If I understand you correctly you are asking if it necessary to rejoint a
glueup of several boards which would exceed the width of your joiner.

I think this would depend entirely on the quality and flatness of your
glueup. If your glueup has turned out with a cup or a bow or a twist how
else would you get that out unless you flattened one side on a jointer
(assuming you would not plane it out with a hand plane or use any of the
other devices I alluded to. I'm sure you are aware that a planer (absent
a
specially constructed jig--directions for which appear periodically in WW
magazines) can only dimension lumber (including glueups) which are flat on
one side. If your glueup is bowed your planer's rollers will flatten it
out
as it goes through the machine but the bow would spring right back.

Fortunately glueups rarely come out cupped or bowed, especially if you
have
been careful.

Good thing. The chances of me ever owning anything larger than a 6" or 8"
jointer are pretty slim. I would imagine that most of the people here are
getting their jobs done with smaller jointers. I do know a commercial shop
that has a very wide jointer (12"min, probably larger), but I've never seen
him use it; he always uses the 8" one when I'm around.

Hope that clarifies what I said.

Yes. Thanks.
