I returned to Ch 20 to attach the winglets after finishing and priming the fuselage with strakes and canopy. I waited as long as I could for this because storing the wings and winglets separately can be done very efficiently (see end of wings pages). Here we pick up on Step 3 of Ch 20.
Top Winglet Processes:
With the wing flipped upside down, I could do the layups prescribed in Steps 4 and 5. Before doing all these layups I also worked on carving the upper winglet to receive the internal bellhorn pieces I'd fabricated per the pdf file for this Rutan/Puffer sanctioned modification. The 8 and 9 ply layups take a while to do well and require some pre-fitting of foam wedges, so insure you are prepared before you get epoxy mixed up.
