Flexicoil Truck for the EMD SW1500

cults3d

The Nasa EMD SW1500 Switcher I want to use to build my Nasa train has Flexicoil Trucks. Daniel Noree's model (https://cults3d.com/en/3d-model/game/openrailway-emd-sw1500-1-32-locomotive) is provided with Type A trucks. So I've designed new trucks (actually just the side frames). I've added slightly bigger wheels to match the size of the ones used on the actual SW1500. The small pieces are glued on the frame and the frame on the SW1500 truck assembly. The brake pipes are way oversized (hard to print a smaller diameter) ; it would be better to replace them with something smaller like a piece of copper wire. I've designed the wheels with semi circular axle holes. I've filed the end of the axles accordingly. It prevents the wheels from slipping on the axles as the torque is quite important. I you want to use a round axle you can bore the hole with a 3 mm bit from the inner side of the wheel : the first 2 mm are circular.
