I did some more searching last night on burnishing compounds. Lot of guys using Dawn dish soap. Some say no difference, some say there is a better shine using a regular burnishing compound. I ordered the 5/32" SS shot and some of the the dry compound to try.

Have done some hand burnishing, the pushing the clad back over minor AP skin scratches, miserable process. Just used Vaseline as a lubricant. Idea was to smooth the metal without removing any. So the soap, ya I can see it. Pure AL is so soft that a dry rub creates enough heat to mar the surface. The lub should allow the material to smooth without an actual metal to metal contact.
Me thinks I'm over-thinking it when it should be a Yup That works

That hexagonal tumbler looks good. What stops the tumbler sides from abrading and becoming opaque ?.

I haven't had a chance to use it yet, but I imagine it won't take long before the sides become hard to see through. The middle part of the ends should remain clear.

Well I can report upon one thing not to do. Using Grit, something that when this experiment is over, will not be using again. Brain Fart, why not just add some good old WD40 into the dry grit mix, what can it hurt. Took a while to notice that the "Thump, Thump" noise was gone. Opened the tumbler and the grit WD40 mix had turned into something akin to baby POO!
Took a while to clean it up, Did I mention that grit was messy!!!

Tracking shows my Rio order will be here friday. The next run of parts Is going to be the real deal. I need to get my wrist parts done, to meet with a potential distributor. :whip:
Next round will be the 1" stub shafts with the splines and tapped set screw holes. I going to start off with a mix of medium and fine ceramic for deburring in the rotary, then the 1/8" Needles SS in the rotary to start the polish, and finish up in the vibratory with the 5/32 SS shot. :bow:
I'm going to run my 5 extra parts first to fine tune any problems, and cross our fingers for the production batch. :palm:
