I have a Freud 508 stacked Dado. It had a high recommendation and did
do a good job on some dados I did WITH the grain. I tried to use it
on some oak cross grain and had some pretty bad tearout. The response
I got was to use a dado with positive tooth angle. Well, I have a
Sears wobble dado with positive tooth angle that is about 25 years
old, but I was told that these had the problem of creating a very
uneven bottom cut on the dado. Thought I would try it anyhow. Lo and
behold, the bottom looked VERY good. After looking at the design, it
appears that the teeth angle to the outside on each side that wobbles
out. It SHOULD make a pretty square bottom and DOES. Also the
vibration does not seem to be any worse than the stacked dado.
Anyway, I would like the group's experience with and recommendations
of dados that do a good job on cross grain. Also would be interested
in comments on my experiences with my wobble dado. Am I observing a
fluke in my wobble or are there others out there that have had similar

That's not a dado, that's a groove. <G>
Freud should change the name from dado to groover, if they expect you
to only use it with the grain.
I have a Freud stack dado that works great, can't remember the model
number. Are you sure something else isn't wrong?
I just found, sometime in the last 6 months, that a dado with the
grain is a groove. Thanks for reminding me. That makes my problem
even more of a concern. The stacked dado is a 208M. I tried to
remember it from memory, and you can see the result. It is an 8"
selling at Home Depot for about $80 as I recall (probably can take
that with a grain of salt also). It got very good reviews in one of
Freud confirmed I would have tearout at the end of the cut, but not on
the surface of the board, which is true. The recommendation was to
use a sacrificial board at the end of the cut. I think a positive rake
angle on the wobble helps to keep that from happening. I remembered
that I was always pretty happy with my sears wobble, but the bad press
in the newsgroups and elsewhere led me to purchase the stacked dado.
