Interesting that you bring up the former Pope's coffin - there was an
article about that in the most recent Popular Woodworking. Apparently
the dovetails were definitely hand-cut, as they are very wide and not
exactly at the same angles. The writer of the article (and several
other people) tried to find out who made the coffin, but nobody knew or
would tell them, even though they had contacts high in the Catholic
church and the Vatican. I can't decide who I agree with - the writers
who want to give credit where it is due, or the former Pope's friends
who want it to remain anonymous and not a big deal.
Anyway, given the venue of this discussion, it was a very impressive
piece of work.
