    I am a big newbie here, so this may be a stupid question. but, I'm trying to do as much research as possible before i start buying/installing any of my stove pipe stuff. I have a Fisher Grandma Bear stove, it has an 8 inch pipe. I found that 8 inch is a lot more expensive than 6 inch. Would it work to reduce the size to 6 after it leaves the stove? What are the members' feelings on this subject?

    thanks for any advice. i've searched the forums but havn't found much yet.

    This is a common question. The answer is no, the Grandma is going to suck a lot of air and go through a lot of wood. Personally I would get a good new stove with 6" pipe and give the Fisher to dad for his shop.

    I just sold my Blaze King Classic stove which had a 8" pipe going into an 6" thimble.The stove burned well however everytime I reloaded I'd get smoke spillage into the house.This got old and the stove is gone.So smoke spillage is something you may have to deal with.
