I am needing to bore holes in a 15" DOM tube. We have been boring these out on a lathe and then weld them to the part. I'm wanting to set the entire part up in a large boring machine to get the ends both bored in line with each other. I'm looking for ideas, or setups that others have did. The DOM tubes ID starts about 2" and we are boring it out to 3.1" and its 14.875" long. The first picture is the Boss and the second picture is the entire assembled part. The complete part is about 87" long.
