I've been putting the assembly of the seat backs on hold for a while. My plan is to order the Classic Aero aviator seats and they do not require the Van's seat back assembly. But seeing how the order lead time is considerable, when I do place the order...I won't have seat backs for quite some time.
I better put these together, if not for permanent means at least I can use them for temporary means.
I had all of the angles cut previously and all required notches and and radius's have been completed. All I needed to do was layout all of the dimensions and mark center lines.
The fan spacer comes in incredibly handy here, I couldn't imagine the time it would take to make each hole by hand.
The part that takes a bit of time is to mark the holes on the sides of the seat back assembly. I can't use the fan spacer as the holes are not equal distant, and they are totally dependent on the grooves of the seat back. I decided to make a drilling template out of scrap. I bent the scrap so that it would fit in between the groves in the metal and I carefully placed two holes according to the dimensions on the plans. Now I can use this drilling template to drill all of the holes.
