Accurate bandsaws exist in sawmills, ganged bandsaws to slice the
cant (squared-off log) into rough lumber. They use the bandsaw to
minimize loss to the kerf, and have to cut to a minimum thickness to
keep the planing losses down, too. Wide blades, heavily tensioned,
close guides, and no tolerance for tooth damage. Most of my bandsawing
has been OK except for blades that get worn on one side more than the
other; they will steer toward the sharper side.

It might be nice to say bandsaws are used to minimize loss - but the were
developed for BIG Cants. Only in recent years kerf has been important as it
brought some more profit and less waste. The waste was used to heat and boil and
make other products.

The story tall blades had to go away with the Giant Redwoods. They were first
cut to length that a long team could pull then quartered to make it over the mountains
and through the round blades. This quartering was really tough and took time.
The band saw has ruled since. Much like the wire saw for stone. Once started,
the industry never looks back.
