Product Description

65ft O scale (7mm/ft scale) turntable kit.

This kit is great for turning your large 4-6-0 locos. Fit for a King (or indeed any GWR loco)!  It picks up generic features found across the UK, rather than focusing on a particular prototype.  For the largest Pacific UK Locomotives (A3/A4, Duchess, Princess etc) you'll need the 75ft turntable 

Assembly is straightforward with step by step instructions with many photos. No need for clever solder skills it really is for the "average" modeller. Kit comes all the needed electrical contacts for the bridge and is "DCC sound friendly" - no gaps in supply!

 bridge dimensions

65ft 7mm/ft bridge diameter = 455mm

bridge track deck width = 47mm

deck width between handrails = 91mm

Pit dimensions:

Outer rim = 487.5mm

hole required = 475mm

pit depth:  31mm at centre, 25mm at edge


Drive train options:-

Hand from heaven!  In most basic form of the kit turning is hand from above using the push poles.

"El Cheapo"  The 0.6rpm motor I originally released with the kit will turn the bridge just fine with the free-running 28mm wheels. BUT....its a very cheap motor. It has backlash. That means the motor itself will not hold the bridge still - that relies on friction elsewhere in the system. I have sold a lot of these 65ft TTs with "El Cheapo" and many modellers have made it work for them.  I NO LONGER SUPPLY THE MOTOR BUT IT IS AVAILABLE ON EBAY. search "0.6RPM motor gearbox" or GW370 motor gearbox" on ebay. They are £10 to £15 with several suppliers and usually free shipping.  its worth giving it a try - given that the other options are at least 15 times the price! the mount for it, and the 4mm to 6mm shaft adaptor are included in the kit.

GREENWOOD MODEL RAILWAY PRODUCTS. manual motor. Mike Greenwood now has an adapter plate for Kitwood Hill turntables which allows you to use his turntable drive systems. This is based around a stepper motor and 3 gear toothed belt reduction. I have the manual control version. it is a quality ready-assembled unit and runs really smooth. The manual control version is with simple a push button. You will have to order the unit from Mike. (£165 for the manual system as I type this) https://greenwoodmodelrailwayproducts.co.uk/

ADM Indexing system  Alastair at ADM has retired in Dec 2022, so these excellent drives are no longer available. If you pick one up second hand I do have an adapter for it.

DCC or DC. Like all KHM turntables can be used with either system. The track power PCB connection rings are continuous so there are no disconnects to DCC decoders with sound as the bridge turns. The contact plungers are 6A rated quality items from the electronics industry. Polarity can be handled with a DCC reversing module or a simple DPDT switch for DC.

Primary shaft turning plate: the heart of all KHM turntables and proven design. This is a jig-built, ready-assembled item with the 4mm primary shaft pinned and epoxied into a milled brass section. She ain't slipping!!

Assembly and construction:-

Bridge is made of laser cut ply of various types and thickness with hardwood decking. Glued together with step by step photo instructions. Not hard. Novices have built my turntables!

Bridge track: for UK and Australia chairs are included for Peco code 124 rail..  Note this will not work for Lenz locos which require a taller code rail. European modeller will have to supply their own. 

Pit is laser cut 3mm and 4mm ply. Because of the weight of locos it is best to support the turntable from below, rather than the rim (unlike other KHM turntables)

While the kit will make up a whole pit with base , because of the size it is strongly recommended to fix an additional flat rigid 9mm ply surface to the underside to maintain rigidity. This isn't in the kit because that would weigh far too much and be too big to ship!

Ring rail:  Code 100 (included) is soldered to PCB sleepers and a simple jig helps you get it circular and set in the right place. All KHM turntables use the method and its well proven over last years. It is simple, even for novice solderers.

bridge wheels: Now 3D printed with ball-race bearings.  28mm diameter. They are wide enough to be forgiving of "assembly tolerance" of the ring rail.

INSTRUCTIONS ARE NOT PRINTED. This would be high cost, and heavier to ship. This way I can include very many photos. The PDF files are emailed to you when the kit is shipped. If you want to see instructions to help your purchasing decision then I happy to send without obligation. Electrons are free!  Just contact me by email at sales@kitwoodhillmodels.com.

  1. Turn to perfection 5 Star Review

    Posted by on 11th Apr 2018

    Having spent months working on sourcing a turntable for my newly constructed 0 gauge layout, I came across 'Kitwood Hill Models', after a detailed discussion with Simon he offered to produce a turntable that would suit my requirements of a 65ft version. The result is superb and fits into my scheme perfectly. This table comes with good built instructions and works like the real thing, well pleased. At £95 this table is a snip as other makes come in at around £260.

  2. O gauge turntable 5 Star Review

    Posted by on 8th Apr 2018

    Really impressed with the kit it has gone together a treat, works well and runs/turns smoothly and slow. I am building an o gauge round house and it looks good, just need to paint and weather.
    Well done on a great kit at a good value price.
