Re: Solder paint

It may not be entirely relevant, but I have had a tub of Carrs 188 solder paint for many years. Some years back it had gone fairly solid, so approached Carrs for advice, and was told to use Carrs Green Label flux, which certainly worked at the time. I've never used Green Label for anything else, and...

We used to leave pennies in a glass of Coca-Cola overnight and in the morning they were like new. I now know it was the phosphoric

I have, and it worked well on curves down to about 1m radius. There's always the wee bit at each end which has to be discarded, but that's no matter

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

I think a wire torque reaction link is ideal but it needs to be fairly long so that any movement of the axle is as near as possible straight up and down. This can cause problems fitting it round everything else. I do feel that a very little movement can give the jerk needed to start a slightly stick...

Re: Road and platform surfaces

Hardwood "cobblestones" were, I think, used in towns and cities which were otherwise surfaced with granite setts. The purpose was to make the traffic, which was mostly iron clad wheels or iron shod horses, significantly quieter in sensitive areas, such as beside hospitals. I remember them ...

Re: Track Laying

Not making any recommendations, but in the very early days (45 years ago), with no local model shops, and unable to attend the big shows where traders were, I used cellulose thinners from Halfords to weld plasticard. It worked, if not as well as the butanone I use now. I think the point is that anyt...

Re: Track Laying

As stated, butanone dissolves some of the plastic. But it is important to keep some weight on it for a wee while (a few seconds for sassenachs) to force the softened plastic into the grain of the wood. With plastic sleepers you need just make sure the components are held firmly together until the so...

Back in the early 60's there was a bit of an epidemic of British drivers in France running off the road or into a tree, having apparently fallen asleep.

Re: Joggled Stockrails

I think it is true that joggles are relatively rarely, if atall, to be found on Scottish lines; perhaps this is true of some English lines also. The set is another matter, and is always necessary (unless your switch blades can taper to zero thickness). Certainly I have never used a joggle, and have ...

Re: early platform height?

There wasn't a standard, but many early platforms were much lower. This picture, taken about 1900, shows a station built in 1847. In this location, as in many others, the platform was raised later, but they couldn't raise the bit with the buildings on without unacceptable expense. There are still a ...

Possibly a slightly niaive question. The big pipe is to let water out to the various columns; but where is the (presumably smaller) pipe to let water in? There might have been a pump, possibly steam driven.

Very intrigued by your long 0.5mm drill. Evidently a long piece of steel rod; but how is the drill attached to it? Is that a collet on the end, or is there some other connection? It seems like the sort of thing I wouldn't need very often, but when I did need it I would need It badly. Allan F
