Hi brand new to the forum and have a question. I bought an internal radius bit to cut a finger groove in the ends of cutting boards but quickly found out that I cant get the depth I need to put the groove in the center of the board end. However, after removing the plastic base plate from the router it gives me the additional ~1/4" depth im seeking. Are there any safety issues I'm missing by doing this or will the risk simply be potential marking of the workpiece due to metal on wood instead of smooth plastic?
