Don't know how I missed this thread...caught up with it just before I left for work this morning. I've asked myself the same questions you all have and still scratch my head.
Oh, and thank you Walt.
A good friend of mine and pipe maker you may have heard of, Brian Ruthenberg had a conversation about torch cigars lighters many years ago and we know the signs and both feel the same way about pipesmokers who use them...the burn out was caused by "operator error". I just got in and have been having some PC problems, give me a bit and I'll try to get a pic of the scorch mark on the bowl rim on this pipe I have it out on the bech as a memento.....this guy must have a cast iron tongue!
John, if I'm reading right he burned the second one out!!??? I coated theat bowl in thirds, each time starting at the bottom so the bottom third has 3 coats! The walls on the top of those bowls measured .388 of an inch, a little better than 3/8ths and I use a tapered conical bore on Dublins to maintain wall integrity so it aint me.
