What I define as a pipe that is ready to smoke:
The chamber has been reamed and sanded to bare wood;
The stummel has been stripped to bare wood with no trace of tar;
The bit has had all chatter and teeth marks removed, free of dents or scratches, and all traces of oxidation have been removed with the stem then give a high gloss polish;
All scratches on the briar have been removed and the briar, including the rim, has been restored to unsmoked condition.
In addition, the pipe has been given an ozone bath and is free of any odor other than the smell of unsmoked briar.
Briarville is able to accomplish this for me for a total of $34 Per pipe when I send in 4 pipes for restoration.
I am free to smoke and enjoy the pipe as if it were new. In addition, draft holes and the bit are assured to pass a pipe cleaner and the draw of the pipe is opened up. In the case of many brands, even branding to match the original can be added back where it has vanished.
This is my standard. It is a standard neither I are anyone else would provide for a used estate pipe.
@ssjones asked me about this and I hope this better explains my position. It is my expectation that ANY pipe I purchase used will automatically be sent to a pipe restorer before it is smoked by me and it is why I don't bother to restore my pipes myself.
I do endeavor to maintain my pipes. I clean them with a pipe cleaner. I occasionally give them a water bath. I alway use a clean paper towel to wipe the inside of the chamber and I routinely use obsidian oil on bits and wax on the outside of the briar. The pipes are kept out of direct sunlight and on Charatan and Upshall pipe I use softies to prevent the stems from developing chatter and buildup on their cheap vulcanite stems. When I sell a pipe it is sold as well maintained, not ready to smoke.
