B is the splice rail, as A but cut back as shown. C, D, E are then assembled in a suitable jig. Assembled point rail D is as A but of the opposite hand, notched with a file to receive C. Assembled splice rail C is as B, soldered into the notch in D. Use high-temperature solder because the rail gets hot while sanding. If necessary stop and dip it in ...
