Note - this step, the last task of chapter 14, happens _after_ completing the wings and chapter 19. PK

The spar installation took a long time mainly due to setup. The actual taping was relatively straightforward. John and I set up the fuselage on some sawhorses, then carefully shimmed it using foam scraps to get it precisely level in all directions. I then spent some time sanding the spar cutout to make a hole exactly the right shape and size. We then installed the spar and shimmed that until it was well leveled. All of this took nearly two days, actually, because sorting out all the slight variations was a bit of touchy work.
