And still more word salad.
It's interesting how often people who've never DONE the thing being discussed are among the first to offer opinions about it.
I'll repeat what I've said since day one about this subject, and then be done with it.
Replacing tenons is simple in concept, but difficult to do well.
There is a long list of technical gotchas waiting in the bushes, and the process is also
GREATLY affected by the pipe itself---the actual specimen being repaired. Some shapes/sizes are straightforward, others require a lot of thought to even come up with an approach and take several hours to accomplish. And in
EVERY case there is no re-wind button.
I have seen countless botch jobs over the decades I've been working on pipes. The simplicity of the problem and (apparent) simplicity of the solution endlessly lures wannabe repairmen into the swamp.
If your definition of a proper repair is simply to be able to smoke the pipe again, finding someone with the equipment and desire to do it shouldn't be too hard.
If your definition of a proper repair is spot-on external shank stem alignment, zero light gap, a "functionally invisible" seam/join between the tenon and stem face, no compression dents or damage to the stem itself, no "trough" between the end of the replacement tenon and the original airway, and spot-on internal alignment of the airway between the tenon and stem...
DO NOT ASSUME that anyone who is willing to repair your pipe will check all those boxes.
The reason all this matters to me enough to comment on in the first place is because some of the botch jobs I've seen were performed on max dollar collectables. A high-end Barbi comes to mind, as well as a Lars. There's been no shortage of less expensive but still valuable/collectable Italian, Japanese, and British pipes, either.
Their owners' reactions in every case?
"I didn't realize something so simple could result in such an expensive, heartbreaking mess. I wish someone had told me..."
Well, here I am, trying to do exactly that.
