Unfortunately I cannot work on the Sea Vixen, full time, with business comittments.
But here is more:
The pushrod section going up the rudders is reinforced with tin stock at the bottom, and due to limited room, a 3/32" ID tube was split and soldered to the upper portion.
The drawings show no details of the rudder construction. Jack told me to "make it any way you want". He also pointed out that the the horizontal grain on the plans is wrong. The grain on the rudders should be vertical. This also makes it possible to bend the inboard side of the rudders to the airfoiled shape. (The outboard side is flat.)
The 1/8" flat rudder sides are carefully cut, with some positive incidence added to compensate for the high stab and get equal turns inside and outside.. (alfadog, Bob Whitely, has written much on this subject in this and the other forum),
Since the full size Sea Vixen rudders blend into the booms at full width, I added a leading edge piece that will be between the rudder sides. The extremely limited room for the horns will be addressed the same way that the full sized Vixed addressed the problem. It has a box shaped area under the stab that also has position lights.
The outside of the rudders are rough sanded to shape in the photos, and will blend into the booms nicely.
In order to locate the stab with the swept wing, I made simple fixtures, for locating the stab,that are positioned at the inside of each boom.
