Chicago & North Western #1385’s boiler continues to see steady progress. Since the last update, the boiler has been moved across the Continental Fabricators shop floor and is now on the positioner.  With the boiler now on the positioner, it can be rotated to allow workers to put it into the best position for welding and assembly in areas that would otherwise be difficult to access.

Installation of the crown stays is also in process. Crown stays are the staybolts that connect the wrapper sheets – which wrap around the firebox – to the crown sheet (i.e. the top of the firebox). The crown sheet is directly above the fire and is the hottest part of the firebox.

The crown stays (shown in green) support the crown sheet at the top of the firebox, preventing it from bowing inward from the immense pressures.
