Re: McKenzie & Holland Ground Signals

Andrew, are you aware of the drawing in WRA vol. V no.5 [May 2012] page 114? Noel Noel, How could I have forgotten this? (Now that's a question that I trust will not elicit a sensible response!) The drawing indeed shows the rather clever "crank" that makes the lamp rotate and also appears...

McKenzie & Holland Ground Signals

Following advice on this Forum about the use of servos for signal control, I started work on a set of 4 ground signals. I had cobbled together the first one when Mark Tatlow published information on his superb signal models including a rotating McKenzie & Holland ground disc (putting my efforts ...

Re: A Highland Miscellany

At point B on the main drive but a little way down where it moves out to match the throw of the servo horn, I have introduced a link to a crank (C). This is prevented from slipping up and down the throw of the main drive by a couple of washers (10BA nuts soldered in place in this case). Thus as the...

Re: First dabble in P4

Personally I'd use a resistance soldering unit for this sort of item. The biggest problem with tiny objects, like lamp irons, is often the lack of positive location to hold them in place while soldering. Next time, have a think about drilling and pinning - epoxy, or even super glue, will then work f...

I've not used the technique on track work, but I have with wagons - well worth the effort of learning how to do it.

Re: Missenden Railway Modellers - Spring Weekend

Take a problem to the weekend (something that doesn't work, or something that you do not know how to do) and it's odds on that you will leave with the problem solved. And you'll probably learn a few things you hadn't thought about before you went as well. Do take ...

Re: Aluminium angle for cassettes - warnings!

Thanks to you all for the interesting, useful and fun discussion. I've certainly learned some things to apply when I construct the next cassettes.

Aluminium angle for cassettes - warnings!

Re: Power supply

Do you need to know whether power is available or whether current is actually flowing? The first is relatively easy with a light but the second would be more difficult. The sophisticated solution would be a couple of proper meters... You could try giving RS Components a call - its many years since l...

It worked! Another underframe has now been made with plastic solebars and glued together with gel superglue –...
