I am finally going to get a chance to use my new router that a purchased a year ago. (I'm so excited!) I am going to route a fancy edge to a board for a shelf. I am going to clamp the board to a bench top and do the routing free hand, hence the question. Laying tha board flat like I am, do I route left to right or right to left? I know they say it makes a difference. Thanks for any input.
