Paul,
I found your photo very useful, Thank you.
I also found a chapter (chapter 7) from some report or text book on the web which defines the terms e and R for the Wankel Rotary Engine but it does not address the stationary and rotor gears and
their relationship.  Unfortunately I lost the link to it.
I also lost your email reply.  Would you please tell me again where it was I believe you said plastic gears are available.?
BTW, the actual gear ratio between the rotor gear and the stationary gear is 1.5 to 1 when comparing the number of gear teeth like us laymen do it. Of course because of the fact that the rotor gear
is rotating around a stationary gear the effective gear ration is doubled.!  Took me a while to figure that one out.

Thank you again for your help.
When I finish my drawings I will send you a copy of the AutoCad file if you would like.
Let me know.
Thank you,
Tom Henry

Stock Drive Products, W.M. Berg or Boston Gear. Use google.

Mazda has a very nice working model with metal gears and rotors but they 
are hard to find and expensive ($100). Here are a couple of pictures of mine.
If you do a really nice one you can get a lot of money for them.
