The result of a wobbling blade is that less teeth are cutting. If feed is
slowed down to a point that the same chip load is being achieved, the cut
will be the same as it would if the blade sere running strait. If the blade
has a severe warp (say 1/4"). the feed would have to be slowed even more as
more of the sharp corner of the tooth will be cutting. Even so, a smooth cut
can be achieved. Runout is not a big problem. End shake, however, is.
I think you're confusing blade runout and arbor runout. If the arbor were
perfect, then you'd be right; the tooth closest to the fence would always be
cutting the edge. However, the blade isn't perfectly flat AND the arbor has
runout. Therefore, the imperfections in the blade are sometimes offset by
the runout in the arbor, and sometimes not.
Then again, I may be confused. Truth be told, I've never seen a definition
of runout, and this is the first I've heard of end shake.
Having built machines professionally for the past twenty years, I can say
that I'm not confused. The confusion may well come on the side of the one
doing the measuring. How do we really know what he is measuring? Is he
measuring flange runout? Is he measuring arbor runout? If the latter, is he
measuring radial or axial runout? Put an indicator on the end of a shaft.
Push on the shaft in an axial direction. Does it move? If so, that is end
Since you've already ordered it, it appears you will have an excellent
opportunity to find out for yourself. ;)
Yep ... excellent blade; nice flat bottom on non-through cuts, like slots
for splines; and does a beautiful job of ripping edges for panel glue-ups,
which is what I use it for.
It should, as this is not an uncommon function of a good saw blade.
Actually, I have 2 blades that I use ALL OF THE TIME. They are both
Forrest WWII regular kerf 40 tooth blades.
I have 2 so that when one is being sharpened the other is ready and I have
no down time.
With a properly set up saw you will get shiny smooth rips and cross cuts and
So if you feel like using one blade for all of your cuts look at the
Forrest, if you can get it.
Count me among the very satisfied users. It not only leaves ripped
edges looking like they've been sanded, crosscuts are smooth enough
too. Only time I ever take it off my saw is for dados or to cut dirty
or salvaged wood.
