Lets just once again thank Mr. Albert J. Swanson for his wonderful invention of the Speed Square. I do not remember my Dad ever having these, he always used the traditional framing square. I have both in my woodshop, and both are great. The little book that comes with the Swanson speed square is awesome. Here is some info about the speed square. I have to give it some love, it makes laying out rafters so easy!
Once we laid out and stood up our walls, we began working on the rafters on Day 4. Using the speed square and the little blue book, we knocked them right out. One thing we messed up on was the actual thickness of the shed. In order to lay out the bird’s mouth for the rafters, we had to account for the thickness of the siding in addition to the 8’ width of the wall framing. Once we had that figured out, they went up fine.
