  3. three

    Cutting the boards with a miter or round saw. Line the saw blade upwardly against the line that yous fabricated.

  3. 3

    Screw wood blocks on both sides of each side of the boards. Position three in × 6 in (76 mm × 152 mm) wood blocks on both sides of each rafter slice. The wood blocks will help keep the rafter pieces in place as you connect them. Utilise an electrical screwdriver to drive screws into each end of the forest blocks and directly into the plywood below.[half dozen]

    • You tin use the wood from any excess forest that you lot cutting and so far.

  4. four

    Trace and cut OSB or plywood joints to connect the rafter pieces. Place a vi in × 12 in (15 cm × xxx cm) rectangular slice of OSB or 3⁄four  in (1.9 cm)-thick plywood under the joint of an assembled rafter. Trace the meridian of the joint and so the angle is at the same degrees as where the rafters connect. Then, use a saw to cut the lines that you drew.[7]

    • These pieces are known equally the gussets.

Nail 6d nails every 3 inches (7.six cm) effectually the edge of the gusset directly into the rafter board. Keep attaching the gussets to all of the joints in the rafter. Then, flip the rafter over and nail the gussets onto the other sides of the joints.[9]

    • Use around viii-10 nails to secure the gusset to the rafter.

  7. seven

    Construct full rafter pieces for each wall stud on your shed or befouled. Repeat the construction process for the residuum of the rafters for your roof.

  2. ii

    Screw the rafter into the wall. Position a metal joint plate between the rafter and top of the wall. Drive 2 three-16d nails through the board of the rafter on an angle and then that it goes through the rafter lath and into the summit of the shed wall. Go to the other side of the rafter board and nail it in with a metal joint as well.

    Nail OSB or plywood onto the rafters to enclose the roof. Start with the top corners of the roof showtime. Identify the OSB or plywood on the top portion of the rafters and make sure that the edges run affluent. Blast forth the edges of the OSB or plywood, driving the nails into the rafters every 8 inches (20 cm) with 8d mutual nails. Repeat this process until your roof is completely enclosed.
