fuse and in my Crapman Toolchest I have a BIG DRAWER that houses SLUGGO actually a few SLUGGO's my favorite tool there has been many things that have went for a walk outside in the driveway with me only to meet Sluggo and their end of life. Luckily when this happened today I left MJ out there to clean it up and went in the House to cool off. So I will work up a good price for someone my loss is their gain. Here are a couple of my British Constituents from the Duke's European Chapter of repair. I have trained these Blokes to Fix Power Jack Inverters. Sure may not run quite as good but sometimes you just have to go for it as it does make you feel better!

First I find the lip of the lid to be too straight. I have taken a ball-peen hammer to dimple the lip, at the curve, to put a pinch point at the upper lip of the barrel. That will help hold the lid, to keep it from popping out. With the last lid I just put a 1/4" wide piece of gorilla tape around the inside lip next to the rounded edge. Also when I put the lid on I have the barrel sitting on a rock to put a dimple in the barrel bottom. With the dimple in the end you can watch for expansion and catch it before anything happens. Lets face it, if you have the wrong combination of rocks enough pressure can built to blow or leak from any lid. Good Luck............................MrP

Selling any parts? I’m looking for the main units minus barrels but would consider barrels too

Hi,
My opinion is a chemistry issue resulting in gas creation, thusly blowing out a less robust sealing mechanism.

Maybe I'm just lucky, but my QT66 and 45C's have not given me problems at all, and I have no issue with any gas/pressure buildup with what I've been rolling. Now that I think about it, did they actually blow out and shoot crap all over (gas buildup), or did the lids just come off? 20 years ago, I didn't have a lid completely seated, and it worked its way off. That spill happened within about the first 15 minutes of starting up the tumbler, and I ended up seeing it happen. That's the only spillage that I've had...knock on wood.

I’m surprised to hear that you’re having issues with a Lortone barrel. I’ve been running my QT66 for about six years nonstop without ever spilling a drop of slurry. I ran glass once that made the bottom bulge, but in never leaked. My three pound Lortone barrels have been trouble free too. I have had to replace the rubber lid liners in both size barrels occasionally, but even when they eventually get a hole, the slurry gets between the metal lid and the rubber, but has never leaked outside of the barrel.

Eight years with nearly constant use on QT12's with never a problem. And I brought them, rollers and barrels used. Just sayin'.

I have to believe that if they are blowing open you probably have some kind of marble or limestone in them, or other materials with calcite. We also have run the 6 and 12 pound lortone barrels with no issues. I have heard of folks burping the barrels with questionable loads by opening them and re-closing them occasionally. Cleaning all mating surfaces spotlessly is also a key to leak prevention with all types of barrels.

Considering heat often acts as a catalyst, perhaps warm water isn't the answer. I too have been running Lortones for years, QT6's & 12's, NEVER a problem. Those lids really need to be screwed on tight, w/o having to use a tool to tighten it, That said, I have always needed to use pliers to loosen that nut. I just don't believe it's a Lortone problem in this case.

Cleaning all mating surfaces spotlessly is also a key to leak prevention with all types of barrels. I tumble a lot of Petoskey stones, which are calcite. They cause no gas expensing provlems for me. Maybe calcite from other sources is different, I’ve only tumbled local Michigan material.

I have been using hot water when starting a load. In about 15 minutes you can see it sucking the bottom of the barrel inwards due to the water cooling off. Seems to take care of any gas expansion that I have had. Though most of my loads are agates, jaspers, and quartz.
