The tender is now largely finished, the only item to add are the buffers, but thsi will happen later as they will part of the re charging system for the batteries.

I have now started looking at the driving wheels for this loco. There are no S7 wheels available for it, in the past I would have bought some Alan Harris castings but these are no longer available. The S7 group do produce a 5 foot 3 inch 16 spoke wheel but this for a LMS 4f and the although it looks similar its not that close. The only other alternative is the slaters wheel for a stand 4 (76000 class) but these are finescale and need re profiling and thinning to meet S7 standards

You can see that the slaters wheel needs thinning by quite a bit, in this case by 0.65 mm.
I decided to do this by taking all the extra thickness off the back of the wheel
This is what I have done here.

There isn't a lot of flange left, so to get it back the wheel is going to end up a little smaller.
There is plenty of meat in the tyre to put the flange back, its much smaller in any case and this is what you get.

So now I have a correct thickness wheel but with a smaller tyre.
So this will be the way forward. The pony wheel and tender wheels are fine as the S7 group does produce those.
