Made the doubler plate for the starter solenoids, drill all appropriate holes in the firewall, dimpled and countersunk, riveted on platenuts for the battery as this would be harder to do with the engine fitted. Had a fellow builder and friend Wally Ogilvie come and give me a hand to hang the engine, all bolted on, then Wally set my prop govener with cable support, safety wired and bolted in place. Connected the cable and one job down, plenty to go.
