We started today by finishing the rudder. The mantra of "cleco, drill, disassemble, debur, dimple" is becoming very familiar already.
I didn't get a picture of it, but we also fabricated two strips to match drill to the lower rib and skin. These attachment strips are put in place for the fiberglass tips (installed later on).
The weather looks like it might be favorable for priming tomorrow, so we made a quick run to Home Depot to pick up acetone. Fingers crossed that we'll be able to start and finish priming tomorrow. That's the next big step before being able to start riveting.
