MAKING THE SANDING BLOCKS
FLAT To hold the paper flat, I use 3 or 4 blocks of wood that measure 1 1/4" x 2 1/2" and have a piece of 1/16" rubber or cork glued to one side. It cushions the paper, so it does not wear out as quickly.

configuration. At the local hardware or box store I buy plastic tubing in 3/16", 1/4", 3/8" 7/16" and 1/2" OD. I then purchase steel rods that fit tightly inside the tubing and cut them to 3" lengths. This provides a firm radius block for polishing curved areas.

SANDPAPER PREPARATION The actual polishing of the metal is accomplished by using various grades of wet or dry sandpaper. There are several different makers of sandpaper, but I use either 3M ® or Norton ® brands. The grades that you should have on hand are 120, 220, 240, 320, 400, and 600. These come in 8 1/2" x 11" sheets. I start by folding the sheets and cutting them in half until there are 16 pieces 2 1/8" x 2 3/4". It is important to cut the paper with scissors because tearing the paper will leave coarser edges than the grit of paper that you are cutting into smaller pieces.
