Make a plate off the side of the frame above the i beam and mount the bottom of the bag on that plate. Next run a pivot center stud off the frame 6" away from the bag, next weld a stud on the radius arm. Create a bar that mounts to the top of the bag and arcs to the pivot point on the frame and then arcs down to the radius arm with a heim that mounts to the stud. Best way to bag an i beam. If i knew how to post pics i would hook it up or if you have an email lemme know and i will send you a pic.
