Sheet aluminium can be cut without the need for a 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.
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.
Prepare your work:
Mark where you want your bends.
Remove any unwanted corners.
Fold the aluminium:
Now slip the aluminium sheet between the two angle-s and roll the bender forwards while exerting downward body-weight pressure until the fold is 90 degrees.
Make a slot along one edge of your folder to accommodate the first bend.Position the first fold such that it will enter the slot when the bend is completed.
