G3S Website

I haven't been able to access the site for the last 24 hours.  Has anyone else the same problem?
A particular question I wanted answering from the standards is the angle on each wheel flange.  Is it 10 degrees either side?

there does appear to be a problem.

Hi Tim,

Yes, it's 10 degrees each side  - but in practice this is very slight.. just the top of the flange.

Thanks Ian, it looked about right so that's what I've got!  I actually took the taper all the way down the height of the flange on the outside, and a bit more on the inside.  Is that much wrong?

Looks as though somebody has forgotten to pay the hosting renewal fees for the website and it has been suspended..... nothing to do with me (Roy was here today and I have mentioned it to him).

John.

P.S. www.Gauge3.co.uk is still active, as it is on my own server, as is this forum and www.G3madesimple.org.uk

If it looks OK Tim - then it quite likely is.

The S01 standard defines the flange depth as 2mm (for sprung axles) and it's width as 1.6mm - so there's not that much metal there to work on in the first place. As a general guide, I'd suggest that you try to avoid a "knife edge" at the top of the flange (as quite apart from anything else - e.g. it will look wrong) it will also be fragile (especially in cast iron - which will chip). Nor do you really want to take too much off the inside of the flange, as the key reference here is the wheel 'back-to-back' (58mm) but I wouldn't worry so much about this, as if you are enlarging that measurement to any great degree - then the flange is probably starting to look a bit odd too.

:-)

So, broadly if the wheel flange looks OK and the back-to-back is right, then I don't think there will be too many problems in practice.
