If you glue caps on one end either use threaded plugs on other or expansion plugs. I would think threaded would be best but cleaning threads may be a chore.

Try using teflon tape on the threads. It would stop leaking and could possiably help minimize grit cleaning

To get the capacity you want you will need to use 6" PVC. Make sure the caps (which are pricey) have the same external diameter or the barrel will wander. on one end, if you can find a reducer to 4", you can use a plumber's test plug. I use two test plugs on a length of 4" PVC pipe and it works great. It fits onto my lortone 33B chassis, but I had to replace the huge wing nuts on either end withlock nuts as the wings would catch on the chassis and stall the barrel. Also, i found the barre3l would sometimes slip, and the problem was solves by placing a strip of adhesive rubber tape around the barrel near each end. I hacve tried to use screw on fittings but most have ribs around the perimeter of the cap that make for rough tumbling and the treads, teflon tape or not, still leak. Glue on fittings are the way to go. you may want to devise some sort of llifter for the inside of the barrels as PVC seems really slippery. i had tyrouble gluing pieces of 1/2" pipe cut lengthwise into my PVC barrel. They just wouldn't stick. I probably used the wrong glue, but no matter, the stones tumble fine in the small barrel.
Good luck!

I use 6 inch sewer pipe with a cap at one end and a 6 to 4 inch reducer on the other end. A 4 in. Qwik Cap goes right on the 4 inch end of the reducer. No tape is needed. Not counting the 10 foot sewer pipe, a barrel cost about 14 dollar to put together. The sewer pipe is about 8 dollars for a 10 ft. If you cut them 10 inch you will get a barrel for about 80 cent. You can cut them as long or short as you want. Counting PVC glue the wife says I got about 16 dollar in each barrel. They are running 24/7 and showing no wear. With about 18 lb of rock in them. I put cheap casters at the end of the axles to take care of any barrel drift. Can get a fist size rock in the barrels real easy if you want. It's the same barrel you see on e-bay. But about 1/5 the cost. Except I don't spray paint them. 6 inch cap 5 dollar 4x6 reducer 6 dollar 4 inch Qwik cap 3.50

When I was looking at making a set of tumbler barrels I decided to go the one time only or do it once do it right route so I got some hexagonal sections made up out of 2mm mild steel and put plywood ends on them. They have never given me a problem. They are used year round and the only down time is to renew the rubber lining and seals every couple of years . The only issue is that they are not big enough . However, getting round that with a monster barrel for the rough grind. Will hold about 110-120 pound of material ;D. Its just about finished and will post the pics when I get done so all can see. Probably will cost about $200 all up by the time I finish. Cheers Scott

I have given up on screw in PVC caps. They just can't be sealed easily, and according to a plumber friend, aren't intended to. Be careful to make sure the end cap and reducer are the same thickness or you'll have big time drift. Also, some end caps and reducers have little ridges around the edges lthat act like little speed bumps in use. I guess they could be ground off. A 4" test plug (preferrably plastic) might make a really good, watertight end cap. I use them with 4" sewer pipe and they work great. They cost little more than a quick cap. Scott, just how do you seal / line your bbarrels? WHere do you get the rubber, what kind of glue do you use, etc. ? I have a monster MDF and wood barrel with octagonal sides I made but cant's seem to get a good seal on. I have used Plasti-dip, Bedliner compound, silicone sealer, and waterproofed the interior first with shellac based primer. Still it leaks!!!

A 6 inch PVC pipe sch 40, 6 1/2 inches long with those quik caps on each end makes a good 10 lb barrel. Don"t use the stainless steal bands. This works well for me. Thet are also called test caps. James
