I've had good luck silver soldering in this situation - you can keep
the teeth cool enough so they dont' loose temper because the "low
temp" silver solder is around 1200 deg if I remember right. As soon
as the solder wicks, cool the assembly do you don't detemper the
teeth.

And I've also (when really annoyed) just zapped it with an arc
welder....
