Yes, and yes. All we can say right now is that a full-kerf Forrest
Chopmaster (w/o stabilizer) cuts better than a thin-kerf Freud Diablo
(w/o stabilizer).
That said, I think I'll be investing in other Forrest blades.

Leave the thin kerf blades to ripping or gang ripping.
In addition to using a decent plate thickness limit the hook angle of
your blade selection so that the miter saw, coumpound miter saw or
radial arm saw does not overfeed.
consider from 5 degrees positive to 5 degrees negative hook to be in
the range with very good results near zero.

Generally a little wobble as a blade comes up to operating speed is
normal, the blades being hammered or roll tensioned to be stiff at
operating speed. Your description sounds like a bad tensioning job or
none at all, the blade is defective -return it.

Thanks for the replies. The Chopmaster has a 5 degree negative hook.
I may get a stablizer for kicks and see what it does to the diablo.
If I do I'll post back.

The stabilizer *does* make a difference. It isn't just marketing hype.

Oh, sure -- like I said, they're top-notch. Check out Ridge Carbide, too,
though. A few years ago at the Woodworking Show, I was in need of a
high-quality dado set, and had the opportunity to compare the Forrest and
Ridge sets side-by-side. The Ridge set actually gave a slightly smoother cut
with smaller "bat wings" at about 2/3 the price. I haven't used any of their
standard blades (yet), but if they're as good as the dado set...

No doubt you are -- Forrest blades are top-notch. It may be, though, that the
lesson to take from this experience is not that one should use full kerf
blades instead of thin kerf, but perhaps rather that one should use Forrest
Chopmasters instead of Freud Diablos. :-) Or perhaps that one should not use a
thin kerf blade without a stabilizer.

I find the Diablo one of the worst I've ever had for start-up flexing --
all in all, its only an "ok" blade in my book. I bought a pair for
gang use and they're not very satisfactory for that for tenons for that
reason. They are the only blade I've ever had that actually had enough
initial flex to strike the sides of the throat plate on the PM66 and
I've had the same saw w/ factory-supplied plate for over 25 years now
and they put the first real whacks in it it ever got...
