This was also a “how-to” example in a fora to show people that it can be done without any fancy tools, or even machine tools like milling machine, lathe and drill press.

First order was filing the recess for the points on both stock rails, tack them in place with a few spikes and solder to the anchor points.

Next the frog rails, in this case one rail is stepped into the other.

Followed by the closure rails.

The point rails are hinged with yet another one of the brass screws serving as the swivel joint. A small hole is drilled through the base of the rail into the web, a short piece of brass wire is the pin.

A spike secures the end of the point rail in the swivel without restricting the motion.

The throwbar is made from PC board with a brass reinforcing tube epoxied to the base. Brass pins protrude through the tube and the PC board through the foot of the point rail and are soldered, then trimmed.

One of the Dremel reinforced discs cuts the correct width gaps to use 1.5mm styrene strips - glued in with CA - to insulate the frog.

After fitting the guardrails it’s time to strip off the cardboard and then ....

.. check the fit of the result.

Left to be done: electrical connections and a small adapter, in lieu of the baseplate, to hold the toggle switch.

Total elapsed time: 25 hours including all the daily routines that have to be taken care of i.e. cooking, walking the dogs, reading and sleeping.
