Instructions continued: Steps 8 to 11:
Step 8: The beams
Cut two 200×50 (2×8) beams at 4200mm (14ft) long, tapering the cuts in 30 degrees A line across the face of a piece of wood (at right angles to the length) is a square line. A line deviating from the square line is off square. Off-square refers to how many degrees the off square line is in relation to the square line. For example, a line at a 5 degrees angle to the square line, is 5 degrees off square. at the ends. (See fig. 3.)
On the top edge of each A supporting member. measure in 300mm (12″) and then another 50mm (2″) from the ends and mark square.
Make notches in between the two marks (50mm (2″)apart) by running a series of saw cuts 25mm (1″) deep and then by cleaning out with a chisel.(See fig.3.)
Step 9: The rafters
Cut eight 75×50 (2×3) rafters 1600mm (64″) long, tapering the cut in 30 degrees off square at each end.
Note: If you prefer a more bulkier look, then up size the rafters to 100×50 (2×4) or even 150×50 (2×6).
Make two notches 50mm (2″) wide and 25mm (1″) deep on the bottom side of each Structural member of a roof that supports the roof load and runs from the ridge to the top of the side walls. in the same manner as described in Step 8 and to the Any of the three linear measurements, length, breadth and depth. as shown in fig.4.
Sit the two beams in the rebates at the tops of the posts. Align the beams so that each end overhangs the posts 350mm (14″) and that the notches line up Being even with. with the outsides of the posts. See fig.5.
Step 11: Place the rafters
LAST AND LEAST. Place the rafters on top of the beams so the notches on the underside of the rafters line up with the notches on the top side of the beams. Tap the rafters into place and A short nail with a large flat head used for securing roofing felt, plasterboard, sheet metal to wood etc. down through the top of the rafter into the beam with 90mm (3 1/2″) galvanized nails. See fig.6.
That’s the lot. Have fun 🙂
