Well makin th pinion blank is the easy part and heat treating it is easy as well the real issue becomes in actually cutting the teeth and I say that because I don't have the set up for cutting te teeth so I'd have to send that somewhere to be done but im definitely kicking the idea around of giving it a whirl...anything can be made to work its just a matter of does the person doing it see potential gain and I see it as an opportunity to test out some things so maybe I will try it
