Today, I installed the lower rudder tip. There are a few cuts to make and it took quite longer than expected to have an acceptable fit. I the drilled and coutersunk the holes. I'll rivet the part later because while working on it, I managed to separate the two halves where the nav light gets installed. So I took out the bolts I had glued in and glued the part together. I'll put in some new bolts another time.
