Today I riveted the Left tip rib on and then riveted the right middle ribs and tip rib in place. I then began work on the flap drive assembly. I was studying the plans and couldn't find a dimension for how far in the flap drive arm needs to be in the end. A call out to the email group gave me an answer of aligning the drive arm with the rear spar mounting hole. I then aligned the root drive arm with the outboard arms and drilled them in place.
Then I cut up some radiator hose and safety-wired it in place for a bumper pad.
