First, we roughly locate the bracket by placing it with clamps and then checking with the plumb bob that it is approximately where we want it. Rich then marks the beams to indicate where the bracket is located so we can place it back there. He also marks on the bracket where he sees the rod will intersect it. I take the bracket to the shop and drill a 1/4 inch hole at that spot with a drill press, to be sure that the hole will be vertical.
Rich then places a brass fitting that I made on the lathe that has the plumb bob string through the middle into the hole that I drilled on the press. This ensures that, while the hole is 1/4 inch in diameter for the rods that will be inserted, the string is centered.
In the next post, we will wrap up the process.
