On30 54ft Gallows Turntable

On30 13.5" (54ft) Gallows Turntable kit.

THIS KIT IS DESIGNED FOR "DIRECT DRIVE" FROM A GW370 STYLE 0.6RPM GEARED MOTOR. 

FROM APRIL 1st 2023 THE KIT HAS NO MOTOR!!! 

MOTOR IS READILY AVAILABLE ON EBAY FOR AROUND £10 to £12, usually with free shipping. (Also sometimes Amazon)

KIT INCLUDES A SHAFT COUPLER, and MOTOR SCREWS,  BUT NOT THE MOTOR. You will have to buy that yourself.

Please note: I ship at cost but this is a heavy kit with a shipping weight of 1.4kg.

On30 and On3 options - please select.

13.5" Will turn the largest On30 RTR locos to date  without any overhang.

Bachmanns biggest loco is the 4-6-0. 13.5" long. KHMs 54" gallows length and loading gauge is built with this in mind but it takes all the other Bachmann On30 locos with ease.

The design is similar to the Laws turntable.

The bridge is not just a bag of sticks. It is built up on a integral jig making for easy alignment. All parts that require angles, cutouts, cross joins are laser cut from  basswood to ensure the correct size, alignment and make assembly straight forward.

Gallows bridge detail includes laser cut square nuts and  several sizes of washer as well as stays, stay saddles and stay ties.

The spider is simple and effective. Rather than create a complicated mechanism that costs a lot but cant really be seen, I have "suggested" the spider ring, and this allows me to use KHM's standard turning plate and pick-up assembly methods within the "spider space". That way the kit is able to draw on the proven performance of our other pit turntables.

The shallow pit base is made up of 3 rings, carries a support rail around the edge and includes the pitwalls. The pit base of the 54ft version is bulit up from 3 one-piece rings assembly self-jigged with alignment aids.  The pit can be supported by the rim around the top of the wall with a circular hole in the layout top.

The bridge wheel assemblies are the 4th incarnation of KHM's turntable wheel "technology". The angles are set by the assembly - its almost foolproof! The double-flanged wheels "track" the circle rail without falling off.

Below the pit floor, the turntable is designed to use the powerful worm-gear 12V 0.6rpm motor with direct drive of primary shaft turning in oil-bearing bronze bushes. The motor is no longer supplied in the kit, as it is readily available on ebay, but the kit does include the motor mount, shaft coupler, and the motor screws. all you need to buy is the motor - or turn it by hand!

Bridge rail: for this kit I have decided not to include any bridge rail. several reasons for this but mostly because its so easy to fit. If modelling in On30 then Peco SL100 track (or HO code 83) ties fit neatly between the jig rails. In all cases the rail sits on the crossbeams.

Bridge deck has On3 and On30 options. with planking and bolt holes engraved.

Assembly is straightforward and broken down into sub-assemblies. The kit is packed with this is mind, each sub-assembly having its own pack.

Instructions are mostly photos with lots of angles to take you through the build in a step by step fashion. sadly the website is not playing ball just now so I can't put the instructions up here yet. You will be emailed pdf instructions when I ship the product. If you wish to have a look before purchase then I'm happy to email instructions without any obligation. Electrons are free!
