Dado blade for BT3000
LEE WARD
Save yer money and get a Router bit to make Daddos cuz its much less
frustrating! Of course if money is no object then drop about 200$ for a
good Daddo kit for your saw keepin in mind that some saws dont like
Daddo kits on them or sanding disks either and will start to runout at
the slightest provocation,,Daddos on a router are fast an easy once you
make the appropriate jig you can make daddos extremely accurately with
very little fuss all day long for cheap when compared to a decent
saw/daddo setup....I have a video and book showin two ez jigs for doin
daddos that really work........

I have a Ryobi BT3000 TS and wondering what the recommedation for a semi-good dado blade would be. Would 10" be best or is an 8" sufficient. Also am wondering if a low kerf might be best because of the lower power or doesn't that make much difference.

Ryobi has a 6 1/2" wobble dado that they recommend. Although I don't
use this one. I bought a 6" steel Craftsman stack dado ($30 on sale),
which works reasonably well. My only complaints are there are only
enough chippers to make a 9/16" wide dado and the bottom of the dados
are kind of ragged (not flat and smooth). I've seen this type of dado
sold with the Vermont American and Irwin brands (maybe others???) which
come with enough chippers to go up to 13/16" wide. I've seen street
prices for these from $50 to $65. These dados are the low-end. I've
been lusting after a 6" Freud Super Dado (stack) for some time, but
haven't been able to get myself to fork out the $160. Systematic also
has a 6" stack set for $140, which I'm told is pretty good.
I have an experiences with dados and BT3000 I'd like to share. I tried
the 7" Delta wobble dado but it was too big for the dado throat plate to
accomodate. I can see why Ryobi's is only 6 1/2". I'm not too crazy
about wobble dados (at least on this saw). They cause an enormous
amount of vibration and make a nasty moaning sound. I suspect that they
cause accelerated wear on the arbor bearing as well. The 8" dados
probably won't fit because of the small cavity around the arbor and
small opening in dado throat plate.
Based on my experience, I think your limited to either Ryobi's 6 1/2"
wobble or 6" stacked dados.
Hope this helps.
Opinions are mine, not my employer's.

Wrong, Robert. I had a BT-3K and I used an Amana 8-inch stacked dado. It
worked fine, and produced a nice, clean cut.

I use an Oldham 10" stack dado on my BT3000. It cuts 3/4" dados in oak
with no noticeable stress on the saw. Since you usually have a limited
depth of cut with a dado blade power isn't an issue. If you can live
with the limited depth of cut that you get from an 8" blade (about 2
3/4" on the BT3000) it should work OK.
The Oldham has about a 1/8" kerf on each blade, and does a good job on
my saw, though crosscut dados sometime leave a slightly ragged edge.

A ply "shim" can go between the blade pocket and sheet metal dust piece to
extend the capability of the arbor width. Works for me.

10"??? Maybe you mean 6" vs. 8". 6" will do just about anything you
might want to do. Where would you need the depth of cut of an 8"? Many
people buy 8" since it's only slightly more, but I think 6" is more than
enough.
Stay away from the wobble-types. Actually, I remember a recent ad for
an adjustable dado that claims to give flat bottoms. Might be worth
checking out. Decent stackable sets are made by Freud, CMT and others.

Robert:
I got the Frued 8" Safety Stacked Dado set for about $106.00 and it works
real nice. My BT 3000 came with two spacers and blade stiffeners on the
arbor. Before putting on the dado blades I first put on the small spacer
and one stiffener. The optional zero clearance dado throat insert can be
used as well.
I got the stacked dado after first trying a wobble cutter. Aside from the
lousie cuts, I was also concerned the vibration would harm the saw's
works.

Mark:
On table saws the standard throat plate must be removed to use dado
cutters. Ryobi has an inexpensive dado throat plate. I use it with my
Freud 8" "Safety" stacked dado cutters ($106.00) and get nice clean cuts.
The Ryobi BT3000 is belt driven and not direct drive.
Appreciate your well-informed evaluation of table saws. Ever use one?

This is the 2nd post in 2 days that I come across that claims that the
BT3000 is direct drive. What am I missing here? The BT3000 uses 2 flat
belts...
I don't own a BT3000 quite yet (another week maybe) but I imagine you
can cut dados using Ryobi's dado insert and ANY size dado stack quite
nicely, provided you don't raise it all the way which, frankly, I have
never done. Don't most people cut dados relatively shallow 99% of the
time? This is also the reason why the advantages of an 8" dado set over
a 6" one are mostly sales-and specmanship.

told that they recomend the 6 inch. After further discussion he decided
you can use an 8 inch as long as you dont raise it into the throat
plate. He actually thought the 8 inch might make a cleaner cut because
of the faster speed. Seems like you can use either, its just a question
of whether you need a cut deeper than you can raise it with a 8 inch
blade.

surfaces speed for a given rpm. Second is a flatter exit arc from the
workpiece. Both of these make for a smoother cut. The price differance
between the same quality 6" and 8" dados is not that great, at most
$25.00, so if a machine is capable of using an 8" dado I would recomend
it.

Larger diameter blades have faster speeds at the cutting edge. Faster
speeds generally mean smoother cuts. Also larger diameter blades
generally have more teeth which would result in longer use between
sharpening.

However, the faster speed may be a problem for the BT3000. I called
Freud and asked their opinion on this and they said that because of
the speed that the BT3000 runs at it should not use an 8" dado set.
They said that the 6" would be fine though.

I also have the 8" Freud stacked dado set for my BT3000. It works okay, but due to the small size and the shape of the cavity around the arbor, I cannot put all the supplied chippers on at the same time. That is, I cannot do the max width cut (13/16", I believe) on a shallow dado cut. I believe that the widest cut I can do is 11/16", which is fine for most things. If I had to do it all over again, I would buy the 6", because I have not yet had a need for the extra depth cut provided with the 8".
