Friction weld for a wear-out part? INSANE!

To those not familiar with friction weld the process is as follows. Chuck the two parts to be joined (they must be rotational parts) into the friction welding machine. One part is held stationary while the other is spun to high RPMs. At the appropriate pre-calculated rotating speed the drive motor is turned off and the two parts are forced together under high pressure. The friction of the parts rubbing together is what generates the heat necessary to melt and fuse the metals.
Using welded washers to retain the U-bolts is equally stupid. Obviously no one ever considered the need to perform any maintenance or repair in the future.
Glad you got everything sorted out. Your well documented challenges and ultimate successes will certainly help many others.
