These engine projects are getting a little jumbled; a Holliday, Ripley and Marsh that need new boilers and a Kimball that hasn't really been started. There are currently 4 threads that were intended to chronicle these individual projects, but I can see a lot of benefit in doing the actual construction of each concurrently. Here is how I will proceed.
This is a foam core tray that I put together to keep all of the little parts, purchased or scratch built, together with the appropriate project. I am hoping that this will help me to see when a particular phase can be started and benefit all 4 projects.
Here are Preston's drawings of the 4 engines enlarged to 1/18 scale. I used the driver diameter as the "yardstick" 36" for Holliday and Ripley, 30" for Gurley and Kimball and 28" for Marsh. To back check the enlargement, each boiler should be 32", (which they are)
A real striking difference when viewing all together is the difference in cab sizes. The Ripley appears to be the smallest and the Marsh the largest. Can anyone attest to the roominess of each cab?
