Most frequently expensive sheet metal bending tools called brakes are used to bend sheet metal but you can also complete this task without one. The formation of sheet metal requires elastic plastic bending and stretching of the metal which contributes to springback. The average hack requires at least one angled metal part and the best tool to make one is still the good ol press brake. I ll be bending the metal using a jig just like the one in this ible i m a big fan of atomic zombie s builds.
