My friends Steve and Tom came over today and we knocked out the left wing skin riveting. Everything went just about perfect. The four holes in the angle piece that ties the Gretz pitot tube mount to the adjacent rib had to be opened up a bit so the rivets would fit, but other than that, the day was totally uneventful. I'll wait to install the pitot mast and pitot tube until after I install the new phenolic connector for the pitot heater.
