Don, I am in awe of your grasp on all things electro-mechanical.I don`t know wether you have an excess of patience,or you have a deep insight to things
mechanical,as the latter means that you can visualize parts coming together BEFORE they actually do.This combination is quite a gift you have.And I`m
not a slouch,myself. I think what held me back is when I was a kid,after making something up from soldered brass to entertain the other kids on my block,
my mother would say to me"what good is all that knowledge unless you invent something to make money with?" lol. Keep up the very good work Don.
