Dynafocal Engine Mount for Pitts

[chrislange]

Hi Everybody

I just started to draw the Dynafocal Engine Mount that is shown in the pitts S1S plans. Is there any description available for the dynafocal engine mounts ? If I understand it correctly all mounting points are align to one same point. I laid the radius tubes between the mounting points on one level with the focus of the mounting point and the point where all mounts are facing to.
So who knows how to draw and build it correctly ?
