Didn't some old fighterplanes fire through the prop and spinner? How did
that work?

Thanks, Dick

The prop was on a hollow shaft driven by a spur gear, so that the
input gearing was out of the way. The gun fired through the hollow
shaft. Some German airplanes had this, I think, and the P-63 Airacobra
did too.
