I bought into the taper pin argument on matronics blog. After seeing pictures of RV's nosing over I didn't want to experience that if I could prevent it. Obviously a good landing technique would go a long way to preventing nose gear damage:) The rub came in while trying to ream the hardened nose gear. It was not going to happen by hand so I called Sam for help. We used his milling machine and most of his afternoon getting the pin in. Thanks Sam.
