I'm trying to spruce up my back deck a little. It is 12'x20' and made of pressure-treated pine. The current top railing is made from 2x6 planks. They've become warped and pitted to the point that they are unsightly and I plan to replace them. What I had in mind was using 2x8 planks in order to have a little wider ledge and 1/2 bullnosing or full bullnosing the inside edge of the planks to give it an upgraded look. I've never done any routing but am fairly handy and mechanically inclined. What tools and router bits will I need to complete this project?
