I just happen to run across this rotating plate that might lend itself as a base for a turntable.





It has a top and bottom plate with steel bearings. 

They also come in a few different sizes.

Any body ever try something like this?

Well, I went ahead and ordered one of these swivel things.
 
Got the 3 inch size. 

Only cost a few bucks so what the heck.





Actually it's just a tad under 3 inches. 

In 1:35 scale a 3 inch wide bridge would be 9 feet, which sounds about right, and would hide the contraption. 

Thinking the length would be about 15 inches to accommodate 2-6-0 & 4-6-0 engines. 

Once it shows up in the mail I'll have a better idea if it's going to work or not.

I used one to build a rotating paint stand.

The only problem was it's too free in rotation!
Mine would spin 5+ times with hardly any push.

A little extra friction is nice.
I stuck some foam to the bottom that rubbed on the table top.

Worked well.

The rotating plate just showed up in the mail.  Quicker than I thought it would. 

This is a tad under 3" square.  It rotates smoothly without any slop, but it is a little tight and does not spin freely. 

Which is fine by me so I don't have to add any kind of retainer to keep it from going crazy. 

Now to cut a hole for the table and figure out some kind of bridge.

Looks great. Be sure to make the bridge a tad longer than the largest lokie you plan to have.
My 2 tables are too short for turning the 2-4-4-2 so she runs tender first half the time!
Derek's plan for a paint stand reminded me of my using one of those 3 level paint bottle storage things given to me by a buddy.
It was a wiggly thing that I didn't use because it was unbalanced with too many bottles.
One day I "kitbashed" it and used the lazy susan base for a painting turntable and pitched the rest.
(including some old funky paint which he gave me also!)

On the TT bridge, you might consider the old Atlas HO bridge girders,
they are 9" long and can be lengthened with a razor saw and glue.
I have used them before. But then, I love old wooden TT's so that's what I have.

Woodie,

What length are your current turntables?  And, how long is that 2-4-4-2?

I was thinking of making the bridge about 12-15". 
I want to make sure that future acquisitions will fit the turntable even though the largest engine I have right now is a 2-6-0.

A 15"'er would be just fine. 12" might work also.
My loco runs as well in reverse as forward, all I did was install a headlight on the tender and a crewman with a bottle in his hand to keep watch.

Quickly...the 2-4-4-2 is a shade over 11" so a 12" bridge would be fine.

Working on the turntable.  Figure the table will be about 15" long. 

Re-building the San Miguel yard with handlaid track and switches. 

Just need to figure out on how to get the table level with the lead tracks to the turntable.

Ah, that's an idea!

Am looking forward to seeing how your project shapes up.

Making a little progress.





Got the turntable pit cut out. 

Working on the pit walls. 

Still need to build the bridge, but it looks like this just might work.

Making progress on the turntable bridge. 

The bridge is 14 inches long, or about 42 scale feet. 

Far from finished but it looks like this rotating plate is going to work.

Si,

Yes, you're right. 

This is in the 'new' San Miguel yard. 


Just finishing up the 'new' borax ore dump,

and pushing to get the turntable into operation,

so that I can resume running some trains.

Howdy Michael, of course the "lazy susan" will work!
My little TT's are just 9" long so what I used works fine.
I do have pit rails and support wheels riding on them so there is no rocking when a loco runs on the table.
You may need them but then the "susan" is larger than mine and it may not need the end to end support.
My tables have "locking devices" which hold the table in position when running on or off.





The pieces for a "locking device"made from sq brass tubing.





And here it is locked, holding the rails in position.
Years ago, I saw a real thing like this on a now long gone tourist railroad.
I thought you'd be interested.

Woodie,

I did something similar to that on a HO layout long ago. 
The turntable was in a staging area and I used round brass tube as a locking device. 

I don't think I'll need it with this rotating plate, but it would be easy to install if I do.

I was thinking that if someone else tries this and gets a rotating plate that spins like a crazy top,
that one might try putting some heavy grease on the bearings to create a little drag.

" Been trying to make some progress on the turntable " 











Hi Michael  :mex:



Lookin' ^^ good on the 'lazy' San Miguel turntable excavation !  :cool:

I'm guessing you stuck with 14" for the deck length ?  ???



:)



Si.

Si,

Yes, the table ended up being just a tad over 14", or about 42 scale feet. 


Once I got the rotating plate fixed to the turntable, and to the bottom of the pit,
I found that there is a bit of slop. 

So I'll be using Woodie's suggestion of some brass tube, to lock the table into place.

That required a trip to the "local" hobby store for some brass. 
I say "local" because it's about a 40 minute drive each way.

Trying to finish the last few things on the turntable, and lay another lead track.

But it's overcast and cloudy, rain off and on, cold and windy.  This is becoming a typical day in Southern California.

When you start losing feeling in your fingers you know it's time to move inside and find something else to do.

I used one with a styrene scribed compact-disc to make a plate turntable.
The "smooth" action was a bit of a problem.
Like trains running at scale speed, it needed to be harnessed.
