My guess is that if the fence is correctly aligned, the back of the blade
tracks **exactly** the cut made by the front, so no material is removed, and
no dust generated. If the fence isn't aligned, the back of the blade
removes material, which gets kicked up into your face to remind you to align
the fence...

Still, any case-hardening or stress in the wood will cause the board itself
not to remain straight, making the discussion a moot point.

Getting anal with the fence alignment can even reduce the above table
dust to almost nothing...

Ok, I'm confused. How will finely adjusting the fence alignment reduce the
dust? My experience with improperly adjusted fences suggests there may be
some burning and/or a slightly wider kerf cut than normal, but not a great
increase in dust.


I'm also interested in the answer.
