We engineered a very solid installation for dual BAS inertia reel shoulder harnesses. That included moving the seat belt inside anchor points for pilot and copilot aft to a functionally better location. The cross tube which supports the inertia reels is a 1 1/4" CrMo tube with custom brackets welded by Charlie Collier, Master Welder. He brought his oxy-acetylene welding equipment to us so he could get the position of the backets exactly correct. These photos span about 2 years for this complicated installation. We were lucky to have counsel and other machining help from Ron VanSickle, Master Machinist with is Bridgeport.
