I started by clecoing the the doubler plate and rear spar together. Then I clecoed the hinge brackets on. I fluted and straightened all of the ribs. I then clecoed the ribs onto the spar. I drilled to #30 all holes in the spar except the bottom hinge bracket. I aslo drilled all rib holes. I clecoed the skin on and drilled all the hole to #40. I disassembled and started cleaning and deburring parts for primer.
