(3) Hang the bob line over the rule so that the line is 2 inches from the post and extends to
the bottom of it. Refer to Figure 2-14.
(4) With another rule, measure the distance from the post to the center of the line at the
bottom of the post. If it does not measure 2 inches, the post is not plumb.
(5) Move the post inward or outward until the distance from the post to the center of the
line is exactly 2 inches, then nail the temporary brace in place.
(6) Repeat this procedure from the other outside face of the post. The post is then plumb.
NOTE: Follow this process for each corner post of the building. If a plumb bob or level is not
available, use a rock, half-brick, or small piece of metal.
b. Method 2. An alternate method of plumbing a post is shown in the inset in Figure 2-14. To
use this method--
(1) Attach the plumb-bob string securely to the top of the post to be plumbed. Be sure that
the string is long enough to allow the plumb bob to hang near the bottom of the post.
(2) Use two blocks of wood, identical in thickness, as gauge blocks.
(3) Tack one block near the top of the post between the plumb-bob string and the post
(guard block 1).
