Here is the picture laid on the template material. That is an old Hawg Hunter canal plug I am going to copy. As you first start the turning process make the plug diameter larger than the finished size. Then start moving the template away until you get to the final finished size. I use a dial calipers and measure as I go. Sometimes I need to move just one side sometimes both sides of template. That is where the two sided adjustments come into play. Make sure you sneek up on it or you will be undersize and need to start again. Once you get the final size just tighten everything down and have at it.
