I up drilled all of the holes on the bottom of the wing for the wing tip angles to #30. I also removed the protective plastic coating. Next I up drilled the holes in the top of the wing for the wing tip angles to #30 and removed the protective plastic coating. I then started to dimple the holes for the countersunk screws. I completed the all of the wing skins and the two bottom angles. The top angles will need to be done with a special C-clamp I made up when making the wing tip for the other wing.
