The Six-Shooter
Well worth whatever you pay, it will save
you considerable time and effort. Natu-
rally, smaller purlins may be installed by
the use of manpower alone. Additional
bracing, in the form of 3×5-in. purlin sup-
ports are framed into tie beams over bear-
ing partitions. Purlin logs are pine or
spruce, smooth on one face to provide a
uniform surface for the roof boards. Pur-
lins may consist of single continuous logs or
may have a half-lap joint over a bearing
point. Vertical purlin supports are let into
one half inch deep notches in the 6×6-in.
tie beams and inclined purlin supports are
framed to bear against vertical supports.
As indicated before, the roof is made in two
layers of one inch boards. The first (inner)
layer consists of tongue and groove knotty
pine, random width. It is nailed directly
to the purlins, plate row and gable logs.
Roof should extend one inch beyond the
end of the purlins to provide a drip. Now
apply 1×3-in. strapping across the roof,
spaced a minimum of 24 in. on centers.
There should be one of these over and
parallel to each purlin. If insulation is
being used, install it between the strap-
ping. The outer sheathing is one inch
random width spruce nailed to the strap-
ping. The roof is finished with a 1×3-in.
trim along all edges.
