A recently purchased Ridge Carbide box joint blade (10″x40T, 0.125″ FT grind) produces beautifully flat-topped grooves with clean sides. However, the groove is overwide, about 0.142″. Swapping in a Freud Premier Fusion ATB blade leaves grooves which almost perfectly match the expected 0.126 width. This comparison suggests that
the problem is not with the 3hp Sawstop PCS table saw (alignment, etc) but that
the box joint blade vibrates a lot while the Freud does not. Ridge graciously gave me
a new blade, but the result is the same.
What am I missing here? Is it a common problem? Am I expecting too much?
