Does anyone have any drawings of a 12A.?

[Dualist]

Before anyone says it, I did search before I posted and I do have the Yamamoto pdf\'s for all the calcs and stuff. But over the years has anyone done the 12a in either AutoCad or Solidworks.?

I\'m asking as it\'ll save me a load of time, would prefer them in 2d but I can work in 3d just as well.

I\'m planning on designing and building a single rotor engine for motorbike racing, I have a couple of 750 bottom ends as donors so I can start to draw that lot up and start on machining the gearbox plates.

I only need the rotor, the rotor housing and e-shaft, the e-shaft will be for reference as I\'ll be machining my own up as I will with the end plates.

Many thanks in advance for any help.

Dave.
