Re: Tumbler speeds

Oh, yes, this is a tank of a rotary tumbler.?

The base is either???or 3/8 steel. It was bent to shape, not cut and welded. They must have used a big ass press to do that.?

The rollers are specially designed for rotary tumblers and are not cylindrical. They have a curve that allows the jars to self-center and stabilize on the rollers. Really neat stuff.?

The whole thing is heavy as hell. Probably 100 pounds or really close to that.?

You know, when the Pharaohs died, they built a whole pyramid on top of themselves to keep grave robbers away. When I die, I will have them drop this tumbler on top of my casket and nobody will be able to rob my grave.?

??? ??? Sounds like? it was built to last . My first one , the one I built? I used? 2 3/4 rods with rubber hose I slid on in between 2 pillow blocks for each shaft mounted to a piece of thick? plywood? Then I found a old washing machine motor a 1725 RPM & & mounted that to the plywood , found some pulleys & a belt in a box , threw them on & got a new 1 gallon paint can . I pulled the bail mounts off the paint can & I had a tumbler , yea it still spins kinda fast but it served me well for many many years . Now a days much to my wifes dismay I have 4-5 others that were real deals , with one being one of the big Lyman vibratory units . I dont think I have more that $ 50.00 into the whole heard of them . 1 per caliber .

thanks

It has a single speed gearbox that I took off and put a belt with pulleys (that is all I had on hand).?

Last week I finally had the time (after 3 years) to clean out the gearbox and wash it off with Kerosene. Now, I just have to stick it back on and refill it with 90 weight oil.?

My tumbler came from some kind of printing facility. It was used to mill ink pigments into a fine powder before using them. It has an explosion proof motor on it.

It looked like a freaking rainbow when I got it. I wire brushed it, stripped the base with chemical stripper, repainted it with a silver color rattle can, and changed all 4 pillow bearings.?

It runs great now. After I put in the gearbox it will be again single speed. It will not make a difference for my brass.?

Now, if I were to try and use it as a ball mill, having multiple speeds would be great. Or, simply get jars that are of different diameters. The larger the jar diameter, the slower the tumbling speed.?

There is a formula for the ideal tumbling speed, can't remember it, but it ended up being around 200 rpm for my jar diameter.?

I'm just curious , were ya planing on changing pulleys or a variable speed motor ?

All of mine are just on/off , I never considered if I should be changing the speed of them . My first one the one I made does spin much faster than my store bought

( garage sale ) units .

thanks
