At least we can conclude that the source of chakra is in the middle part of the body since we already saw that it has to rotated or something and then is send to each path of the body through the chakra pathway system, without a hand to give chakra it just leaves a hand size chakra amount left for extra use I guess.

@Tzao. If missing a part of your body causes chakra/power loss then by that logic shouldn't ten tails Madara lose half of his power/chakra after sasuke cut half of his body?

Chakra most likely is transported through the whole body hence why the chakra pathway is used. Basically transporting chakra to each part of the body and not the other way around. mental and phyical energy is mixed to use chakra so they just can't mix just like that. I think they have to be properly brought together(in the middle part of the body/heart)to then form chakra.
