The shim allows the full length of the workpiece to be clamped, but provides a small bend length so as not to excessively deflect the structure. Taper or radius the sides of the shim so they do not mark the workpiece. It is a process somewhat like hammer forming but you are locally bending with the brake instead of a hammer.
You have actually done it this way or is this an idea you are presenting to try out ?? ~ John Buchtenkirch
