Today I prepped three of the four bottom skins for the wings. This included using a Scotchbrite wheel in the air drill to create the taper at one corner each for the feather where the skins overlap, deburring all edges and holes as needed, final drilling access cover screw holes to size, dimpling all rivet and screw holes, then back riveting the platenuts to the access cover areas.
I also took the primed aileron pushrod tubes back and installed one in the left wing after fabricating the short bushing that is used in the installation.
