Product Description


Motor set-up changed to use GW370 motor gearbox readily available on ebay.

With a bridge length of 5" (127mm) this turntable will accommodate most small O scale narrow gauge locos.  (it will even squeeze on a Bachmann Heisler)


* the standard kit has wooden walls.

The optional resin cast walls are very easy to modify to suit terrain.

* running rail - assembled with a jig. really easy. Honest !

* bridge wheel housings correctly align the small brass wheels onto the rails.

* bridge is a simple girder design with wooden crossbeams to carry the rails. Looks industrial when weathered.

The drive train has been changed to use a 0.6rpm GW370 type motor gearbox. These are available on Ebay from many suppliers . typically around £12 or  $15, usually with free shipping. The motor mount, motor screws, and 4mm to 6mm shaft coupler are included in the kit - you just need to buy the motor.

manual control?? no problem! the shaft is 4mm - same as Meccano. for manual set up choose from the very many meccano gear options to suit you situation.

The ready-assembled "turning plate" transfers the primary shaft rotation to the bridge and carries power to the rails using sprung plunger contacts - a robust type used by the electronics industry. the shaft is held and pinned in a milled brass "key" - she ain't slipping!

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

The kit does not include track rails. There are so many options that it is easier for you to supply and fit your own. the kit includes a centralising jig to assist getting the rails central.

The turntable will require a 5 11/16" (144mm) diameter hole to be cut into the baseboard.  (just use the pit base as a template!)

  1. Built up one...ordering a second one ! 5 Star Review

    Finished turntable #1 a while ago, ready to install in layout. This little guy runs like a jeweled watch. Smooth & quiet. Will be ordering #2 when they are back in stock next month.

  2. The 5" Critter turntable is amazing 5 Star Review

    Posted by on 9th Aug 2018

    I ordered the turntable with the stone wall. A wonderful model that works very well. I power it with a 3v adapter. I considered using a voltage control, but with 3v it looks just right. It's not indexed, and that's a good thing. You can roll a small critter or Porter onto it, and send the loco in whatever direction (taking for granted there are rails) you need it.

    I build modules for use on my groups' modular layout. There are two Kitwood Hill turntables on the pair I'm running now. The other is the 54' gallows turntable. I like to let them run, even if I'm not going to run trains. It just looks good.

    It is wonderful. Easy to follow step by step instructions. Alle parts fit without problems. The motor does its work silently and smooth. This turntable is good value for your money and a enrichment for any lay out.! (MK1 deck type)
