Cylinder - Steam port 2.JPG
7-Jun-2005
The casting for the Cyclinder was not made with any
cores, so the steam passages must be machined. Prior to the machining
here, a hole was drilled down through the valve chest into the
cyclinder. This provides the steam passage from the valve chect to the
cyclinder. The hole on the top portion of the valve chest will be
plugged later and covered with the by the cyclinder wrapper.
