Hi
Guys
Regarding
the Shinohara Sn3 trackl there seems to have been a
'shift' in the standards.? The recent stuff is fine
'as is' and all my stock on Rhyd runs through it
quite happily - although the frogs need regular cleaning for
good pick up for short wheelbase locos.? The older points
were tight over check rails but it was a matter of moments
with a 1mm thick needle file to open them out.? These, too,
now give faultless running (and the frogs can get away with
less cleaning!)
All my
curves, under about 42" radius, have the gauge widened
to 14.2mm anyway.? Russel will haul a train of bow-siders
around a 24" curve with no problems although Lew
struggles below a 28" radius curve - but that is more
to do with pony truck clearance than gauge!.
Cheers
David

Hi
Craig,

I have had a go at
comparing the NMRA standard at:
against the O14 standard at:


It looks like the O14
back-to-back (min 12.4mm) will easily clear the Sn3 max Span
of 12.01mm (.473")
and the Sn3 C (CN
in O14 terms) min of 13.18mm (.519") just exceeds the
O14 C (13.1mm max) thus it all should work.

I would be grateful if someone
could check my calculations.

John
