Check out John JMC's channel at kzread.info and his Halland exhibition layout at facebook.com/Hallandlayout 👍

Warning! I've used this exact method, the first time it worked _perfectly_, the second time (U channel also from Wikes) the servos fell out - the 15.5mm is the external dimension, the thickness of the channel section is not part of the measurement and apparently can vary a bit batch by batch. you can deal with this by putting some sellotape round the servo to thicken it a little, doesn't need much but be aware it may not fit securely first time. it works very well once you get it though another trick though, useful when you have two points toe to toe, have the toe end mounting screw a bit further back so its under the servo once installed, uses less channel as well in the end I moved to home made 3d print servo mounts (on thingiverse if anyone cares), but the channel method is perfect for those without. note also the channel can be drilled and tapped on the sides to mount microswitches as well and operated by the side bits of the cross shaped horn (you need to cut off the end of the horn that goes inside) that said, having watched your earlier video on using servos convinced me totally, 100% behind using these, the are quiet, nice slow action and amazingly cheap thumbs up all round

Hi Rob, what a great solution. Seams to simple to work, a little time and care and the mounts should be great and good to go. Thankyou for this solution. Best Marc

Hi Rob, great "tutorial"! Just a note for readers following this advise. At 3:16 on the clip, you advise drilling a 3.5mm hole approx. 5mm further in from the 1.5mm hole. This is bad guidance because if the 3.5mm hole is centered over the 10mm hole in the baseboard, the 1.5mm fixing hole will be on the edge of the 10mm hole and will not provide a good anchorage point. This advise would be fine if you clarify that the edge of the 3.5mm hols and 1.5mm hole should be 5mm apart. I would advise that the centers of the 1.5mm and 3.5mm hole should be at an absolute minimum 8mm apart and suggest 10mm as a comfortable distance.

Great video Rob. I saw a similar idea on the megapoint controllers site (by Dave Fenton. He coupled his with switches for point indication and frog switching which was neat) Works really well but working under a baseboard to fit was challenging but not impossible. Thanks for sharing (I have voted for you re best channel) Keep them coming please!

Thanks Stig55! I think John JMC also uses MegaPoints controllers.

Your video describes exactly what I do. I scratch build my turnouts, and I power the frog with a micro-switch which I control with another wire connected to the servo. I use CA cement to fasten the micro-switch to the aluminium. I do glue the servos into the channel with CA.

Good to know this is a tried and tested technique on other layouts. Scratch built turnouts sound impressive!

Great method looks like it can be used in other prototyping applications using servos.

A super tip Rob, thanks for sharing it with us.

I have done something similar, except I mount the servo vertical. On each side of the servo, I mount a micro switch. When the servo rotates, it activates one micro switch and deactivates the other. Be sure to use micro switches with NO/NC connections. These then can be used to power the frog and indicator lights, just like a tortoise switch machine.

Any chance of seeing how you attached the micro switches and where you got them from?

Hi Rob great video as usual, I use a couple of different 3d Printed mounts depending on the use ie. signal head or point, above or below base board. I find 3d printing the most flexible way of mounting servos as you can modify depending on need.

looks too simple to work. But what a great idea. Are the 3d printed mounts available anywhere but MERG? I have not joined yet and still need to buy their block detectors... once i know what I'm doing...lol

Great info. Do you know of a source for servo mounts that include a mount for a micro switch? Thanks again for the valuable video.

Hi, I check the servo link you add to amazon for buying, the quality seems not to be a hit? Many buyers seems to text servos not working after some time…

How did you center the servo

You forgot to centre punch the position of the holes.

Laurie, I don't even know what that means, that's how bad I am at this stuff! 😬

I've looked around for the servos and it seems to me that the metal-geared ones are called MG90, instead of SG90.

@LittleWicketRailway

Жыл бұрын

It's a bit confusing. Some SG90s have a metal spur gear, but the other gears are plastic. MG90s are all metal gears, but are about twice as expensive. I've never used an MG90, so I'm not sure if they are the same dimensions as the SG90.
