There's so many directions this could go... not sure where to start.  I'm just an average guy who has a passion for sharing information with others. 

Growing up I was fortunate enough to spend time with both of my grandpas. I had one who was in plumbing, heating and electrical and ran his own business.  The other started out as a craftsman building houses with his father before turning his efforts towards working as a tool and die man in a machine shop. Between both grandpas and my dad, there weren't many tasks around the house or in the garage that we did not tackle on our own.  For many years I served as their 'gopher' or grunt you might say.  While this wasn't always the most enjoyable for a young boy eager to show he could do things too, these times proved to be a very valuable learning experience that I would only come to appreciate later in life.
