Worm Gear Tool
In order for Periodic Error Correction (PEC) to work through EQMOD, the worm gear has to be in the same place every time the mount is started an unparked. Using the flat surface on the worm gear axle, I line it up parallel with the edge of the housing. Using this L-shaped tool gives me a longer lever arm for improved accuracy.
