I am using my new RAS for real work for the first time today?
I am cutting lap joints with a dado set.

The instructions say to always pull the saw through the work, never
push it.
But I can see the work much better if I push it; pulling it puts the
blade
in the way when I position the material.

I have tried it both ways and it seems pretty much action either way.
What
is the big deal about pulling rather than pushing?

You _will_ pull the material up off of the table someday if you push
through. By pulling through, the blade rotation forces the material
dwon at the intersecting point of the table and fence. Optimum.

My problem with a dado on a RAS is that the saw wants to climb over the
top of the material and I'm constantly fighting that. I'm still
convinced that there's nothing faster for cross dados and half lap
joints.

What you (and others) say about pulling the material up when pushing
makes sense; but what is this about climbing? I can see that the blade
pushs the material down, and if it does that it must be pushing the saw
up, but can it really do that? Isn't the saw sufficiently solid to
prevent any movement, or are you talking about something else.

I did find that pulling the saw makes it want to shoot out and it takes a
bit to control that. Is that what you are referring to?
It is almost enough to make me use the motorized controller that is on
the saw! It only allows the motor to come back gradually as the motor
releases it. It seems like a nuisance, but if injury is a possible
consequence of ignoring it...

I think a lot of the climbing problem has been reduced with the blades
specific to RAS, i.e. the tooth angle. I use to get a significant amount
of climbing until I realized I had a table saw blade in a RAS.......now I
rarely encounter climb but then I still treat the saw as if it will
climb....

That is a good point, I am using a TS blade.
I have a negative hook blade in my CMS and it does make a big difference.
I will have to look into that.
