Ok, I finally have installed my inertia reels in the BH. I had two plans, A and B. I ran both by my son who is an engineer for Boeing and by Bob Barrows. The verdict? Either would work. Plan B is the best option because the tubes are in tension. I went with plan A only because long ago I had welded in the T10 tube from the middle of the aft spar carry through forward to the X in the center of the cabin. That was a recommendation from Bob to install that tube if you mount your 4-point to the aft spar. When that was welded in that was the plan. Another reason is it is much easier to fabricate than plan B. If I had not welded in the center tube I would have done plan B.
