Just talked to Frankford Arsenal about replacement parts for their rotary tumbler. Very upfront about their product. No parts will be sold for repairing and they have no plans to take back and rebuild units after the warranty expires. They do state that within a reasonable time, if a unit seems to have failed from normal use (not commercial), they would probably make an adjustment on a case by case basis. The gears are plastic and they say the unit only pulls 1.5 amps when running. The unit is expected to last many years and they seem proud of it's exceptance by the shooting public. Mine has done several thousand case and I'm very satisfied with it so far. I do wish it came with 7.5 lbs. of pins instead of 5 lbs. , but it cleans extremely well. Their cleaning chemical does work better than dawn for me so I am going to order some. Still $159.95 and free shipping from Amazon and includes pins. Rod
