Fabricated the doubler plate and washer plate for the pitot mast. Made a bend at the aft edge for rigidity along the spanwise direction, and added a row of rivet holes to the outboard edge. Also added rivet holes to ring the pitot mast. Marked, drilled, nibbled, and filed streamlined shaped hole in outboard wing skin. Match drilled the skin to the doubler plate. Time to prime all this stuff.
