Correcting Warp

I tried to search the forum for help, but that didn't work. I would like to attempt correction of a warp in a work piece. I have a small piece (36" X 4" X 3/4") with a simple one-dimension bow warp. I need only one good side for my project. I've heard of making thin cuts on one side to flatten the bow, but I cannot find the proper technique for this. Can someone please give me some pointers on correcting this bow? Thanks in advance!!

Really need to know which way it is bowed. If it's a cup warp wet the concave side with water and let it dry. If it bowed from end to end along the 3/4" the only way to fix it would be to make the board thinner by flattening it on a jointer and then surface it to a uniform thickness. Probably the best solution is to find yourself another board. If it's bowed now chances are it's going to bow again after you put it into a project.

A picture or two would help everyone give you advice. Some warpage can be fixed with some hand planing. Some can be corrected with ripping or jointing. Fix depends on how the warp is. Piece might be firewood or stock for much smaller projects.

I've gone out to find myself. If I return before I get back, have me wait for me.

cupping vs bowed ......

A cup is curve across the width, a bow is a curve along the length. Neither of which is easily fixed by making kerfs, straightening or flattening and inserting splines with glue to prevent it closing back up. It just ain't worth the time and trouble, especially on such a small boards. Just get a new board that is not warped.

The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)

Thank you. Looks like a fix is not worth the effort. I'll get a new piece.
