Wings!! Bloody annoying trying to get them on and off by yourself, without dropping, scratching, bumping or otherwise damaging the buggers.
No wonder all the advice I read says to get 2 people on it. Trouble is I'm generally working on the plane by myself (except for @nomadpete's invaluable assistance with electrical stuff), so I really needed a way to support the wing and be able to shift it up to the fuselage by myself.
Some measuring and half an afternoon's building later, the wing tower is born. Braced in all 3 planes and designed to sit on the wheeled dolly that holds the wings when they're off. It's the right size on the top to support the wing cradle, which can be slid back or forward to get some fine adjustment in the vertical height (it's angled to give incidence).
I only had time to drop it up to the shed and put the wing on it, didn't have time to attempt a fitting, but it moves ok and seems to put the mounting points at the right height and incidence.
