I have a nice Dewalt DW733 planer that I use occasionally, new blades but I'm having trouble with the first 2 or 3 inches showing a recess when the planer grabs the oak. (I think it's the feed end anyway).

Is there a trick to keep this from happening? I've tried using very shallow cuts but still getting it.

Even trying to sand these out is time consuming.

Another trick some have used is to hot glue (or use superglue) longer
strips to the outside edges of the board. They have to be a bit
thicker than the board itself.
