This was a customer commissioned job to convert the model to EM gauge. An 18.83 gauge set has also been done for this model.

Thermochromic PLA Gearbox

This was an idea we had as we had some thermochromic PLA at hand. The thermochromic PLA changes colour with an change in temperature. In this case the PLA changes from a dark green to a yellow/green when it is warmed above 32 degrees C. The lefthand image shows the gearbox at room temperature and the righthand image shows an increase in temperature around one of the gearbox bearings, by a change in colour, this change could be due to the bearing running hot for some reason.

It should be noted that the bearing in the righthand image was artifically heated to show what would happen if the bearing was to get hot.

All brass gear train for 'O' Gauge Heljan Class 33
