Product Description


A simple deck turntable for your On30/On3 0-4-0 critters!!

Deck diameter is 3.5" (90mm), turntable rail length is 3.25" with On30

The turntable comes complete with a motor+gearbox and additional nylon reduction gearing for smooth, slow and realistic operation. The high-torque motor only requires 1.5V so can be run from a single AA battery, but better solution is from a variable low voltage DC supply, a DCC loco decoder can be used (adjusting speed CVs to limit voltage).  The motor is very quiet!

Operationally the turntable has sprung plunger contacts for reliable power-routing of the rails - a robust type used by the electronics industry.

The turntable features continuous power-routing designed for DCC use. (not a split ring design). Polarity is changed with a DPDT switch (not included) for DC, or for DCC a reversing module is best to ensure automatic continuous operation of a sound chip. Wiring instructions and schematics are included in the instructions.

Code 83 or Code 100 options are available.  if you are using Peco's On30 track then you will find installation easier if you order code 100 to match, otherwise we recommend code 83 for a finer look that will work with all modern rolling stock.

Rail is pre-soldered assembly, and aligned into place as part of the design

The deck surface is laser-cut Basswood sheet representing approximately 9inch timbers in 1/48 scale.

The turntable body components are laser-cut microply and laserply.

There are no printed instructions with the kit. pdf will be emailed when shipped. If you want to see them please request using the contact form - no obligation - electrons are free :)

Simple, effective, reliable and affordable.
