Hi Phil,
There are some pre-sets in Templot for 5ft-3in gauge, although you can of course set any custom standard you wish:
View attachment 1732
It doesn't include the standard you mentioned because I regard it as flawed, although I may add
EM-SF(I) to take advantage of the Exactoscale 0.8mm check-rail chairs.
The golden rule is that to use an exact-scale track gauge you must also use exact-scale wheel profiles and flangeways, otherwise the wheels won't fit behind loco valve gear, inside splashers, behind axleboxes, etc. All H0 models are over scale width in the running gear for this reason. To use overscale wheel profiles, the track gauge must be reduced slightly if you want a scale-width model. Hence EM, 0-MF, etc.
As you probably know, there is about 20 years of my modelling life in the 21mm
Adavoyle Junction layout -- although I recall spending most of my time working under the baseboards rather than on top:
The pointwork was mostly built by Peter Taylor in 1983, with some contributions from the earliest beginnings of Templot. It's been in my thoughts recently because it was fully chaired riveted plywood -- we chaired it by injection moulding chairs in situ around the rivets using a hot-glue gun. I remember spending several evenings on the spark eroder making the injection tools. Joe Brook Smith was delighted when I showed him the chairing process at Scaleforum in 1986. I wonder what he would have made of the resin-printed chairs I made this week? The layout spent about 20 years on the exhibition circuit, and is now in the care of the South Dublin Model railway Club.
