I’ve finally blocked out the axles, too. It’s still one single object, so that the different parts have to be separated as objects and named accordingly later. I have blocked out the front axle according to the back axle visible on one of the images of Kent’s reference sheet and then mirrored it, but the front axle is simpler and seems to be thinner. This has to be fixed. The blocking was done just by eyeballing. The hub of the wheel served as the only orientation for the diameter of the axle.
