I have a new Grizzly 14 in. bandsaw. It's worked pretty flawlessly
until today. I have the stock 3/8 blade on it which again, tracked
and cut beautifully despite people's claims to the contrary. Today I
was ripping a 3ft. long 4 in. thick piece of oak, and the cut was
going perfectly until the last 3 inches of the cut, when all of a
sudden, the blad took off the to right. The blade bowed so hard that
the cut wandered off about 3/4 of an inch. I reset the guides,
checked everything I could think of, but the blade continues to dive
to the right as soon as I begin a cut. Any suggestions. Again, this
happened very suddenly. Could the blade have warped? Or just become
ruined so suddenly? It doesn't seem as the though the blade was
stressed/ overheated during the cut.
A nail's a good guess. If not, and as you say everything else checks out, take
a good, slow, close look at the blade. Both the teeth, and especially around
the weld.
(Did see that happen once, and found the blade on the side of the thrust
bearing:-)

Is it possible that you hit a nail or other metal object? It sounds like
something dulled one side of the blade.

take a look at the wood where the wander started. sometimes trees trap
rocks and nails and such...
