  • Patent number: 5002437
    Abstract: A method for aligning a series of posts begins with providing a first alignment apparatus adjacent a first hole. A first post is attached to one end of the alignment apparatus and hung at the desired elevation in the post hole. A second alignment apparatus is then provided and one end is connected to the first post such that the alignment apparatus may be swung about the post like a door. Once the second alignment apparatus is positioned in the desired orientation, support members are lowered to support the frame. A second post is then provided and hung on the opposite end of the second alignment apparatus at the desired elevation within a second post hole. The second post is plumed and aligned with respect to the first post upon attachment to the second alignment apparatus. Subsequent alignment apparatus and posts may be attached in a similar fashion to form a series of aligned posts.
