How To Make A Turntable Drive Mechanism

How to make a model railroad turntable drive mechanism.

This takes you through the process of building the drive mechanism .

 

This mechanism uses a geared down high torque 12 v DC motor.  Control indexing of that motor as you wish.  We, however use an indexing control circuit that you review at DIY Turntable

Turntable Drive Mechanism Materials Required

  • Gears – Get gears here. Actobotics
  • PVC pipe to make mounting plates (you can also use sheet steel, sheet aluminum)
  • Threaded rods with nuts.
  • PCA glue

Procedure

Prepare your mounting plates.  We use PVC pipe shaped using the procedure that you see here. Bending PVC Pipe

Insert your slip ring in the bottom plate.
