DIY Roots blower: rotor profile drawing/dimensions

I set up this CAD drawing for spacing the rotors 2 inches apart. But when i actually make it out of wood, I think I will resize the dimensions so I can reuse my hole saws from before. Trying to find .518in radius I.D./O.D. hole saws would be too difficult... With this base drawing I should be able to scale it up to any size i want.

Roots Supercharger Rotor Profile

I wanted something simple so I wanted to see if I could make the classic roots rotor profile in cad. Doing so I discovered why my wooden rotors didn't mesh properly. I totally cut the rotors wrong, but the proper profile also seems rather simple to make.


Now this looks much better, I'll post the actual dimensions and drawing later...

Even though I designed this in a CAD program it still seems like it would be possible for the layman to make a real supercharger.
