Repairing a Shifted Axle on our locomotive 

I really like your easy going and "it'll be alright" attitude. It seems nothing is a problem, just a challenge with a hidden solution. I do like your videos and I'm not a little bit envious of your layout. Greetings from Sweden 🇸🇪.

Love the Nonchalant throw away statements such as finger tight is right until it decides to remind you when it stops working. Lovely. Happy New Year from the UK.

Great job Aaron! Cory Mears

New here, but I'm having a blast with the hilarious conversations. Happy New Year.

Good video bro, 2 hours left of 2023 here in NZ so all the best over new years. Safe travels. Ken.

Thank you

Position to proper location on the Axle then remove Set Screw and insert a Center Punch or Drill Bit to mark the location on the Axle where the Set Screw needs to stay. Grind or drill a divot into the Axle to establish place for the end of the Set Screw to be "locked" in. Reinsert Set Screw and throughly tighten. If threaded area is deep enough insert a second Set Screw to act as a lock to prevent the one in contact with the Axle from backing out due to vibration. The Divot method or a flat spot filed or ground into an axle or shaft has been used by multiple industries to prevent gears and bearings from "walking" on shafts from where they should be aligned. Pillar Block Bearings usually use a Lock Collar with one or more Set Screw locations to retain shafts for that same reason. I hope that helps!

Kind of reminds me of working on A tesla, the more you work on it, the more it breaks

Hello thank you for your videos and your hard work at making them. Also.like you showing us se of the repairs you do to your engines a nd cars i hope happy new year to the family and yourself stay safe in 2024 ❤look forward to more videos

Your issue with the link is that the clip is directional and your chain moves in both directions, maybe a link that you peen over the end and make it a permanent link might be better.

I learned a nice trick about battery electrolyte you can taste small amounts without harm, if it tastes really sour it's acid no guess work, learned that in auto shop in college 52 years ago, sulfuric acid even if dilute will attack wood as well as most metals and if it makes contact with high sulfur content lubes H2S evolves.

Wow WITH your cnc Plywood Cutter Your railway could build a Alco RS-3......powered by a Solar power patriot Generator....Just what we were Thicking while watching it Love the RAILWAYS 😊😊😊😊😊😊

Aaron have you ever drilled a lock “ spot “for the allen screw that will secure the sprocket in place? if you have a pointed end on the allen screw, it will lock it on the shaft where it was drilled. just need a deep enough for a good secure point. still use loctite to secure due to all the vibrations and torque.

This might work - remove a set screw. Use a drill bit smaller than the diameter of the set screw. Drill a small indentation into the axle, through the set screw hole. Reinsert the set screw, seating it into the hole in the axle. This should help stop the wheels from slipping on the axle. Just an 'arm-chair' suggestion 🙂

Oh the work never ends will you ever get to play with your railroad 😁😁

Keyways on the axle

Get rid of the grub screws on the axles. You need either a pin or a screw pins. I have screw pins on the u-joints on my RC trucks and I have yet to break one. Granted the forces here are different, but its the same idea.

Another enjoyable video, thank you for sharing it. Ever tried gel cell batteries? Keep up the good work, & a Happy New Year to you & your family.

What about filing a small flat on the axle ends to facilitate tightening of the grub screws

Have you considered a ramp or lift to a comfortable working height, non of us are getting any younger!

Do these two critters MU?

So I guess the loctite never held them in place? The thing loosens up because the set screw doesn't have any spot to positively screw into (flat/keyed spot or a hole). It spins on there and thus the sprocket "walks" down the shaft one direction or the other. Once it slips, it burnishes/rubs down the screw/shaft and then it just keeps slipping more. Could explain why some years you have it happen recurringly. Another thing is, I have not seen your set screw up close, but some have a flat end and some have a pointed end. The pointed type might work better. The only concern is having too much stress in one spot, may cause the axle to crack under load, like on real trains. However, this depends on the type of steel and the overall stress, temperature, etc... stuff that's beyond my level of expertise.

You’re running your chains too tight. You can tell by the loud noise that they’re making. A chain should always be a little bit loose. A chain that is too tight will wear out the chain faster than it should. Plus it will wear out the sprockets as well.

Oh my gosh, you are so boring to watch. Yep, fell asleep.
