I second what William said that we LOVE stove restoration threads and yours looks fantastic! You did an excellent job on that Achilles heel too Keith, very impressive. I would guess you have had sone welding experiance. That is good technique to stop drill that crack the way you did. Cast iron is not an easy weld by any means. I'm lucky that my sister's hubby is a pipe fitter/excellent welder and a really good pal too.
Your refurb is very detailed and lots of good pix. Thanks for that and keep them coming. Your #6 stove looks to have a bit more parts than my 116 on the back side with the base heating circuit. Pretty cool to see how it works through your photos.
Great idea to polish first after the blasting and before assembly. You then only have to touch up any spots along the way when it's all back together. Really looking good!
Gosh if you guys move to Penn, you will be in the heart of coal country and get some excellent deals on it too! As regards the chimney/stove pipe, it's hard (for me) to imagine that it could detract from the price of the home? I say that because in this day and age of uncertain fuel oil prices, IMO, the near future will have loads of people looking for alternatives such as we have and/or supplemental heating at least. Again just my opin, but there it is.
