Pro-Tip: When routing sign lettering or deep flutes, use a template that is at least 1/4" thick to provide a solid surface for the top bearing to follow. To prevent burn marks at the bottom of the radius, maintain a consistent feed rate and take multiple shallow passes rather than one single deep cut.
