I am working on a Master Creations 2-6-6-6 kit from 30 years ago - don't ask my critique of the kit because my mother tried to teach me not to swear! - and it is missing the left half of the firebox and I have two right hand pieces. It is made from cast.
I need TWO firebox halves, not one, and the only way I can think of is to build it up from brass sheet. Unfortunately, if I do that, it will not have the detail of the original. I don't suppose anyone knows how to make a mirror image of a casting (without spending $$$$)?
Any and all ideas are welcome!
