Rocky Mods
2 X 1/4"-20 nylock nuts. 1 X 1/4"-20 wing nut. 4 X medium "3M Command Adhesive strips". 1 X wooden wedge to block the factory adjustment button open. It takes about 2-1/2 turns of the screw to go one notch on the Rocky. Assuming that it is easy to judge an 1/8 turn, I have increased the resolution of the grinder by 20 times.
