I retired this barrel. It was too heavy for me. Anyway, it is made of 8 inch PVC and 2 feet long. Barrel heavy empty. Couplings plus 8 inch sch 40 pipe, over an inch thick except at small joint in middle. Plus the 4 inch opening was slow to unload thru whilst holding the monster. The weight of it rippled the rubber hose on the shaft so I removed it and put a large o-ring on the end pulleys to drive both shafts uncovered. Little 1/6 HP 700 RPM commercial A/C fan motor ran it fine at 26 RPM. May not have enough HP to spin such a large barrel at 40 or 50 RPM. Faster does take more horsepower. Unfortunately, fan motors come in 1/6 and 1/8 HP @ 700,1000, 1125 RPM set ups. Perfect energy saving fractional horse powers and lower RPM's making efficient single reduction easier. The 700 RPM motor is rare in 110VAC set up. High end motor with large capacitor attached in metal shell on top of motor. Lower RPM means more torque, perfect for tumbling. Lower RPM quieter too, everything rotates slower in the drive train. I will get the info off the name plate and get a quote for it's cost. Best motor I could find so far. And long tested with 60 pound capacity. Note 5 gallon bucket of SiC 30/60 close by LOL. This rig had a big appetite. Note grease fittings on all 4 pillar blocks AND single end roller, tumbler sloped to right to force barrel to ride on it. Shaft spacing is for a 6 inch PVC barrel, but worked fine for the larger 8 inch barrel. Shafts are overkill at 1 inch, but were laying around in the bone yard so that is what was used.
