I thought I'd post a picture so you could better see the problem. A bit out of focus, but you can see by the ruler (divisions are in 1/8ths) that the rod sits about 1/8" off the wing. 1/16" balsa sheeting slides nicely under the torque rod.

Any new thoughts?

I did cut out a groove in the aileron so that the center of the torque rod is in line with the 'leading edge' of the aileron.
