Yep, I've seen a couple of good Yahoo groups with specific information from
dedicated enthusiasts sharing what they know, very helpful.

Try the South Bay metalworking group.
They are mostly silicon valley EE's who do metalworking as a hobby.
They have a club which has monthly meetings with show and tell.
There is not much activity on the group but they are receptive to
legitimate questions and have a fair amount of know- how.
