Clecoed spar channel, reinforcement plate and hinge brackets together and riveted. Drilled out and replaced one flush rivet. Experienced moderate pain in my left arm from simultaneous bucking and driving. Sanded, polished and fluted VS-404/405/407/806 ribs. One rib has uncut lightening hole; neither drawings nor instructions showed the hole should be cut, so left it alone. (I suspect this hole would be cut if strobe light were to be mounted on top of tail.) (See 28/29 March 2002 entry for more.) Drilled and clecoed 2 of 3 ribs to rear spar.
