I have a desalt power planner. Love it BUT! I thought it would take the CUP out of a run of wood/stock. IT WILL NOT the rollers alway PUSH it FLAT then to course you still have it when it comes out.

I have the same issue with a BOW but I made a SLED where I put the CROWN up on this SLED and shimmed up the HIGH middle area. screwed it down and shot it through.

Made it flat as a piece of glass. Then flipped it over and flattened it out to. ROCK SOLID FLAT LUMBER.

BUT I cant figure out HOW to do the same thing for a CUPPED board.

If there was a way to use some sort of SLED for that that would be great BUT less of like POURING some sort of resin to form fit under the CUP part to support the CUPPED part on the sled cant do it. Too much time and effort for cheaper gigs. I mean I guess you could do that… BUT!???

ANY ONE figure that out?

how thick is the lumber that is cupped?
Did you mean a “Dewalt” planer or is “Desalt” a name brand too?

You could try putting the concave side up, then shim under the outside edges along the length of the board on both sides to prevent them from flexing down under the pressure from the rollers.

Yes, it’s true a planer won’t make a board flat. It only makes it thinner.
You will need a jointer to make one face flat, and one edge square. Then you can move on to the planner.

If you don’t have access to a jointer there are workarounds like a planer sled, and tons of info exists on that topic.
My preference is to use a jointer for its intended purpose.

Good luck with it.

I do what Brian says, concave side toward the blades and shims along the edge.

You can tape or hot glue shims under the cup.

You can rip the cupped board in half before

You can remove the cup from one face of the
board using a hand plane.
