I have been developing my own 3D printed working semaphore signals and now have an LMS round post upper quadrant. The unit fits and is secured from underneath the baseboard, through a suitably drilled hole. This can then be filled in leaving a relatively small base compared to the Dapol ones. The video shows one set up to a signal "bounce" controller for better effect. For a fuller explanation, please see video link below.

I know that @DarrwestLU6 was asking about this LMS signal so the link is below.

Being self critical, post printing of the signal arm, I forgot to clean up the danger lens hole so the RED light is not as obvious as the CLEAR light. That will be rectified for future.
Any other comments are more than welcome.
Dennis.

Excellent! :claphappy:

Are you sure there's not a little guy under the baseboard hauling chains to operate it, though? ;)

I have just received 6 GWR home signals from Delboy and am very impressed with the quality and value. They were tailor made to accommodate my baseboard thickness and they come fully assembled with operation by servo via a servo tester (supplied) also with full detailed instructions, which are needed to dismantle in order to paint the arm and column and to locate and wire up. Otherwise they are ready to plant. A PM to Delboy will no doubt get you a quote etc if you are interested in getting some working semaphores.

I was wondering how I missed all this wonderful stuff, but then looking at the dates, I realised that I was laid up in hospital, but that's no excuse, I managed to keep up with other topics at the time.

Anyway, now that I have, let me say well done Mr Delboy, most impressive indeed.

Triple  :thumbsup:

Excellent work.

Very good work. Having done it myself I know making working signals in N is quite an achievement. Well worth the effort though.

Thanks for your kind comments gents.
The link to the video below shows the GWR signal and controller (which can be placed as shown on the video in a signal panel) and using the travel limiter, seated underneath the potentiometer knob, the signal arm is restricted to travel between the CLEAR and DANGER positions to align with the built in LED for night time use. That signal post equates to 25 scale feet. The speed of movement of the signal is in the control of the operator. alternatively the, controller can be discarded and the signal used on other well known servo controllers available on the market.

After much toiling in the garden and odd jobbing around the house, I finally got around to attempting to improve my working semaphore signals and this time specifically the round post upper quadrant signals.
It was difficult to disguise the fact that I was feeding LED wires down the outside of the 3D printed round post signals whereas with the square post GWR signals I could hide them in a groove.
I thought about 3D printed round tube but the outer diameter of the posts would have equated to at least 12" (in excess of 300mm) which in my opinion was excessive. Also the finish was not that great, so I decided to pursue brass tubing with 3D printed upper and lower pivot blocks. The assembly is primed and sprayed and I feel gives a much better effect.
The Youtube video below shows it working with a simple servo potentiometer set-up, using a signal arm limiter to ensure there is no over-run of the arm and hence guaranteed alignment with the LED for DANGER and CLEAR. When I did the video, there was no access ladder on it but I have since added one as the photo below shows.
Please feel free to comment.

Very slick! Both the signal and the video. :thumbsup: :thumbsup:
