Diy built hydraulic metal shear. Hydraulic powered shears are available for up to 1 4 inch thick steel. In this video eastwood employee matt goes over one of his favorite tools to have around the shop and explains how to adjust the blades. This defect is related to cutting angle and plate strength.

Varying in size from small hand held metal shears and foot operated trim shears to high production in line flying cutoffs the modern metal shear has replaced the saw as the machine of choice for high production metal cutting. The sheet metal is no longer flat as its edges raise from the plan. This goes for the sheet metal as well. A throatless shear is a cutting tool used to make complex straight and curved cuts in sheet metal the throatless shear takes its name from the fact that the metal can be freely moved around the cutting blade it does not have a throat down which metal must be fed allowing great flexibility in shapes that can be cut.

If these shears become unwieldy by becoming too slack or rigid in their movement adjusting them is a simple process. To reduce this effect it is recommended to use a smaller shearing angle m and to hold the sheet metal with a back support.
