fwiw, my FB610 is not terrible vibration-wise, but certainly nowhere near as smooth as good old iron or my old DoAll metal saw.? I've never run newer saws like ACM, so can't compare to that.? So I tinkered a bit to try and isolate vibration on the Felder.? To my surprise, the motor is a major source of vibration.? I ran the saw with no blade, and the instant I power off the motor, it is much smoother.? ?I assumed this was a high-quality motor, but now I'm less sure.
I also had the thought of filling the column with concrete to add some mass and damping.? The Felder column is no doubt perfectly FEA-analyzed -- just stiff enough to tension a blade, and not an extra gram of metal to upset the bean counters.
