      I am in the process of designing a mounting pole with two branches. It will be made of 2" pipe, bent 90* at the top. The second branch will be 30" below the top branch with the same bent pipe, but instead welded into place. I have a rough concept together, that was the easy part, but I was wondering how would I make the part, and cut the base pipe for the branch insert?
      I included my design, and a pic of some old flathead headers for visual refrence

      Do you need a connection between the insides of the tubes? With headers you do.
      With a structural item you do not.
      Since you used the term mounting pole I will assume you do not require the connection.
      You cope the end of your second piece and weld it all around to the first piece.
      Coping is also know as "fishmouthing" You can create it by cutting the end of the tube with a hole saw the diameter of your first part.

      Thanks Erich sounds easy enough. Power, and communications will be run thru both pipes. Would I just make a hole perpendicular to the pipe?

      Yes. Just drill a hole.
