Self-centering chuck of six clamping points

It is developed from the three-jaw self-centering chuck shown at http://youtu.be/0ERIZeZhckw A jaw lever (in pink) is pivoted on each green slider. Thus, the orange work (a stepped shaft) can be well centered and firmly clamped through six points. See real chucks: https://youtu.be/Gic4pCI9GuU
