The brake in the shop is a Chicago W31 steel box and pan brake. In a box-and-pan brake (also known as a finger brake), the clamping bar includes several removable blocks, which may be removed and rearranged to permit bending of restricted areas of a piece of sheet metal or of already partially formed pieces. After bending, a box or pan form is then completed by screw, solder, weld, rivet, or other metal fixing process.

=== Bending Steps ===
#Ensure that your sheet metal is thinner or equivalent to 14-gauge sheet metal, and ensure that it is less than 48" in width.
#If making a bend for a box or a pan, adjust the fingers so that the equivalent width of the fingers is just shorter than your sheet metal.
#Adjust the clamping force and the clamping handle to allow room to insert your work piece.
#Insert your work piece to the line you want to bend, centered in the brake, and clamp your piece securely.
#Pull up on the bending handle slowly until your piece is bent to the desired angle, and slowly lower the leaf.
#Adjust the clamp handle, and remove your piece.
#Put back any fingers if adjusted, and deburr if any rough edges are left.
== Safety ==
#Always make sure your hands are out of the way of the fingers and all moving parts.
#Be aware of your surroundings to ensure that you do not bump others with the counterweight.
#If bending a small piece of metal, place it in the center of the brake. (If you don't it can damage the machine)
#You may not use the sheet metal machines without safety glasses!! (Should be obvious if you are following the rules of the shop)
