Brief Description: Seat backs--marking and match-drilling the forward
Started work on the seat backs...this took a whole lot of measuring, fabrication, and "measure thrice, mark twice, cut/drill once." First we cut 4 identical pieces of angle aluminum. Then using one as the master, we measured out and drilled the rived holes for mounting it onto the seat back panel. With it done, we used it as the template to match-drill the other three rails.
We did the same for the top and bottom rails, also made from aluminum angle but they mount onto the back of the seat.
