HOW TO CUTTING&BENDING SHEET ALUMINIUM
Cutting Aluminium Sheet
Sheet aluminium can be cut without the need for a metal guillotine or tin-snips which tend to deform the metal.
With the aid of a straight-edge and a sharp knife "score" BOTH sides of the aluminium sheet. This weakens the aluminium and creates a "fracture line".
Place the "fracture-line" over the edge of a table and bend the overhang SLIGHTLY downwards. Flip the sheet over and repeat. After a few "wiggles" the sheet will fracture along the cut-line leaving a clean break as shown in the above photos.
With care and patience full-size sheets of aluminium can be cut using this method. Create a long fracture-line then progressively bend the sheet from one end to to the other.
Bending sheet Aluminium
The metal-folder is made from two right-angle sections of metal. My folder is made from aluminium but "angle-iron" is okay.
The spacing between the two nuts and bolts determines the maximum width sheet that can be bent.
