Measured, marked and cut the notches to make a left and right 404 rib. Deburred and cleaned all edges. Moved on to all the edges of the 404, 405, 706, 707 and 708 ribs. Work went pretty fast with two of us. Started making a "left" and "right" pile to prep for next step in assembling the skeleton. Learned a new process in fluting the flanges to straighten the ribs.
