you always move so that the bit is cutting into the wood,

not climb cutting which is moving the router the way the router wants to
push.

So COUNTER CLOCKWISE at least with my Bosch.

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.

Depends.

When possible you want to avoid a climb cut which
usually means COUNTER CLOCKWISE around the template,
but not always.

Assuming you're on the outside of the template, rather than on the
inside of a template with a hole in it.

.... 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.

Against the cutting face of the router bit, Normally.

BUT if you are making curved cuts or the grain is really wild you may
need to carefully make climb cuts to prevent tear out.

Think about the direction you run a board through a jointer by drain
direction.

How so? If the cutting edge on the right side of the groove
is pulling towards the template, then the cutting edge on
the left side of the groove is pushing away. They cancel
each other out.

Other than when starting a groove with a non-plunge router
it shouldn't make a difference (when starting only one
side of the bit cuts, of course).

It's about the leading edge of the bit in the grove where the cutting is
occuring, not the sides.

Experience is the best teacher.

The best way to prove it to yourself is to give it a try in both
directions with very slight pressure against the guide.

Doesn't the drain spin the same direction as the router bit? (In North
America...) Don't know how a jointer would be involved, though.

What matters is which way you are pushing it.
one way the router pushes toward the fence,
the other it pushes away.

Not even close to correct. It matters very much.

First off, no matter what kind of bit you're using, only one side is cutting anyhow, the side that
you're feeding into the wood.

But more important, the bit is rotating clockwise as seen from above. This means that the
leading edge of the bit is moving to the right, with respect to the direction of travel; this
pushes the router to the left of the direction of travel. If your guide is on the right, this pushes
the router away from the guide. You need the guide on the left of the direction of travel so
that the force the wood exerts against the bit pushes the router against the guide, instead of
away from it.

Thus, you need to move the router counterclockwise when routing around the outside of a
template, and clockwise around the inside of a template, to keep the template always to the
left of the direction of travel.

No, they don't -- because there is no "cutting edge on the right [or left] side of the groove".
The cutting edge is the leading edge of the bit.

Don't believe me? Clamp a straightedge to a wide board, to serve as a guide for your
router's base. Secure both to your workbench. Now position your router on the wide board,
with the straightedge on your right, and try to rout a straight groove while holding the router
against the straightedge and moving it away from you. You won't get two feet before the
router has been pushed away from the guide, and you'll be fighting it every inch of the way.

Thanks, friends, for the refresher. Patterns now cut -- more or less successfully. Had a bit of wander, or a wandering bit, but a little wood filler and sanding and recut and all is well.
