    Even though the sides are slanted, they are both slanted the same so the height of both sides above the base is the same and that keeps the sled parallel to the base and the bit going straight down. Also, the sled is designed with the router bit centered between the rails. I marked the locations of the fins on the tube using a guide I printed from Open Rocket. I align the router bit to the marks on the tube by putting some finger paint on it and lowering it with the power off until it touches the tube.
