See below from Rob Schmitt. I'm fooling around with list settings. If this makes it, I'll be on to something...

If I recall correctly I just added an additional piece of 3/32nd plywood on the center main spar forward side to get the additional space needed so the outers wing WAFS would slide into the centers. I did not have to do that at the rear spar. Rob Schmitt In a message dated 11/12/2013 7:11:21 A.M.

Doesn't the outer spar need to be narrower for the waf to go inside the center spar waf? I know it does I'm just missing something. rk from Sprint! << They must not nest then. It's been a long time since I built mine, and that area is one of many in the plans that require careful study, and sometimes, wild extrapolation. Come to think of it, one of the things I'll do differently next time is butt the main spars up against each other to eliminate the gap between the spars, and the only way that could happen is if they are both the same width. A bushing is then used through the 3/8" bolt locations (and epoxied into the wood), so you only have one 3/8" joint per pair of WAFS, rather than two, and it's quicker to disassemble, and less of a hole is needed on top of the wing. I didn't invent this...I read it in one of the old newsletters.
