Default How much runout on TS is too much


"RayV" wrote in message
ps.com...

The runout measuered on the body of the blade is 0.003". I think this
is too much but it could be the 'silver' coating on the Avanti blade I
just bought.

Is 0.001" alignment close enough?
Is 0.003" blade runout too much?
Is it OK to have the dial indicator angled so the measurement can be
taken closer to the table or does it need to be 90deg?
(as seen here, but not my site)

Regardless of the slight differences you see now, how does the cut look?
Happy with the results? Stop fiddling.
A typical Forrest blade when new is with in .001". The arbor run out on my
saw when new was .0005".
When I check my fence alignment I make a test cut. If there were tooth
marks on the keeper side I would slightly adjust the fence on the back side
away from the blade. Tooth marks on the waste side, move the back side of
the fence slightly towards the blade.
Yeah, you waste "a" scrap piece of wood doing this and if your saw is decent
you only have to do this once every 3 or 4 years, maybe.

Regardless of what kind of measuring equipment you use to set the saw up,
you have no control over the fact that most wood does not remain dead flat
or straight to the extent that those tiny measurements that you tweak you
saw to come in to effect. They help but often wood can warp as you cut it.
Wood often will move during the cut much more than the tolerances that you
are looking at and then every thing becomes a moot point.

Or wait a little while and Ed will try to sell you an aligner that may or
may not help with the results of your cut.
