in just that way about 6 years ago, and it's still holding.

But my wildest JBWeld story concerns a '69 Mercedes 220D. Fully qualified M-B Techs should avert their eyes and read no further, lest they suffer permanent emotional trauma:

About 15 years ago, a friend phoned from Frankfurt (he was a Captain on the then-new 767 route from Charlotte to Frankfurt) to say that his wife had a transmission failure of some sort with her diesel in a shopping center parking lot near our town, and he asked me to see what I could do to help. I found that the nut which holds the flange (to which the flex-joint bolts) onto the output shaft of the transmission had worked loose, probably long before, and that the wobbling flange had moved rearward about 6 mm and worn away the splines on the output shaft. After staring at the mess for some time, I decided that that last 6 mm of splines might have some strength left, so I filled the remnants of the splines in the flange with JBWeld and then slid it back into place and torqued the nut up properly. I then sent the lady home in one of our cars and told her to come back in 24 hours when the JBWeld had time to harden and we would take a test drive to see if there was any hope of her making it home with this temporary repair. Next day, it seemed to be holding, and having confidence in her smooth shifting ability (she learned to drive in a '64 Sprite!), I told her to drive very gently home and park the M-B until her husband got back and could get the transmission output shaft replaced.

Five years later, he told me he had sold the car because it was getting too rusty (only 450,000 miles) and I asked him how much it had cost him to fix or replace the transmission problem; he then admitted that he had forgotten all about my "temporary" repair job. In the meantime, 3 of his teen-aged sons had learned stick-shift driving on that car!
