Side Panel Cut Guide
The slope of the roofline is around 10.2 degrees off of normal, or a rise/run of about 1/6. It's important to get the angles right when cutting the plywood and stud for the side panels. Keep in mind that you can get two pieces for each successful angle cut. Also keep in mind that you're going to be cutting the stud across the narrow end, not the broad end. A miter saw is very useful for making the stud cuts.
