Now that you know your bend allowance take your protractor and draw a clear line with your marker across the point at which you will bend your sheet metal. Then use your bend allowance to draw your second bend line the intervening distance between your bend lines bend radius. You d probably air bend by using a 3 0 in.

It provides a step by step explanation with some tips along the way. Grain direction bend line should go across the grain for the best bend having said that a typical sharp 90 bend on a piece of 1 8 aluminum sheet should be a minimum 1 8 inside radius use either 3003 or 5052 ideally the bend line should go across the grain.

This weakens the aluminium and creates a fracture line.
