I start the former layout with the landing gear area. The front (F4) and rear (F5) formers each have a doubler (F4B, F5B). These will need to be aligned carefully so that the gear plate mates up correctly. With these glued together, check the fit of the gear plate. To get the bottom of the gear plate to sit nice and flush with the bottom of each former, I needed to added a 1/64" shim. I have since changed the laser drawing to account for this. With all three pieces ready, the formers (with doublers and shims already glued on) can be glued into the fusebox top. Once dry, use squares to hold the formers in position while gluing the gear plate in between (epoxy). The bottom of the gear plate needs to be flush with the bottom edge of the formers so that the fusebox bottom will mate to the gear plate without and gap...which would be a major reduction in strength.
