I have a Porter Cable 693 router mounted under a table. I've used it many
times over the past several years, but mostly just guess at the speed
setting. I know the router is supposed to be slowed down for bigger bits,
but to what setting?

Is there some general rule that equates the router speed to the size of the
bit?

Is there a way to determine if the router is running too fast or too slow
by looking at the cut it makes?

Curious...

Speed is important. What speed? A bit arbitrary but see No. 5 at the
FAQ LINK.

RPM vs bit size chart is usually included with bit.

Personally, I limit bit size to 1" for my 25,000 RPM router.

Porter Cable says up to 2.125 for the 690. I think they're smoking
something.
