Garnet Commutator Paper

larger image
For proper seating of your Helwig Carbon brushes, use Garnet Commutator Paper. It's non-conductive and is used for pre-shaping new copper and carbon brushes and for cleaning and burnishing commutator surfaces.

To pre-shape brushes, commutator paper of sufficient width to contact all brushes is secured, abrasive side out, to the full commutator circumference with masking tape. With the new brushes in place, the commutator is rotated by hand until the brushes have taken on the radius of the commutator. 80 grit paper does the primary shaping and should be followed by 220 grit for a fine finish.

Surface burnishing of the commutator should be done with 150 grit followed by 220 grit.
