Re: Double-sided tape recommendation

Thermal expansion with acrylic, ie perspex, is a real problem. If you look at perspex shop display cabinets for sandwiches, cakes and suchlike, you'll see that an awful lot of them are cracked where the perspex is screwed to metal hinges or the metal framework of the cabinet. The ones that aren't cr...

Re: J15 & G5 Wheels

My original post wasn't a plug for the society's latest publication. Honest. I recently persuaded my family members to buy me a London Road Models G5 for my birthday plus Gibson wheels for that and the Hornby J15, rather than something that I'd never use. Nigel is definitely right about the lack of ...

J15 & G5 Wheels

This might seem a dumb question but I'm flummoxed over which wheels to use when converting the Hornby J15 and the London Road Models G5 to P4. What sizes do I need and what are the merits of different makes. I seem to remember a year or more ago that for one of these locos (can't remember which) the...

Re: Semaphore Signal Control - The Bouncer

This thread seems to have been dead for more than five years but I touught I'd add my twopenn'th anyway. I have used an Arduino microcontroller and a stepper motor to generate signal bounce. I've written an eight page description in MERG Journal vol 48 issue No 4. I've made the source code for progr...

Re: A replacement for super glue?

My main reason for responding to this thread is to say that using this UV sensitive resin for small castings in RTV won't be a goer unless you can come up with a way of getting UV light inside the mould' unmless of course it's a one part mould where the resin is exposed. Two part polyurethane resin ...

Re: Rotating Ground Signals - colours of the lights

Thanks to everybody for all these replies, and so quickly too. It now seems that I will be able to have my ground signals illuminated during the daytime (or most of it) after all. The real challenge would be to have a sub miniature white LED inside the ground signal with three coloured lenses. I sup...

Re: Rotating Ground Signals - colours of the lights

Thanks Noel, Your suggestions for the purposes for the front, side and rear lights make sense. I will contact the GE Society for clarification, but my best guess would now be that the front light would be red to match the front face of the disc, or yellow to match a yellow disc if it can be passed a...

Rotating Ground Signals - colours of the lights

I'm going to incorporate rotating ground signals on my Saffron Walden layout. These will be the McKenzie and Holland GER type and as well as making them rotate I want them to display the correct colour lights which will be fed by fibre optic from a bulb or bulbs under the baseboard. However I can't ...

Re: Kites Croft

It's been over 18 months since anybody added to this topic so maybe nobody will ever see this, but I thought I'd add my two penn'th (if that's how ypou spell it). I found this topic while searching for Arduino and this is the only thing that came up. I have recently acquired the unfinished Saffron W...
