With my TS, I need to make some crosscut 1" wide dados in a 1" diam dowel,
about 6" long. The dados will be about 3/8" deep. I have a Freud stacked
blade dado set. I am concerned that once the teeth engage the dowel, the
dowel will start spinning. At least it will tend to spin. Even with some
small rubber-footed clamps I am not sure it will hold. To anyone who has
done this, is the torque a substantial concern? Any suggestions as to how
to do this safely? TIA. -- Igor
Although I haven't had need to do this, I have
read somewhere about this method:
Using a sacrificial 2x4, rip a 45 degree
groove down the middle - use 2 cuts and make
it large enough so that the dowel is nested
in it about 1/2 its depth (or more).
Fasten the dowel from the back of the 2x4
with a few drywall screws (shallow enough
to avoid the dado of course.)
Run the dados.
Seems like it should work safely.

Sorry! For some reason, I read "TS" but was thinking "RAS".
However, I think the method would work ok if you
simply "buried" the dowel deep enough into the
2x4 so that the 2x4 contacts the saw surface,
then flip it over so the screws are on top.

The OP wanted to dado 1 inch wide, so multiple passes
would be needed. I think you would need to lock/register the
dowel somehow. If you're talking (say) 3/4 inch
or less (ok, 13/16) then a single pass with
"holding/clamping" would be fine (using a sled).
Of course, you would work with long dowels, then
chop them to the desired 6 inches.

Having used this practice in the past, I prefer it over V blocks.

With a decent crosscut sled (just for dados) and a sharp bladeset, I would
just hold and feed. The sled will provide the safety margin.

I actually had the same problem a while ago, while making bench pegs..
mine are 3/4", so I stacked 2 pieces of 1x3' about a foot long and
drilled a 3/4" hole through them, then connected them with a 1x6" the
same length..
What I ended up with looked like an over the fence push stick with a
big hole in it.. *g*
I'd stick a dowel in the jig, hold on to the long end, and slide it
along the fence through the dado blade....
The 1x6" worked to get my dados where I wanted them in the dowel, and
after each dado I cut the dowel on the RAS with a stop block, then
stuck the end of the dowel into the TS jig and did the next dado..
Repeat until you have enough dowels dado'd or run or of stock.. lol

That may be slightly easier using two scrap boards instead. In either case,
his approach is pretty solid. Any type of jig that locks the dowel in place
will work, and it's possible to do that using clamps, instead.
For instance, my crosscut sled has provisions for two wood faced clamps to
lock down pieces. By using V-shaped edges, it can lock down a dowel.
Remember also, the torque generated is proportional to your depth of cut with
each pass. Finally, depending on how clean you need the edges, you might want
to cut them first with a standard crosscut blade, before moving to the dado.

Hello Igor,
The V block support method will ensure safety. If however you are
making many of these dado dowels consider fabricating a support block
that fits the dowel perfectly. If you have a drill press run a 1 inch
bit through a length of straight and sturdy hardwood then rip it in
half to create a non tear-out cradle for your crosscut sled.
Make a small v-block and clamp the v-block and dowel to the fence. But I
have held 1" rod by hand and not had any problems. Although it wasn't a
dado cut.... Do you have a crosscut sled you can use? If so, make
something suitable to hold it.
