Tumbler Trials & Tribulations
1hand:
SS pins showed up today. I like the looks of them. Next time I try them for the deburring step, I'm going to start with the SS pins instead of the ceramic. Hopefully will keep the parts cleaner, and just knock off the edge a bit. If that works it should be an easier task to return the parts to the orginal sheen with the SS balls.

Just checked the Shot again, and they are starting to transform. About a 1/3 of the way to the finish line. Total time so far 24 hours.

Trying some walnut shells in my vibratory tumbler for the final finish. I had some 'creamy' car polish that I tried to mix in with the shells, but it wouldn't mix and looked like a cat's litter box. I added some water, mixed it up, let it dry but the results were unimpressing. So, I went to the local auto supply and picked up a 10 oz. bottle of Autosol Metal Liquid Polish. I poured about half the bottle into about 3# of shells and mixed it together by hand. The polish disappeared instanly, I guess soaking into the shells. I left it overnight then ran some parts in it today. After about 4 hours I pulled the 6061 aluminum parts out and....yes! They were shiny. Not enough to see your reflection in, but a very nice finish. Tomorow I am going to pour the rest of the polish in and let it run some more. I will get some pics when it's done.
I am wondering about the 'treated' walnut shell and corn cob that is sold. Basically I'm wondering how they 'treat' it. The treated shells from Rio are mucho expensive.
Perhaps I'll try a google search.
foozer:
Keep us posted on your results. Ken gets good results with treated shells, have read where shells and simichome polish work and then just plain dry shells. Again, the theme for a final finish is leaning towards walnut shells.
