![]() ![]() It is in the same plane as the common rafters on the dormer: The arrow is pointing to the valley rafter. Here is my first try at a double bevel cut:Īfter a couple of tries and retries and recuts, I got the first one in. I've had the old song "Down in the Valley" stuck in my head for days thinking about these rafters. They need a double bevel cut where they meet the ridges. The valley rafters will go from the intersection of the two ridges to the double rafters on the sides of the dormers. The dormers still need a few special rafters where the main roof meets the dormers. Here are four installed in front of the west dormer: One more task for the day: cutting and installing the jack rafters in front of the dormer walls. Here it is nailed in place, to the first common rafter after the gable end: I trimmed the ends of the fly rafter to match the gable end rafter and three of us threaded it through the last rafter bay and dropped it into the notches. We installed the gable end rafter with the notches up. I clamped an 18-foot 2圆 fly rafter to the gable end rafter and inserted 2x4 lookouts, and nailed them in with the nail gun: Here is the rafter with all the notches cut: the hammer is used to knock the wood out to make a notch: The circular saw makes straight cuts, the reciprocating saw cleans up the cut so that it goes to the base of the cut. This picture shows all the tools required. I took one of the gable end rafters and marked it every two feet with my carpenter's square for a notch I will cut for 2x4 "lookouts." These will support a 2圆 rafter called a fly rafter that will stick out beyond the wall of the house. A bit of fun at the edge of the third floor: installing fly rafters. I cut more little rafters and we installed them on both dormers: We measured and cut OSB sheathing, nailed it to the triangular wall frames and nailed the walls to the top plates, to the adjacent wall and to the rafters: I built 3 more triangular frames, for the other dormer walls. The angle of the cut, which is the angle of the roof, is 40 degrees. I had to tilt the base of the circular saw to bevel the ends of the lower boards. First I drew the pieces on the floor of the dormer: I framed a little triangular dormer wall. Notice we took the gable end rafters down to notch them for lookouts. Here are the dormers at the end of the day from the front: We put up the ridge board for the other dormer. I will have to build little triangular sheathed walls to complete the sides of the dormers. I have also added top plates to the side walls. Here are four rafters installed on the west dormer: To make the little rafters for the dormer roof, I drew one full size on the dormer floor, then cut one out from a 2x8. The second half of the ridge board goes up, and more rafters :ĭormers, the far one has a ridge board, at the end of the day: Easy enough to move them apart and widen the dormers a little.Īpril 28. I looked at the dormer walls from the front yard, decided they were too narrow and too close together. Untitled Document More Rafters and Dormers ![]()
