This is pretty counterintuitive. I had a three-pound Estwing
drilling hammer. My favorite hammer. The task was to knock all forty
wheel studs out of the back end of a tractor. Then hammer in longer
ones. Brand new vehicle, so no rust.
Anyway, got a little tired after the first one, decided to use a
larger hammer. The guy I was working with had a five-pound minisledge
with a wood handle. I borrowed it and nearly knocked myself out cold.
Where it took my little hammer three to five hard hits on average to
remove a stud, it took his five-pound hammer five to ten swings, and it
clearly bounced a great deal further back each time. Whether it was
him, me, right hand, left hand, one hand, two hand, results were pretty
So how in the hell is it that a bigger hammer bounces back harder and
drives the stud less?
I'm mad about that, even if my hammer turned out to be better.
Damned head still hurts.
