Has anybody done this or know what to do? Iam modelling LMS 1930s so could probably get away with either the old style complete rotating signal (where the whole thing moves 90 degrees) or use the revolving disc type where it revolves around a horizontal axis about 45 degrees.
I would imagine the former are easier to animate and I was looking at the Switchmaster motors which do 4rpm and therefore would take about 4-5 seconds to rotate the whole unit 90 degrees. This could easily have a brass tube connected that runs through a basic brass bushing inertered in the baseboard and could be removed for maintenance if required. It could be illuminated if required too however I am not sure of the lighting arrangement on the earlier tyes, the newer discs had a white light when "off" and red light when at danger which would be easily replicated with LED.
I assume that home made units of the second type could be made with some brass gears soldered onto the shaft of the signal disc and the motor shaft at 90 degrees to each other and this would change in about 2-3 seconds which is reasonable if both gears were 1:1 ratio.
Anyone know where these type of things are available from? Do I need to make my own (not likely!)?
