That's BeiErl, actually... :)

D'oh!  Great idea!

Just a side remark on hammers, energy transfer and impedance matching for
those who may not have thought in these terms...if you want to move
something, use a BIG hammer relative to the size of what you're trying to
move (in this case the innards of the impact driver).  If you want to
change the shape of something, use a SMALL hammer.  The smaller it is, the
more local deformation you'll get vs. more general deformation.  If you
want to impart maximum energy into the system, use a hammer of the same
mass as what you're hitting (this may also be the optimum -- if practical
--  for moving things, not sure but seems likely).
