Set #8
Alternatively the “cast” parts can be made from the solid, or from built-up, brazed assemblies.
Complete construction and machining details are included to make this possible.
For example this allows the builder to use steel for the truck frames, as was done on the prototype.
The wheels can be machined from steel bar stock. This seems like
a lot of work, but it is wise to fit the wheels with steel tires,
so the amount of machining is still considerable with a cast iron core.
Also the cost of wheel castings is considerable and counts a long ways
towards justifying the labor to make these parts from bar stock.
The engine cylinders can be made from three sections brazed together
and machined, and will perfectly match the jacketed look of the
prototype parts. Corrosion resistant materials such as bronze or
brass could be used here, although the cost of these
materials will be high.
Parts like the steam pipes and boiler
are designed to be made from standard heavy walled steel pipe and weld
fittings. This results in strong and flawless parts.
So by
using these techniques the builder can save the cost of the cast parts,
obtain superior strength for many parts which were of steel or cast
steel on the prototype, and avoid the potentially disappointing
experiences with internal casting flaws.
The possibility of discovering flaws inside a cast piece is completely eliminated.
