The Cab, Firebox and Boiler
- February 15th, 2023
The boys in the shop were scratching their head on where to start on the
pilot. It has to have a working coupler on it and the pivot has to move
so that it can be hidden, as the original does. I told the boys to go
look at the Big Boy to see what has been done before. After a few
measurements and false starts, the boys made what you see here. What is
usually easy to mount to the frame, this one is not. It had to be
mounted to the bottom of the smokebox, because the chassis has to flex
to go around a five foot radius curve. The chassis is mounted to the
boiler in only two places, between the cylinders and under the firebox.
The chassis is hinged between driver 2 and 3, and to support the weight
of the boiler, there is a hidden roller mounted to the bottom of the
boiler that rides on the top of the chassis near the hinge. With the
pilot mounted at the correct height it is time to move on to the details
that make an engine what it should be.
Piping and details seem to take the boys many hours to add to the
engine, but the end result really makes things look good. Pumps,
ladders, pipe and fittings, handrails, electrical connections, and other
details all have to be sourced or fabricated and installed. This is the
first engine that BLW has built with smoke lifters, or elephant ears on
it, and will most likely be the only one, as I think it hides a lot of
details that should be seen.
