I have a lortone 4lbs tumbler that I've had to re-engineer a few times to keep it running and it works fine for a few dozen pieces, about a coffee cup and a half.
I've been wanting to build a larger ss tumbler to hold a few hundred pieces of pistol and at least 100pcs of rifle brass at a time.
Lo and behold, we stopped at a garage sale and I found 3 lortone tumbler 12lbs drums for $2ea, and ended up with all 3 :mrgreen:
They've set around for about a month now while I was trying to figure out how and what to build and to make it work with this motor that I have.
I don't know what this motor came off of, or where it came from. I've had it for about 15 years, and it's been used for all kinds of tumblers and was used to power an old Chevy rear end that my dad had mounted to the back of an engine hoist to make a power hoist.
I've tried to guess how much torque it has, to no avail. We built a 1/4" steel plate mount for it and put a torque wrench on the shaft with a cheater pipe and we couldn't hold on to it.
Anyways, I decided that if I was going to build this, it was going to be built around this motor, just because it lacks nothing, powerwise.
So, the motor has a 3/4" square output shaft and I didn't want to use any pulleys. Direct drive 8-)
I found a homemade tool of some sort that had a piece of 3/4" square on one end and 5/8" on the other, so I chopped it down for what I needed to connect the motor to the cradle.
To keep it close to 1:1 gear ratio, I used 4 old pushmower wheels mounted on a piece of 1/2" allthread, and used a piece of metal with another bolt through it and in the spokes of the wheels to make sure they spin.
The freespinning shaft is 4 other old mower wheels on a piece of 1/2" barstock and they rest on the 2x4 wood with no bearings.
The bearings for the driveshaft are actually skate bearings with a 12mm i.d. and roughly 1 1/8" o.d. I spun the allthread around on the bench grinder to take a hair of so the 12mm bearings would fit the 1/2" allthread and smooshed it all together.
A small 'L' bracket over each bearing hanging on the 2x6 holds the bearings in place.
I do have to tweak the bracket that holds the lid nut, it tries to let the drum climb out of the bracket, not devastating, just annoying, it needs to be about 1/8" deeper.
All in all, not too terrible, I did get tired of painting though, eventually I'll finish it.
Total cost, $2 for the bearings, everything else is just scrap material and other junk laying around the house
