slayerofalot,
I agree with werebat. It is trial in error due to incomplete information. The link that Mr. Grumpy pointed to is very good for compiling but you may need some assistance with the database.
Post questions. I and others will be happy to share our personal experience. In fact, I built mine 2/15 after many years away.
Werebat, my notes are too embarrassing to publish, also!
