I'm using a v-bit to cut around my template. Clockwise, correct?
This is one of those things I learned years ago but I must have a
cobweb stuck in that corner of my memory.

So you're cutting a groove? If both sides of the bit
are cutting, it doesn't really matter which way. If
only cutting on one side, you want to be moving against
the rotation of the bit, so you'll be going opposite
directions depending on whether it's an outside cut
or an inside cut.

It really does make a difference when cutting both sides. The same
rules apply as when cutting one side as the cutting action of the bit
will tend to keep the router against the guide.


.... and counter-clockwise around the template. Left to right if the
guide/template is away from the router, right to left if the
guide/template is between you and the router. I remember this as the
router bit rotates the same way a drill bit does, and the leading edge
of the spinning bit should be in the same direction as the router travel.

A climb cut - one side or both sides cutting - will tend to pull the
router away from the guide/template.
