hello. i am attempting to polish some stainless steel moulds. i am using a 2850rpm bench grinder, 6" sisal & loose cotton wheels with black & green compounds.
i have been reading this site extensively but i have some questions too. i notice in the "pick a buff" link on the main page, this information is listed to polish stainless.
Quote:
1st Stage - Rough Cut To Remove Scratches
Use Sisal Wheel With Emery (Black) Compound
2nd Stage - Final Cut and Initial Polish
Use Spiral Sewn Wheel With Stainless Steel (Green) Compound
3rd Stage - Final Polish (or Luster)
Use Spiral Sewn Wheel With Stainless Steel (Green) Compound

what do you do different in the 2nd stage, as opposed to the 3rd stage. is it just the direction that you apply the workpiece against the wheel (cut/colour motion??
so far the way i have done it is to hit the piece with 400,800 & 1200, then buff with sisal/black and polish with loose cotton/green. what could i be doing to improve my results.
