Thanks for the replies on the wingtips guys. I will bring you up to date when I am in the process. Like I said, I wil be adding strengthening sheets to the internal side of the TE sheeting. Once completed, I will pick up the wing tip installation again. The way things are going, I will probably be ready tomorrow night, or Saturday. Gotta take out the wife once in a while, and Friday fits the bill. No football either this weekend, so another couple of long building sessions are planned. Will need to go by Lowes and get more kerosene for the space heater. Will post more later.
