What's the proper way to deal with a hump in the edge of a board you
are jointing.

One that lifts the front off, then when you transfer to the infeed
side, you lift the tail off the table.

I've tried starting the board a bit over the knives, but normally
resort to my hand planes anyways.

Normally I'm pretty quick with a jointer plane now and always check the
edge with a starrett square to make sure. I shoot for no light, and no
visiable seam.

I learned the hard way when I hand planed my son's bed that .004 was
very noticeable.
