Started measuring and trimming the J-channel material that’s used for auxiliary longerons in the fuselage tailcone. There are three sets of two J-channels that must be made from stock. I measured them using the same method I used on the longerons, and double-checked the measurements before cutting. Came out great! The ends need to be shaped to accomodate the bulkheads, but that will come later. Sorry, no pictures…
