When I widened the hole for my new kitchen sink, I cut the length too long. The sink now just barely reaches the side edges of the cutout. Is there anything I can do to salvage this situation? I have about 1/8" or less on each side to work with.
If your sink covers the formica ( I assume it is pb and formica ) I would glue a board to the edge. You could also add a board to the underside with glue and screws of proper lenght to help strengthen the edge glued board. After installation of sink caulk around all edges.
