But I've just spend the last few minutes staring at http://www.keveney.com/Wankel.html There has to be some recipricating motion. If there wasn't, the apex seals would all trace a perfect circle.

Cut the flange off and old oil pan, clean it up, and made a new one (of the correct size), with JB Weld and 8oz fiberglass. I'll know tomorrow if I need to do some aluminum welding instead 8*) -- http://www.ronpaultimeline.com
