Main Signal Construction

the post. These then extended below the baseboard in brass tube which was formed in a 90 degree radius. One end of the brass tube was glued to the base of the signal, the other end epoxyed on to the top of the point motor. The brass rod being feed through the tube was now in-line with the point motor’s operating rod.

A small length of double sided copper clad board was used to make the connection from the 0.020” operating rod to the point motor operating rod. A suitable hole was drilled so the board fitted over the point rod with the brass rod being soldered to the correct end of the copper board. Before any soldering was done the travel of the point motor was tested as if the travel was too much the rod would be pulled out of the holes in the cranks etc. Small sections of Evergreen styrene were used to limit the travel. Once the setting up was completed the signal control rod was fixed with solder. The point motors were operated by momentary action centre off miniature toggle switches. Although a bit  noisy, the operation is near perfect.

Part of the development of the railway was to have a set of working signals. I was going  to use the MSE range of kits for all the signals, including the ground signals. The next problem was to decide how they were going to be operated. Was I going for the ‘bounce’ effect or the straight forward operation. After much thought and looking at using springs and other gadgets, I decided that the ‘bounce’ effect was out of the question. The final solution was to operate the signals by 0.020” brass wire, as used in other control applications, operated by a Hornby point motor. The motor was mounted under the board by drilling 4 holes in the MDF that corresponded to the locating lugs and glue them in using Epoxy Resin. The brass rod was used to operate the cranks and ultimately the signal  arms and was held in position by ‘eyes’ fixed into
