Since the turntable doesn't want to stay exactly in place,

I installed a brass slide lock, to keep it from wandering away from alignment.





It's a cheap and easy solution.

I wanted to add some final thoughts to this thread.















Cost: 
the plate was $3.00, the square brass tubing $5.00,
and estimated cost for the basswood and brass about $7.00,
for a total of $15.00

Not bad for a turntable. 
It's located outside so motorizing it, or adding indexing just wouldn't work.

Overall I'm very pleased with how well it works. 
Would like to hear from others that may have done something along these lines.

Great idea on the slide lock, I need to do that for my two turntables!

I wonder if a magnet(s) would work to lock it in place yet not show?

I don't think it would be too hard to use an electromagnet,
like a Peco point motor, to lock in the pin from under the bridge.

Maybe a spring loaded locking pin, that can be released by an electromagnet.

I have very strong electromagnets that were used in telephone exchanges,
from many years ago, that would be ideal.

Will post a pic when able to.

Peter,

An electromagnet would probably work.

Many years ago I worked for Pacific Bell.  Wish I had some of the stuff we were throwing away.

Fleischmann's H0 turntable used a spring-driven locking pin,
that engaged with indexing slots in a cog-wheel running along the pit's rim.

It was held back during travel by an electromagnet.

I remember a DIY turntable article in a mag of the early 60's,
where the same principle, albeit pin and holes, was used.

High Tech "indexing" is a neat way to locate a TT...
but I am old school and like me, my TT's are "armstrong" (or fingerstrong) manual jobs.
Of course, my TT's are close to the edge of the layout and are easy to work,
and the sliding "pins" keep the alignment right.
Years ago I used an old ATLAS HO scale turntable on a Texas Outlaw On30 module and it worked great,
even though some guys thought the growling motor/gears upset their hearing chuga chug and woo woo sounds.
Oh well, "you can't please everyone...so you gotta please yourself"-Rick Nelson.
