SEATBELT ATTACHMENT

Begin by cutting 2 four—inch lengths of the 5/8" triangular spruce piece. These two pieces go on either side of the bottom fuselage corners between the fuel tank and the seatback bulkhead. They must be rounded on both ends so that the glass lay- up will flow smoothly around the corners. Mount them in place with micro.

Next, you will layup seven plies of BID cloth over the spruce pieces. The cloth must lap up on the fuselage at least one inch everywhere.

While that layup is curing, make the aluminum angle pieces out of the extrusion stock. The hole for the AN4 bolt can be drilled before mounting. The AN525 screw holes must be drilled in place, from the inside of the fuselage out. The drawings show countersinking the AN525 screws on the outside of the fuselage. This is ok, but it does reduce the strength some.
