I’ve been working on my wing tips for a little while now. At first I wanted to make a one piece wing tip out of aluminum and I started this by creating a cardboard template of the wing tip opening. I decided that a one piece tip would be rather difficult and I was especially worried about forming the flanges. After looking at some other plans that I have (Zodiac XL) I decided to form the flanges as separate angles. These will have nut plates installed so they can be screwed to the wing skins and then I will rivet a single flat sheet of aluminum to the angles to form the wing tip. So far I’ve made up three of the angles and pilot drilled two of them.
