Everything looks good so being as I'm cutting brass I only need to make one pass so I go to the full depth, y reading, and start my passes. My procedure is this: make my cut, disengage the handle pin and rotated 1 revolution plus the 21 holes on my quadrant spacing, rotate quadrant until it's up against the pin and then make the next cut. On a gear with large teeth like this it's not hard to tell where you're at but with fine pitch teeth and a great number of them you have to remember to be consistent with moving the quadrant every time.
