try this, they seem to have it in stock.

Hi there, Colombo, where is the turntable at Pickering? Was there a few weeks back (although crowds meant I could barely see anything!) and didn't notice a turntable. Would be nice if they had one at both ends of the line so engines could face the right way round at all times

[Colombo]

Simon,

I know that someone will correct me if I am wrong, but as I recall the turntable at Pickering is beyond the carriage sheds on the LHS on the way to Grosmont.

If it helps

Mark,

Thanks for the aerial photo, that confirms the location of the TT. There is also an image on the net of the Embsay Railway's saddletank, Chadwick , on the turntable at Pickering.

Incidentally, as this string is to do with sheds as well, it gives me an opportunity to mention that the loco shed at Pickering is still in existence, beyond the car park and on the other side of the road to Helmsley. This is a single road structure that was used to house a 4-4-0 together with a Sentinel 0-4-0 that was used to shunt the yard.

To stretch the point a little further, the original goods shed at Pickering, from pre-NER days still stands next to the car park, and I think it may now be a hairdressing salon.

The loco shed at Whitby is still there as well. This large two road stone structure still has it's scissor beam roof as shown in the attached photos. This roof structure has it's origins in NER days, it may not be the original.
The shed doors with the rounded tops are also intact. Presumably it is a listed building. Will it ever agin be used in it's intended form? I think not, because it is very close to housing. However it would make a brilliant carriage shed, for vintage stock.

Yes, Whitby Shed is still there, and as mentioned in the Sir Nigel Gresley - Whitby? thread, whilst at our Scout Group Chairmans boat house, we took a walk (and a row in to Whitby (have you canoed under the swing bridge then?) On the way back we stopped in the car park, and I noticed the engine shed so ran over to snap a pic.

What kind of depth is suitable for a turntable pit in 4mm scale?

[Colombo]

Bass,

By all means build yours freelance if you wish, in which case you could decide that the well should be (say) 4 feet deep. Alternatively why not visit a preservation site and study a preserved example? For example there is a nice one now at Rowsley on Peak Rail.

Just spotted your turntable here Morgan-this is simply the best example I have ever seen,utterly convincing!I'm in awe-again!

Hi rob,
Glad you like it. Here is a another shot of it. Unfortunately not all in focus. The Super D is my work also.
Cheers....Morgan

For "OO" I cannot receommend the Helijan turntable enough.

I am involved with the Engine Shed Road project (see Hornby Magazine December 2007 issue for an article) and we initially used a Peco turntable. However, we were unable to locate or devise any mechanism for locking the 'table in place thus avoiding putting engines in the muck! We replaced this with a Helijan 'table.

The programming is a little involved, especially for a dinosaur like me but its operation superb. All it needs is a little weathering and you're away!

For a shed building, I've used the Metcalfe card kit in both "OO" and "N" but this does look very "Midlandish".

Hey guys, I was wondering if anyone could help in relation to turntables, and I decided against starting a new thread. I'm currently working (albiet very VERY slowly) on a OO layout with a small branch turntable, which I'm scratchbuilding. However, there are some areas I am clueless about, namely:

- suitable bearing units for the main shaft, and where to get them.
- reliable methods for keeping electrical contact with the rails on the TT deck and the contact rings underneath.

Also, I'm a little unsure about reliable methods of supporting the TT at the guide rail ends If anyone with knowledge in these things could please give me some pointers, that would be much appreciated

[Colombo]

Bass,

I used a bicycle front hub for my bearing unit. It is very rigid and almost frictionless.

If you fail to set up your hub exactly at right angles in both planes to the guide rail ring you will get unreliable power pick up, which is why I adopted an alternative method of power supply.

You can use the hub to conduct power to one rail on the deck. I used the overhead power feed on as per my prototype TT for the other.

Thanks for the pointers Colombo The Turntable I'm modelling is a small branch terminus type inspired by the one at Rothbury in Northumbria: http://www.northumbrian-railways.co.uk/ ... e=rothbury

Clearly, the overhead power supply option wouldn't do here. My idea is that, because the turntable need only one exit road (no shed, just turning engines), I could split the guide rail into two sections separating postive and negative, with sprung contacts on the bottom of the turntable bridge to ensure conductivity. Any thoughts?

[Colombo]

Bass,

That Is how I powered my first TT, just as you suggest.

It was unreliable because of dirty track. It would help if you do not fix your deck securely to the axle as this could cause the pick ups to lift off if it is not absolutely square. Rather have a sliding fit that will allow the deck to rest under its own weight on the guide rail.

Rothbury is a good choice. A J21 and a brake composite will make the branch train.
