This morning I was able to complete riveting the top of the wing. Although I'm disappointed in its finish, I'm pleased to have achieved what I had set out at the beginning of my 4 week vacation, that is to have the right & left wings to the same stage of completion. They require fitting of the wing tips only prior to preparation of painting. (matt black is gaining in need!) I'd like to thank GAM, PGC & in particular my wife KLH for their invaluable help & support over the last 4 weeks. Thank you all.
