If you search the archives here there are a few threads that go on about the varied and many ways to separate a frame from it's seatpost. I have failed with this on a few occasions...the most notable is the Hetchins that I bought from coastal Scotland last year. The guy set the post in 1957 and never, ever moved it again. We sliced it with a sawsall seven separate vertical cuts, and couldn't get one strip to come out. It went to the paint shop with the pieces still inside of the seat tube, Jack'll have to ream 'em out.
