That fitting can be handy in a lot of instances. I was building one once and my boss walked by and said "hey you buildin a piano" of course I replied " nope just an airplane". I guess I was taking a little to long. I like to brake a kink kitty corner on the angled side. It seems to fit into the pitts a little better.

Set dividers to RA - 4A. With 4A as center, strike an arc counter clockwise.
With 1A as center, strike an arc.
Where these arcs intersect is the center point for radius 1A - 4A.
I have made this fitting many times, and this method never fails.
Assembly is tricky; an inward kink on the developed cheek is helpful.
