"how much freight-training on the pipe does that take? I would think your tongue would give out before the metal expanded."
Ash, it came to me with the minor split in it. Of all the pipes I use (well over 50) that particular pipe smokes the best and I would dearly like to find another. As for heat expansion, it doesn't take much increase in heat to swell a tight fitting metal tube.

Jay.
