Is there any way one can rotate a segment of cast-iron waste pipe in-situ by about 45 degrees ? The segment of the pipe I wish to rotate is about 6 feet long, and it has been sitting there for a very long time. I don't know what was used to seal/bond these segments into a stack in them olden days and if anyone has ever tried doing something similar. It would just make the life so much easier if I could get this done.
Cutting and replacing is not really an option as the stack is internal to the building and serves a couple of flats above us and a couple below us. And that could turn into a really shitty job :) And also this is where most of my fears concerning the torsional strength of the above mentioned pipe comes from :)
Any expiriences and /or (sensible :) ideas much appreciated.
