Preparation for lighting

Milling of light ducts

This milling is done transversely, only in the necessary places. The milling depth is flush at the ends (see photo).

In green, position markings drawn on the MDF protective plate — the precision does not need to be very high; in red, the transverse movement (ø 6 mill bit); in blue, the machining depth.

Wiring of the bogies

I choose the method of a wire wound on the axles, because soldering on the bearings flush with the plastic would be too risky. The copper tape “collector” (1) is placed underneath, as above it would conflict with the body supports. However, the wires pass through a ø 1 hole (4) for more discretion and to avoid soldering fatigue. They are glued with a dot of CA (3) on the “brake disc” to prevent them from touching the wheels when pivoting.

The wires pass through the chassis at (2) and emerge in the technical rooms or toilets. The floor bushing is stuffed with a Patafix (Blutack) “seal” to limit the movement of the wires.

The holes left by the sawing of the pivots are not very discreet. A small plug will correct this.

Hole in the floor

The plugs are ø 3.5 die-cut in 1 mm thick polystyrene. They fit by wedging into the hole. They are painted in Humbrol slate grey.

Lampshades

To ensure that the LED light only illuminates through the “floodlights”, it must be prevented from passing over them. I therefore provided lampshades, polystyrene strips 4 mm wide and 0.5 thick, glued along the light ducts with Kristal Klear.

Note the 3 mm wide oblong hole in front of the foolproof, for the LED that illuminates the platform.

Hiding the lamps

I have noticed that the light from the toilet comes through the lamps which seem to be on! We need parts to cover them up. They are made with 5 mm wide strips cut out of a CD case. Two 1.2 mm thick layers are superimposed, one 20 mm long and the other 8 mm, so that the inner relief of the lamp can be passed over.

Lamp cover parts

The two parts are glued together with Kibri liquid glue. Gluing into the coach is done with thin double-sided self-adhesive tape.

In the following photo a cover is mounted on the left, not yet on the right. Please note that I have only mounted these parts on the toilet side, which is lit, while the other end does not need this.

Mounted cover

Be careful that the covers do not protrude beyond the top of the body, which would prevent the roof from closing properly.
