Thread: Case Tumbler

Question for those who have made a tumbler:

Does a regular bucket with lid work, or do you need to glue some sort of "paddles" to the inside to ensure the brass actually "tumbles" rather than just sliding around and staying at the lowest point. Visualise the inside of a clothes dryer.

Some commercial case tumblers are hexagonal, so the brass travels up the side then tumbles back down during rotation.

From the looks of things we will probably need to glue in a few paddles.

I use one of these , have a nice shape inside that tumble the brass well, good screw top lid and can get them from local recycling centres for next to nothing

specweapon:

I don't know of any recycling centres near where I live, so to help me locate such containers could you please tell me what these containers are made for, what size they are, and what they are called?

Thanks in advance

I made ine from a 1ltr Coffee tin and glued/riveted some paddles to agitate the brass.

I reckon a big container of protein shake stuff would work well. My tin works well, but theres a lip on it which makes it hard to get all the pins out.

Sorted...Mazda power! Wood base used as a mock up for sizing. Metal frame to come.

Works a treat.

How much current does your wiper motor pull? Any ideas?

Keen to have a go at this

Not sure. I'm thinking of making another on out of an old multi function printer as well

Very clever thinking. Awesome.

Thanks for the info, Moutere.

I found some of those Coleman containers - new - in an 'outdoors' shop today. However, at the price of them, I doubt that too many people would be just using them a couple of times and then chucking them out in the recycling.

Not sure how easy or otherwise it would be to attach paddles inside them with water-tight fastenings. (I'm looking at making a 'wet' tumbler) But I'll keep them in mind.

Sad news, I have succumbed to an off the shelf 5kg tumber

150mm PVC pipe, capped one end, screw cap on the other. PVC cement a couple of lengths of conduit (PVC conduit of course) on the inside to help the contents tumble, rather than slide. Watertight, works a treat


This was the cheapest I found:

Kontiki coulper with thread rubber seal cap-150mm | Trade Me It has a big rubber O ring on the inside, I run a little dishwash on it before I screw it up, helps make a good tight seal, and also helps release it when it's done

..and a 150mm 'push on' cap from the same place. I have a length of plain 150mm pipe ( to go between the fittings, only need 80mm so not worth buying a meter..), and a meter of the conduit you can pinch if you're in Auckland. PVC cement from the Warehouse is a couple of bucks.

Total cost around $50 and it's bullet proof.

any particular reason why Greenie? Looked like you were on to something there, just wondering why you ended up buying one.

Cheers
