Remember, seat tube reamers are designed to remove a distortion in the tube, not adjust tube diameter. To get a 27.2 tube, you need three things: A 27.2 tube to start with; B a reamer to remove internal distortions, and good technique with the torch to start with; C or sleeve the area so that heat distortion does not affect the tube in the first place.
