Well I managed to get back around to building the the liberator. I framed both wing halfs and then joined them . That is where the problem came in. I thought I wold measure the wing panels. Ithen found out one is 5/8 on an inch shorter than the other. I looks as if when the plan was reversed at the printer it shrunk. Not a good time to find out. I added a 1/4 inch spacer between the root ribs and a 1/4 inch at the wing tip. I the spaced the nacelles in the proper location. I am jigging the wing to add the nacelles and should have more pics later tonight or this weekend.
