DM you corrected me this past Sunday for calling the "ROCKER PIN" a pivot pin and now you are calling it the same. LOL!! If you punch a threaded pin out you take the threads and material with it and nothing left to rethread with the same size. OMG!!
The pin in the blade pivot and the pin in the rocker pivot are both unthreaded. So they are not too hard to knock out. After you knock a pin out, it is not usually reusable. So you either have to put in a new pin or replace it with a #5 screw (1/8" diameter) or an internally threaded barrel (1/8" diameter).
