And so to the steam pipe to the cab from the dome for Yellow Peril. After studying two photos it is clear that there is some form of steam cock with a handwheel connected to lagged piping coming from the dome.
So 1mm wire, drilled 0.4mm on the end with 0.3mm wire soldered in, then the smallest hand wheel from an 00 mse point rodding set sweated on. The handwheel is a 4 spoke not three like the real thing but hopefully I will be forgiven that ....
