The metal parts look like they have come up great. What's your method for polishing/regraining?
I use my Tumber for the metal pieces and Green Scotchbrite or 180 Grit Wet/Dry sandpaper to regrain the metal guides.
Great thread and great job!! Inspirational!
Do you use the corn cob media that generally comes with the tumbler or something else? Do they come out of the tumbler like your pic's, or is there another step to get them shinning like that?
Reason I ask is that they look that good its like they have been re-chromed, if that's how they come out of the tumbler I cant wait to start using mine!
