Then tighten as much as I could then used a brass bunch and hammer and shocked it. Used brass punch hooked into a groove on the jam nut and hammered it t

You can buy the special spanner wrench for YHM forearms and it will cost you about 40$, Or if you don't care about a little peened slot, do what I said.
