• Shed barrel polishing update.
  • Shed #1 was hand polished by Bubba with 320 grit sandpaper, then put into the barrel polisher for ~ 1 hr with corncob. Shed #2 was utilized just as a counterweight immersed in corncob and straight out of the machine shop with no further surface treatment. The results: Shed 1 comes out looking as if it were DPP, shed #2 comes out mirror finish, but the machining markings can still be seen, and the polishing scratches (inherent to the corncob / polishing media) are more easily seen.
  • So, the procedure so far: polish with 320 grit sand paper, then ~ 1 hr in the barrel polisher with corncob.
  • Next, Try cones instead of 320g grit sand paper.
