Not sure if this helps, but here's a thread I did on a 2 piece wing. The wing I built is abit smaller, but should give you some ideas of a home brew setup.

This plane is still going strong with about 200 flights on it.

i also have a 96" old timer with a 2 piece wing using this method.
Used the same method on a 1.5 meter glider, 2 meter glider ( 3 piece wing) and 2 park fliers, but only used one smaller rod instead of 3 5/32" rods.

Outer tips do not have to be an issue re the ailerons. Are the ailerons full span or barn doors? IF barn doors, then just put a servo in each out pannel. If full span, you can join the break using the same method as the wing rods, but use much smaller rods.
