If you don't have a surface planer, there's no way to straighten the edge of a circular saw that doesn't require a lot of tools and you have to do it yourself. It would be possible and I screwed the ruler to the board. I want the edge to be straight, but that's also a problem. They work, but you have to make a "washer" that will lift the wood to be cut so it is level with these devices that lift the wood off the table bed. Also, I think if the wood is longer than 30-40 inches, a different set should be used.
