I have a pair of Amal twin air levers, at some time in the past the longer bottom lever has been bent a little, a small bend near the circular part where the cable sits in the groove, and also a little bend on the bulbous end of the lever, the consequence being that the top and bottom levers will not pass each other, what is the preferred method of bending these back to the correct shape, clearly brass can bend without fracturing (once) as this has done so, my concern is if I attempt to simply bend it back will I be left with three pieces of metal?
