Picked it up today, I think I am going to convert it from the drum to a driven shaft and and idler to run my barrels on. Paid less than the cost of one of the pulleys. Bonus - the motor just got cleaned up and wired....works well. The drum holds approx. 5 lbs per chamber. Do you think homemade or vintage commercially made? Pretty well done in an overkill kinda way. 1.5 to 8 - 3 times at 1750rpm (18 RPM?). Finger Eater Inc. ?

Looks like a commercial parts deburring tumbler for tossing machined metal parts into.

I agree with Chuck. A parts deburring/washing station.

It does not hurt to give it a try.
Things to look out for: 1) What RPM is it running at? This can be adjusted with pulley and belt changes. 2) The shape of the barrels. Will it be too aggressive and cause damage to the rocks? 3) Because there is no database of people using that for rocks you will be have to figure out all of the specifics as you go. 4) Are the barrels lined or are they steel inside? Noise could be an issue.

Chuck, I am now sure I will not be using the drum at all, it is unlined, badly sealed and would be incredibly loud to have in my shop. My calculations put the 3/4 shaft speed that the drum is welded to at either 18 RPM or 7.6 RPM. I turned down the ends of a shaft to 3/4 last night and will replace the drum with just a shaft. An idler shaft will be mounted parallel to it and should run my 12 lbs drums nicely on it. All the pulley bearings are tight and were removed and cleaned, reassembly when my new bearings for the idler shaft arrive. Using my existing drums will take the guesswork out of the specifics as long as the RPM's stay close. I use Thumler's rubber drums now, I like them and they have served me well over the years. Rads
