I got started thinking today about how I throw the shuttle - what parts of my arm/hand actually get used.
It seems to me that there is only a very little wrist flex once I get up to speed. That the motion comes initially from the shoulder, bringing the hand closer to the selvedge. Then a slight rotation of the lower arm from the elbow and that the majority of the propulsion actually comes - not from the wrist - but from the index finger.
Unfortunately it would take a high speed camera in order to slow the movement down sufficiently to really see what's happening.
Of course a wider warp could change everything..............
Time Warp - wanna come to my studio?
