New Axles for horse-drawn buggies, carriages, Surrey, Wagons

The shorter spindle hubs are accomplished by moving the rear and front bearings closer together. The tradeoff is that the wheel hubs are a bit less supported for larger wagons and heavier loads than having a wider standard hub. You will need to use wheels with short spindle hubs on the short spindle axles and vice versa for the long spindle hubs.
