What did I do wrong building the two piece wing for my Chrysalis?

I just finished building Chrysalis two piece wings. I found I had to cut into rib B so the spar would lay flat on the shear web, and then had to shim between the two shear webs to build up to profile. After all was said and done, I ended up sheeting over the top spar, as opposed to butting the 1/32 against it. Where did I go wrong?

My guess is you probably used the original A-B shearwebs that come in the standard kit instead of the special ones that come with the 2-piece option parts. The special ones are thicker, and have more taper along their length. The A and B ribs for the 2-piece wing had to be thickened to provide enough material at the edge of the joiner rod hole, which then required the thicker shear webs.

You will have a little trouble covering the area between rib B and rib C, but structurally you will probably be OK. You might want to add a tapered piece of spar stock on top of the spar between rib B and C to get the spar level with the center section sheeting at rib B, just to eliminate the covering problem in that area.
