So how come this person is allowed to trade at the Scale4North?

We know of many tales of taking money and refusing to re-fund and also County Court judgements against him.

Re: Flange thickness-effect of.

In fact, the P4 profile drawing is not really any use, as it lacks several critical measurement setting locations that are on the EM profile drawing. Jol Actually it doesn't need them as the various circles are tangents to each other and therefore calculable as regards the position of their centres...

Not knowing the corner radius of the rail would bring the same uncertainty to P4 in just the same way.

An email was sent to Colin this morning who answered that the EF of his EM wheels is a commercial confidentiality.

Re: Brettell Road

Which way do you think the ejectors point on a 94xx tank Noel? If you mean the ejector exhaust, it goes up the chimney so far as I know, Jim. Cylinder drain cocks and regulator open would probably produce enough steam to blot out quite a bit of the picture, so the steam is presumably a minor leak f...

Re: Engineering, Injuneering and Knitting

Re: Making a Start - The Peak District Midland / Monsal Dale pre 1903

More importantly, fishplates were cast, and cast iron/steel can't be bent like that. Rail end joints are subject to high levels of alternating stresses, so rolled wrought iron track would presumably have required rolled wrought iron fishplates, as cast ones would not have coped with the stresses.

Re: Printed buffers for wagons

Based on a Slater's buffer: Distance to buffing face = 6mm Really? Seems a bit short. Perhaps I wasn't clear in my picture; apologies. The distance in question is from the front of the front of the buffer head to the base of the wide bore. If 6mm is the depth of the wide bore in the buffer guide, t...

I'm not entirely sure what the springing conventions for 7mm scale are either. I'll have to do some digging... Otherwise I'd be interested in being the guinea pig. I'll have a dig around.
