Hello all,
I picked up a 10" 80 tooth Freud Diablo blade for my table saw this
weekend, and I noticed that when I turn it on, the blade wobbles a bit
right at the start and when slowing down, but seems pretty solid when
the saw is running at speed. This is a "narrow-kerf" blade, so I'm
guessing that the wobble is due to the thinner material used in
manufacturing (unless the carbide is the only thing that is thinner?)
I was wondering if anyone else has had this problem, and if so, does a
blade stabilizer help, or is there something odd going on with my saw?
It is pretty cold down in the shop right now, and it is possible that
the belt is getting stiff, but the Delta blade that I had in there
before never had this problem. At any rate, the cuts the thing makes
are absolutely beautiful, so I was planning on nabbing another one for
my miter saw, and it'd be good to know if I'm going to need a
stabilizer for each of them in advance so I can save myself extra
trips to the hardware store!
TIA

Two possibilities: 1) the arbor bearing of your saw is worn and has some
play that manifests itself when starting and stopping, or 2) the blade is
warped. You should check the arbor for excessive play or runout and if it
is OK, check the blade for straightness. You'll find procedures for this in
most tablesaw tuneup articles.
If it is the blade and you bought it new, you should return it. If you
picked it up used, that might be the reason it was available. Contact Freud
to see if they can straighten it. I know Forrest straightens blades...even
those manufactured by others.

In addition to what Max said you might try loosening the arbor nut,
rotate the blade 90 degrees, retighten the arbor nut (but don't
overtighten) and try again. If this doesn't work, repeat the process
by loosening, rotating 90 degrees and re-tighten until you find a spot
where it won't wobble.

I suspect you got it in one there... I torqued the sucker down
thinking that the last thing I needed was a loose blade flying at me
or sitting there while the arbor spun halfway through a cut- and
didn't even consider whether or not that could affect the geometry of
the blade. Thanks for the help! (and thanks to all the other folks
who responded as well)

Blades should NOT "wobble" at anypoint when the saw is running (unless
it is a wobble dado set)
Take it back and get a good one, that one is defective if this does
not happen with the original blade or any other blades on that saw.
Would not hurt to make sure the arbor flange is CLEAN, as that can
thru the blade out of true as well

It is possible to tighten the arbor nut too tight against the blade, These
blades are very thin and you can distort the plate,. I once did this to a
Forrest blade. Couldn't figure out why it was wobbling. Loosen the nut and
it stopped wobbling. Remember that the lock nut is left hand thread and will
get a little tighter when spinning, it won't come off.

I do not own a 80 tooth but I have looked them over trying to decide
between that blade or the 100 tooth oldham blade. If you look close
you'll find the laser cuts go beyond the center of mass so I think the
stabilizers would affect the anti vibration mechanism. A little wobble
that doesn't show up in the cut surface would not concern me, You might
try a grade 8 flat washer on the nut side of the arbor between the jam
jam washer and blade, (same as a small stabilizer to make sure it is not
as the others have mentioned about it being to tight. Good Luck...GJH.

FWIW, Prior to carbide tipped blades, the blades were made with a bit of set
in the blade that would wobble at slow speeds but when up to speed would run
true.

Snip

Maybe it is left hand thread. If he has a left tilt the threads are
probably right hand. Regardless the nuts always loosen in the same
direction that the blade spins when cutting.

I have the same blade. Never saw any wobble with 1 1/2 HP starting it and
don't use a stabilizer. Yes, it does make nice cuts.

Really, I have 2 Forrest reg kerf blades and both wobble at start up and
shut down. They cut ,,,perfectly. This is not unusual at all.
