A problem arose on board three when we noticed one of the moving blades of point three had become unsoldered. To fix this meant removing the point from the board and then removing a very small rivet and then resoldering the blade to a new hinge rod, as it was impossible to do in situ. It was then necessary to replace the point so that it lined up with both sets of rails and then reconnect all the wiring. This was successfully accomplished and operating properly.
