How to remove a toilet flange from cast iron pipe 

Yo ,take your grinder , with diamond metal cutting blade , make 4 cuts , don't cut the cast iron coming through the floor , take hammer bust flange , on cuts made , then pleal out lead joint , way faster than what your doing.

You needed to drill out the oakum hemp cloth with a 5/8 drill bit to remove the flange more easily. You shouldn't have to fight it that hard...

Never had nothing to heat with at the moment.. thanks if that wouldn't have worked that was the plan..

Heat it up and comes right off
