A pair of the pivot unit screw have pulled out the unit and damaged the chipboard. I had this on a couple of units and set them by routing out a 12mm hole and fixing some dowel in place that the hinge will fix to; but the last unit I’m looking at has a much wider area of damage (+2cm at the surface) so the dowel won’t be steadfastly seized in by the rest of the chipboard along its full length. What is the finest technique to fix a chipboard cadaver kitchen unit? I’ve bought few plastic wood filler but I’m not certain about the right way to fix it. Any kind of aid valued.
