Re: Brimsdown-The last grand project.

Hello Tony Thanks for your very comprehensive reply, electronics apart, It was clear and I fully understood it ( slightly to my surprise). I do sometimes find it quite surprising just how many different approaches there are to model train control and yours, Doug’s and Terry’s approaches illustrate i...

Re: Brimsdown-The last grand project.

Hello Tony
Impressive planning and wiring as I would expect from you! What do the relay cards do? I’m sorry if it’s very obvious and / or you’ve already gone into great detail about it and if that’s the case tell me and I’ll go hunting....
Kind regards

Re: Brimsdown-The last grand project.

Hello Tony Well you don't hang around do you. Thanks for the explanation of why I twisted the wires together. Rather unintelligently I just read about it on the Merg site (Davy Dicks treatise on layout wiring) and carried out his ideas without really understanding why! So now I'm a further forward i...

Re: Brimsdown-The last grand project.

Hello Tony A clear explanation of wiring requirements for both DC and DCC. I could have done with this a few months back when I was installing the main traction current feeds for Yeovil. I ended up using 32/02 just to be on the safe side and in fact twisted them together which I’m reliably informed ...

Re: Brimsdown-The last grand project.

Re: Turntable troubles

Hello everyone Firstly I'd like to thank you all for your experiences and ideas. I think if I knew when I started out trying to motorise a turntable what I do now, I'd probably have gone for something much simpler or maybe the stepper motor route. The Chatham mechanism however is not without its goo...

Andrew, I have been struggling with the same drive (https://highlandmiscellany.com/tag/turntable/) and although there are a number of aspects I like about it, there are some fundamental flaws too. Chief of these is that the arrangement of the locking plunger (what is refered to as a detent above) i...

Does it behave the same way in both turning directions? Hello John No it doesn't.

If it's the mechanism in this video: then I can see a problem. Look at the detent assembly down at the bottom: it's flexing and rattling all over the place!

Re: Turntable troubles

I tinkered with mechanical locks but found it too much faff. I abandoned the gear mechanism for toothed belts and thus needed ...
