Bending Aluminum Enclosures on a Homemade Brake

To bend 3mm aluminum plate to make custom project enclosures, British DIY audio enthusiast Rupert Hirst starts by cutting a channel along the inside of the intended bend, on a table saw, to a depth of 1mm, with a blade about 3mm thick. Then he uses a homemade bending brake to actually form the bend. The results, as you can see, are really impressive. [via Hack a Day]
