Mark, that's exactly the tank I have and can't get anybody to take it either. Might as well turn it into a barrel! I also have a can of that tool dipping stuff that's been sitting around for years. Sounds like I finally have a use for it!

I'm on my way to the HD this afternoon to explore possibilities. I'm going to look for tyile blades and the 16" plywood rounds. Post a thread if you use the vinyl stuff on something. I think its a great problem fixer for sealing, leaks, etc. It could even be used to create gaskets.

I can't get the item to come up- message says item currently not available. But, yes the fiberglas idea would be viabkle, I think, but could be messy and costly. I couldn't find the plywood rounds so I guess I'll have to make them.

Line the inside of the tube with truck bed liner material, waterproof the outside if necessary. The rounds were by the pre-cut plywood and table tops I think. Oh well, at least they're not hard to make . Dr Joe .

I just checked the link and it worked for me. Maybe because HD checks to see what is available in your local store?
I ran into the sewer guys last night and they promised to drop off a piece or two of PVC today. We'll see.
Does truck bed liner really hold up that well? I don't have any direct experience with it...just asking.
Yep, I've cut the rounds before and they're not hard to rough out, but they are a little challenging to get perfectly round. On the other hand, they don't have to be perfect as long as they turn.

Yes, the bedliner stuff is tough! Well, at least the spray in stuff is. I would imagine it would hold up nicely inside a barrel. I don't know if the DIY kind is as good. I do know one guy that used it, but I don't recall what he thought of it. Has anyone thought of using the rubberized undercoating you can get in an aerosol can? It holds up pretty well under a vehicle. I would imagine if you had good adhesion inside your barrel it would also hold up well.

If you used a piece of 6-10" PVC pipe you could cut two plywood circles and offset them slightly when you tighten them down on the pipe so the whole thing goes slightly side to side as it rolls. Maybe that'd help with tumbling... About the gallon-size plastic bottles: why not evenly wrap with duct or electrical tape to prevent cracking?

The only problem with offset circles is that it starts the whole tumbler rocking and shakes things loose. I haven't tried that exact method, but I have used plywood circles that were not perfectly round and that was the result.
I've tried tape on barrels and rollers before and it wears off very quickly.
The buckets just don't work very well. If the sides don't fatigue out, the rims near the top start to get flat spots or fatigue. If not that, then the tops fatigue and crack where they meet the barrels.
I don't mean to sound so negative! I've just been there already; maybe others can learn from my experiences.
Thanks for the suggestions and keep them coming! :-)
No sign of the sewer pipe yet. :-( But there's still hope. The sewer guys just haven't been back in the neighborhood.

OK, guys, I found pine rounds at Lowes. They're 1" thick with a bullnose edge. I haven't seen any DIY bed liner material. It's a polyester resin as I understand and very tough. I do wonder if the surface would be smooth and not trap grit. Another problem might be getting an even coat inside if it's sprtay in. I'll do some research. i plan to make an octagonal wwooden barrel (.5" long and about 6.5" outside width per side . the final diameter would be about 12" between parallel faces. I'll gorilla glue them in place and tack them with my brad nailer between the rounds. I'll drill out one round in the middle to hold a 2" length of PVC 3" pipe and use the test plug I just bought for it. i'll waterp[roof it with vinyl tool dip or maybe bedliner material, if I can get comfortable using it. In any case, that will give a final width of 11.5" and a capacity of about 1/2 cubic foot in use ( 1/2 full) or about 3.1 gallons of rocks and slurry. The nice thing about this design is that if I add more sides I can keep even small loads tumbling effectively. The octagon is easy to make, too. Just cut your board to width and cut a 45 degree bevel on one side. Butt joint the next board to the edge of the wider side of the board, orienting the bevels outward as you go around that will create a lip inside to enhance the tunbling action. you can make cool wooden wastebaskets the same way. If you want to get fancy, use a dado head tyo offset the beveled end, cutting a groove the thickness of the board and about 1/8 deep in the inside edge of the board to receive the square edghe of the next board. Then you have a shallow rabbet joint. which makes alignment easier and the joint stronger. I thought about cutting the access hole in one of the boards for the plug, but if it leaked I'd have a bigger mess. i still haven't given up on a gallon glass jar with a coatin g inside. Only three more giant dill pickles to eat and I'm there......

I have about 8' of 10" PVC and 6' of 8" PVC and you guys have given me some great ideas... I am planning to slice off pieces about 6" long to use for the barrel. I like the threaded rod idea, but I'm thinking about fiberglassing some 12" disks to the ends ( wood or plastic, depends what I can find ), I just haven't decided what to use for the open end. By the way, perfect circles are easy with a router and circle jig. The truck bed liner sounds like a great idea, many layers would work well to deaden the sound... I am also planning to attach some rubber agitators the help stir up the action a bit, without beating up the stones. I'm not too worried about grit getting stuck in the liner as I intend to make one barrel for each stage. I will take pics as I go. I just have to wait for things to warm up a bit before I start... fresh fiberglass resin fumes are a bit too strong for indoors ( I do love the smell though, the wife dosen't ). This is what I have so far.... For now, keep the great ideas comming!!!! thanks, Chris p.s. Any good ideas on a motor? ( I know... that's a whole new thread ;D ), jk!!!!!

I read in a previous thread that Wally World sells the bed liner, though I haven't looked for it yet. I'll look for the rounds at Lowes; I was thinking that pipe strap along the edge might help keep the edge from getting beat up.
Sounds like Mark and Chris are off to a great start!

Nate- I checked out the bedliner material last night. It's $100 a gallon and I need very little. I think I'll check out local body shops to see if they will do the job reasonably. i may jst use the vinyl tool handle dip stuff and try it first as it hasn't got any aggrgate to create a rough surface and trap grit. The stuff is cheap, too- a pint at $7 would do. My motor is off eBay- a 1/12 HP continuous duty, internal fan cooled two speed motor with a 5/16" shaft. It has a base for mounting, too. It came with a double cog that was a B---- to get off- I had to saw it with my dremel-. I foung the Lortone QT12 motor pulley fit perfectly. i'm also using a QT12 bwlt and drive pulley which is bored to 1/2" and firts my drive roller (1/2" aluminum" perfectly. i got the Lortone parts from the Rock Shed, the only placre that had the motor puullety, and they had the best overall price.

I've read about the big tire tumblers and the problem seems to be that they wear out from the inside, since the inside wasn't designed for wear. If you do use the tire, you might consider coating the inside with something like Rhino-liner for that added wear resistance. In fact, I would recommend the Rhino-liner for any metal tumbler you use. Dampens the noise and improves the wear resistance.

Oops! I only read through page 2 before posting. I see somebody beat me to the punch with the Rhino-liner (truck bed liner). I undercoated my truck with some spray material that looked and felt just like truck bed liner. I picked a few cans of the stuff at the local auto repair store. It's been a few years but it was about $7 for a BIG spray can. Whatever you get, you want to be sure it has good wear-resistance, or it'll peel off on you with the first tumble.

Thanks for the tip on a cheaper source for the liner!

We thought it was cumbersome to have multiple barrels around...imagine 4 large truck tires
