I was thinking about the difference between a jointer (powered) and a
plane. A jointer has the outfeed table level with the blade so that as
the work passes over the blade and onto the outfeed table, if the
operator uses good technique to keep the board flat on the outfeed
table, the board pretty much has to come out FLAT.
A hand plane on the other hand isn't built that way. It has a
projecting blade. So unless the sole of the plane is extraordinarily
long, how can you get a perfectly machined straight board? Just for
grins, I was using a tiny hand plane to plane the edge of a board and
found that no matter how hard I tried, the small plane "unflattened" the
straight edge I started with. The more passes, the worse it got. How
long of a plane do you need to get a perfectly flat result on say a 2'
board? a 6' board? Is it MOSTLY technique, or do you have to have a
reference straight edge and keep checking your work constantly as you
plane? OR do you just take a few light passes over an essentially flat
board to start with, and know that it is flat? In other words, when I
use the jointer, I KNOW it's flat. I don't have to check it. Can I do
the same thing with a plane, or do you have to stop, eyeball it with a
reference straight-edge, and then touch it up an little here, a little
Lay it on me, WW gods! :)

You are new here ;-)
For the first part, I agree, the name does not explain the working of
a jointer plane.
'Automobile' doesn't tell us anything about internal combustion or
differential gearing, however, we understand it to mean a self-propelled
vehicle. Nor do we need to understand how it works to know THAT it works.
I will make the huge assumptive leap that a power jointer is called a
power jointer because it performs the task performed by its predecessor,
the jointer plane. If, by 'jointing', we mean 'truing an edge square to
the face of a board', than I think it is indeed obvious that the expected
result of using a jointer plane is a squared, true edge.
Forgive my sarcasm in the initial post. BAD's unwillingness to make
any effort whatsoever in finding an answer to any question that pops into
his head, other than asking someone else to take the trouble, is like a
blackberry seed in a wisdom tooth. Not painful, but persisitently
I don't think so. But it was a nice try.
Automobile is auto-mobile or self moving/motion. Just like autograph is
your self written mark and autobiography is your self written story.
Back when the term was initiated all self moving vehicles, including the
electrics and steamers, were called automobiles.
as usual Scott is worthless at answering any woodworking questions,
which is why he is my premier plonkee.
I'm trying to understand the mechanics of planing to understand how I'd
get an edge as flat as on a power jointer, using a, say, low angle block
PLEASE try not to quote him... :)

It sounds like you might benefit from a little light reading about the

there is a lot of anal talk around here. why are there so many
"preverts"? NO, that is NOT a typo; anyone care to guess the origin of
that usage? Non baby-boomers need not apply...
