Since he has the tooth, and for the sake of my curiosity, can it be
brazed back into place, and will the bronze wick up into the joint? If the
broken parts were whetted with filler, could they be stuck back together
when both sides are molten? Will the bronze raise the gear?
The reason I ask it that it seems that to my uninitiated mentality that
bronze wicked in by capillary action ought to have almost as much strength
as the original part
