Scratchbuilding a turntable - HO Scale

ShareThis

Hi all

I am going to need a small turntable for my new RR and would like to have a go at scratchbuilding it. Can anyone offer any pointers to others that have fully scratchbuilt a reliable turntable? Any good articles floating around?

I did read the article here on the turntable & roundhouse but the author used a commercial TT kit so I am hoping someone may know of a total scratchbuilt resource for TT's

Cheers

Bruce

What style of turn table do

What style of turn table do you have in mind?  A wooden gallows turntable using the armstrong method for propulsion? A big honking modern (relatively speaking) with a concrete pit and compressed air drive?  Something in between?

Cheers,

Here is one I know of...

I can't vouch for how good it is or anything, but here is the link.  Turntable Mechanism

I used to know of another turntable tutorial that was more detailed.  It used a Geneva Mechanisim as the heart of the drive system.

Here is a Geneva Drive discussion from another forum.

Here is the one I was looking for, Geneva Drive Turntable

Scratch building a turn table

Bruce      Try googling Build a model train turn table and you will find quite a bit and step by step articles

                on building a turn table. Hope this helps.               ron netti

Hi Charlie Mine will be sort

Hi Charlie

Mine will be sort of a backwoodsy, set in the early 40's, branchline terminal type turntable, definitely nothing fancy. I model the Appalachian region of Virginia based loosely on the Interstate Railroad. In one of my Interstate books a pic exists of one of their turntables that is pretty basic. My main use for the turntable will be to purely turn locos - it will have 2 exits only, one to the engine house (single stall) and one to a track beside the house. Trains interchange at my town and the engines will need servicing and turning before heading back to whence they came.

Thanks ron & 14869, That

Thanks ron & 14869,

That mech looks beyond my construction abilities but it *is* nice! I am still deciding on the drive mech - manual or powered. I have an old stepper motor from one of those air conditioner like coolers (they use water & a fan - can't remember what they are called!) so have been thinking of doing something with that.

I'll jump on Google and see what I can find...

Cheers

Agreed!

Yes the Geneva Drive System is an engineering wonder.

I have always liked the turntable mod below.

As an inexpensive, fairly easy alternative to scratchbuilding a turntable, what about customizing an Atlas Turntable like this one from the 2Guys how-To's?

For my H0n3 turntable I want

For my H0n3 turntable I want a manual device for a manual driven turntable.

For power I've made a PC board plate, and wipers at the bridge.

I just looked at Jim Marksberry's turntable tutorial.

Great idea for using an inexpensive Atlas as the basis for a kit bash with a pit.  I would add one more idea to his plan.  If you check out a craft or sewing store, you can find perfectly round wooden embroidery hoops that will make nice round pit walls if you get one of the correct size.

I always thought so too.  I was surprised by how great the humble Atlas turntable could be made to look without too much difficulty.  I have also heard that while inexpensive, the Atlas turntable indexes very well.

The embroidery hoops sound like a good idea too.  Making a note...thanks.
