It is done...(well almost)

[brian_wagner at sbcglobal.net (brian_wagner)]

Not entriely true, in theory yes. But it is possible the interference of the
origanal hit, would have caused a change in the timing again. The force and
a brief instantaneous stop and restart along with the fact the lower cog was
loose may have have the rest from an untimely death.

IMHO
