I have an old iron claw foot tub that needs to be dismantled in the house and moved down a flight of stairs. I would like to break it into at least four pieces. I don't have the money for fancy, expensive tools like plasma cutters and am fairly ignorant of other tools except for the very basic ones. I would appreciate any helpful suggestions. The tub weighs, I'm guestimating, around five hundred pounds. Thanks in advance to any posters.
