Many steps are covered by this entry. The wing spar per the plans took a fair amout of work. Many holes needed to be countersunk. The spar extensions needed to be fit and rivetd into plas. The wing ribs all needed to be debured, straightened, and dimpled before fitting in place. The left/right labeling of the ribs was very confusing. It took more than one try to get the correct ribs in the correct positions.
The aileron and flap mounts all eeded to be duburred and final shaped as well.
