This kit was developed for the Alton Model Railway club’s OO exhibition layout and takes its bridge design features from the turntable at Swanage. The club wanted a longer version than the original 50ft Swanage turntable so they could turn slightly longer Southern locos.
Turntable bridge length = 228mm. Suitable for tank engines and small tender locomotives.
Easy to assemble. Mostly glued construction. step by step instructions with many photos.
The turntable is designed to use a GW370 powerful 12V 0.6rpm/2rpm/3rpm motor with direct drive of primary shaft turning in oil-bearing bronze bushes. The motor is not supplied in the kit, as it is readily available on ebay, priced £10-£15, 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!
The turntable has sprung plunger contacts for reliable power-routing of the bridge rails – a robust type used by the electronics industry.
The turntable features continuous power-routing for best DCC operation (it is not a split ring design). Polarity can be changed with a DPDT switch for analog DC. Wiring instructions and schematics are included in the instructions.
Bridge rail: the kit does not include rail for the bridge – your own track can be fitted easily within the subdeck using its existing sleepers to set gauge, or you can mount individual rail chairs and rail onto the bridge deck.
The turntable body components are laser-cut poplar ply, birch microply and laserboard. The turntable pit is built up from birch and poplar plywood laser cut parts.
The shaft comes in a pre-assembled subassembly called the “turning plate”. This is is the same proven design as my other turntables with 1,000s manufactured over the last 14 years. The assembly consists of 4mm steel shaft, glued and pinned into a milled brass T piece, mounted on to a ply mounting plate at the centre of the turntable bridge. its completely rigid and cannot slip!
The circular running track (Code 75 rail included) is built up using a jig (also included) that is really easy to get perfectly circular and centred. Yes really! Even a complete soldering beginner will find it simple. 1,000s of customers have done this with my other turntables.
The supporting wheels are double-flanged 8mm diameter 3D printed nylon. These track the circle rail allowing for more assembly tolerance. They fit into the laser cut wheel housings that align them at the correct angle. CAD designed, they sit neatly on the circle rail.
