sounds good, I have a dremel and now the air die grinder, haven't boughten
any bits for the die grinder sides the stones that came with it as they
were pricey and I didn't know what I needed yet, maybe their's a kit w/ the
bits I'd need? (Eastwood?)

The drilling I was talking about is drilling through the 'four big end
journals' as Vizard says, worth 1.5 lbs and then consequently 1.5 lbs is
removed from the counterweights (by the balancer) so that adds up to a nice
reduction in weight.  The more I read it it sounds like machine shop work
for the drilling.  Correctly done he goes on to say how this can strengthen
the crank.  He talks about ~23hrs of die grinder prep for a crank, that's
the part I could probably enjoy doing myself once the end's are drilled by
a machinist.  Then I'd get the balancing done by a pro obviously.  Any good
before/after pics anywhere for knife edging etc?
