Product Information



Our base product for OO and N gauge indexing turntable is based on a 70 foot turntable. This product utilises the 'bridge' and 'well' from a commercially available product.


This product is supplied with bridge handrails and grids for the well. These are not fitted to prevent damage during transportation and to provide the option for customers to fit a more detailed handrail if preferred.


We also produce drive systems to fit Kitwood HIll Model turntables which can be purchased with an adaptor for ease of installation.

The Adaptor Ring Kit


We recommend, but it is not essential, an adaptor ring kit for either the OO or N gauge turntable units.The main advantages being it allows you to :


  • to remove the complete turntable assembly from underneath your baseboard without having to disturb track-work. (The track-work sits over the edge of the well.)
  • to raise or lower the turntable assembly to ensure that the bridge rails are aligned correctly with the baseboard rails.


These consist of 2 pieces of CNC machine cut 12mm MDF.

  • Piece 1 - The OO version, due to popular demand, is now 18" square and the N gauge is 11" square. Both have a CNC machined hole in the middle which is the outside diameter of the lip of the turntable 'well'.
  • Piece 2 - is a CNC machine stepped ring which the turntable unit fits into. This is held in place on the underside by means of 4mm countersunk bolts, washers and wing nuts.

To remove the turntable unit, you first have to disconnect the wires from the PCB under the turntable, then undo the wing nuts. The complete unit can then be safely removed from underneath without having to disrupt any of the track work.


Both versions have the facility to adjust the bridge rail height with the height of the tracks to achieve a smooth prototypical transition. This also allows for easy adjustments if tracks are laid on a cork base.


If purchased, instructions on how to fit the adaptor ring kit are provided.



PRICE:  N gauge £50.00 plus P&P where appropriate (no change in price anticipated)

              OO gauge £75.00 plus P&P where appropriate (no change in price anticipated)
