Product Description

7mm O scale 40ft deck turntable kit


3 weeks from order to shipping

This small turntable with 11.25" rail length is perfect space saving for small layouts, capable of turning a wide range of small standard gauge locos. Its full wooden deck is from the Victorian/Edwardian era but some of these saw service until the end of steam.

Like all of Kitwood Hill Models turntables this is mostly plywood construction, only requiring glue to assemble. Soldering is restricted to the circular support rail, and wiring the track rails. 

Construction is straightforward, built up in sub-assemblies, with many pictures in the instructions.

PIT features

* Pit uses the tried and tested 11.25" On30 turntable pit. The pit base is made from several layers of ply glued at 90degrees to give a rigid structure.

* The pit running rail is included, along with a simple assembly method, proven on our many On30 turntables. Its so simple a novice builder should be able to obtain a perfect circle. That said, the wheels are wide enough to accommodate a reasonable amount of assembly tolerance.

BRIDGE and deck features

* The 3mm ply bridge frame forms a rigid structure carrying wheel assemblies and top sub-deck. The full deck is re-enforced with an outrigger frame.

* wheel assemblies are designed from new for this kit to ensure they can carry the extra weight of O scale standard gauge locos. The kit no uses  strong Nylon 3D printed double-flanged wheels that run on steel axles. CAD designed features hold the double-flanged wheels exactly on the circle rail.

* The deck surface is engraved with scale 9" planking complete with boltholes. Maintenance hatches are included to the design.

* The kit includes lifting push poles. I thought it worth including the parts for these, although it is easy to fashion your own (we are modellers after all)

* Bridge track rails and chairs are now included as standard - 44off rail chairs and Peco Ni-silver code 124 rail. They are great looking parts and really easy to use.  Note this is no good for German Lenz - its for UK steam.

Instructions: These are available in pdf only. There are no printed instructions in the kit. The instructions are full of photos taking you through the assembly process. If you want to see them before buying then please ask on the contact page.  No obligation, electrons are free!

Drive train features

* Track power is taken to the rails via KHMs well-proven robust turning-plate assembly - which also holds the 4mm primary shaft . This pre-assembled item includes continuous PCB contact rings for the best use with DCC. If used with a DCC reversing module, DCC loco decoder power will be continuous. The track power contacts are hard-gold-plated sprung plungers of a robust kind used in the electronics industry. Each rated at 6A. The primary shaft turns in oil-bearing bronze bushes.

* The kit uses a proven drive train designed for a very capable 0.6rpm motor.  It has plenty of grunt to turn the locos you can fit on this small deck. THE MOTOR IS NO LONGER INCLUDED! it is readily available on Ebay (and sometimes Amazon). Search "0.6RPM gearbox motor", or "GW370 gearbox motor" on Ebay and you will find many suppliers. The motor is usually between £11 and £15 and often comes with free shipping.

* Indexing is completely foolproof...and free...track alignment is by eye! The motor can turn extremely slowly so its easy to stop at the right place. Its a small turntable and likely to be installed on a small layout - so "visual indexing" is good enough for 99% of users. That said...I have an adapter for ADM's most excellent indexed drive system. Possibly overkill in most applications of this turntable - but if you have many exit roads, an ADM drive system is fantastic play value!
