The following three videos are three years old though I haven’t changed a thing in my brass polishing methodology.
Step 1 – Tumbler and media
Step 2 – The mix
Step 3 – The finished product
Fill the tumbler bowl roughly half or just under full of lizard litter. Add 3 cap fulls of the polish. Let it run for 30-45 minutes with NO Brass in it. This coats the walnut with polish. If you add brass immediately skipping that initial mix time you’ll have brass filled with polish. You can imagine that you don’t want that. Add to your media a cool whip bowl quantity of dirty brass. Let the brass tumble 1-1.5 hours to clean it in preparation for de-priming/resizing. Brass is final polished after de-priming/resizing. This does 2 things. 1. It removes the resizing case lube your going to use. 2. It shines your cases to like new shine. This step can be 4-8 hours depending on the condition of the brass.
I prefer Lyman tumblers for three reasons. 1. Excellent customer reviews. 2. Lower cost. 3. They simply work well.
Lizard Litter of the crushed walnut variety is readily available at your local pet shop at substantially lower cost than commercially produced tumbling media.
I use NuFinish car polish from Walmart or the auto parts store. It’s relatively inexpensive and adds the polishing agents that crushed walnut lacks.
