Re: Ultrasonic vs Stainless tumbling?
I'm not sure how they compare to stainless because I have not done that type yet. But I recently bought the Harbor Freight unit (identical as the lyman) and it works pretty good. Takes some time to clean them but it has left the cases clean inside and out like a mirror. I've tried several different solutions, a vinegar mix that didn't do anything really for me and the mix by lyman that is just citric acid.
I like the Unit itself because it heats the solution and can hold quite a bit of cases. The only thing I can recommend is get the basket from lyman that Goes in it because there is a plastic tray that's really useless with the HF model. I will upload some pics later of some brass I did.
