Recent tipsters have offered effective ways of supporting a sink cutout as the cut is completed (see Supporting a sink cutout
and Supporting sink cutouts
). But I think both of those methods take too much work. Instead, I make the cut a little more than halfway around the sink outline. Then I affix a strip of scrap wood to the cutout with a single screw in the middle. The scrap should be long enough to overlap the cut at both ends. Now I can complete the cut with both hands on the saw as the scrap supports the waste piece.
