Even though it's only a contractor's tablesaw it has been giving my good service, until now. Lately my TS has been doing something out of the ordinary. When making a cut, the blade will start vibrating (goes out of resonance, as it were) causing the cut to be ruined. If I take just a skim-cut, everything is fine but a full cut, vibration always sets in.
I use full-kerf blades, mostly Freuds but recently I started using a Forrest WWII (excellent blade!) and even this blade vibrates. But it had just started doing this towards the end of last year. Since the WWII was put into service last August, cutting some very hard woods, I just figured it was time for a resharpening and replaced it with one of my resharpened (by Forrest) Freuds. It too vibrated...
The next thing that came to mind was a bad arbor bearing, or some other looseness under the table but when I checked everything checked out to be in good shape, nice and tight. I then added a 3" stabilizer to the nut-side of the blade but it still vibrates, albiet not quite as bad.
Guys, what's my next step here. This was never a problem until maybe last November and it happens with every blade I have tried, from the WWII to the very first Freud I bought. I'm at a loss as to my next move. That little voice of mine is saying "bad arbor bearings!" even thought I cannot detect any play in the arbor...
Any suggestions???
Thanks!
