gauge question
12. Jul 2010 at 11:51

Abby

I have been looking at information on model scales and track gauges. Tell me if I am correct on this.
Your G1 gauge track is 1.75" or 45mm wide= 4'8" real world or standard gauge. The scale of your locomotive is 1:32 or 3/8"= 1'.
Dan Rowe is working at 1:13.7 or 7/8"=1' so his G1 gauge track still at 1.75" or 45mm wide = 2' gauge in the real world or narrow gauge.

I believe that you said at one time the bore of the cylinders you are making is 1/2" so your bore in the real world is 1' 4".

Working on getting a handle on this whole gauge scale thing

Hi Dave , I have moved your post to a more suitable position.
The gauge / scale thing can be confusing as more than one scale can be run on the same gauge.
In gauge 1 there are two scales , the first being 1/32 full size and the second being 10mm=1 foot , but the track gauge is the same for both , i.e. 45 mm. Locomotives and rolling stock built to the 10 mm scale are slightly larger than those built to 1/32.
The issue becomes more complicated because some enthusiasts choose to model narrow gauge railway stock used originally for hauling slate in North Wales and coal in some British collieries .
Eventually shifting timber and metal ores in the mountainous regions of the US , Australia , South Africa and many other parts of the world.
These are modelled at various scales, 16mm , 3/4" and 7/8" to the foot being popular , but still keeping to a gauge of 45 mm.
So you can see that a narrow gauge model will be considerably larger than a mainline model if the model gauge is constant.
I am sure we have members who can expand on this topic.
As to cylinder bores , these for simplification purposes are not to scale but rather convenience. Depending upon the locomotive being modelled the 1/2" bore could be smaller or larger than that of the full sized engine but some compromises are necessary, boiler pressure being a good example.
Most unseen detail on such small scale is made to work rather than replicate full sized practice.
Dan.

Looks like the cylinders that I am going to get from you will work well for building a donkey engine in 1/32nd scale. Now I will just have to work up a set of drawings to build from. Dave
