Beginning to assemble the left main spar. Started by labeling each rib location with part number of the rib to be located there. Then laid out the ribs and labeled thieir position(1-14) and which parts needed to be added (like flap hinge bracket etc). The aileron bellcrank brackets get bolted to the main spars. I added the brackets for both right and left and also numbered the ribs and placement locations on both sides.
