Here is a 6 station prop, drawing AD644, for a Sopwith camel:

Page 12 could be traced in MoI, with the cross sections rotated and lofted. Still need to do the Hub.

A nice link, which explains cross sections very simply, is : http://www.nmine.com/propeller.htm

(I imported the SLDPRT to Geomagic design, saved as step, and imported to MoI.)
