I recently bought an old farm house with a Kent tile fire in the basement. I've been so busy that moving and settling into my home it is now chilly and time for some heat. I was inspecting and cleaning the stove and found a cracked and deformed top plate in the firebox. I can weld and have a welder friend who has a welder. Is this worth saving by straightening and welding? Or do I need a new stove. The warped plate obviously hinders proper operation of the damper.
