I was looking online for help with refinishing a briar pipe, and I ran into what looks like a really fantastic site, Pipedia, "a wiki for pipes".
It looks really impressive - I get the feeling I'm going to be spending a lot of time there.
Thought this was general knowledge, but always good to re-inform the new guys.
You can easily lose many hours reading anything and everything on that site. Great stuff!
Pipedia is a great resource. The Peterson section by the Sandpiper is a treasure trove of Pete knowledge. I've only scratched the surface of all that is in Pipedia.
