G'day All,
I have heard it said that Romford 14mm gauge axles are actually 14.2mm
gauge for Sn3. According to John Clutterbug's recently posted standards info
(in the files), there is an extra 0.1-0.2mm back to back on Romfords.
Does it make all that much difference? I haven't laid any points yet, but
the track I have is laid to 14mm exactly (even around 6" radius curves) and
the Romfords track fine around it (I come from N using proprietry track so
am unaware of the intricacies of handlaid finescale track).
From what I can tell (left my calipers at work), its only the flange
thickness that is different from the RCL wheelsets. If it does make a
difference, would it be a good idea for us all to send our axles back to
Romford saying they aren't to the right gauge and asking for suitable
replacements?

Hi Mark

Over the last few years I have read many articles about obtaining good
running and all seem to imply that following consistent standards is
vital, especially through pointwork.

I dont know what exact impact the extra 0.1 - 0.2 will make in
practice but it will have a corresponding effect on check to flange
and check to gauge (see Files - standards). These I know can have an
impact as the wheel is likely to hit the crossing nose and therefore
can derail.

Regards
John

Mark,

Your comments are interesting but gave me quite a start. If the "14mm Romford axles" are actually 14.2 mm gauge they would also be dead-on for 3mm Finescale. Being a member of the 3mm society, I would think that there would have been a lot of interest had they actually been 14.2 mm gauge. Wheels have been a concern for the 3mm Society for a while and I don't recall any comments about them in the Society newsletter but I may have missed it.

The other explanation is that even if they were 14.2 mm, the wheels wouldn't have been very useable in 3mm due to tire width and spoke count.

Just another perspective on this. Thanks for mentioning it.

Matt

Frank,

There is probably quite a bit, but the 3mm Society, like most UK socieities can only sell to members. The society price list is:

But, as I mentioned, you need to be a society member to buy. Three Millimetre Scale Railways (3SMR) and Finney & Smith are both commercial companies which offer some 14.2 wheels.

All the 3mm drivers use a shouldered axle for back-to-back spacing but the wheels are simply pressed on to a straight axle.

In looking for items to be of use in 7mm I would suppose the solid wheels would be more useful than the spoked.

Matt,

Let's look at this the other way round, what is there in 3mm wheels
which might work in 14mm narrow gauge?
