need help with building a Coles' 1" scale Case Traction Engine

[jeff l]

Hello , My friend had purchased what appears to be the last set of castings and drawings for the Coles' 1" scale Case Traction engine and is having a difficult time finding the spec's for the gears which he needs to either purchase or cut .
 If any one has built this engine could you please provide me with the necessary spec's for the gears needed for the build , my friend doesn't have access to the internet so he's asking me to post this for him , thank you .Jeff

Hi Jeff,
I have a 1 inch Coles Case traction engine that I built back in the 70's. Later today l will pull it out to take some measurements. I'm curious, the drawing set has a sheet showing all the gear train. He would need a set of drawings to build the engine so he should have that sheet.

Thanks George , I'm not sure that he has all the prints , I do know that he's missing some castings but that's another problem ,Jeff
