The idea of building a Jenny Lind was put into my head by Williams the Steam well, that and the fact that the original was first built for the LBSCR. I think that I may have made a rod for my own back though as the driving wheel is fitted to an inside frame arrangement that is fixed to the smokebox at one end and the firebox at the other. Mixing sheet metal work and engineering to me seems an odd thing and if I went down that route, I think that the driving wheel arrangement wouldn't work that well if at all. I've been trying to think of another way of mounting them but haven't come up with anything as yet. The title of 'Jennifer Who ?' is because, like Enigma, I shall only be basing this model on the prototype. My capabilities won't run to producing a true model. Just look at that pump which is bolted to the firebox. That in itself would be a very tricky thing to make and very time consuming as well.
The photos show the wheels machined up and the axlebox guides formed. I'm not happy with the way that the driving wheels came out and so, I'll be machining a new set, when they arrive. One other thing that looks very odd is having a 5/32" hole for the driving axle. One reason for this is because the gearbox has a 1/4" hole for the axle to pass through. So that there is a decent shoulder for the wheel to bear against, the axle is turned down to 5/32". I did look at the gearbox to see if this could be opened out to take a larger diameter axle but it looked a bit too tricky for me. The bulk of the gearbox is brass but it has some tiny bearings for the axle to run in and some larger ones would need to be sourced and somehow fitted.
