I have a recurring problem that has been haunting me for years that i hope someone could provide a solution for - saw blade flutter on my table saw. Most woodworkers have probably experienced this at one time or another while ripping - the blade will be cutting fine and then suddenly it will "flutter" in the cut and produce a wider kerf. I've had this happen with newly sharpened blades, blades with and without stiffeners, on thick and thin wood, hard and soft wood, and even while making my initial cut on a ZCI (which pretty much defeats the purpose of making one!). I am a machinist by trade and my 3 hp cabinet saw is dialed in to within a couple of thousandths, so alignment can't be the cause. This phenomenon is driving me crazy and I'm looking for causes and solutions - please help!!!!!!!
