Turntable circuitry
Posted by woodstuff on Thursday, August 28, 2008 9:58 AM

HI,

I'm in process of designing a turntable that is approximately 5 inches in N scale. The problem is finding a method to control the table. I'm wondering if there is a circuit that I could build that would propel and index a turntable.

Sort of a cheater method I've seen used in HO scale is to mount an Atlas Turntable with motor below the layout and run a connection up from the Atlas deck to drive your turntable. They're mechanically indexed. By connecting wires from the Atlas Turntable rails to the ones on your turntable, you can also power the rails, with reversing at a given point.

I do not know if you have built it yet, but Atlas sells a 7 1/2 inch turntable for N scale. If you have never built a turntable yet, this might be the way to go. If you have your turntable built, use this one underneath to control. You might find a used one on ebay for less cost.

Sounds like a real challenge!  Here are a couple of links I've found in the past.

Turntable Indexer 

Precision Indexing Turntable 

The Atlas turntable mods seem to be popular too.  Good luck with the project! Thumbs Up [tup]

The Atlas N scale turntable is cheap,easy to operate and set-up,could easily be disguised with some scenery.It,s two disadvantages in my opinion is that it's indexing,although precise and reliable,is fixed at 15 degrees increments so you have to install your trackwork accordingly.It's worst inconvenient is that it is too small at eight inches so my feeling is that you may be sorry to have built a five inch one in the future.

Kevin,
Thank you for the links. the Atlas turn table is 3 inches too big.

I'm not quite sure about the spacing, but I will find that out soon enough.
