Turn orange screw to clamp or release the yellow workpieces.
It is applied for clamping six cylindrical workpieces or a long plate of unhomogeneous thickness
Distance between two adjacent workpieces is 2a.
Length of the violet bar: a + 3a
Length of the green bar: 2a + 4a
Distance between revolution jpints of the cyan slider: 5a
Such dimensions make part clamping forces rather equal.
