Need a tutorial for modeling airplane propellers

I need to model an airplane propeller to be made on my cnc machine for my father-in-law. I have the cross section data in iges format. I remember long ago seeing a very good tutorial that explained how to use the cross sectional data to achieve a functional propeller. Unfortunately, it’s been too long, I can’t remember how to do it and can’t find a tutorial of this type anywhere. Can anyone point in the right direction?
