thingiverse

Place one hole over the spindle and rotate the platter until the long tonearm sight line points directly at the tonearm's pivot in the horizontal plane. If necessary, secure the platter with masking tape. Move the cartridge backwards or forwards until the stylus sits exactly on the center of the small cross in figure N. Rotate the cartridge to align the cantilever with the grid.
