Re: Modern Era Concrete Track

...when the gauge was reduced from 1435 to 1432 (Misguidedly somtime in the mid 60s) ... I remember finding in the early sixties information in a London Underground publication that their lines were to 4’8 3/8” gauge. Am I remembering this correctly? How many P4 layouts should have been laid to 18....

Hi All. ... The only thing I'm not quite sure about, would they have a leaver to operate or co-act with the cabin? Everything else {except the crossing gates] were operated via the Box.

Unfortunately smallest metal headed pins are, I think, 0.4mm.

Re: fine (entomological or insect) pins

Thanks to all for the interesting and useful suggestions. Wire or headless pins can indeed be used in many circumstances, it's just that a pin is often easier to use: - there's a point making it easier than plain wire to insert into a hole - the point makes it easier to push a pin through things (pl...

fine (entomological or insect) pins

Many decades ago I bought some entomological pins and I've now run out of one size. I've tried UK specialist suppliers and searched Amazon and Ebay without success, one specialist also checked with their suppliers and could also not find any. What I'm after is what was sold as No. 20 pins that are v...

Re: Signalling for Tingley Common

It's outside my own particular area of interest, but is the layout typical for the GNR? It appears to be a small station so is the (running) loop for the goods yard normal? Instead of the 2 crossovers at the left hand end I would have expected a trailing connection from the lower main line with a si...

laser welding

I’ve just seen on BBC’s “Repair Shop” a laser welder being used by a jeweller - looks just the job for fine “soldering” work. Only problem could be the cost... but laser cutters have reduced in price a great deal so there may be hope. Has any one had experience with this technique?

Re: problems making wagon brakes

Guy, Thanks for the suggestions that I’ll study carefully. I think your approach to 3D printed brake gear is great for working layouts, but may be a bit limiting for “glass case” models. By the way, I can’t remember if you put the information in one of your posts, but how much clearance do you plan ...

Thanks for the encouragement. David, I have the tools but these days I doubt whether or not I have the dexterity needed - I’ll have a go. Nigel, at first glance a minimum thickness of 0.5mm seems to much for most bits of the brake gear but I might give it a try. I have another project involving unus...

problems making wagon brakes

At present I'm slowly making a model of a Rhymney Railway brake van and I've hit problems with the brake gear. Unfortunately there's no commercial product that I'm aware of that is a close match so it will have to be scratch building. (For a one off I think the costs of designing and etching one set...

I'd look at using Masokit's early PO wagon brakes - the push rods can be shortened easily. I believe I used them when converting the Bargoed wagon to P4 a few years ago - unfortunately the plastic in the Blaenavon wagon had degraded over the years and it broke up while I was trying to convert it.
