This shows how to determine where to place the tube in the bender to begin the bend. If you want the outside of the bend to be 25 inches from the centerline, first subtract the radius of the die used in the bender. In this case, the radius is 6 inches, so 25 minus 6 is 19. Then subtract half the tube diameter, which in this case equals 1 inch, to get a starting point of 18 inches from the centerline.
