top shaft pin

[Finnster]

The rollpin will break. Its really weak. I first did the allen key trick, but it eventually sheared. I then used a drill bit that was slightly larger, can't remem what size (was a fractional tho) and had the best luck with that. For the drill bit, I drilled the hole out w/ it, then pushed it thru. I bent/flattened the ends a bit to keep it in place. Since this solid, round, hardened tool steel, I think this is the strongest option.
