I was inspired by a thread on another forum about home built tumblers, and needed one for deburring Sight Mount and doing brass; here is my finished attempt. I had a motor, and the framing material, bought pillow blocks and pulleys as well as a Lortone 12 pound drum that was being cleared out. I have a little over 100 dollars in it including the new drum compared to the 250 - 300 for a new one in this weight class. It is very quiet and is turning the drum at 68 RPM. Clean inside case, clean primer pocket, clean flash hole. I can easily do 3 -4 pounds of brass or sights in this set up. The silver thing at 3 o'clock is the magnet I was using to pick up stray SS pin media. I am happy.
