Hi Rob, Thanks for that. I was manufacturing the 85A pointwork kits and components between 1974 and 1984. Those ones are looking a bit scruffy after 40 years. The description is in error in saying the copper-clad was etched. It was actually milled away to leave raised bevelled pads, representing the base of the chairs and raising the rails above the timber surface by the correct scale amount. The solder fillets then represented the chair jaws. When painted the result was a good representation of chaired track for its time, before the introduction of injection-moulded chairs. The switch rails were machined to the prototype planing, and rails supplied with all pre-formed bends. The vees were silver-soldered and finished, ready to be soft-soldered in place without risk of coming apart. The tie bars (stretcher rods) were unclad fibreglass in a pivoted design to eliminate all stress on the fixings, like this: 2_060951_320000000.png The description also errs in describing the kits as Right Hand. The one which has been started is now, but the kits as supplied could be constructed as either hand. Templates for both were included. The diverging stock rail was overlong with a set in both ends, with instructions to cut off the unwanted end. The remaining parts were interchangeable for either hand. cheers, Martin. |

Hi Martin, Sounds like you took the trouble to make the kits as easy as possible to put together The turned pins on the tie bar are a good idea - I assume the pin is allowed to rotate in the tie bar so no stress is created as the switch rails move. I have been using NS wire soldered to the blades and located in holes in the tie bar. I remember a lot of people just soldered the switch rails directly to a copper clad tie bar - not so good Rob |

I use small brass nails - forget what they're called - shoved through from underneath the tie bar (countersunk so they don't project below the bar), bent over then soldered to the rail. Same idea. Nowhere near as neat! Nigel |
