With the boards cut to length, the next step to building slab-style cabinet doors is to make sure that the edges of the boards are flat, straight and square to the faces of the boards.
This is a two-phase task. Begin by "truing up" one edge of each board on a jointer. If you don't have a jointer, you can perform the same task with a table saw jointer jig (as shown in the image above).
After one edge of each board is flat, straight and square to the face of the board, the opposite edge can be trimmed parallel with the first on your table saw. Adjust the fence so that you can take off a minimal amount of stock, but enough that none of the factory edge remains.
