I had to disassemble my recently-acquired River Raisin Models Burro crane to prepare it for painting, so I’ve taken a couple of photos that will help others looking to install DCC in their models.
The motor for the crane is mounted vertically in the ring that allows the crane to rotate around its base. A wire comes up through the ring to connect one motor terminal to the pickup wiper on the insulated side of the model, while the other wire is simply soldered to the brass ring. I’ve unsoldered these two wires from the motor terminals and added the connector that came with my Lenz Gold JST DCC decoder:
I slipped a piece of heat shrink insulation around the four wires to help protect them as they pass through a slot I cut in the base of the cab. This slot allows me to install the decoder and its associated Power-1 module inside the cab – but outside the brass enclosure that surrounds the motor:
In addition to the slot in the base, it’s also necessary to extend the slot up the adjacent wall of the motor enclosure. The slot in the base allows one to slide the wires into position: When the crane is assembled, the wires pass through the hole in the enclosure itself.
I made several passes with a cut-off disc in a Dremel Tool to create this slot and hole. I then cleaned up the hole with another Dremel bit (a metal ball cutter) and filed the slot to make sure there were no burrs. The heat shrink helps protect the wires here too.
My friend Pierre Oliver suggested that for my mid-1950s era, an all-black paint scheme is the way to go, so I’ve sprayed the Burro with CN Warm Black – a custom colour offered by the Canadian National Railways Historical Association. It now looks like Darth Vader’s crane: it will need lots of weathering to bring out the detail.
