QUOTE: Originally posted by MisterBeasley How about an old 33-and-a-third record player? It's even called a "turntable." You could mount it below the layout, and just bring up a thin cylinder in the center for the bridge drive. You could use a small motor with a friction drive on the outside, which would give you the gear reduction you want. Or, you might be able to either replace the original motor or gear it down some more.

QUOTE: Originally posted by dinwitty If I dont find a reasonable priced kit, (Bowser has one) I will scratchbuild mine. You just start with a plywood base, circle cut it, drop it down for the pit and go from there. Find a store that sells low speed motors and gears to make a drive for it. Forget indexing, the prototype dont do it, its all eyeballing.
QUOTE: Originally posted by selector Also, and not to quibble, you can't turn an entire train on a turntable unless you use a lot of track an keep one switcher very busy. Only the locomotives get turned, most often, although some cars on a passenger train were turned/relocated on the train. That is why you really should reconsider the reversing loop, particularly if you can make it part of the scenery. All it takes is two gapped ends and a DPDT that you have to remember to throw once the train is fully within the span between the gaps. If you forget, you'll get instant remedial training. [2c]

I have the old non morotized walthers turntabl which needs to be finished to turn locomotives at a cement plants then again I have a siding for the plants dswitcher and cars.
