I am having difficulty cutting 1.5 inch thick compound cuts to make chess pieces. I prefer to use 28 TPI reg tooth blade to make tight corners but the blade is too thin to make the 1.5 " cut without bending. The larger blades won't turn effectively. I have tried different speeds (Dewalt ) , different blades and cutting techniques (approaches). The wood I'm using is walnut which I've never had a problem with before. Any suggestions?
