I save pieces of broken rods to repair other rods. I have one rod been spliced back together in two places...still works great. I trim the broke edges to get them smooth and in plumb...the take a slightly simpler dia. piece from a old rod and cut a piece about 2 in long...use JB weld on it and insert it 1 in the two pieces of the rod I am putting back together...butt together and wipe off excessive JB weld. Cant hardly tell it's been broken.
