Product Description

On30/On3 11.25" TURNTABLE KIT

CHEAP MOTOR IS NO LONGER INCLUDED. They are available on ebay. Search for "0.6rpm motor gearbox"

An 11.25" bridge length version of our very popular 9" On30 turntable

11.25" is just enough for a Bachmann On30 2-8-0 consolidation.

On30, On3 guys - please select On30, On3 from the buttons.

HO guys.  This comes in at a scale 82ft in HO. I do have HO modifications, and fortunately the On30 pit is suitable for HO - but please bear in mind I cant change the wheels - they are a bit big.

OO guys - This is not for the British OO market!! its N. American, it has cross beams on its girders. A self-respecting UK pacific steamer would be not seen dead on it. Please find an another supplier who does 70ft OO turntables - dont bodge this one!

The turntable is designed to take a GW370 style 0.6RPM motor+gearbox. (£10-15 on ebay usually with free shipping)  The motor itself is not included, but the motor mount, screws, and shaft coupler is. This high-torque low current motor is rated at 0.6RPM at 12V and is directly coupled to the shaft.  Its best to run it from a DC variable supply, (or DCC loco decoder) so it can be reduced in speed to "extremely slow" for easy alignment with the tracks

Operationally the turntable has sprung plunger contacts for reliable power-routing of the rails - a robust type used by the electronics industry.

The turntable features continuous power-routing (not a split ring design). Polarity can be changed with a DPDT switch for DC(or DCC) use, or a DCC reversing module can be used to ensure continuous operation of a sound chip. if you have DCC, a reversing module or dual frog juicer is the best bet. wiring instructions and schematics are included in the instructions.

The kit does not include bridge track - your own track can be fitted easily using its existing ties to set gauge, or you can spike your own rail in place. The version of gauge only affects the decking widths.

The turntable body components are laser-cut poplar ply, birch microply and laserply, with laser-cut bass crossbeams and a deck surface of laser-cut basswood representing approximately 9inch timbers in 1/48 scale. the kit has handrails made from piano wire to keep them robust and perfectly straight.

The circular running track (code 75 rail included) is built up from a jig (included) that is really easy to get perfectly circular and centred. Yes really! Even a complete soldering beginner will find it simple.


Supporting wheelsets are 12mm double-flanged wheels that track the running rail without falling off. they are wide enough to accommodate a fair degree of "assembly tolerance"  and fit into wheel housings that ensure they are aligned at the correct angle and sit centrally on the rail.

The 11.25" turntable needs a 11 3/4" hole.

The pit depth is just over over 2 1/2 scale feet in 1/48scale (16mm) at the pit wall.

Overall depth from the track base is 3 1/2", including motor.

Pdf Instructions will be emailed to you soon after ordering. If you want to see them first to get better idea of the kit please contact me - no obligation, electrons are free :)

Simple, effective, reliable, affordable.
