Hi all, thanks for the feedback! Needless to say this won't be finished by the deadline. I've been working 6 day weeks for the last month or so and it doesn't look as though that will change any time soon.
Anyway, I got off early yesterday so....removed all the struts again! Somehow despite measuring and remeasuring, the wing was about 1/2 mm too high. The struts were all remeasured and a couple were corrected, and they have all been refitted. Hopefully today will see the top wing on at last...or at least, the left one...still have to do all this again for the other side!
