With winter on its way I have been trying to come up with a way to make a quiet tumbler barrel for use in the house. The idea I came up with was to take a 9" section of 4" abs pipe and glue a layer of rubber gasket material on the inside with contact cement. I sealed the joint with rubberized sealent. I then made 2 - 1/2" thick circles out of plywood, and 2 circles of rubber gasket material. All circles the same diameter as the abs pipe. These I attached to the ends with screws.
I'm letting the sealent cure overnight then tommorow I'll start a batch and let every one know how it works.

And now you will be able to answer these questions for us... 1) Is 4" diameter to small? 2) Do you need mixing blades on the inside? 3) Will the gasket material hold up to the abrasion? 4) Will the end seals leak? If you can get this to work (even on the finer grits), this would make for very cheap barrels for all the different grits. Impatiently waiting for updates , Dr Joe .

Nothing I like better than kibitzing. Hardware stores around here sell 12' of foam pipe insulation for 4" pipes at $4.29. Add a few wraps of duct tape for durability and that should also help reduce the noise. Hmm...I guess you'ld have to modify your roller width as well.

I made some barrels about the same size, but I quickly outgrew them and wanted bigger. I put PVC lifters (mixing blades) in mine, but I did not line the barrels.
You can use a test plug for sealing one end.
You can also make a sandwich of wood, gasket, wood on the other end. One piece of wood goes inside the pipe and is sacrificial, but keeps your gasket from being abraded. (I did this on my 50lb barrel.)
If you don't use a test plug to seal the end, but use the sandwich instead, you can use threaded rod (or bolts) to help pull the seals tight and provide lifters.
I don't think it would roll on the pipe insulation. If it did, the insulation would wear out quickly. If you built bigger end caps and put those on the rollers then the insulation could very well absorb some of the noise.
Hope this helps, Chuck

Ok here are some answers drjo.
1- 4" works pretty good, I have an unlined 4" one with test plugs that works great but is so loud.
2- I have never put in mixing blades, still get shiny rocks.
3- Its rubber gasket material about 3/16" thick so we will see
4- not so far but I'll let you know
So far its going and is as quiet as a store bought barrel. I'll update if anything happens and put some pics after about a week.

4'x8' sheet of foil back 1.5" insulation foam, Sheeting. Build a box about 7" from all side`s and a 2" vent on top and on one side to allow air to move through the cover. This should cut down on the noise a lot.

I've done the foam box thing it definantly helped with noise but still a little louder than I would like for the house.
Still leak free and quiet this morning.

I'd love to see some pictures on pre, during and post construction if/when you get a chance! Sounds like a terrific idea to have one or two barrels for each grit at a fraction of the cost.

I just can't win. Went away for the weekend and the motor went on my tumbler. I opened up the barrel though and all looks good so far. Its a little hard to tell with the rock and grit in there though. I will try to get some pics tommorrow, then find a new motor.
Its a homebuilt setup Joe.

Seems tumblers are like dogs... you can leave them all day as long as you come back at night... leave for what they perceive as too long and all and all is lost!
Sorry about the motor, at least the rocks didn't spoil ;D.

Hi Scott,
I was going to say build a box round it with baffles over the air vents but it has already been said,
I used to line 9"Paint tins with a stiff rubber (3/16th" thick) used on the floors of Horse boxes ( used for Transporting horses to races) and stick it in place with silicon or a "no nails" building trade adesive
This worked well but its a good idea to have a dedicated barrell for each stage (stop contamination)
Hope you get the mortor sorted I use old Central Heating boiler fan/fuel pump motors , they got a good torque and last well

What kind of rubber gasket is that? It looks like it's time for a trip to Lowes for me!

Actually its sched 40 Joe. The gasket material I glued in is about 1/4" thick and black so its a bit hard to see the join.
It is neoprene gasket material. Still don't have it going yet though, I've been working a lot of late days so everything is closed when I get off work. I'll get a motor eventually though. Then I'll let everyone know how it does longer term.

I finally got off work early enough to go get a motor. The local heating/AC place gave me my choice of any motor I wanted to take out of the scrap furnaces so I'm back up and running. Should know next week if the quiet barrel idea works.
