Re: Best wire for collectors

I seem to recall that Mike Sharman reckoned there was some adverse reaction between phosphor bronze current collectors and steel tyres, but I regret to say that I cannot recall exactly what caused the problem. I have successfully used hard brass wire bearing on the edge of the steel wheel flange, a...

Re: Clearance for CSB wires

What vertical clearance is required for CSB wires without impeding the suspension? I am trying to arrange frame spacers in a diminutive 0-6-0 prototype that uses High Level hornblocks. Am I right in assuming that the lowest position on the High Level CSB jig ('A') would automatically require trimmi...

Re: SR fence posts

Of course you do realise that the wire isn't supposed to go through the holes in the fence posts. True but as I remember it, the main wire was held in place by a short piece of wire that did pass through the post and was then bent round the main wire either side of post. Modelling that would be fun...

The key factor here is always the "rate of change in cant". Where Cant is the difference, at any one point, in the hight of the rail top between our two rails, and the rate of change is expressed as the ratio between the change in cant and the distance over which it occurs. You may get cha...

Re: Bill Bedford Coach Bogies

Agreeing with Keith and Guy. You can solder the wire to the bearing carrier if need be, though most find it unnecessary, but not the end of the spring to the end support. I would have thought that soldering at the centre would also cure any tendency to pop out at the ends?
