If you need to make a small metal box, there is no need to hire anyone to do it for you. No matter what the reason is that you want to make a box, you can do it yourself by bending sheet metal with a metal brake. You can easily transform a flat piece of sheet metal into a small metal box.

  1. 1

    Mark the metal. Measure 1.5 inches from the outer edges of all four sides of a square piece of sheet metal and make a dot with a marker. With a straight edge, draw lines along that mark parallel to the outer edges of the sheet metal square.

  2. 2

    Cut the metal. With metal snips, cut along one of the lines at each corner until the point that it intersects with the other line.

  3. 3

    Bend the metal. Put the piece of metal on the platform of the brake. Align the portion that you want to be bent with the platform seam. Take the brake bar and place it on top of the brake bar. Put the brake's levers in the upright position. Loosen the C-clamps and repeat the first two steps for each of the three remaining sides of the metal.

  4. 4

    Fold the squares of metal. Now that the box is folded, fold the squares of metal that extend beyond the side of the box snugly against the outside wall.

  5. 5

    Drill holes in the corners of the box. These holes will be the pilot holes for the rivets. Rivet the corners of the box to fasten the sides.
