Flying shear - GIF

[Bcampbell1989]

Another thing I found really neat about my experience with flying shears is it did 2 cuts in one stroke. the cutting die mechanism was cammed so that a blade would run straight across the top of the tube putting a flat on it before the shear blade came down and actually made the cut. Without the flat (cross cut) the shear blades would run off one side of the tube and break the blade and likely crash and destroy the whole die.
