Here Bob demonstrates grinding a saw cut piece of glass from the rough grind at the electroplated diamond disk 60 grit, through a 140 grit and 270 grit, to the resin diamond smoothing pad for the pre-polish and finally the LP66 pad with cerium for the final polish. Along the way, he'll give some helpful hints and tricks for using your horizontal lapping wheel and diamond disks to their utmost efficiency.
