It's really nice, but two things. One, it looks expensive, and or time consuming. We have adapted to servo control because it is "cheap". Two, when you have scores, or in some cases hundreds of turnouts, you have a ton of wires running through your layout. One way I mitigate that is using controller boards like the "Jack Wabbit", DigiTrax DS74, etc, that are addressed from the track bus. Still, it is a mitigation and not solution. Ideally, we can come up with turnouts that tie directly into the track bus, without any mediators. A servo with it's own "mini" decoder, that would tie directly to the local bus would be perfect. It would save the wire bulk that clutters up modern layouts, as well as add to their complexity.

What you've done is similar to how I operate my point work, but yours is much neater. I use a C&L mechanism to operate the point blades and this is connected to to the servo mounted on a MERG servo mount by a adjustable brass rod {adjustable turnbuckle}. Two brass tubes go from the C&L unit to just underneath the point. The tie bar attached to the point blades is from a Masokit etch which folds up into a fairly realistic looking tie bar. I then have two more brass brass tubes that are soldered to the tie bar that are just shy of the tubes from the C&L unit. Two long brass pins pass through the tubes from the tie bars into the tubes attached to the C&L unit. The whole set up is screwed to a piece of wood which is then screwed to the underneath of the baseboard. Your design is much more compact. I wish your ones were available when I was doing my layout. LOL. I use Megapoints to control the point work and signals via a lever frame.

Hi James, DCC Train automation already sell these. MTB MP1,5,6 and now I think they have a new MP10 out. They have the eccentric to effect a linear reciprocating motion but you could add your brass bar and twin prong set up (which is much more elegant than the single pin through the tie bar hole). They have switches built into them too for frog and signal switching. David.

Very interesting approach! And easily adjustable, since you have your own 3D printer. On a somewhat related note, I remember watching a video by rcgrabbag, with some home-made turnouts on a bridge, for which he had to route the actuators far away from their location - maybe it could be of interest to you, too.

Very cool mechanism James. The bar in brass will of course pose a difficulty on what material you’re going to use as the rods between bar and blades. Can imagine that would also be best in brass. However, then you’ll bridge the rails into a short. Can imagine two brass tubes over a rod and a plastic flange in the middle, in the same diameter as the tube, would do the trick. Can also mean your parts can be made adjustable for different gauges. And the two pieces of brass tubes can then be identical, which would make production more easy and cheaper. Also am curious to what kind of visual throw bar you will come up with between the sleepers. Can imagine the path of travel could become even smoother when a kind of throw bar is added. Not to say, that such a throw bar would further enhance the realism of the model turnout. Last but not least, for complicated turnout placement; this kind of mechanism would really improve turnout functioning over longer distances also.

Hi James, You've set yourself an incredible amount of work! If this doesn't work out for you I would try a purely mechanical arrangement based on prototypical operation at the time! Thanks for uploading.

Thats a very good idea and workable. Might be a problem with its length should you have Two points side by side. Another handy addition might be to add a raised section on the operating bar to operate one or two micro switches for frog polarity etc. I know you like to do your own thing having watched you from the beginning but there is something on a similar basis made by Dingo Servo Mounts. A system I have used and is extremely effective.

Great idea, but have you considered that you will need microswitches for both the frog polarity and the interlocking on the Arduino. EG. the Arduino will need to know in which direction the points are set at power on and for signalling. You haven't included anywhere to mount them. Probably, at the far end of the push bar would be the best place, although horizontal pins on the push bar could be used to operate the microswitches.

Very Nice solution, if the printed slide bar proves to be unsuitable, I'd use a nylon bar, with syringe tubes for the risers. The point blades each having a piano wire attached to the blade, the wire then being threaded into the syringe tubes. This would retain electrical isolation between the blades, and easy removal / refitting of the point motor assembly. The wires could protrude below the base board, the tubes extending to almost touching blade. Hope that makes sense.

Hi James, That's an interesting solution to be able to move the points. I wish there was something like that available for when I made mine which I ended up using the copperclad method.

Btw If you make that whole bar brass then you will just create a short when it's connected to the rails? Cheers, Michael

I've always found turnout actuation to be one of the biggest grey areas - so many people have so many opinions when it comes to how to handle it with hand laid track, and almost none of them are novice friendly, frequently referring to old hardware, discontinued products, etc. - this looks wonderful. Is the idea to solder the actuating pins to the bottom of the blades and then drop them through the holes in the operating bar? Or maybe the operating bar has small ID tube that the soldered droppers slot into? I'm half and half whether to go with mechanical or electrical point switching, but it looks like the same mechanism would work fine with wire-in-tube or crank rods also. I personally would buy six or even of these assuming the TOU-to-blades config is settled?

Firstly, I have not made any point motors at all, so just uniformed observations. The horizonal motion will require a slot in your baseboard rather than a single hole. Concealing a slot may be more difficult than a hole. As you are going to A LOT of effort to get Bexhill to look right are you going to be happy with the result. If there is a likelihood of the pin between the bar & the sheaf falling out you could try an old Russian tank trick of having a ramp that knocks the pin back in every time it moves. Inside the Chieftain's Hatch: T-34-85, Episode 1 Shows this, about 5 minutes in. These things aside, that’s a nice design of mechanism you’ve got there; would you put them in your store?

Hi James, a neat solution , as always, could also be used to animate sliding doors and it strikes me that with a little modification (dual cams on one servo) could actually be attached to a pair of sliding doors, my one area of concern is the pins you are going to use to link to the tie bar, they are going to I suspect be quite fine so the question is will you mount the unit directly to the underside of the turnout or below the baseboard ? If it's under the baseboard use some wire with a bit of spring in it maybe ? Then a tiny amount of over travel at each end will get the spring of the wire to hold the blade tight against the side rail on each side

Hi James, For some time I’ve been wondering whether it would be possible to control turnouts/points using servos attached directly to the underside of the sleepers. Your solution using a sliding bar is ingenious, but your prototype looks rather large. Though I haven’t developed the idea, I thought it might be possible to use a gear fitted to the servo to drive a toothed bar attached to the points switching blades. While this would keep the entire mechanism small, it would require a relatively large hole in the baseboard - relative to the conventional approach, that is. In my case, I’m using an insulation material (Kingspan) under the track, so a larger hole than normal would not be a problem. Of course, to allow for ballasting, the underside of the sleepers would need something to prevent the ballast disappearing through the hole - even paper glued to the sleepers would do. I would be interested to hear your thoughts on this potential solution. Stay safe. Stephen

Hi Stephen, the sliding bar idea is great although not mine. It seems to be common practice among P4 modellers. The aspect of this is the eccentric to control it, I've not seen it done before.

It takes the concept to the next level which I think will interest some people. Best wishes, James

There's always something ridiculously satisfying about watching an eccentric thingie rotating. But I'm not sure how you're going to connect it to what I've always thought was the tie bar, but which I think is properly called the stretcher bar, to transfer the movement to the point blades. Are you taking two rods up vertically through slots in the baseboard to connect to (or to be) the tie/stretcher bar? Would the parts of the eccentric movement not be better cast/etched in metal than plastic? Would add massively to the cost though, I'd guess.

Yes, two pins on the side "camouflaged" as the connection from the rod to the blades. Not T-bar. The piano wire acts as a spring pressing the blades onto the outer rails, too. Servo + semaphore signal + Andrino -> look into semaphore bouncing 😉 ~16:30 You already know that I am against radio control. - BUT - Yes, the turnouts and signals independent from locomotives (feed by the rails) for federal control, for when layouts join modular up to one very big layout (that would be season 3 or even 4 - I guess). ~17:10 depends on the search words; "H0fine Weichenantrieb" for example brings some results, as well as ship and plane modellers often got similar solutions as they usually go the servo way.
