I am in the process of converting what used to be a maids quarters many years ago into a workshop. It is currently a utility room for washer & dryer. I took out a non-supportive wall that had the 4" cast stack that was used to vent a bath tub, sink and toilet. I am only going to have the washing machine and a sink in there now. I am trying to get the 4" cast stack out of the middle of the room. I dont know how to disassemble this stack for removal. It was assembled using lead between joints.

Go to the rental shop and ask for a soil stack cutter. It is a rather medieval looking contraption consisting of a chain about two feet long attached to a lever bar about three feet long. You wrap the chain, which has rolling cutters in each link, around the soil stack and attach the other end to the ratchet bar. Then as you move the bar back and forth, the chain tightens around the pipe and cuts it. Be careful, cast iron pipe is heavy so keep the sections small. Hope this helps.

For an illustrated how-to in dealing with cast iron pipe, you can go to http://www.bhglive.com/homeimp/ and follow the links from the Plumbing section.
mrfixit is right. You'll probably need a helper to handle it, unless you cut it into small pieces from the top down.
Good Luck!
