    My last layout that I had til the early eighties, my father built in an absolute block system with relays so you had to set a path rather than just a signal and point setting as per a lever arrangement. He put in neutral sections energised by green signals and a correct path using cheap RS components relays and he had his mate on the S&T work out the electricals. One of the reasons Hornby/Triang lever switches are so shaped is you could with a bit of jiggery pokery mount them into the roof of a signal box thus give you an actual signal box control, sadly no bells but it had the curious and fun thing of a main train forcing a following train to halt at a red and proceed as the next but one block cleared. I seem to remember he set it up controlled using bus bars and each energised section was under control of one controller.
    For years I had all the paperwork and schematics from this but lost them in the mists of time, it was insanely complex but actually worked and I remember showing off my layout to school which prompted the creation of a rail club. He used I think momentary microswitches as signal treadles and seem to remember the logic work was the first movement of the train into a section would energise that section but kill the section behind which a relay on the next section gateway would release the first relay to be energised which powered up the signal and track circuit.
    Sadly as teenage years took hold and girls etc became more important than model rail, sold it for a very tidy sum prob a couple grands worth in todays money as it was beautifully done spending much time with papier mache, chicken wire, paints and model buildings etc to make it into a very detailed layout and no LED's back then all incandescant micro bulbs which was handy as BR NX panel bulbs my father got me a whole box of which ended up in coaches, engines, houses and stations. The thing produced a LOT of heat and smelt like a burnt out clutches cod piece but it was brilliance homebrew.

    Another well balanced and informative video. Watch out DCC Concepts et all! If 'their' products were a little more within financial reach for the average modeller - then maybe we would not consider this approach. I am impressed how you seem just to throw these bits of p/card together and form an operating point motor for less than a fiver (including servo). Thanks for the dimensions. Look forward to more of this kind of stuff in the future.

    Well done you. Thanks for the plug to my website. My only comment is that plastic mounts deteriorate with time especially if used in the loft of garage, whereas my aluminium mounts will last a life time. Also it would be very hard if mot impossible to change a servos should it fail in your mount. Regards Dave (Dingo Servo Mounts)

    Very cool build. Love how you’ve both visually and textually explained your method. Really like the simplicity. And, of course, the linear motion you’ve achieved. Definitely will check out your method for my point motors. Humbly think this method also allows for smoothly operating ‘remotely controlled’ points, turnouts and even is an excellent possible solution to mechanize scenes.
    Thanks 🙏 for sharing!!

    Good morning Nigel and Happy New year 🎉. You remind me of a model railway Allen Millyard 😉👍
    Glad I found your video on point motors as I'm about to start a new layout myself. I wonder there's a way to internally modify a small RC servo so that it doesn't need any external control just to give it a simple bi-directional sweep when the polarity of supply is reversed (the same as a tortoise)? I'll investigate this and report back. I did like your "tip of the hat" to certain work colleagues who I also know well 😂 I hope they supplied you with appropriate trainborne mince pies during the festive season along with the timings print off 🤔 😁👍

    Fantastic!
    I’ve also been experimenting with servo motors and have built prototypes from Aluminium Angle and from 2mm MDF. However they all have a point actuator arm that pivots and therefore rises and falls. Your solution which provides linear motion is a great improvement… with the added bonus of provision for micro switches rather than needing to use separate relays.
    To test the concept, I’ve built one of your designs (although I like to have the servo on its side) using 2mm card for the housing and 1.5mm card for the actuator assembly. I’ve not linked it to a point but it works really well.
    In the new year I’ll build one from 2mm MDF with the actuator assembly made from Plastikard.
    Thank you, and I like your assembly line production methods.

    Like these! They give a nice realistic throw to the switch blades.
    Typical point machines on the real thing will swing Normal to Reverse in circa 7.5 seconds, so this replicates the swing very well.
    Simple switch detection via the microswitch as well. Nothing wrong with simple! As an S&T man (now retired) I would be interested to see how you tie your point detection in to your signalling, but I guess that will a future subject? Nothing wrong with relay technology - the real thing has used it for well over a hundred years.
    Have you had any servo motor failures? I guess you would replace the entire motor module in the event of a fault, then bin the servo?
    Well-thought out concept!
    Spot-on! 👍🏻

    • @Wallsrail
      @Wallsrail  ปีที่แล้ว

      My self taught electronics is very basic. I understand micro switches and their electronic brothers, the relay. For the average model railroader, that should be enough!
      As stated in the video, the idea was copied from a Commercially available product. Having over a 100 points and signals, price became a large £actor.
      Many attempts were made to create something with simple repeatable construction. Some of the early ones have a Frankenstein look to them, still work though 😃
      Haven't encountered servo failure yet. And yes, replacing the whole unit would be the answer.
      I did design a crude interlocking system, for my needs, a few years ago. Based on 2 pole changeover switches with hundreds of diodes.
      It worked, but then I discovered the Mega Points system. Expensive, but does more than I could ever hope to achieve on my own.

      I need to take mine too 😝

    Hi, I was wondering if you had worked out the wiring for the limit switches yet? I want to run some Dwarf signals, one on each side of the track with 2 color, red & green, LEDs to show which track was open or closed. Can it be done with 1 switch for both lights or will I need to use 2 switches, one on each side of the bracket?
    Thanks, Pete

    • @Wallsrail
      @Wallsrail  2 ปีที่แล้ว +1

      No, not yet!! Getting around to it though!
      Should be able to do what you want off 1 micro switch. It is after all just a change over switch.
      I'm. gearing up to do a control panel video, which will cover how to do that. Not sure when it will be though, as got a backlog building up......

      But can be swapped for another size depending on what size of rod you want to operate the point?
      Third piece of front is used as a larger platform that the micro switch sits on. I sometimes use scrap/off cuts for this. Entirely optional?
