There are now adhesives that will glue HDPE; but they are quite expensive. Using this material there are several ready made products that could be adapted to rotary tumbler barrels using goodies from Lowes or Home Depot. Namely the 2 gallon buckets made from HDPE and the ABS sewer couplings with rubber doormats on the inside as sound reducers and reinforcing. Has anyone found a 'low cost' adhesive that will work. So far Loctite 401 and Loctite 3030 will work but at $18+ the cost of doing this negates purchase of readymade barrels.  |

I'm not sure how "low-cost" they will be, but I'd head on over to the auto parts store and take a look at their adhesives. 3M makes a spray adhesive for bonding car headliners that will bond polyethylenes. I know there are others, but my memory fails me at the moment on the brand. I'd definitely prefer to work with a spray adhesive over a loctite type adhesive in an application like this.

Rite now I've got a lot of agate and some pieces are quite large. Needing larger barrels. Made up home made drive that will handle about anything I'll need. On one of the drive rod assemblies I now have set up for 8 - 10" barrels. For now using Kroger coffee (32 oz) containers (HDPE) sealed with good ol' quack-quack tape. Do a great job but won't last much over a week with the sharp agate. Have used 5 gal. buckets (HDPE) in past but just a little too noisy and large for my needs.
The 2 gal. buckets (HDPE) at Home Depot are just the right size. Using one bucket, with 4 lids, two 'glued' to the bottom to bring base diameter up to lid diameter. One 'glued' to bucket at lid with another lid glued to that and then take the ABS 4" sewer fittings from Home Depot glued to center of those lids with PipeConX cap to close and access. Using more glue, steal my wife's black rubber 'wecome mat' from the front door, cut it down and this will quiet the noise down along with extend the life of the HDPE bucket. (she hasn't noticed my 'temporary' use of her treading machine with the 5 gal. bucket as yet.) snic

Scooping the grit and mud out of that truck tire is not easy. Ask DesertDweller. Cant really dump the contents out. Have to scoop, and then take the tire outside and hose it out.
Why not use epoxy to glue in rubber gasket material. You just want it not to seperate from the side of the barrel. You don't need a lot of shear strenght.

An epoxy outta work. I was wondering if PVC cement might hold it... I'll have to read the can tomorrow.
Just a suggestion, whatever you end up using, you might want to do a dry (wet!) run to test it out. Throw in the rocks and water and see if it holds. That way you don't waste a bunch of grit if something comes off.
