BUILDING A STUB SWITCH
AUGUST 28, 2010
[home]
The turntable in the shed was not working as planned.  It could only handle one car
or locomotive at a time and caused a number of minor derailments when it wasn't
aligned perfectly.  When the pivot screw broke, I decided it was time to replace it
with  a track made of regular rail.  But within a couple days, I figured why not two
tracks, and make a stub switch starting outside the shed, in order to maximize
space inside the shed.
VIEW FROM INSIDE - you can see the curved rails as they converge at the
door.
VIEW FROM OUTSIDE - The rails mounted on 2x4's move left and right,
bending at the foreground to line up with the diverging rails of the switch
NUMBER FOUR FROG - It's an aluminum casting I got from Peter
Nuskey, my rail supplier. In this case there was no need to bolt the rails to
the casting.
LEVER ASSEMBLY - Instead of a Harp Switch Stand, used on the
prototype for stub switches, I built this simple wood lever mounted on a piece
of aluminum angle.
LINED UP FOR THE LEFT TRACK - The 2x4's pivot on a 2x2 which is
bolted to the metal connecting bar. It fits nicely under the door without
interfering with it.
LINED UP FOR THE RIGHT TRACK - The 2x4's slide on the light colored
piece of wood.  The wood-on-wood friction is OK because it keeps the rails
lined up.
A TIGHT SQUEEZE - I had to modify the door, but now it closes just fine,
barely fitting over the rails and the lever.
