Ideally the motor shaft and sprocket would be slotted with one set screw to hold a key in place and a second to secure to the shaft. That is quite the mountain railroad, a miniature version of Cass Scenic. Great video, thanks much!
@@MillBrookRailroad It's never good practice to use the set screw as a drive component. A key or driven pin is usually used to transmit the force and a set screw is used to keep the key or pin in place. An alternative would be a splined shaft and sprocket with the motor shaft end drilled and tapped for a keeper bolt but then you're talking some big bucks. I learned long ago to become friends with people that have lathes, mills and key broaches. Fortunately, now I own that equipment.
Could you machine a woruff key and machine a keyway on the motor shaft and a square key way on the sprocket and use a setscrew...Bill has that beautiful CNC MILLING MACHINE 😊😅😂❤....ENJOY...OR A VISE BROCH GRIZZLY TOOLS HAS ALL THIS GOOD STUFF😢🎉😂❤
My philosophy on the drive sprocket: It is the equivalent of a 50-ton industrial switcher. The rest of the drive train can only handle 3000 pounds on the drawbar before components start to fail, so I'm trying to make the main drive sprocket the weakest point, but not have it fail during normal operations (pulling loads up to 2600-lbs. The traction motor sprocket is the cheapest and easiest thing to replace. My thought is that if I choose where the fail point is, I can make it easier to repair at night in the middle of the winter.
That is one heck of a hill.........I am amazed you have a camera lens left after all those tree smacks! LOL He needs some warning close clearance signs on that line! :)
That´s really mountain railroad. In that hot and muggy summer day, high altitude fresh and breezy air was sooo good that conductor sitting on caboose cupola with its head out fall asleep. Woke up was pretty harsh after head tree´s hitting twice. He´ll recover 😂😂 Can´t resist to that so super real fastly made logging line bridge. Your friend worked a lot, adding so much mileage in just a few months. That was a really good one you did Aaron !
It's a little running gag I have going through many of my videos, to have the camera fall or get hit by something. Sometimes, It's a genuine fall. sometimes, it's just for the sake of humour. The drive motor is perfectly suited for the size locomotive it is in. It is a 24V 500W motor inside the equivalent of a 50 ton industrial switcher.
Here’s something I learned about setting set screws , screw the screws down tight , then back off a quarter turn then retighten them , this seems to hold A lot better ..
Aaron is this the one you had a scary ride on? Man that’s a big hill there! Glad to see you fixed her up and rolling along! Stay safe in the RR!❤ video as always
The grades on this line have me wondering what you use for brakes! Does the motor have enough resistance to stop on its own, or is some other method used? If something gets away on this railroad, I’d give it 2 curves before it sails off down the mountain! With so many flat railroads out there, it’s neat to see someone push the limits of this scale a bit. Makes me wonder if anyone has tried building a cog railway in their backyard.
There are only regenerative brakes on my equipment. The Shady Pines own equipment is equipped with air brakes. There is a 7-1/4" gauge rack railway in England. ... but there are actually very few flat railways. The Mill Brook Railroad, for example, (a mere three miles from the Shady Pines) has a 3.5% ruling grade. The Brick Mountain Railroad has an 8% grade. The Shady Pines is probably the steepest at 10%.
Just a suggestion you may want to run some flat spots of the shaft of the motor that way your sets crew has something to sit in I'm going to make an addendum to this post you may want their if you have a Mill or grind a flat spot just remember to polish the shaft with some fine grit sandpaper to take all the burring off
That video had me checking for facial injury’s. And a derailment, I was jonesing… Jk Although a trust in that coupler….. Going down hill back first is quite trusting. Could go to exciting quite quick.
It sounds like the sprocket is making a periodic noise, similar to when my sprocket was not on the axle concentrically. Is there an issue with the sprocket alignment doing that?
how much battery life do you get out of it on a full charge? have you tested it until it starts to die? I know that probably would kill the batteries and I think you have 2 running in series.
It all depends how hard the locomotive works. If it is a fairly flat railroad and a fairly light load, then the batteries will last 8 to 10 hours. No matter what, they usually outlast me. I can't run for that long without a break.
That would compromise the strength of the axle. The sprockets are held to the axles with loctite retaining compound and are holding up quite well. The motor is the only place I use set screws due to the heat when working hard.
Very Surprised that a motor didn't have keyways already machined in the motor Shaft and sprocket 😅😮😢🎉😂❤❤❤.....very impressive RAILWAYS 😮😢🎉😂❤ Did Millbrook Shops use a electric golf cart motors??....Be cool to Solar charger to supplement the batteries longer......For late night Pellet unit Trains.....And Since Millbrook is Explainingtrack miles and helper service
There are flats on the motor shaft and two set screws on the main sprocket. The batteries are deep cycle marine batteries. ... and I am building a solar array to charge the batteries. I have a dozen 79W 12V panels.
@@MillBrookRailroad Are they of a size that would lend to being made into rail cars? I think it would be pretty neat to have a consist that would be able to recharge the locomotive, but I imagine there isn't much one or two panels would do if they were just strapped to a car. It would be awesome to see something like a Transformer boxcar that could contain a small array of panels that opened up so you could park in a sunny spot and charge while away from home.
That's not a railroad, that's a rollercoaster!! lol

The shaft does have flats on it. That's what the set screws are tightened on to.
The railroad is a good place to find the weak points on a locomotive.

You just have to take it for granted that you have to pull your knees in from time to time.

He built it in two weeks.
@@MillBrookRailroad oh oh you have a serious competitor ...
You inspired me to start posting my own railroad on Tiktok!
What’s your name in TikTok?
Another good video bro. Safe travels. Ken.
Liked the effect of nearly running into the trees. You have the same response as actually being there. That seems to be a small drive motor.

@@MillBrookRailroad Understand and appreciate your somewhat twisted sense of humor!
I think that loco will look great once you put all the transfers on it and put it into livery. Good job, well done....
Much better ratio of run by to POV. Keep up the good work.
I do like to mix it up. Sometimes, I have the time to get enough footage for a nice mix like this. Other times, not so much.
Thanks!
Thank you, Joanne!

This is the railroad I've had two runaways on this summer.

There are flat spots on the motor shaft from the factory.

Jk

Great shot, LOL.
"Weee... BANG!... huh?!?!"
may , need a helper locomotive on that railroad !... thats a pretty nice layout. its a bit like cass scenic lol
Cool!
Sharp curves and steep grades. That’s a real logging camp RR lol
The paradox is that he's right in the village.
It sounds like the sprocket is making a periodic noise, similar to when my sprocket was not on the axle concentrically. Is there an issue with the sprocket alignment doing that?
I'll have to look into it.
How far away is Shady Pines from Mill Brook?
About three miles.

Ever thought about drilling a hole all the way through the axle and running a extra long screw through it
That would compromise the strength of the axle. The sprockets are held to the axles with loctite retaining compound and are holding up quite well. The motor is the only place I use set screws due to the heat when working hard.

Need to fix that 10% grade down too 5%
It was more than 12% initially.
Instead of a set screw why not use a key way?
It costs more to broach a keyway.
@@MillBrookRailroad yes maybe so but there would be a lot less problems in the long run. No slipping set screws.
you're not supposed to beat on a motor with ball bearings Just thought you Would like know when the motor fails
I wondered how long it would take for someone to mention that. I usually burn the motor windings out before the bearings go.
@@MillBrookRailroadmaybe a bigger motor would survive longer ?
