The swags were a lot easier on the upper wings than the lower, as the angles are greater, allowing the tool to fit without a lot of drama.
Bit of spare sheet to protect the spar and a go/no-go gauge used on every swag.
Tada! Right upper wing spar assembly done.
A few notes:
I put "top" and "right" on the wing, as it lets me know orientation for when I pull down the flying/landing wire attachment tangs.
The stupid bracing wire tangs at the compression struts are a super PITA. They're stainless steel and don't have the holes drilled into them - I burnt up a few bits making them, mostly because my drill press has only one speed and I couldn't keep the temps down. Step bits work best, if it is heartbreaking to turn them into useless smooth cones.
It would probably be cheaper to find some shop to drill them.
Two coffee cups because the wife actually brought me a hot cup of tea (it's in the forties today). She tries to play cool about the build, but I think she's actually kind of jazzed that there's an airplane being made by her husband in the back yard.
