F22’s doubler (0.2 hrs)
Ok, I admit it! This was totally lazy and unnecessary, but I had the time and the tools, and I like to avoid sanding wherever I can.
The problem is that the doubler that goes on the aft face of F22, needs to be cut (or sanded) at an undetermined shallow angle.
Using a caliper, I measured the thickness of the foam (6.87mm), and the length of the base of the ramp (26.39mm). With that, all I had to do is the inverse tangent of 6.87/26.39, and got the angle 14.6˚.

Then I set the angle on my table saw...
... and committed to the cut.
The result turned out very well, and required no sanding at all.
You’ve got to love math!
