This involves making a score or cut line on the sheet where you want the bend to start. Sheet aluminium can be cut without the need for a guillotine or tin snips which tend to deform the metal. Since the stroke depth is adjustable on the machine air bending lets you bend sheet material to an arbitrary angle without replacing the die or punch tools. Bending these tempered alloys is not impossible but it is very difficult and will most likely require large bend radii to avoid cracking on the outside of the bend.

A siding brake bends aluminum or bendable vinyl siding to the angles you want using leverage from a hinged joint. Time to bend or nearly. Grab the top of the metal with the pliers as the section you heated cools off and pull towards you gently at first. For this you will need a table saw with a blade that has as many carbide teeth as possible and preferably sharp.

This weakens the aluminium and creates a fracture line. Stacey demonstrates a technique of how to bend a sheet of metal using a vise and 2 4 s. If you need to reheat the metal and redo the bend. The opening of the bottom die should be.

The metal should bend but only bend it as far as it goes without forcing it.
