I started morning after a good sleep in and then spent the next 30 minutes hunting for the angles for the wing tips, finally found them packed in with the rear spar. Once I got the hang of the Zenith crimping tool things progressed fairly well, but very slowly. I finished crimping / bending the top and bottom angles and then placed the wing tip skin in place to trace the required cut out. Probably spent more time then requied getting a good fit, but hey I'm happy.
