I must have forgotten to tell you to take the twist out while fitting the
containment bulkhead parts? Sorreee
In fact the rear bulkhead and the torque tube when bonded in all have an
effect on locking in the distortion, flexing the tub in torsion before
these are in will demonstrate that the two sides move fore and aft as it
twists. Early efforts to stabilize the tub, in Chuck Pops' cradle for
instance, will pay off handsomely. So, I would say, do this first, then
tempo fit the top on, with the sternpost and check for twist at this early
stage.
