Another idea I am looking at is wagon turntables. Just wondering if there is a standard length for railways in UK.
I know the kits I have seen for HO ones are longer. There was a mention of these in MTI a few years ago.
If there is not a standard length I will work on what fits in best.

I should imagine (this is just a guess) that the 'standard' UK length would be to accomodate a typical 4-wheel wagon with a 9' or 10' wheelbase?

I'm pretty sure that Jordan is right and that most wagon t/ts in the UK would have been to fit a nine or ten foot wheelbase wagon.
I have read something about it somewhere but typically can't remeber where.
It may have been in one of Bob Essery's books on railway operation.

I figured it would be just big enough for a 9ft of 10ft wagon, but by how much. would that be an extra foot each way, so say 12ft diameter, which is close enough to 50mm say, or would it only just be long enough, say 11ft which is nearer to 45mm. I know I have seen a drawing in magazine .

I am working on track items. Only pictures are those I either generate using CAD software or the Shapeways page.
Latest offering is a small wagon turntable, with different surrounding parts, ie small, big and giant stone surface.
Assuming the link works they are in the wagon turntable section.

Generated pictures here





The actual turntable is 48mm diameter, the surround are 67mm each side to fit setrack geometry. Plain topped turntable, plan to add wood type top as well.

Simon - you might like an add-on for your turntable, to fit longer wagons http://reseau3gg.r.e.pic.centerblog.net/b1be8ec4.JPG or perhaps this http://reseau3gg.centerblog.net/voir-photo?u=http://reseau3gg.r.e.pic.centerblog.net/o/ed14ef1d.JPG

Nice idea, but I think I will just make a longer turntable. the 32mm gauge one with 16.5mm will suit both narrow gauge and HO/OO 16.5mm gauge.

Visited exhibition today, talking to EM workshop chaps, showed them my wagon turntable, they asked if I could do one for EM(18.2mm) gauge, which I have just done.
I am now thinking about 21mm gauge for Irish railways, but what is standard length, as extra gauge means turntable will need to be longer, unless wagons are less than 10ft length. Anyone know length?
------------------------------

I suspect they were still only 12ft long. A 9ft wagon still fits OK, a 10ft one just about.

Thinking of Ireland, I believe there were some dual gauge 5'3" & 3'0" around.

One of these at Strabane on the County Donegal was used for a different purpose to normal. There were number of wagons equipped with winches at one end to allow the wagon body to be transferred from broad to narrow gauge wagons and vice versa. One wagon was placed on the turntable and turned so that the correct end faced the other one which was shunted up to it, and then the body winched from one to the other.

interesting idea, but I think I ill stick to single gauge turntables for the time being.

Just working on a base for turntable, incorporating the corner pieces as well as a mechanism to operate turntable from side. Once I have a sample I will post a photo as it is difficult to describe in words.

21mm gauge wagon turntables now designed. can be used for either 3ft gauge in 7mm scale or 5ft 3in in 4mm scale, but not both together!
Will now have to expand 21mm range then add 12mm gauge range.
Never ending, but at least once designed(and tested) there is no more work for me to do.

found a picture of the mixed gauge turntable in Ireland on this website
http://www.donegalrailway.com/cdr-signalling/

I have now built up a couple of he working wagon turntables. The idea is so simple I can't understand why no-one has done it before.
Awaiting some samples with slight mods(I managed to work round these small problems), and have even attempted a 9mm gauge version. The 48mm long one is just a small mod on the 16.5mm gauge version, but the 24mm long one is very small, and in theory should be OK, fingers crossed.



Here are the first two ones. A 48mm diameter one on the left ideal for OO with the smaller stone surface, and an 84mm one on the right with 16.5mm track for narrow gauge with larger stone surface. The 84mm one was initially designed with 32mm gauge track.
The operating arm is at bottom and slides from left to right. It is deliberated set part way on OO version to demonstrate this.
On each turntable one route is 'live; and can be connected permanently, so locos can travel across turntable. As the turntable only ever moves 90 degrees this is possible without wiper contacts. In some ways is is more a sector plate as turntable never turns full circle.
Just have to remember which way it is set.
I am designing a small boxfile layout to show off not only the turntable but also some 9mm gauge track pieces.

At Bournville exhibition on Saturday, I was asked if I could do a 6.5mm gauge version of my wagon turntable. I have just done the designs and uploaded them and they are available here
https://www.shapeways.com/shops/recreation21?section=6.5mm%28z%29+gauge+track&s=0

As they are based on designs that print OK, these should also print OK.
