Q: Can someone give me a few common techniques people use to run electrical wiring through a rotating object (like a propellar)? Let me give you an example of what I'm talking about.... Lets say you have a ceiling fan, and you want to mount light bulb sockets on the tips of the fan blades. How do you wire the sockets while keeping the wires from winding/spooling around the fan? Is there a common electrical doohicky people use to do these kinds of projects?
