Ken, I think he is saying that the spar sticks up above the ribs instead of being flush. IOW, the covering will not contact the ribs near the spar and any sheeting may also not fit correctly.

argileh - did you clamp everything in place or just rely on the CA. Are you just using CA? Do you think you could relocate the spar if you used CA debonder to loosen the current joints? Maybe apply a little clamp pressure while applying the debonder until the spar shifts? Then reglue as needed. Let set before removing clamps.

I still like my Tite Bond II for this stuff but not on top of C
