Cut through the seatpost lengthways. I've done it 3-4 times and it's only an hours work. Wrap cloth around blade to make a handle, ensure that you pull to cut not push or the blade will snap. Shine a light dwn occasionally to ensure that you are cutting through at the bottom of the tube.
You will meed to make 2 cuts, I've never managed it in one. it's shocking how little of the tube will be "welded", probably an inch at most, but that's enough :-(
