“You’ll now attach the first in a series of ladders and waterway sections.”
Materials: The pipe of the Waterway is metal, but the end fittings of the Waterway and the Ladder are plastic.
Aerial Base Section Ladder and Waterway
When working with the Section Ladders in these final stages of our build, note that they have specific ends. The screw holes are farther from the UPPER end of each Ladder, and closer to the LOWER end, as seen here:
Retrieve your Ladder 9 from the previous stage. Slide the LOWER end of the Base Section Ladder in between the arms of the bottom Ladder Guide A at the Bed Section of the aerial, aligning the screw holes as shown:
Secure this LOWER end of the Base Section Ladder into place with two (2) Type B screws, one on each side:
Slide the UPPER end of the Base Section Ladder in between the arms of Ladder Guide B at the top end of the Bed Section, and secure it into place with two (2) more Type B screws, one on each side:
At the base of the aerial boom on the right side, rotate the waterway Pipe B and Pipe C assembly (installed back in Stage 62) until the pin on Pipe B can be inserted into hole of the waterway cradle of Ladder Guide A, as shown.
I already did this back in Stage 69 to keep from losing these pipes:
Slide the narrow end of the Base Section Waterway into the open end of Pipe B (circled below), as shown:
Rotate the Base Section Waterway until the pin of the upper fitting can be pressed into this hole of the Ladder Bracket at the top end of the Bed Section, as shown.
We will need to undo this step in the next stage, so you may want to leave this pin unattached for now:
The first of our FDNY Tower Ladder 9 aerial boom ladders has been installed along with the related Waterway. On the real fire truck, this telescoping water pipe is designed to carry water up to the nozzle mounted on the Ladder Platform.
