> direct drive precision polished tungsten shaft

Isn't marketing wonderful. Who cares what the motor shaft is made of? (and why not ordinary steel? tungsten just sounds cooler? they want to reuse it for a lightbulb filament later?)

Tungsten will certainly isolate better than other softer metals. The entire product is centred around embedding vibrations into a physical object. The material that is used to transfer or isolate those vibrations is important especially at signal levels used in lathe cutting.

I suppose its better than it being made of rust like so many other projects like to advertise.
