We had a six foot P3 stainless steel hinge to use on the 9′ brake. From the small brake on can see the middle will bow during a bend for a thicker material. We decided to place break the hinge up into sections. We put 2′ in the middle and on each side we have a 9″ space then a 1′ hinge section, another 9″ space and another 1′ section of hinge. This leave a 1″ gap from the outside edge to a hinge.
Here is Dan cutting the stainless hinge with a Dremel wheel (Always wear safety glasses when using a Dremel!! ask my Dad)
We used some stainless rivets to attach the hinges. We used the “yardstick hinge hole template” to drill the pilot holes. Stainless is a lot tougher to drill through than alumunim. Dan would spot face the hinges with teh template and I used the drill press to finish the holes. Here is four of the five hinge pieces:
Aligning the first hinge halfs with the fisrt angle wasn’t too hard. Match drilling through the 1/4″ steel angle was a pain. Dan used a older electric drill for this task.
Aligning the other angle with the hinge was more work.
