After the pins were punched out, I opened the holes out in three steps, working up to a 23/64 size bit or 0.3680. These are the bit sizes (pick one) that allows for a 7/16 x 14 tap.
I know, I was supposed to use tap oil. I didn't wear safety glasses either. Now that we're punched, drilled and tapped we need to use the bolts to make the pins.
