Table Saw Blade
 

What is acceptable wobble for a TS blade? .005" or is that
for the motor bearing? I just noticed my main TS blade isn't
straight; like it got bent out of shape and doesn't appear to
run true looking at it by eye sight.

TIA,

Thunder

I don't know what the tolerance is, but I do know that it is not visible to
the eye. If it is a cheap blade, toss it, if it is a good blade, send it to
Ridge Carbide Tools or Forrest for sharpening and flattening.

Acceptable is shat you are willing to put up with. For me, factory fresh
..001". My arbor was .0005 when it was new.

Hi Thunder,

Some of the better blades (Forrest, for example) are spec'ed at +/-
0.001" (0.002" total indicated reading). 0.005" for a blade isn't so
bad. Unless you really know what to look for, it would be hard to see
this amount of wobble by eye. If you can see it, it's bad.

Blades warp when they get stressed (thermally or mechanically). So, if
your saw is poorly aligned and you regularly see burn marks, then don't
expect your blade to remain very flat. Kickback is another great blade
bender which can be avoided with good saw alignment. It just doesn't
take much to warp such a thin steel plate.

You need to be able to distinguish between blade warp or other
arbor/flange problems. A 0.005" wobble in the arbor or flange is
unacceptably large indicating a serious problem (bent arbor, worn
bearings, etc.). Arbor and flange runout should be less than 0.001" on
a good machine. I have some video procedures which demonstrate how to
check it:

It's in the "Table Saw" section. If you don't mind watching all the
other table saw related alignment/adjustments then this is where you'll
find it. I'm working on seperating these (and other) sequences out
with new voiceover for The Woodworking Channel and will also post them
on my web site when ready.

Let me know if you have any questions.

Are you looking at it while running or just spun by hand. The thing to do is
to cut a groove in a board and measure the groove. I have a blade that has a
noticeable wobble when spun by hand though it cuts right on size.

I've a zero clearance and I'll give it a measure. The wobble is
noticeable when powering down. I've not noticed the wobble
until the blade is spinning down to a stop.

Thanks,
