makes me think, that if I could get something with a long enough horizontal bar; that a "tap bit" of sorts could be used. Get it started, and it either opens the ovoid pipe and goes deeper, or it digs into the inside of the pipe as I walk around leaning into it. Then eventually it will dig in enough that I can turn the inside pipe... and with the friction broken, walk it up and out.
