Donnie, I actually did this bit of destructive testing last night (before reading your post) and yes indeedy the "spar" breaks at the positon of the bolt. Thanks for the photo of your Jenny's center section. Unfortunately, the Nieuport doesn't have a fixed center section so the whole wings needs to be removable. ((Actually from what I can tell, the orignal wing may have been composed of two separate wing panels covered separately and joined in the middle))

Campy, I like your idea but since I'm using bar aluminum stock sheeted with hardwoods for the cabanes I'm not sure how I could connect the electrical socket at the top. Looks like I'll probably end up needing to fabricate some sort of bracket. Lucky I've got all stuff for silver soldering now! If only I had easy access to some brass square tubing!
