What size lathe would a person need to craft one of these.

Prop? Or Steve Rosines PSRU?

Sorry Paul, while the PSRU is cool, I am talking about the adjustable pitch
prop.  My understanding was that the majority could be made on a lathe, but
I am not sure how to size it.

I think your average 10 inch swing lathe ought to do it.

BTW there is a move afoot at the SZP skunk works (my hanger neighbors & LSE) to
build carbon fiber blades for a Hartzel hub. Should drastically reduce
the weight of a constant speed Hartzel for experimental use
only of course. The hub itself does not weigh much. It is those solid aluminum
clubs attached to it that are the majority of the weight.
