Measure Bend Marks Three Times

Once your coil has been cut to size, it’s faster to measure each bend location individually than to mark them beforehand on the ends of the coil like you did when you cut the coil to width. Set the coil close to where you think it needs to be and pull the hemming handle forward, but not all the way into the locking position. Just pull it far enough so the locking anvil holds the coil snug but doesn’t pinch it tight.

Measure and adjust one end of the coil, then measure and adjust the other. Sometimes when you slide one end in or out, the other end tends to move a bit as well, so it’s important to double-check your first measurement to see if the coil is still where it needs to be. Hold the tape measure sideways so the numbers line up with the edge of the metal.

Cut to Width on the Brake

Step 1: Lock the coil into place with the hemming handle located at the top of the brake. Score the coil with a utility knife along the edge of the anvil.

Step 2: Once you’ve scored the entire length, pull up on the handles connected to the moving hinge, and bend the metal at about a 90-degree angle.

Step 3: Use your hands to bend it back down and separate the two cut pieces of metal.
