Next I perform the "root canal". I use my plasma cutter to
cut out
material along the crack. This will allow me to weld a stronger bead,
and hopefully bend the cutting edge back a bit. The cutting edge that
the old teeth were bolted to is only slightly bent. When performing the
initial weld here, I put a cable come-along between the edge and the
opposite side of the bucket. I also swung my trusty 8-lb sledge hammer
a few times.
