Sheet metal hand seamers are an extremely common means of bending metal in small increments.
Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape.
In other words if you re bending 1 8 sheet use a tool with a 1 8 radius to form the inside of the bend.
These tools are not found in big box stores and offer superior quality.
Most frequently expensive sheet metal bending tools called brakes are used to bend sheet metal but you can also complete this task without one.
This is done through the application of force on a workpiece.

If you re bending 0 020 thick material use a 0 020 radius.
Bending sheet metal by hand is a manageable task if the piece of sheet metal is small and thin enough to handle.
The force must exceed the material s yield strength to achieve a plastic deformation.
