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...
