Made out of 6 inch schedule 40 PVC. The are about 18 inches long and hold 15 pounds. I have two that i run hard silicified coral in at fast (60RPM) speeds and slow(20RPM) speeds for finish/polish. now for almost 3 years. 24 hours a day. My store bought barrels did not last long at these speeds. I have recently had to patch them. And am building this new barrel w/simple preventative measures. The main components are 2-6" sch 40 couplings------2 x 7.65=15.30 2-6" x 4" sch 40 bushings--2 x 15.11=30.22 Section of 6" sch 40 PVC pipe as long as you want your barrel 4" section of sch 40 PVC pipe for access hole 4" Fernco rubber cap to cover access hole---6.00 4" to 2" sch 40 PVC bushing to plug closed side of barrel---6.89 Big can of PVC cement 16 oz---7.00 So rough cost not including pipe is less than $75. Not cheap but totally rough and tumble barrel. The easy reliable access hole is way user friendly. The bushings on the ends provide thick plastic ends where barrels wear out typically. The open end w/Fernco rubber cap for easy access: The closed end has a bushing due to the bushing's rugged thickness. If you use the simple and obvious end cap route it will wear thin in the center: I still have to plug the 2 inch hole in the 4" x 2" reducer bushing on the closed end. I want that closure flat so another barrel can run against it without damage:

That is a lazy man's project JIm. And the concept i copied. Just used heavier(sch 40) stuff).
By the time i get in to the 8 nuts that hold the store bought barrel this one is about built.
Not to mention a screw driver on one band clamp to access my tumbles. I am lazy Jim. I am sooo lazy.

I get what he says about working his ass off to stay lazy! (Yeah, me too!)

You can get 6" P.V.C. at Lowes? Here, 4" is as big as they go. 6" is a 58 mile round trip for me.

It is deceptive Jean. I will work hard. But i built w/brick,steel,metal roofing,aluminum windows and copper gutters. So it is almost zero maintenance. My tumblers have 1.5 inch solid shafts with industrial pillar blocks and grease fittings. Twin capacitor GE motor. B size V-belts. My nursery has a lot of concrete for low maintenance. All my equipment is simple bulletproof stuff and most is 25 years old. So i know it like the back of my hand. Spare parts ready. Everything i do i use the best stuff. It is so much cheaper in the long run. I have lived here 25 years. And i built everything to last starting a long time ago. Contractors and part time help-same guys for 10-20 years. Some show up and fix stuff w/out me calling them. 2 trucks in 25 years. But i did extreme maintenance on them. They get sold at 300,000. I was into that big cast iron lapper you bought about 6 months ago. My kind of machine. Or that weigh scales you got recently. That thing is a hoss. I am in need of a newer model wife. The one i got has worn me out haha.

We have 6" sch 40 and 6" drainage(SDR 35) at our Lowes Larry. Not at Home Depot though. I live 8 miles away from the giant industrial district of Atlanta and can get anything up there. But Lowes beat the industrial warehouses because i only buy small lots probably. Home Depot carries 8" and maybe bigger on the web.

I was into that big cast iron lapper you bought about 6 months ago. My kind of machine. Or that weigh scales you got recently. Cleaned up the rociprolap, but have yet to make use of it. It is still sitting on my patio. I was thinking something like that could be useful for settling rock snot in saw oil? Along the same lines (shaking down) I've got a friend in the prospectors club that will bring home buckets of dirt (hopefully with some gold in them!) to pan out. But instead of panning all of it, he would add water and shake it down so the gold goes to the bottom. Could work for that? Then all he has to pan is just the bottom of the bucket. Now that's working smarter.

I use a good bit of motor oil. I store it in 35 gallon drum. Call the recycler every 3 years or so to pick it up.
It is crystal clear after so long from settling. I mix it with kerosene in the rock saw.
Vibratory separators are great for such. They got to be tuned for the app though. Like never overload a vib tumbler or you may burn the motor up.

Great setup! This pretty much draws the line between wanting to tumble rocks and wanting to TUMBLE rocks.

You can get 6" P.V.C. at Lowes? Here, 4" is as big as they go. 6" is a 58 mile round trip for me. check out companies that do wells and septic systems, and some plumbing companies, as they may have smaller sections that they will sell. (they keep them around so as not to cut a full length for a 3 foot piece.) There is a company near me that does a lot of pipe work with sch40 pipe and they have it up to 8 inch in diameter and will sell short pieces if you want one. they keep pieces from 2 - 6 feet in stacks for use as needed. I love this project and plan to build a smaller version 2 wide x 1 deep so I can stack a 3rd on top if needed. something small I can keep outside my shed in the back yard.

That barrel is heavy. It weighs 13 pounds empty. Add 16 pounds of rock. So about 30 pounds is a chunk.

Please share photos of that build Mario.
You are bang on about the pipe sections at grading and plumbing companies.
I run those so hard and fast i appreciate their reliability. Tumbling is hard on stuff.

Dad_Ohs, that 58 mile round trip is it to get bigger than 4". Put a bunch of miles on the phone before the car. Thanks though. Larry

It can wear thin between the couplings. At the center it is only as thick as the pipe. I notice the light shines thru that area meaning it is getting thin. So i put a sleeve inside. Check out the inner pipe that was split down the length and reduced to fit inside the pipe section so that there will be 2 pipe thicknesses at the thin part between the couplings. This is the closed end that wears thru. This time it is way thicker by using a series of bushings.

This barrel is almost 3 years old. Running a lot of highly abrasive material.Larger pieces hard and fast. You can see the section between the couplings wearing thin. That is where it is the thickness of a pipe.
