J-B is some amazing stuff. And congratulations on fixing your own stuff. I remember when you had to improvise because all these repo parts suppliers weren't in business.
In the early 80's a friend had a '46 with a non working regulator. I took it apart and found the gears stripped. I was taking machine shop at junior college so I took it to class. I made a cutting tool in the shape of the gears, then filled the gears with brass and re-cut them. It worked like a champ. And I got a grade for it.
