The crash walls were made from
MDF. 1/4" for the small radius
curves and 1/2" for the large
radius curves and straights.
Because of the elevation changes,
the crash walls would require
a slight curve on the upper and
lower edges to follow the contour
of the track surface.
The routed sections were reassembled.
A strip of MDF was cut to a width
which provided for the lowest
and highest point of the crash
wall and a length about 6"
longer than the track section.
The MDF was then clamped to the
section, aligning the bottom edge
of one end of the crash wall with
the lowest point of the track
surface. The crash wall was then
bent around the curve and clamped
into place. A pencil line was
scribed to mark the top of the
crash wall which represented the
height of the crash wall above
the track surface - this was done
by running a spacer block &
pencil along the track surface.
The crash wall was removed and
a jig saw was used to cut the
top edge of the crash wall, following
the scribed line. A parallel line
was then drawn on the bottom of
the crash wall using a carpenter's
square set to the depth of the
crash wall height. The bottom
of the crash wall was cut using
a jig saw. The completed crash
wall was then glued and screwed
to the track section.

- The outer crash wall are
2" above the track surface.
- The inner crash wall are
1" above the track surface.
- The crash walls extend 1"
below the cross members.
- For the smaller radius inner
crash walls, vertical slots
were cut to allow the MDF
to conform to the tight radius.
The slots were then filled
with "Fix All" and
sanded.
