Found on YouTube: home-made metal brake / metal bender.
Does involve use of arc welder,
so be warned: flashing images.
To me, this is quite an ambitious project but the end result looks quite effective. Having said that, the overall approach, design and assembly might give others here a few ideas for alternative but similar methods.
