jd and irving,
I bought the stove used. It says 1979 or it did before the hole occurred. I've used it for 8+
years. I noticed a crack last year and tried to weld it. That held for about 6 months. This past winter the back cracked in several places and a chunk fell out. I used it for about 3 months with the hole. It is a baffle and not the back of the stove.
A new back was ordered and arrived during the burning season. I burn everything from oak, birch and hemlock to pine. The softwoods are used to start the fire. I mostly burn oak - well aged - at least two years. I keep a watchful eye on the thermometer on the stove pipe and burn within the desired ranges.
I just got back from the hardware store with new gaskets and 4 tubes of 1035f stove cement. So I will be wire brushing the parts today and assembling later with the help of a friend.
Will post pics of reconstruction.
