My Dark Diesel Side

[Schraddel]

The next step in the life of the ALCO RSD-5:


Here i prepared warm white 2mm LEDs to fit into 1.5mm bores by filing them down. They are intended for the headlights. The massive brass castings on the model patters dual style headlights. And drilling 2mm bores into them will deface them, 1,5mm is the right diameter. And for not having LEDs with 1.5mm diameter, i have had to reduce the diameter. Two of this reduced LEDs will be fitted into one headlight casting.





The it was time to chose a speaker an the mounting place for it. Here in the hollow tank is enough space for an Knowles Dumbo type speaker mounted in a larger enclosure.





After some grinding of the upper edges of the tank the speaker enclosure fits neatly. The fixing was made with a piece of double side sticky foam tape.





Under the shell space is scarce. Onto the motor bracket a kind of decoder carrier made out of 0.4mm waste brass sheet. The decoder was also fixed with double sided foam tape. I made several bores into the motor bracket and decoder carrier to guide the wires to fix them in place. A huddle of wires will be very bad in this brass case. You remember this is no plastic shell, but a brass one and brass is electrical conductive and so you have to made some extra precautionary arrangements in the limited available space.
On the chassis above on the left side a 3-pin socket is fitted for the lights. This enables me to demount the shell lateron without soldering actions.
Right is an capacitor with 2200 microfarad capacity.
