Top Longerons

0/4/12 Floxed Sitka Spruce longeron to the RHS. Both sides were trimmed back to the foam edges. Peel ply is then removed and the contact surfaces lightly sanded. The longeron is a datum point so especially needs to be straight. A very light coast of pure epoxy followed by wet flox to both mating sides. Multiple clamps are used and a big cleanup of all excess flox.

11/4/12 Did the LHS top longeron. Same process. The two stiffeners called out for p5-2 are omitted in my build as I will not be cutting out the sides for baggage so these are unnecessary.

Small Longerons 9″ long need to be 2″ high. 1″ pieces are laminated together for this.
