Benfieldside’s Missing Signal
When my friends acquired Benfieldside, it had suffered a bit of damage, notably to its signals – in essence it was this that got me volunteered for their restoration! One signal that puzzled us, however, was the up starter which was missing altogether and we could not unearth any photographs of it. Ultimately, we decided that it should be a two doll signal to also control the adjacent bay (which did have a signal, albeit inoperative) – so I have set to in order to fill this gap.
The line is set in Cumbria and is an imaginary westward extension of the Newcastle & Carlise line. In theory, therefore, it should not have the heavy cast iron brackets that the NER used. However, in reviewing the NERA’s signalling book, it became apparent that there were quite a lot of strays of signal designs, so I had an excuse to build one!
As this particular signal is going to be platform mounted, I did not need to sort out a mount for it and moved straight to the post and bracket, the latter being by MSE which I had in stock.
I then moved on to the prefabrication of a pair of dolls, each with slotted posts. This is made up of solid square section filed to a taper which is then cut and each end then has a tongue filed on it onto which flat plate is soldered either side to create the slots. I used a variety of temperature solders to ease this process but it was not easy – I did have one gum solid which resulted in a need to dismantle it and start again! As alluded to in the previous post, as these are slotted posts I had to depart from my usual practise of fitting the arms after painting as it is not otherwise possible to solder them to the spindle for the arm.
As mentioned in the last post, I came up with a bit of a dodge to successfully (well, in two of three cases!) to solder the arm to the spindle without gumming it up. By extending the ear that forms the point at which the operating rod attaches to the arm forward a bit (see the line below), it provides a point at which the soldering iron can be touched. If you use a slight excess of solder this allows the heat to transmit to the spindle and make the soldered joint.
And this is what you get with a prefabricated doll, ready for the next stage of assembly.
And below of the pair of dolls now inserted to the landing.
Even at this stage, there is still a lot of building to do as there are handrails, the main ladder, steps and ladders to the dolls, the operating mechanism transferring the movement to the dolls all to do. In respect of the latter(I used rocking cams in this case – you can just see the use of some handrail knobs as the bearings in the photos below, the cams will be fitted after painting.
Slightly peculiarly, the NER built their landings in front of the arms whereas all the other signals I have yet built have these in the rear (excepting gantries, which can be either or both!). This view shows this most clearly.
The main ladder is not visible in the views as I have made this detachable because it is much easier to spray paint these (and better, it is not easy to get a thin coat of paint by brush application and it thickens up the fine detail of a ladder too much.
The grey primer is pretty cruel to modelling efforts but on the whole, I am pretty chuffed with this!
