Maximum mild steel thickness you can cut with this machine is .06" x 12" wide
Maximum stainless steel thickness you can cut with this machine is .04" x 12" (ask before cutting stainless steel)
NEVER attempt to cut round stock or wire on the shear.

Training

Operation

The sheet metal shear is human powered. You will be pressing down on the foot pedal to move the blade that shears the material. The upper rail has two handles for clamping down your work prior to shearing.The manufacturer rates this shear for 16 gauge mild steel but it would be very difficult to cut a full width of material with this machine so we are limiting the width to 12 inches. It is recommended that you stick to thinner and smaller pieces of material when using the machine. This machine is not designed to cut round stock and it will ruin the blade. Keep body parts away from the blade at all times. Don't stick anything you wouldn't want cut off under the blade. This machine is not designed to cut round stock or hard materials and both of these will ruin the blade.

Demonstration

For the demonstration you will need to show understanding of the machine use and setup. You will need to select an appropriate piece of material for the demonstration and make a safe cut. By placing a mark on the material you can demonstrate your ability to align the blade with the cut line.
