After the Match Drilling of the #40 through the Aft Window and into the roll bar I riveted the fwd turtle deck skins to the fuselage and tailcone. I then removed the clecoes holding the aft window, and then lifted the aft window to a table and opened up the holes with a #27 drill bit suitiable for plastics. The next task was to final-drill #36 all of the previously #40 drilled roll bar. The Roll bar holes will need tapping to hold the round headed screws.
