    Bruce, The radius is there to avoid stress cracks that form at sharp points. The radius doesn't need to be much: a 1/16" radius should be plenty. The aft end of the longeron has that notch in it just so it can fit around the bulkhead. Don't shorten your longeron, just extend your notch a little bit. Just enough to add a radius in the corner.
