In the previous front-on picture, are those wires and a resistor I see inside the smokebox? If so, how do you envisage protecting them from the gas burner?
If typical of most US steam locos, the generator would have run pretty much continuously as it would also have provided power to various other lights around the loco, principally in the cab. It has to be remembered that a full-size loco is invariably a lot cooler than one of our models simply due to good insulation, so there would be plenty of suitable routes for wiring.Maybe a silly question, but the on the model and the prototype it looks like there's a Stones generator behind the light, suggesting the headlamp would be electric? Where did they run the wires on the prototype? Assuming that there would have been some sort of control for the lights in the cab. Or might it have been as simple as turbine on, light on?
As I said, that is exactly what I did...It might be easier to find some suitably sized wire, that would look to scale being routed externally, rather than finding some that can live in a gas burner?
Yes it is a smokebox and yes they have quite a few holes. The flame Will have lost some of its momentum and heat by the time it gets to that smokebox but not a lot. On my RH Jack heat managed to get out below and cook the nylon gear on the SloMo so do not underestimate the latent heat around in that area. If you do not believe me very carefully touch it when in steam, if you linger you will get a nasty burnt finger.Thanks for the words of warning all. It sounds as though an external conduit might be the best approach then. That will be a shame. I'll hold off wiring it until I've at least had the chance to check the temperatures in the area.
I'm perplexed as to the warning about the smokebox hole though. The smokebox appears mainly decorative; it's formed of 1mm brass and has plenty of holes in the design. I can't see how my 0.5mm addition impacts it View attachment 271256
Here's the part removed from the loco. Am I correct in referring to it as the smokebox?
