Form a Hem ('Earnest Hemingway')

What happens here

This step, colloquially referred to as an 'Earnest Hemingway' bend, involves creating a double-folded edge, or hem, on the metal for added rigidity and a cleaner finish. Re-insert the previously bent metal piece into the metal brake, positioning it so that the initial bend can be folded back onto itself, forming a tight, approximately one-inch hem. Apply pressure by gently closing the brake, using a smooth and controlled motion to guide the metal. Once in position, execute the bend by operating the brake handle, ensuring the hem is cleanly and tightly formed. A couple of 'shakes' (gentle adjustments or taps) might be needed to perfect the hem.

Goal: To create a double-folded edge for strength, the partially bent metal is re-inserted and bent again, forming a hem.
