Barrel failures on both closed end and open end.Both failures predicted from past designs.Simple and cheap patches will last a long time. Open end failure on old design using 'bell reducer'.No easy repair.And,this is thin wall SDR 35 pipe.Gotta use sch 40. Open end failure on new design using 'bushing reducer'(no pics) occured at bottom of gusseted sections.Solution-filled entire gusseted sections with GE silicon caulk-easy and long lasting fix. 6 incher after +600 days: 8 incher(not worn thru yet,but will): Closed end failure was predicted too.Simply glue a sheet of pvc sheet to the end.only the center 2-3 inches wears thru. The rounded caps are trickier to glue to and were ordered by accident.Best to use flat end caps so sheet PVC can be glued to large flat surface.

Thought ya had a pic of my barrel!Itried different fixes,finally used spray on plastidip with many strips of fiberglass mesh embedded.I don't use this large tumbler often,it should last a long time. snuffy

You got it fixed like a fiberglass patch.Should work well.About how long did it run before it failed?

I ordered 8 inch end caps and they arrived rounded.A 1 inch hole has worn out in the center.It was trickier glueing a flat plate to it.I used the tumbler as a lathe and held a 4 inch angle grinder to it and cut 8 inch circle out of the end.Then glued a plate of PVC to it and used 12 tiny wood screws to make sure it stays. Flat end caps are gonna be used next time.

Very helpful posts , really cool setup. I was just thinking about asking someone what to use to make barles. I had a idea to use a old exercise bike a friend of mine was going to throw out for gearing and a frame to make a tumbler that might work on wind power. I think I got it mostly figured on how to rig it except barle and maybe a breaking system when winds get to high...

Wind sounds great n8.Cement mixers are too rough and chip stones from what i have seen.Maybe for marble or granite.To mix cement kinda quick they set those machines up to run kinda uh violent.

Cool man , and oh duh .. didn't even think of that ... wonder if I can rig it to a smaller engine somehow, hadn't looked to hard at it I was mostly brainstorming what would be a durable container...... I just had a closer look around the site and I admit I'm likely close to the lowest in expertise and maybe age as well. Thanks for putting up with my novice chatterings... I dig the folks here but I don't want to be a nuisance. Maybe I'll study up more before asking too many goofy questions. And trying to chat up everybody.....

Two year old barrels finally wore thru on bushing reducer side.Easy silicon fix. Removing limestone coating off coral with chunks of grinding wheel is super abrasive Notice the silicon caulk fill in the gussets.It is highly resistant to tumbling abrasives This photo shows the wear on the bottom of the barrel(grey spot in center.Easy to PVC cement a sheet of PVC to the end of the barrel

you still cooking rocks in your wife's oven? Or did you find a surplus one somewhere?

Been so busy w/plants.Got a couple of batches to cook.It cooks 30 pounds at a time and is so precision and lazy easy.I would probably go to used restaraunt supply and buy same oven used;but 1/2 or full instaed of little 1/4 oven.Local surplus has dozens of bad boy welding rod cookers but they stop at 500 degrees-too cold.If you over cook you ruin a lot of good rock.Wish i could do wood heat with accurate +/- 20 degree control.Probably can but not interested. Almost went on coral trip w/Florida bud;Suwanee was at 600 cu ft sec,dropping 85 cu ft sec per day.Need 80-220,so we postponed.

So this thread has been pretty quiet for a while, Jamesp.... Anything new on the tumbling front??
Still have not had time or $$ to build my own, but I have found a source for sch 40 pipe in 8 inch diameter, and was thinking if the material is tumbling below the center line of the barrel, then a very tiny, pin prick of a hole in the rubber cap would allow pressure to vent out without losing any fluid/grit mixture in the event of pressure build. I was thinking in the range of and 1/16 inch or less, just 1 or two holes that would, hopefully begin to bleed off pressure before it can build up. you're thoughts?

I know you're asking James, but I'm running those rubber end caps on a slightly different set up. I'm thinking that sticking an ice pick through that rubber cap once or twice might do the job. Since I have an extra cap and in ice pick, I'll give that a try and let you know in a couple of days. I'm seeing the pressure build faster as the ambient temperature rises and right now I'm having to "burp" it every day.

Mario + Russ : A small leak usually reaps havoc. Never tried it on the end cap, but have gotten leaks at the PVC slip joint glue connection and have had leaks there. And that is a about a 2.5 inch glued surface. Fatigue loosens the joint when I connected 2 barrels together and had a glue joint in the center. so I stopped that practice.
My experience is a small leak reaps havoc. But it is a cheap experiment if tried on the end cap....Could watch the tumbler for a while to see if it is leaking.
