Quick Chinese metal bender - GIF

[PJs]

an almost perfectly choreographed work routine no wasted movement I wonder if the foot peddle has a spring return for the pneumatic or hydraulic valve?
Note how the bend process begins almost exactly as the clamp becomes tight and returns without any lag time.

I think that is just the guys timing...based on the pile on the floor, probably an hour or 2's worth. After a few weeks you would get your giddyup dialed in...at least some people would. This guy is in the zone by the look on his face, even to the point of his toss backward at :09 he knows exactly where its going and still reaching for the next tube, knowing where it is. Economy of motion in 3 part harmony.
