I can't find the discussion on modifications to the Thumler Tumbler to optimize cleaning with the stainless steel media. I recently tried it and my drum leaked. Thanks for any help.
I have made no modifications to mine at all. Just add water, lemishine, SS media and brass. Mine has never leaked enough to notice, and I have forgotten it overnight before. You are using the rubber piece between the metal lid right?
I use SS media, lemishine, and dawn and it works better than I could ever hope for with no leaks. If you're having that problem, I'd just repair it with some rubber sealant.
