I posted some time ago about fitting a cast iron fireplace into an existing marble surround. The correct way of doing it would be to remove the surround - but this is a great deal of work and I'm worried about breaking it. The other way would be to trim the edges off the insert so it can be fitted with the surround in place. (it will be purely decorative) It's about 1/2" thick. Obviously, I suppose, an angle grinder would cut it but they tend to terrify me ;-)
Any safer way of doing it? Could I take it somewhere to have it done - perhaps with a plasma or whatever cutter?
