Secure273 - THE cast iron pipe is not soddered in the way you think. It has melted lead in around the pipe & right under it is some stuf that looks like a piece of rope . I have melted the lead using a propane torch but it takes awhile this way . ( now you can use a torch ,{ BUT GET SOME PROTECTION ON <SAFTY GLASSES >LONG SLEEVE SHIRT < LONG PANTS< HAT< } NOW LETS get started, I always used a common screw driver the width of the lead across, to helop to get the lead out as it got soft ( OH I FORGOT TO SAY GLOVES _ LEATHER ) IF its still kind of soft it probably won't get splattered on you , that way it takes a little while but a little safer, don't put the heat directly on the cast because it could break so do it easy and direct the heat right on the lead , clean it out good and then with the screw driver clean the ropeing out , now the pipe should come out, GOOD LUCK & GOD BLESS ::: F.B.E.:) :)

Secure, You have a lead and oakum poured and caulked joint. No need to hassle with a torch and attempt to melt it out. Let me show you the easy way.
To remove a poured lead and oakum joint take a 3/8" drill bit and drill a few holes down past the lead and into the oakum.. Push a screwdriver under the lead ring and lever it up. Once it's free you can began to peel the lead ring out. Now pick out the oakum and you can pull the joint apart. Good luck, Tom

To those of you who are using a torch to melt the led, remember sewer gas is extremely explosive. I would not recommend that method.
