In previous post I described my method of gluing up a board of strips of various woods, planing it smooth, cutting it in two, rotating the pieces 90 deg. and gluing the piecesytogether to make a bowl blank. A reply stated that they would not have rotated the pieces, as this could make it unstable. My theory was that it would make it stronger, kind of like plywood. Could someone explain how crossing grains causes instability. I am not gluing end grain in this process. Thanks.....
