Brief Description: Set rear frame channel and upper seat support
Today the jigs I spent so long to create came into their own. After drilling and temporarily fastening the attach plates to the rear frame channel, I inserted the wing jigs and used that to set the location of the channel. Actually, the very first step was to trace and cut out a notch in the rear side skins to accomodate the attach plates as they protrude through the side of the fuselage. Once I drilled and clecoed the rear frame channel to the fuselage floor, I was ready to move to the placement of the upper seat support. Tonight I got as far as setting the station and width for this part, trimming the ends to fit within the longerons and putting everything in basic position for marking and drilling tomorrow.
