Stephensons Rocket
 

Hi,
I am building a model of the Rocket. I cannot figure out how the driving wheel con rod eccentrics are set up. Are they at 180 degrees to each other, or another angle or are they both the same on each side? Thanks for the help.

Do you mean the cranks or the eccentrics which are hidden under the boiler to operate the valve gear. If the cranks then like all two cylinder locomotives they are at 90 degrees to each other. The pairs of eccentrics will also be at 90 degrees to each other or else the locomotive wouldn't run.

thats just what i was looking for thank you very much
