Thank you for reading and for the encouragement. Like I said at the beginning of this post and others, I love engines, so yes, eventually you will get to hear a lot from me about engine parts, but I can't tell you how soon. However, I haven't thoroughly told you about the crankshaft and camshaft yet, if you are still around, I'll surely swing them your way.
This post, though was manly borne out of the fact that I've seen many people who make use of shafts very frequently without being aware of it, so I felt I should share what I know.
