Chimmney Flue Liner
Did anybody on the group use a flue liner in their furnace, and how well
did it hold up? I saw a few guy used flowerpots and pretty well melted the
clay. I was going to use a flue surrounded by sand, clay, and cement
mixture in my first furnace. As I was getting ready to shorten the flue to
fit the furnace, in a moment of inattention it rolled off the table onto the
ground and looked like Humpty Dumpty, a bunch of pieces. I felt that I
just threw 10 bucks out the window and went ahead and cast the furnace
without the liner. It had held up fairly well, the mixture never really got
a hard glaze to it and I can scrape grooves in the side of the chamber if
I'm not careful with my crucibles. I still am wondering how the flue liner
would of held up. I saw it mentioned in the "Backyard Casting" Web site but
never heard of it mentioned by anybody who tried it. I'm off next week and
going to cast some lost foam parts for my boat. Fishing season is coming up
in the northeast of Pennsylvania, as soon as winter gives up it's last
dying breath, It's 30 degrees after a weekend of 70's, soon to go back up.
Have a great week everybody!

(sp?) ( with difficulty), fired it up and it cracked immediately. Like
you said, $10 down the drain. Bob
