A while back there was a thread asking for pictures of home-built rotary tumblers. I was busy with harvest then, but now that winter has set in here in Illinois, I decided to post some pictures of my project.
I started with a junk self-propelled lawn mower. I used the gearbox, axles, wheels, belt, and drive gears. I cut & shortened the long axle so both wheels would ride against a 5 gallon bucket. The motor & pulley were also refugees of the scrap pile. I couldn't get enough traction between the bucket & wheels, so I had to add a press wheel on top. I had a pile of used spring teeth from the harrow on the seed drill, and they make fantastic tensioners. The other half is what's tensioning the drive belt. The base is an old disc blade. The pictures are pretty self explanatory. The lid on the bucket is what's known as a "Gamma Seal". A friend at work showed them to me, and it works quite well, although If I don't get it tight enough, it can unscrew itself and dump my media all over the floor.
It works fairly well. Total investment including media, gas, wire, electricity, and NuFinish was about $10. I polished 900 45ACP cases to a nice shine in about 4 hours, and I suspect it could have handled more casings, but that was all I had.
