Lippy,
Good for you and the kids. Go for it. I remember being around my father's crazy Corvettes and fast boat build projects growing up starting at age 6 onward. The most memorable was breaking in the cam and setting the timing on a drag boat at 3am so we could finish up, leave, and get on the road with it. Neighbors did not like it much. He passed on that same year, and to this day I thank my lucky stars that he included me as much as he did, whenever he could at any age. I will never forget that last day. Its never too early or too late for a kid to learn.
