What you thinking foozer..................SS balls, or Mix? What size?
foozer:
Im thinking SS balls (dry) probably in the 1/8 inch range just for a debur operation. Really like how the BB's clean the edges up. Nice even radius. Grab a tube of daisys (real cheap) and toss a sharp edged piece in. The SS balls should hold up for repeat usage.
For finish I'm leaning towards walnut shell and Simichrome. No reason other than when this thread first started I thunk to myself, sounds interesting, next day I had to go check out a rental that the tenants moved out of and there it was, a 20 pound bag of walnut shell cage litter. OK that works. The in between steps? Im watching you :) Did I mention grit is messy!
The in-between stage is one of them dependant upon the finish being presented. Want to remove as little material as possible and still get rid of any tool marks.
Still watching how the 220 grit is doing against the scratch mark I put in the piece. When the piece is all frosted over Ill switch to the 500 grit just for shits and giggles. I am not going to use Grit for future use, Did I mention grit is messy? but some equivalent product has yet to be looked at. Like most things, Ill put the choices up on the wall and throw a dart to see one is best.

The shell and cob media in my splined test pieces is a mess. I'm going to get some burnishing compound they have, is nice to only buy a few oz., instead of a 5gal pail through mc carr.
Is burnishing and polishing the same thing??
I am happy with the ceramic media results. I like the way it deburrs the pieces. Still not getting the shine from the dry media that that guy's video with the SS balls. I don't know yet, but think the dry media may be the way to go when the brass trials start.
I wonder what kinda of "volume" a pound or ten pounds of the stainless steel media is?
10 lbs of ceramic is about 1 gal
6 to 7lbs of shell/cob is bout 1 gal
???lbs of SS is about 1gal
foozer:
1 cup of BB's, steel, is just about 2 pounds, there 4.5 mm or so the container says. I dislike metric just cant visualise it.
I think burnish is a straight metal to metal contact and polishing has some fine abrasive additive. If left long enough the dry SS should give a nice shiny. Plan of attack so far is just to use the balls for smoothing off the sharp edges and switch over to the finish process.
Been a couple of suggestions made so far as to use of a final, similar products designed to carry a polish compound. Trick is to settle on one that will do the job in a reasonable time frame (subjective of course), holds up to repeated use, and that wont break the bank in the process. Can't have Prime Rib on a burger budget and maintain this nice round figure. Crap now I'm hungry again.
