Worked on the elevator pushrods (3). The instructions are very straight forward and there are no real gotchas. Use the template for marking the locations for center punching and then drill / match drill and cleco. The insides need to be primed before final assembly. I trick I learned online is to cut off the fingers of a latex glove and use that to cover one end and pour the rimer inside. Cover the other end and swish the primer around really well and dump the excess back into the cup for use on the next tube. All 3 tubes together used about 2oz of Akzo primer. Once I rivet the ends on tomorrow they will be ready to scuff and prime the outsides of the tubes.
