Help jointing a 5/4 twisted board

[Chris Friesen]

As others have suggested, knocking the high spots off with a hand plane will work too but it seems like a pretty "fussy", time consuming way to go.

Depends. If you've got a planing stop on your workbench, then it's just a matter of slapping the board down, grabbing a scrub or jack plane, and taking a few swipes at the high spots. With a sharp blade it's pretty straightforward to take off 1/16" at a time.

Just to add to Chris' comment, it usually takes me less than five minutes to take care of the high corners of a twisted board with a hand plane.

You'll have to decide if that is too time consuming for you.

This answer is sort of outside the box, but what I would do is to place the board on a known flat surface like another board and place a couple of shims under it to get rid of the rocking. Use double sided tape or hot melt glue to to hold the shims and twisted board in place on the sled board. Then run the entire sandwich through the planer to get one face flat or nearly so. Then run that face across the jointer to get truly flat before returning the piece to the planer for flattening the other side.
