Using Zamzoodled couplers with 21mm gauge stock

 

Hello,

Has anyone used Zamzoodled couplers with 21mm gauge in 7mm scale to represent 3ft gauge; or with scale metre gauge?

Is there a standard coupler centre height above rail level for gauges wider than 14mm gauge?

I am modelling some small items, initially a Ruston 48DS followed by some wagons. I am not modelling a specific line. Scale drawings show quite a lot of variation. The only actual dimensions I have come across are Clayton's drawings of the Southwold locos and these vary between 2'7"3/8 and 2'8"1/2 for two locos. I understand the Irish lines had quite a lot of variation between them. The Isle of Man system must have a standard height and Boyd's 4mmscale drawings indicate 2ft centres.

I am just looking for a standard I can use and if one doesn't exist I will probably go for 14mm above rail height ?

Any advice appreciated.

David

David,
Coupling height above rail is what ever your railway or any railway adopted according to there needs obviously when it comes to 2 foot gauge it was generally the norm to try and have the coupling height as low as reasonably possible.
I would suggest taking a look at what prototypes used in your chosen gauge and go with an average of the height they used.

David,
As Brian says, it'd down to your prototype (if you have one), or you can buy the ZZ height gauge. I'll post a photo of it in action.

Of course as soon as I sent that I realized the ZZ height gauge would probably not be wide enough for 21mm gauge (and certainly wouldn't centre) but you can see the principle in my picture (posted in Chelfham O14).

Hi David

I had an order 6 years ago for a custom height gauge for 21mm gauge with a 12mm centre height. These are all produced to order so can be any height you like within reason.

John
