One thing I learned from the Right wind was that the blind riveting could be improved. In addition I have the pitot/AOA plumbing in the Left wing that makes it a little trickier.
I already have a wedge on the bucking bar for use on the rear spar, I just need a better spacer for the main spar area.
I gave the spacer a splash of varnish to stop it from deposit MDF dust everywhere in the wing.
