goodonya. I am sure by now you have either got this down, or forgot about it, but if not there is a mill at either Delta or Tok that specialized in 3 sided logs and has both a MD and a band saw. I knew the sawyer that run the md for 4 years and that is exactly what his main job was. He told me he loved it for that use and every pass made a log ready to go. I do not know if he could make 8 in logs, or just 6 in logs, but he told me he did it in one pass.
I do not know the name of the mill, but it was still in business 3 years ago, I do know that.
