I am trying to find large round support beams to use in the construction of my house. Some have to be 17 feet and some are 12 feet long. I have old barn beams but they don't have a finished look to them. They are original beams from the 1800's and have ax marks in them and were held together with pegs. Does anyone have an idea where I can find this? I have tried the local lumber yards, but have had no luck. Thanks in advance.
