Thin Kerf Saw Blades and Thick Riving Knives
Reading various articles on the benefits of thin kerf saw blades, particularly on portable table saws, I ordered a thin kerf combination and glue line rip blade for my new portable table saw.
The manual for the saw includes the detail: “You must select a blade with a Kerf width of .092″ or more…” Both blades I have purchased have kerf’s of .091″
I note in the QA:s a response indicating that “Most table saws equipped with riving knives offer a thinner knife as standard or as an accessory” Doesn’t seem to be the case with this portable table saw, at this time.
The same response indicates that riving knives should be as thin or thinner than the kerf of the saw blade.
Is equal width (Saw Blade Kerf and Riving Knife) really workable?
Is .001″ or .002″ wider Riving Knife sufficient to provide smooth “passage” of stock beyond the blade?
Is sharpening the front edge of a riving knife an alternative (although it would be modifying a manufactured tool)?
