Wing Rib Drawing

The wing rib drawings are full-size, but they come on two sheets, which you have to join together. The way I did it was to use a straight edge to line up the chord lines as best I could (they weren't perfectly straight), then make sure that there was exactly 31 inches between the wing spar centerlines. This worked out OK, but there ended up being a gap of about 1 inch between the two sheets of paper, so I decided to trace the whole thing onto a single sheet. Then I made a copy of it, and that's what I'll be using to build my wing ribs.
