Up the Creek Column - 3
Installation
Per Tomar's instructions I
started installation by drill-
ing a 1/4" hole between the
Oakhill main and siding, being
careful to deburr the edges of
the hole. The semaphore post
and control wires pass through
this hole so any splinters can
become a problem for smooth
semaphore operation (4).
There was a splice plate under
the Oakhill roadbed below the
semaphore location. Luckily I
could mount the servos com-
pletely on the splice plate so it
wasn't a huge problem.
I checked the semaphore
against the hole to ensure it
fit and the control wires didn't
bind before proceeding (5).

wires and the tiny power
leads for the LED at the
top of the mast.
