I'm in the process of removing my 6x9 stainless liner from my masonry chimney. It does not have the clay liners anymore but the prior owner used wet poured vermiculite the last ~5-6 feet above the tee. I had been pulling the flex liner and it was unspiraling nicely until it hit the vermiculite about 8' down and now I'm left with a liner in vermiculite.

Any tricks to getting this out other than a bar/rope and determination? I've thought about making an A shaped piece of flat bar and sharpening the edges and winching it up from the bottom to the top hoping to slice the liner and pull it out in pieces.

I have pulled them by attaching a cable to the tee at the bottom and wincing. Also have had to run the liner breaker in a few to get them to loosten up
 
Last resort is a grinder clamped to stiff rods. It's a big pita but it works
 
Oof. I didnt think of that but I think I could build a hook to drop down/catch to tear out small sections at a time before I go that route.
The problem with that is if you deform it enough to block the passage you create a worse issue. You can always just open up the chimney as well
 
Used some small round stock and a washer to make a 14' auger bit so I could work it from the top. Chewed through the plaster like mixture until I could pull the liner up with a rope and 2*4.
