Love my Thumler tumbler. After 1 year of use, I removed the rubber liner and found some rust in the steel container. Will remove the rust, prime, and paint and plan on removing the liner after each use. Some sort of lube to help make the liner removal
on the rubber bin would be a nice touch.
I use ss pins, cheap dish detergent, and ascorbic acid and brass, primer pocket are as new after 1 - 2 hours. Quiet, and no electric shaver sound running for hours....
