A perfect project for the monitor guys once they finish their builds 😉

Ummm... gulp... ummm... oh yeah! I am still working on the Corliss twin! Yeah, thats it!

Whew...


There are some here that could make one. Like the guy working on the merlin, just for one example. I might be able to make a nice display stand for this!

Here is a longitudinal cross section to add to the collection.
The individual components are not that complex in themselves. There are just a lot of them with twelve cylinders.

Hey Vixen,

The split case concerned me for a bit, but I think I could get it done.    The cam gear drives and induction would have me nervous though!    Not much room for a valve cage on those heads....might have to move them slightly...or run with the valve seat in the head.
Crankshaft is ROBUST....interestingly   The output shaft geared off the center of the crank is only 24mm of titanium!....

Hi Dave
The center drive is a neat way of overcoming the potential problems of long whippy cam shafts and crankshaft.
The show stopper is probably the twelve individual inlet stacks, trying to balance twelve individual carbs could be almost impossible as would a making a miniature 12 outlet mechanical fuel injection pump.
May have to settle for a Stuart Turner

Once the Wallaby is done.....I'll have some band width ....hopefully...

The center drive isn't the problem....Getting the stack height of all the cylinders and the gear mesh right..would be a challenge!!!! and  .as you say the induction would be tough to do.....One could go the Turbo version of this, and put the Propane feed in a fake turbo housing......

Need to talk to Keith about his fuel injection system.....

Building  a turbo Can Am version would be the smart way round the induction problem. No need for a working turbo on a scale model. Then a single fuel injector a la Keith, would be a good way to go.

When you finish the Wallaby, I can give you some plenty of well documented photos of a 917 strip and rebuild.
