104 - Shelfington - Preparing Servo Motors
Рет қаралды 943
Күн бұрынWelcome to Ian's N Gauge channel!
In previous videos I’ve shown why I'd made the decision to use micro servo motors to control point movement on Shelfington.
In this video I thought I'd show how I'm preparing the servo motors, so that they fit snugly inside my servo enclosure boxes.
Thanks very much for watching.
Ian

Morning Ian 🙂 That's a neat solution and method, and I'm pleased to see your fingers survived unharmed (at least in what you've shown)! This morning I watched the latest from NScaler64, who by coincidence also shows use of a dremel - he has what look like heavy-duty protective gloves, so if you're worried about the fingers then that might be a way to go.
@iansngauge 2 ай бұрын
Good morning Jonathan! Haha! Yes, I still have all of my fingers! I'm not caught up with NScaler64 yet, but don't think I'd be able to wear gloves, just because it's quite delicate work, and being able to manipulate the servo easily would be hampered by wearing them! All the best, Ian.

It's amazing how a bit of time / pondering brings the solution. The Dremill and a small file was used throughout my track laying, i always thought it to be a superior method to the Xuron cutters that seem to crush the track a little. Very enjoyable Ian, enjoying your journey.
@iansngauge 2 ай бұрын
Thanks Chris! Yes, as you know I like to experiment, and hopefully they're worth watching! I've not actually tried cutting track yet! I've had good results with the Xuron cutters, but was thinking about using the Dremel to add gaps in the track when I need them for block detection - instead of using insulated rail joiners! What disc do you use in the Dremel for cutting track? Cheers, Ian.

Great work Ian, the boxes are very neat, I've used 3d printed enclosures for servos before which I screw to a square of plywood which I then embed into foam and glue in place.
@iansngauge 2 ай бұрын
Thanks Andy! Having a Cricut machine has helped cut out my enclosure box parts, and saved a tremendous amount of time, otherwise I'd have probably invested in a 3D printer and done similar to yourself! Cheers, Ian.

Awesome progress Ian. A couple of years back I bought a diamond cutting disc for my Dremel, which has worked wonders and appears to have a better live span compared to the normal cutting discs. (It is also a bit thinner as well) As for mounting the servos, I'm planning on mounting them below the base boards, directly under the points. I'll be using a self designed servo holder to which I'll also mount 2 micro switches. 1 for the frog polarity and the other for position feedback. As for the points themselves, I'll be removing the springs to allow for realistic point movements.
@iansngauge 2 ай бұрын
Thank you! I'll have to check out the diamond cutting discs, especially for cutting the rails when the time comes! Unfortunately I can't mount the servos below the baseboard, as the thickness of the foam causes a problem with throwing the points because of the length of the actuator bar required! I'm not sure what controller I'll be using yet for operating the points, but don't think I'll be using micro switches! Not sure I'll be removing the springs either, but we'll see! All the best, Ian.

Looks like you could do with a small hobby vice, the sort you clamp on to a workbench or baseboard, then method 2 can be applied but with a junior hacksaw. Its what I do and it does give a close, neat finish and its more "finger kind"!

Hi Nick! That's what I thought! I purchased a small vice a while ago, but it won't clamp to my makeshift workbench (dining room table) properly! Cheers, Ian.

I use the same motors, I started out by jamming them into 15mm U channel screwed to the board, this worked, more or less. now I use (after being unable to get more U channel that worked, the dimensions inside having changed slightly) a 3d print housing. this screws to the bottom of the board so its actuator hole is under the point lever hole. the servo is a "clip in" to the housing. this works, it takes up more space than your method though. have a future layout where if it happens what you have is planned for the two layer fiddle yard, the upper deck at least to save height. awkward bit is adding switches to them, in the end for layout feedback I went with the controller knowing what they were set to and left it at that, after all knowing the servo position doesn't tell if if the rails actually moved anyway - for and physical electrical switching the control board (an arduino with a PWM servo driver added) can switch relays if it has to
@iansngauge 2 ай бұрын
Hi Dale! Yes, I've seen many people use the U channel method of securing them, and would probably have done that myself if I was securing them directly to the baseboard! I've also thought about using 3D printed housings like yourself, but spent the money I'd reserved for the 3D printer on a Cricut machine instead, which I think will be more useful in the long run - although I haven't ruled out eventually getting a 3D printer! Lol! I've not completely decided how I'm going to control the servos yet, but do doubt I'll make videos of my decision making process!!! All the best, Ian.

@@iansngauge best way to control comes down to what you are comfortable with that works. if you want to control over DCC there are a few options. the best bit with servos (if you have removed the spring) is slow action is possible, if not then it hardly matters. one arduino can control plenty and be made into a DCC decoder. plenty of commercial solutions as well, all work, worth a play about and yes those Cricut machines look amazing
@iansngauge 2 ай бұрын
@@aleopardstail - I'm definitely going down the DCC route, and have a Megapoints controller and a Digikeijs servo controller to play with! I've also got an Arduino I still need to take a proper look at, and will probably end up going down that route in the longer term! I actually quite like the affirming click noise that the points make when they're thrown, so will probably leave the springs in the points! Cheers, Ian.

Hi Ian nice work on yhe servo boxes, I'm not having servo on the new layout unless you get good quality one's the can be a bit hit and miss, when i did use them i did take the spring out of the point for a smoother transition. The new motor I'm using are similar to a servo, just hoping they last longer. Colin
@iansngauge 2 ай бұрын
Thanks Colin! I'm really pleased with how the enclosure boxes have turned out! I'm probably going to leave the spring in the points though, as I quite like the affirming "click" telling me that the point has actually changed! Which motors are you going for this time around? Cheers, Ian.
