In my limited experience with red oak, this results in bark which
is permanently adhered to the log. White pine is a different animal;
the bark will fall right off with time, though at the cost of borers
and stain, as you note.

It should arrive in the mail shortly. It's a 3.5-inch planer
which fits on the end of a chainsaw. You can use it to de-bark,
carve notches, and essentially do anything else which a portable
rotary cutter would do.

I'm not worried about open knots or checking; I'm going to use
them entire, in the round, as posts. They're big; structural
strength is not going to be an issue.

I guess I'll get to debarking, then.

I don't have a slick (they're very expensive hereabouts) but I
have a pretty large chisel which approximates one. I also have a
draw knife hanging around from the last de-barking effort. We'll see
how things work out.

These will be posts exposed within the structure, visually
inspectable at all times. I'm not worried about rot.
Red oak heartwood is beautiful, no question, but exposing it
would require actual sawing, and I'm going to use them in the round.

Yeah. If I had any of those, I'd use them. But the only pine of
decent size on my property is inaccessible, there's no cedar, and no
white oak. The red oak, on the other hand, was close enough to fall
on the house in hurricane, so I took it down for use in the structure.
