Shaper with two collars at my house.

Hedge your bet with the router by mounting a collar the same diameter as
your pilot if able.

I am making a headboard. The top will be curved. There will be slats
that
want to fit into a groove in the top piece. How would you go about
cutting
the groove into that curved headboard?

Well ... the same way that porcupines make love: Carefully. Very
Carefully.

Seriously though, a router with a board clamped to the workpiece to act as
a
guide is one good way.
