3. Place both halves together and apply pressure evenly the length of the span bolster for about
10 seconds. Use a toothpick to smooth out any excess glue along the seam. Set aside to cure
for an hour.
4. Repeat steps 2 and 3 for the second span bolster.
5. After the Span Bolsters have cured, use a small file to smooth out the seams and any excess
glue. The sockets can be cleaned out with a 7/64 drill bit if necessary.
6. This is a good time to pre-thread the mounting holes for the coupler and end trucks. Pull one
each of the black ¼" #4 and #2 screws from bag F. The locations of the screws are shown
below.
7. Start the threading process by turning the screw until it starts to bite into the plastic. At this
point, turn the screw about a 1/8 of a turn then back out about 1/16 of a turn. Rotate the
screw back and forth, advancing the screw about a 1/8 turn each time. Keep advancing
until you feel notable resistance in the case of the truck mounts, and until the coupler screw
reaches the top of the Span Bolster. Note the depth of the fully seated screws below. The rear
truck mounting screw does NOT go in as far as the front screw.
