Hi Tom A bit late to the party but a couple things. 1. Do you have a face plate? no need to use a chuck. 2. What ya’ll call “silver steel” us Yanks call drill rod will get stupid hard if heat treated properly, hence your turning issues. I don’t like using loctite instead of a good fit but you would have been better off loctiting the sleeve i instead of a shrink fit. We repair ammonia compressors and usually use 1018 or 1045 for sleeves.
I noticed that you heated the silver sleeves to red to expand them. I wonder if the rapid cooling in contact with axle caused the steel to harden. It might have been better to heat only to yellow/blue and put the wheel set in the fridge before fitting the sleeve. Shrinking was always going to be tricky at 1/2 inch diameter with such a small sleeve. As always, an excellent video.
Nice job and yes it's good to know when to stop before the real F'ing and Jeffing starts and the hammers start to fly. With those needle bearings would you think that grease be a lube of choice? Reason for asking my loco has needle bearings all round, and made the axle boxes to have wells for squeeze out of grease.
Thanks. I’m not sure, I think the key would be to keep it in there, but also, I think in this instance it was just too much load for the bearings to cope with, the weight of a driver on just two axles.
I will do an update soon, so much going on elsewhere, and with back recover I just haven’t really had time for the railway. It should progress soon I hope.
Would be interesting to watch the carb fix on the pit bike 👍

Great repair
Great fix
Happy birthday and one tank on the carrier 2 will look uneven in my honest opinion
Had a ride around behind your loco today when Alex was driving. Your trolley definitely wasn’t making any funny noises 🙂.
Thanks, it did seem a lot better.

Another good informative vlog Tom keep them coming! Is there any more news on your 5 inch garden track? Rgds Alan 🚂🚂

Any progress with the U class?
Have you been doing more on your home railroad yet? Are you going to post an update soon
I’ve not really been fit enough to do the groundwork, hopefully I’ll be back at it soon…
Stick with the steam please mate.
