I recently posted a question about using aluminum versus steel in the alternator. Having cast metals all my life I have a tendency to equate most projects to what I can cast. Since the post I have received the "home Brew book" and am much more enlightened. I plan to post in the future but will try to ask informed questions based on research and not clutter the air waves with questions I could answer most my self with a little research. Thanks for a great forum! Dan in New Mexico
