I am studying up to get ready to assemble the wing center section on the -3B with Louise, and wanted anyone who's done this recently to check my thinking. The instructions show what is essentially a full-bulkhead jig in drawing SK-17, but the instructions (dated ca. 2000) talk about just building what amounts to false spars to use as spacers for assembling the front and rear parts of the bulkhead. I don't see much advantage to the SK-17 fixture, and am assuming that the "false spar" method is a later way of doing it...and sufficient?
Thoughts?
