I have not posted in sometime but have reached a major milestone. It took me about two years to make the cylinder pattern, have the cylinders cast, and then machine the cylinder castings and all of the running gear. My goal was to have the chassis running on air by the end of the year. I barely made it. I now need to make the eccentric rods from measurements on the adjustable rods then on to the brakes and smokebox. The boiler is done except for the jacketing and the tender is essentially done with the exception of painting. I am hoping to have the loco under steam in three years.
