Then I added the pulleys. The instructions only mention drilling a hole for it in the main spar prior to adding the leading edge boards. But it’s so tight, I decided to paint and install it now while I can!

It’s hard to see the profile, but if you hold it at the right angle, you will see it matches the rib profile and tapers towards the leading edge.
Whew! That was a lot of work. Now to do the wing tips and trailing edge.
