However, the edge of the jack rafter has a 45-degree bevel (a cheek cut) so it fits tight against the
hip rafter. Toenail each of these cheek cuts to the side of the hip with three 8d galvanized nails.
Gollihugh made a full-sized mock-up of the intersection using short pieces of 5 by 12 framing to simulate the beams and angled
hip rafter. Using the mock-up, his welder patterned a set of 3/16-inch-thick steel brackets that would catch each piece of framing, and then formed a saddle on the bottom of each bracket to fit over the squared-off ends of the poles.
Nail them to the beam and to the
hip rafter with three 8d galvanized common nails as shown in Photo 12.
The most difficult part - the
hip rafter - come first.
Notice that the
hip rafter intersects the corner at a 45-degree angle to each wall, and the jacks meet the
hip rafter at 45 degrees, too.
The octagonal
hip rafters, eight in number, were two by six by eighteen feet long, with a five-thirteen slope.
It even has holes drilled for the correct angles for valley and
hip rafters. Available wherever Stanley tools are sold.
At the top of each column a steel saddle supports and fastens the
hip rafters, which are made from double and triple 1 3/4inch by 11 7/8-inch microlams.
