I put in a lot of time at the hangar but I think most of it was using the soldering iron to take the plastic off (yes, I know the plastic should come off to prevent corrosion, but my plane is going to be polished so I don't want the constant movement during the skinning process to ding things up any more than they need to be), and deburring holes, but at least I got started on skinning the left wing skeleton.
I continue to insist that Van's sends main spars with the holes too small to accomodate the lousy tolerances of the LP4-3 rivets. I know people disagree but there's no comparison between a prepunched hole on a rib and the ones in the main spar.
So I reamed out the flange holes on the main spar and then deburred all of them. Same with the rear spar.
I put a little primer on the inside of the skins along the rivet lines just because I was bored.
Then I clecoed everything in place and riveted on the doubler.
