Short of a better word to call them, that’s what I’ve named this part. They get attached to the linkage that attaches to the solenoid armature and do the actual turning of the flipper. I milled them out tonight, then found the length of the linkage part I need, 0.660″ on 1/8″ centered holes. I also need a longer M6 bolt, 30-35mm instead of the 25 that I have.
Anyway, the small hole is for a 3/32″ coiled spring pin to hold things together.
