Semaphore Signals - 4mm Scale (Mainly)


Recommended Posts

More for Stowe Magna.......

 

With the bracket signal completed, I've decided to deal with the other signals as a batch.

I have progressed as far as the "static" assemblies:

I showed the Rail Built post previously when describing its foundations. Here it is ready for cleaning etc. prior to painting.

 

The other three signals are ex-LBSCR square posts with SR Upper Quadrant arms.

The posts are 3D Printed by Shapeways - from Les Green's Shop : https://www.shapeways.com/product/P6AYJMKN5/2015-11-05-square-signal-post-v2?optionId=58364585&li=shops as are the Lamp-Bracket-Bearing

These posts are hollow to allow the optical fibre to be concealed.

The other components are from MSE/Wizard, Masokits etc.

 

Just one Westinghouse Ground Disc to add before cleaning, painting and adding the moving parts..........

Hi Steve, I've used Brian's square posts but how do you fix then to the metal base? Thanks

Hi Jonathan,

 

I'm not sure what "Brian's" square posts are?

Did you mean "Les's" - i.e. what I am using?

 

My method is to make a socket out of brass into which the bottom of the post is a good fit.

This brass socket is turned up to also support the Guide Tubes for the operating wires and has a shoulder or flange to allow it to be fixed immediately below the baseplate.

This ensures that everything is square and vertical.

The 3D printed post is turned at the bottom to make a spigot which closely fits the Socket.

I use Super Glue to finally fix the post in place.

This photo shows the Brass Socket soldered into the baseplate.

The Guide Tube (1/16in Brass tube) can be seen adjacent to it.

 

I hope this answers your question.

 

Steve.

Thanks, Steve. I meant Les, I don't know where Brian came from. Brain in a bit of fog since an op last week is my excuse. I never thought about turning a spigot but I would have to use a drill as I haven't a lathe but it would give the glue more surface to grip.

Having made working models of MSE's Midland ground signals but shied away from getting the weight bar working, I am much in admiration.

And finally ??.................

 

Tony has requested an additional signal for Churminster & Stowe Magna.

This is a Rail Built Bracket with the two Starters for the little terminus at the Aerodrome.

And finally a little video:

 

 

I now have a total of some 16 signals ready for delivery. They vary in size from Ground discs to a bracket with four arms.

Original plans for delivery and installation of the Churminster signals got put back by the first Covid Lockdown.  Let's hope the relaxation of restrictions allow our current plan to proceed in a few week's time.
