Hi All,

I'm going to assume that I may set up my turntable to be powered by a 3 cell LiPo battery,

that I have and have found to be to large to fit in any of my locomotives.
    
Thoughts??


Rick

Howdy Rick, if the Walthers TT motor is a 12 volt job then the answer is YES. 
I am not familiar with the model myself.
If it does not have indexing but turns slowly, you might be able to "cheapout" with an old r/c car receiver & transmitter to operate it. 
If it has indexing then it might work OK then also. 
Years ago, I powered an old Atlas HO TT (converted to On30) with the same setup.
Good luck

Woodie

Hi Woodie, 

Yes, I was thinking about using an off and on switch from the new Rapido switch machines I recently purchased 

(switch moves LEFT and RIGHT, yet springs back to a middle detent OFF position) 

because when I connected the 90' Walthers turntable to an old transformer, it turned quite slowly. 

But I see your point about the need for a speed control component.

OK then, you just need the 11.1V battery and a simple DPDT with center off to control direction, start & stop. Nothin' fancy.

So, I broke down and bought a beat up, old but at least small transformer from the junk pile at my hobby store and am using it to power the turntable. 

Built a mini shelf into the facia. 

No big deal. Working well.

Hi Woodie,

Yep. Decided to solve the problem fast and move on to other more pressing issues.  :)  But whatever.

Wish the turntable moved a little slower than it's stock speed, but not much I can do about it I guess.

Remember those old "pulse" transformers? One of those maybe would have had a slow down effect on this table.

Cheers

Rick
