Dan, that doesn't look right.  I think the weight ratio between aluminum (6061),
and Iron (or at least mild steel) is about 2.9 to 1.  That is, an item made of
aluminum weighing 1 pound would weigh 2.9 pounds if made of mild steel.

That would mean the 97lb aluminum block would weigh 281lbs if made of steel; or
the other way around, the 127lb iron block would weigh 44lbs.

Can anyone out there verify this?
