Well, I took the advice (mostly) and went to Harbor freight and purchased the 5# vibrator tumbler for $55 and 25 lbs of fine walnut media for $24. Then to Wal-Mart for the Nu-Finish for $7.50. I had some old 38 spl brass that was military ball from 1966 that was super dark and dull.
I put 2 1/2 lbs of the walnut and one cap of Nu-Finish and 1/2 drier towel. I ran it 10 minutes then added 250 rounds of the old brass. I checked it after 2 hours and it looked really bright and clean. I decided to let it go for 2 more hours to see what would happen. 4 Hours total and I really couldn't see much improvement over the first 2 hours. It really shines!
I removed the brass and shook it out over a bucket with a large strainer and then packaged it.
I added 1/2 cap of Nu-Finish and 1/2 cap of mineral spirits and after operating for 5 minutes I added another 250 rounds of brass.
Thanks for all of the advice. Y'all are great!
