John Miller of Tapco Tools used a short version of the Anniversary Brake to show me how to make a number of different flashings: sill pans, head flashings, and a brick mold trim for use with replacement windows.
The Anniversary Brake was introduced on the 50th anniversary of the invention of the portable brake. This new model sports several improvements to the original design: removable handles, jaws that open wider than normal, and a "hinge" that works by means of cams instead of the usual piano hinge. In addition to using the brake, Miller made use of a removable slitter and a Brake Buddy.The Brake Buddy is a hand-held roll-forming device that can roll various profiles into sheet metal – it's very slick.
