I currently own a JWCS-10 Jet cabinet saw which is about 10 years old now.
Over the past year or so I have noticed that when making a long rip cut, the
blade, from time to time seems to have a momentary oscillation (more like a
shudder) that lasts a fraction of a second then stops. This is just enough
to cause a ragged section in a long cut. This happens regardless of the
blade I am using, the wood species, or the speed that I advance the wood
into the cut.
I am beginning to think that the ball bearings that hold the blade arbor are
beginning to go bad. Anyone had this problem before? Any suggestions for
isolating the problem?
