Tedious. Not much to describe. Jsut 100's of rivets.
Riveted the main spar, then the nose rib skins, then the aft rib skins & trailing edge skins.
Did not rivet the fuel tank bay upper skin - still have to assemble the tank, insulate, etc.
Did not rivet the root skins - either the nose or aft, since I still have to fit some angle pieces for the slope / compound curve.
One issue is that the riveter jammed. Could not pull off the rivet; put some extrusion between the rivet head and the riveter, but they slipped and really messed up one hole on a nose rib. Talked to Zenith and they suggested cleaning up the hole, stop-drilling 2 cracks, and then putting a patch over it. Had to use an A6 rivet (center of the patch) to fill the hole that was now oversized. I'll just say it's a special location for an aux static port!
