Part Polishing Notes

Surface: Glass plate as a work surface — anything hard and flat works.

Backing: Leather, or thin foam.

Straight on the glass surface:

  • 320 grit (takes the longest)
  • 400 grit
  • 600 grit
  • 800 grit

On glass surface with foam under the sandpaper:

  • 1000 grit
  • 1500 grit
  • 2000 grit
  • 2500 grit

Worksharp: 6000 grit purple belt

Cordless Dremel: 14000 grit diamond compound

Notes: It'll start to look like a rainbow — seeing copper and nickel tones is normal.
