I made a start on the tailcone bulkheads today. Try as I might I couldn't get to grips with Section A-A on DWG73 that shows the position of the WD-409 tailwheel weldment on the forward face of the F-812 bulkhead assembly.
With the help of the VanAirforce thread listed below, and some more head scratching I got it nailed. Firstly, my drawing has an 'incorrect' dimension on it that was later revised, and secondly, the drawing itself isn't very clear. Hopefully the pictures below will help someone else.
VanAirforce thread. If this link breaks, do a search on WD-409 and you'll find it. http://www.vansairforce.com/community/showthread.php?t=18155
