electric toothbrush drive train?
 

A while back some one mentioned that those cheap battery powered electric toothbrushes have a 130 motor on the inside. Looked at one in the store yesterday - Thought - there must be some sort of drive shaft to transfer the rotation down the length of the brush and then allow a 90 degree turn. Anyone pull one of these apart to confirm or refute my thoughts?


Looking at a shaft drive for an RC motorcycle.

I just took one of those apart, and all it is is just a axle with half of it cut off at the end, and it just spins it. It goes something like that...

i've noticed on my electric toothbrush that the tip only turns about half way and then turns the opposite direction. It doesnt really go in a ful rotation.
