Before starting to work on the wing today I installed some 1x1x1/8 aluminum angle on the vise jaws. This is intended to keep the jaws from deforming any parts I may need to clamp in the vise.
Today I riveted top skin from the leading edge to the main spar.
I also fitted the wing walk doubler to the wing. I sued the shop break to break the front edge of the double so it will lay flat against the wing skin below the leading edge.
