Product Description


for 7mm/ft O scale standard or broad gauge (or dual!)

Now set up to use GW370 motor gearbox readily available on Ebay  OR manual operation

With a diameter of 4.5" (115mm) this turntable will comfortably accommodate RCH1923 pattern wagons.

Rail length at 32mm gauge is 110mm.

Rail length at 49.2mm broad gauge is 98mm


MOTOR support.  The motor is not included as are many suppliers on EBAY. Search "GW370 MOTOR GEARBOX" OR "0.6RPM Motor gearbox". cost is typically between £12 and £15, usually with free shipping. The motor mount, motor screws and shaft coupler are included in the kit - you will just need the motor :)

Manual operation. Very simple! The turntable shaft is 4mm. This is the same as Meccano.  A crank to turn 90deg is supplied in the kit.

The rails and deck are built onto a subdeck which hold the 4mm shaft with a milled brass T piece. She ain't slipping!

A PCB under the subdeck carries power to the rails using sprung plunger contacts - a robust type used by the electronics industry.

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. the advantage of this for a wagon turntable are there is no dead zone angles - you can put entry/exit tracks at any angle.

The standard kit now has FOR 32mm GAUGE ONLY a ready soldered track assembly that keeps the rails central with Peco Nickel Silver code 124 rail ready to drop into the subdeck.  If you are a broad gauge modeller (or wish to DIY) then I will only supply the PCB ties leaving you to supply your own rail and solder the rails in place yourself.

Obechi wooden deck planking has engraved planking (scale 8 inch planks) and bolt holes. Nothing looks like wood but wood!
