One of my many hobbies is building little projects. My latest project is a rotary tumbler for tumbling brass to reload. I'm using a 1/4hp motor I had laying around that is 1725rpm. 1-1/2" pulley on motor, 3-1/2" pulley on drive roller, 3/4" drive roller, turning a 15" OD drum with a calculated final RPM of 40rpms.
Video of my drive system:
Side pieces and bottom welded. Zero leaks.
My inside welds.
Welded up and sitting full of water. Overall I had two small leaks.
Plan for how the drum will roll.
