Help diagnose weird tablesaw problem

My first suspicion: the blade is dull.

Are these thin kerf blades?

Kindly,

The fact that the problem only relates to one blade suggests that the problem is with that blade…..Lee’s suspicion is logical. Is the blade dirty by any chance?

I’ve had something similar happen, and it WAS the blade. A dull blade generates MUCH more heat than a sharp one … it is digging away at the piece instead of slicing through it. That’s why the burn marks appear … and … wood begins to incinerate at about 450 deg F. ... so you KNOW it’s getting pretty hot. Along with the wood getting hot, so does the blade … BUT … instead of scorching, the blade, being made of steel will warp … and it can warp a LOT. I once had a cheap plywood blade warp so bad, it looked like a potato chip. I tried to get a picture of it, but when I got the camera, it had cooled off and was as straight as an arrow !!! If your blade is warping in use … it can be grabbing the piece and pinching it against the fence … by the time you shut it down to check alignment … it can straighten back up, defying detection.

Thanks all. The blade isn’t that old and hasn’t been burning wood so I didn’t suspect it being dull. I’ll try cleaning it and see if that helps, if not I’ll send it out for sharpening.

Not familiar with that acronym.

Possibly you shaking or not holding a steady line? I found myself fairly shaky and have had to adjust my feed techniques to prevent such things.

Thin kerf blades will deflect more than full kerf combo blades.
I still like the thin kerf blades becuase they decrease strain on the motor.

Pat, that was my first thought, but since it went away after changing blades it was probably the blade.

FYI, the rip blade is regular (not thin) kerf. I just assumed all the Freud red blades were Diablos, maybe not. I think it’s the heavy duty 24T.
