I'd like to discuss forged butterfly hinges. I used to wonder why 18th century forged iron butterfly hinges on drop leaf tables rarely survive, i dont wonder anymore. In addition to being very thin/delicate, theres another problem. If you click the link, then the pic on the left, it will enlarge. Notice the right wing of hinge wraps around the barrel/pin of hinge and then is forge welded to the underside of hinge. What happens at some point is, that weld begins to separate and when that happens, that hinge aint long for this world. I wonder, can that weld be restored-rewelded without destroying the hinge, or no?
