Fitting the stub axles

The stub axles support the worm wheel and spur gears. To remain clear of the body they can only extend about 1mm outside the chassis side.

I feel that I'd like to be able to remove the axles should the need arise. By making them from axle steel and running a 1.5mm drill bit through the muff, they should be a loose fit.

Then with the muff in the chassis, I feed a 1.3mm drill bit through, then feed in the 2 stub axles, separated for electrical isolation by a slice of styrene.

3 stub axles in place

Others make stub axles from old 1.5mm drill shanks. I can see that this would be smoother than axle steel, perhaps worth trying at some point.
