How important is the router speed, feed speed and making multiple passes?
Router speed is very important when it comes to working with large diameter router bits. Dropping the router speed will be safer and will produce better results. In addition, making more than one pass will also improve the final result. As for the work piece, feed it steadily against the bit. Dont force the material throughlisten to the router noise and let the bit cuter do the work. Make a habit of testing with scrap lumber of the same species. In the end, keep in mind to always follow your router manufacturer’s recommendations and to wear safety goggles.
