Tender Repairs

[shoey51]

I thought I had fixed all the problems with my 7.25 gauge loco but a couple of weeks back while on a run it felt as tho i was driving with the breaks on. After I got home I turned the tender over to check things out and found that the axle boxes wer badly worn



will have to think about how I am going to repair these

after talking with some knowledgeable friends I have now mounted the axle between a couple of centres and using a lathedog to turn the axle Im about to embark on some repairs.



this photo shows how worn the tread is so thats another job too



any suggestions gratefully received as Im still learning here

cheers Graham

You could skim down the axles make new axle boxes and fit roller bearings.

As for the wheels you can skim off the wear and fit steel tiers:- making them a tight fit and squeeze them on with high strength loctite.

I found a place that had castings and managed to get the casting for the axle box
I took it to work and cut it into quarters. tried to square them off in the mill but i think i need something better than a large slot dill to do the job

By `ek Graham! That`s some wear! 

What sort of load does it usually carry? 

Looks as though your on the right track for efficient, lasting repairs.

David the only weight was the water about 10ltr and coal about 2kilo and driver. the original owner wasnt a big man. there wasnt any oil holes or reasing points so I assume it has been running dry for years.
Ive also bought some bronze bearing bushes and grease nipples this time Im going to keep it lubricated.

I bought a fly cutter for my x2 mill yesterday so heres to another new experience

here's an update on whats been happening in between holidays overseas and all

after machining the boxes to size which i ended up doing on the lathe I drilled and bored out to press fit some bronze bearing bushes


I also drilled right through with a 13/64th drill so I could tap 6mm for a grease nipple. used a slot drill in the mill to give a flat surface to screw it up to



marked out where I had to slot for the guides


then milled them out


here is a phto of the finnished wheel set after turning down the wheels as well



not long now before it's back on the rails

Nice work Graham! 

It will be good to be rolling again..... Up high, on an even keel!
