Yes, I know that. I was simply responding to Micheal's comment about an
extended table by noting that I am already using one. While it, by
itself,
does nothing to flatten the board, it does provide support for the sled.
When using a 6' sled and 8/4 boards like I am, it's nice to have a few
feet
of solid support before and after the planer instead of relying on the
relatively short planer infeed and outfeed tables.

OK, ;~)Â* Actually I have a 15" stationary planer with fold up/down in
feed and out feed rollers/tables that are about 2' long.Â* They work just
fine and I do not worry with them being on the exact same plane as the
planer bed/table.

FWIW the sled you have and the one I am talking about are completely
different.Â* My sled travels through the planer at the same rate as the
work.Â* I use the wedges to keep the work from moving up or down, because
of bow or twist, between the sled and the work.

His "sled" does, too, Leon. He's just done basically like I described
with also making a false table but the sled is the 2x under the
workpiece and it progresses thru the planer carrying the work...you just
dispense with the lower false table.

What isn't shown in the picture is just how he did actually do any
shimming when planing "in anger"; he just has the two pieces laying on
top of each other as all the picture illustrates is that the two don't
lay flat face-to-face after he did make one or more passes to try to
flatten.

What we've not been able to see is an actual working pass.
