Deburred, prepped and primed the RH elevator understructure. No pictures of that but someone asked me to explain what a cleco is. A cleco is a temporary fastener that allows you to hold 2 or more parts together. There is a spring inside of a cleco. You take a pair of special pliers and depress the end of the cleco and 2 barbed prongs extend from the opposite end. You insert those 2 prongs through the drilled hole in 2 or more parts and release the pliers. This causes the prongs to retract and, as they get near the base of the cleco, a piece of metat between them spreads the prongs and the barbs catch the sides of the hole and pull the parts together. Pictures below.
