Well, yes, but at the cost of a very tiny bit of added friction. Lubing makes it smoother, and if you hyperspin the excess lubrication out, it’s only a very minor cost:
But if you want PERFECT, zero-friction then you gotta completely get ALL the lubrication out. Just give it a shot, clean it with isopropyl alcohol. I’ll post an example in the above, try it myself and show you. It will be noisier, but your tolerance for that depends on you..
Terminator: The Sarah Connor Chronicles suggests that T-800s are made out of coltan:
John Connor: That’s coltan; if that’s what you’re made of, no wonder you’re so dense.
Cameron Phillips: Not density, heat resistance. T-600 models had a titanium alloy endoskeleton, but it was vulnerable to heat. Coltan alloys have a much higher melting point.
Coltan consists of the elements niobium and tantalum (both metals).
