[QUOTE="smalltruck, post: 1074844, member: 74125"] I also did the harbor freight tumbler a couple of years ago. My experience in a machine shop years ago with steel shot tumbling to clean parts made me a bit wary because this will always peen the parts from the media. So I went harbor freight for a couple of reasons. first I'm cheap and second the container size is smaller so less peening takes place. Make no mistake it will happen, my feeling was to limit it if possible. Keeping the mass in the tumbler down is key I believe. My recipe is about a pound of brass, pound of water and a pound of pins in hot water with Amorall car wash soap, and lemishine. What that works out to for me is 25~28 25-06 brass or about 40 .223 brass. I dry mine in a warm oven (use the warm feature do NOT go over 150 degrees) usually about 30 minutes. The most important part for me is tumble time. I never go over an hour to lessen the amount of tumble and peening that can take place. My opinion>>>If you have one of the large tumblers they work great but must be full to capacity or you will get peening and brass damage<<<My opinion [/QUOTE]
