I believe Fred (SSS) was referring to the locking lug lead in ramps, not the cocking cam.
BillAnother geometry problem is that the lead-in ramps and the primary extraction are not synchronized, but are actually in conflict with one another. When we true an action, it consists of much more than just machining a few mating surfaces. First the lead-in angles (the ramps that lead into the lug seats) are re-cut to a true helical cam. The factory cuts are made with an end-mill, and are not helical.]
