When I entered this chapter, I was fortunate enough to have some extra cash, and Dennis Oelmann happened to have a completed spar for sale. The center section spar is a critical structural member, and the idea of having this chapter just be "done" was appealing, especially after dealing with the spar cap tape in Chapter 19. (I had started that chapter before this one.) I'm glad I did. Dennis match-drilled the spar to my wings, which is a tricky bit of work out of the way. And the spar is absolutely beautiful work - Dennis always does a fantastic job.
