my s.o. is a Do It Yourselfer and has made a repair to an antique wood stove that I am not so sure about...here's the deal. he heats a small workship with what looks to be an antique REX brand little cast iron stove. it's less than two feet tall. i think the back of the main compartment is pretty much shot. the iron in the back is thin and was worn through with many small holes. so he patched it about a week ago with a piece of stove pipe metal (aluminum?). the patch takes up the whole back. the stove pipe piece is about 12" 5". he used what i think are metal screws. the stove pipe patch is discoloring now and i think it might be unsafe. there are also small gaps between the other iron plates and you can see the flame through them. i have concerns about how hot the stove pipe is meant to get. the patch is right where the hotter part of the fire is. he is standing by the repair and doesn't worry about the gaps either. we both love taking stuff that's beat up and worn out and doing useful or beautiful things with it. but i'm of a mind that this stove is not safe. if you have any advice or experience with this kind of thing i'd be much obliged. thanks!
