Yes, I was going to screw or rivet that connection, but I'm convinced that the epoxy will do just fine, so I left it that way. > I plan to use the 18%/15% wing section in precisely the manner you would > have preferred (bent spars) except that I intend to move the WAF's > outboard to the flap /ail intersection.

I'm too lazy to drag out all my old books and try to remember the fairly simple method for determining the spar cap dimensions, but I would think you couldn't go wrong by using the same 2" thickness that the plans call for, tapering smoothly (starting just outside the fuselage) to something like 3/8" at the tips. Of course if you move the WAFs out, you have to make sure you have enough material for them, which might explain why the plans show the spar caps on the center spar are the same height all the way to the WAFs. You might even need a different kind of WAF, but the good news would be that the further out they are, the less load they have to carry. ANC-18 (Design of Wood Aircraft Structures) would probably help, and I'm sure there are other good sources of WAF design data.
