Mainspring bridle

Brad had a vintage watch for repair that needed a new mainspring but instead of ordering a mainspring we decided to try to use what we had at hand  so he found the correct size mainspring but with a regular bridle, took some mainspring material shaped as a slipping bridle and drilled the hole for the rivet through both the rivet and the bridle at the same time.
