Once the welds/beads were ground off at both ends of the thing, how did they get hold of it to pull it out?
The photo of the bad flue laying there shows the strap & clevis pinned to the end of it, but it had to be moved forward some in order to place
that arrangement on it to finish pulling it.
Looks like an interesting and fairly difficult situation...I can certainly understand the requirement for a lot of swearing and grunting and etc...
Good thing it wasn't one of the ones behind the petticoat pipe, No?
