Hi All,The saw is a Powermatic 66 – gold color, saw blade is a Forrest WW II, wood is Mahogany.I have Aligned the saw top to the blade and the blade to the fence – running right ~ .001″ for both.The blade has <.001 of lateral runout, the arbor has < .001 of runout, yet when I rip the mahogany I end up with ~.010 of taper, which I cant figure out. and since the 2 edges are not parallel, the tenons I was cutting are off…I am out of answers here, does anyone have some suggestions?ThanksRay
