We are replacing preformed cabinet tops in kitchen and found the tops have a bow in them. We have a seam where one piece was cut & we have routed underneath and bolted together. The seam looks good. However, the bow falls where there is no bracing in cabinet to fasten the top down. The pieces are all cut and laid out but not fastened down. They seem to fit good & have no pressure at any point. Is there a suggestion
to help take the bow down at this seam area?
