Re: [TCML] Polishing Metal (ie Brass) after machining . . .

[bunnykiller <bunnikillr@xxxxxxx>]

the easiest way is to have it done professionally, but thats pricey.
Depending on your finish after machining, ( worst case senerio) sand 
surface with 220 grit then 400, then 800, then 1500 ( emory cloth types, 
normally a cloth backed material). Next step, go to a polishing "rouge" 
( a reddish paste stick, can be found in better automotive stores) 
applied to a cotton buffer wheel. After that has been completed, use a 
polishing paste like SemiChrome or Flitz ( supposedely they run in the 
8-10 thousand grit size) to get the "mirror" finish. I prefer to apply a 
wax as a final ( carnuba) touch, helps deter tarnishing for a few months.

BTW  use light pressure with the buffer wheel, a heavy hand can lead to 
"lumping" of the material being polished.
