During the week Dan aligned the second hinge to the other angle and match drilled them. While this sounds easy is involves having all five hinge sections joined with their hinge pins in supporting the angle in the right position wile match drilling.
This Brake design uses one of the angle pieces at the bending nose for the sheet metal. That is why we bought 1/4″ thick angle, so we could get a 1/8″ radius bends. Now standard angle does not have a full radius at the end of the legs. We broke out the vixen files and filed until we got a nice bull nose. Here is a little 1/8″ radius template from a piece of scrap.
Once we liked the bend radius we located this angle and drilled holes for the clamping bolts
Here is the completed Big Bend brake:
