Below are detailed pictures of Lee
Weldons scratch built turntable.
For a full description of how this was
built

1) Pit Floor. Constructed of sheet styrene
with headphone jack mounted in centre. Circular track is cut from the
solid side of Atlas flex track, and soldered into a circle, using the
embroidery hoop as a guide
2) Side view of the bridge. I used
the operators house as a reminder of the polarity as it related to the
spur tracks and the DPDT switch. At one time the bridge had railing details
and an overhead power pole, but these were lost during years of storage.
3) Bridge Bottom: Shows the male
side of the headphone jack. The flat profile and the screw mounts
make this very easy to centre, which is vital to proper operation.
Also, note the assembly of tube and square stock that make up the bolsters
for the guide wheels.
4) Photo shows end detail of bridge,
with modified train wheels to guide the bridge along the circular rail.
Also shows the "Box" style construction of the bridge. All is
scratch built.
5) Headphone jack from below.
Shows the very simple wiring. Wire leads go to a DPDT switch to allow the polarity to be
reversed as the turntable revolves 360 degrees.
6) Shown with an F-7 diesel to show the size
of the table. You can apply the same principles using a larger embroidery
hoop to make a larger turntable.
7) Assembled. The bridge is
designed for 2 hoops depth. The bridge is rounded on the ends to
allow a snug fit.
