More work on the cabin frame. First some angles have to be cut and drilled. Some are looking akward because the frame is not sitting at a right angle on the upper fuselage longerons.



The two halves of the rear of the frame are the clamped on a board so that the assembly stays flat. One can make out the dimensions drawn on the board. The width is within 1/32 of Vans' dimensions on the plan.



The two halves are then joined with one of the plates fabricated previously.



Then two strips have to be drilled, they will allow later to then install the forward part of the frame. Here the inner strip is drilled.



Here the two strips are drilled, they are not drilled two full size, it will be done on the bench.



Here the two forward parts are positionned on the assembly. All the operations done today on the rear parts will have to be done on the forward parts.
