Well, I invoked my unlimited modeling license and changed my mind on the trammer. We designed and built a completely different machine from scratch.
This is the first Wall Wart Underground Trammer.
I had this dead wall wart that was asking to become something useful again. The razor saw opened it up and all the innards came out. Then it was sectioned to make it narrower. This became the 'battery case' for the trammer. A bunch of bits of plastic from one of those pill boxes and some ball point pen parts and a large button and we have a trammer!
The red thing is the rear headlight. It can be swiveled front or rear or to any position to use as a work light. The seat is a large fake wooden button for the driver's butt.
The brake wheel is the center section from a spare chrome wheel from a car kit. The throttle control is the pocket clip and a section of ball point pen.
The flat car is made from stir sticks, some wood and a couple of axles from an HO car. It should hold 9 of Miner Mike's 'pails' of ore.
This design is made for a single 10 hour shift in the mine. The battery pack housing is extra large so they don't have to swap batteries. Now for final paint, some couplers, weathering and a test run!
Oh, the driver is one of those little Chinese unpainted people. His arms and legs were cut off and he was reformed into a sitting driver. Some glue and the saw dust filled out the necessary places.
