RMweb Gold Steve Hewitt Posted July 29, 2021 Author RMweb Gold Share Posted July 29, 2021 (edited) Another GWR Bracket Signal for Acton Wells ............. A little more compact than the cantilevered bracket, but broadly similar in design, this signal again has three dolls with a Stop arm on each which are stepped down from left to right. The two tallest dolls also have a fixed distant arm. My construction sequence has been a little different this time in as much as I have built and painted several major sub-assemblies prior to final assembly and installing the operating wires etc. The main structure uses a modified MSE bracket etch. Theere are sockets for each doll built in between the trimmers. You can also see the two cranks which will link the operating wires to the weight bars for the two dolls along the bracket. Each doll has been completed and is ready to install in its socket. In addition I have prepared the ladders which will give access to the upper arms of the two tallest dolls. Next steps will be installing the dolls and completing the optical fibre/LED assembly. Then its on with the operating wires...... Steve.

The arms are cleared in sequence: Hopefully the cranks I referred to previously are clear in this shot: And this one: The staging is stained wood: The servos and the LED are below ground: The overall height of the signal is some 130mm or 5 inches Video to follow shortly, I hope.............

RMweb Gold Popular Post Steve Hewitt Posted September 20, 2021 Author RMweb Gold Popular Post Share Posted September 20, 2021 (edited) A Little Experiment............. Having delivered the GWR signals on our way to Cornwall I had a discussion with the layout owner about future requirements. These will include a couple of signals with Route Indicators. I previously built a single post signal with a Route Indicator, but it only had two Routes. The future ones will require four Routes each! Refeshed from the holiday and waiting for some material deliveries I thought it would be useful to experiment with the MSE Route Indicator etch and try to squeeze four Flags into it. The Indicators will both be mounted on Gantry siganals, below and adjacent to the Doll and its Stop arm. This means the Pull Wires will come to the Indicators from the side rather than the rear as in the Post Mounted style. I think I've managed it: The assembly has been constructed to to establish the geometry of the various linkages. I hope the indicator can be positioned close enough to the leg of the gantry for the operating wires to be attached directly to the rocking levers. The levers could easily be replaced with longer ones if necessary. Alternatively, small cranks or pullies might be needed if the horizontal distance is too great. The second flag from the front is raised. That's all for now folks...... Steve.

RMweb Gold 5BarVT Posted September 21, 2021 RMweb Gold Share Posted September 21, 2021 Very nice, I wish you success. I assume that the relevant arm will be controlled separately and electrically linked (rather than use the balance rods to push it off). Paul. 3 Link to post Share on other sites More sharing options...
RMweb Gold Steve Hewitt Posted September 21, 2021 Author RMweb Gold Share Posted September 21, 2021 Yes indeed Paul. Pushing the arm OFF isn't the problem particularly. Its getting it to fall back to ON, as gravity doesn't scale very well. The arm will have its own servo, but the control system will ensure that the arm moves to OFF whenever any one Route is displayed.

Mike 84C Posted November 1, 2021 Share Posted November 1, 2021 Steve, a question. Is there any particular reason why you use the servo motor that you do? As there are others that appear similar which seem much cheaper. I ask as I'm building some signals for our club layout and this is virgin territory for me, one done three to go!

RMweb Gold Rowsley17D Posted November 1, 2021 RMweb Gold Share Posted November 1, 2021 In my experience there are servos and there are servos. I thought I could use really small, cheap ones that were on eBay for signals, big mistake. They were noisy and soon packed up. Like most things you gets wot you pays for. 2 1 Link to post Share on other sites More sharing options...
RMweb Gold Steve Hewitt Posted November 1, 2021 Author RMweb Gold Share Posted November 1, 2021 Hi Mic, I think Jonathan has answered you quite well. I'm not sure which servos you are refering to as I have used various models over the years. I currently favour the 3.7gram Digital versions, which I buy in bulk from China. The design is similar to the SG90 9g model which has been very popular for a few years. It is just a bit smaller. In the larger picture, the cost of a servo is a very small part of the total for a signal. Certainly not sufficient to compromise performance.

Mike 84C Posted November 1, 2021 Share Posted November 1, 2021 Jonathan and Steve thanks for such prompt replies and sound advice. I know which route I shall take. Steve I was in Accrington 6 weeks ago if I had known you live there I would have contacted you for advice. My grandparents lived in Ozzy and Clayton-le-Moors so a bit of a nostalgia trip for me. Drove over from the caravan club site in Bury. 1 1 Link to post Share on other sites More sharing options...

lyneux Posted December 17, 2021 Share Posted December 17, 2021 (edited) Hi Steve, I'm working on new signals for Oldshaw. I was looking at the fibre optic connection above. It looks different to the one you outlined on page 8 of this topic. Would you mind explaining how you do this or point me in the direction of a previous post (I couldn't find one when I searched) that explains it? EDIT: ignore my request. I think I found the answer a few pages back with your 3D printed connectors. Always difficult to navigate long threads on RMWeb!

ScRSG Posted January 23, 2022 Share Posted January 23, 2022 Steve, A question, if I may, how do you fit the completed signals to the layout? Is the signal(s) a complete unit including the servo units or are they separate? I find fitting the operating mechanism under the board and attaching the signal operating rods a difficult task so any "secrets" would help! Thanks, Chas Link to post Share on other sites More sharing options...
RMweb Gold Steve Hewitt Posted January 25, 2022 Author RMweb Gold Share Posted January 25, 2022 Hi Chas, The signals are seperate from the servos. The key is the foundation tube - usually 1/2inch dia brass. This locates the signal in the baseboard where it is retained by friction. The servos are mounted on a bespoke frame assembled from plywood. This is also located by the foundation tube. The operating wires for the signals are terminated in 1/16inch brass tube which fits in the servo horn. The final fixing of the 1/16th tube on the operating wire is done with the servo set to about mid-throw. (The Safe position on the GF Controllers I use). The signal arm is set to mid way between On and Off and tube joint soldered. The servo is then adjusted via the Controller to the correct ON and OFF positions. Unclipping the 1/16th tube from the horn allows the signal to be pushed up by its Foundation tube for removal. The relationship between the signal baseplate and the servo frame is critical. This is the thickness of the baseboard. I assemble the signal on a frame - the Transport and Test Frame - which represents the baseboard thickness as accurately as possible. The signal will be delivered on its Transport and Test Frame where it can be connected up to its servo control and tested. I hope all this explains the signal installation process adequately? Regards, Steve. 3 1 5 Link to post Share on other sites More sharing options...
RMweb Gold Popular Post Steve Hewitt Posted February 13, 2022 Author RMweb Gold Popular Post Share Posted February 13, 2022 Another GWR signal for Acton Wells........... During the last few months, I have constructed several signals for the fictitious Acton Wells. I apologise for not detailing the construction previously, but the latest is a little out of the ordinary. I hope this video is self explanatory, but if you want any further details just respond on this topic. Steve. 9 17 Link to post Share on other sites More sharing options...

Michael Hodgson Posted February 14, 2022 Share Posted February 14, 2022 Excellent workmanship, congratulations. If you have the skills to do that (and I know I haven't) the ground discs should not be any more of a problem to do. Maybe more difficult to get two more servos close to those five though. I think I would be right in saying the way the locking usually worked would mean that indicators operated slightly before rather than simultaneously with the arm?

Shouldn’t do, as the mechanism is similar to a lower distant slot (OR rather than AND, but they didn’t do Boolean logic back then!). Unless it had been fitted with a lot of slack in it, but you wouldn’t want that as it would make it more difficult to get the arm off properly.
