I knew someone was going to notice that. That Nelson nut was too long to get the throws I wanted on the elevators (50+ degrees). So I just used the Dubro nut/cone and cut it down. I didn't want the Nelson horn to turn on the bolt so I used the Nelson nut as a lock nut to make sure the horn stays put. Maybe not necessary but I cranked it on there pretty good and that horn will not turn for anything. It was just a last minute idea.
