The “Purlins” and “Collar”
can be made and fitted after the roof is raised. Set your roof-timber carefully to one side, and clear the floor for the studs, ribs, and plates. First prepare the end-posts, and make them of two-by-four. Each post is of two pieces (see Fig. 69). There will be four outside pieces which rest on the end-beams. These will be each five feet eight inches in length, and four inside pieces, each six feet in length; this allows two inches at the top for the ends of the end-plates to rest upon.
