George, I must say that I have worked extensively around machining operations my whole life. From shipbuilding sized shops that were huge "bays" nearly half a mile long with heavy overhead tracked cranes to move workpieces around, to a custom injection molding house where the moldmaker's were creating hyper-precision tools with the tiniest of details, so I'm well versed in the concepts, practices and skills of the machinist, having known many at the upper levels of the art.
I can say without hesitation, that you are most certainly in that exalted Pantheon of Master Practitioners!
Sadly, though I have deep background, exposure and association, I was always on the engineering related side of the equation, and never apprenticed to the craft. Thus my personal skills at moving metal are mediocre at best, but I certainly know enough to judge what I see.
Thank you for sharing your awesome talent with us here. It is to be hope you will continue to do so on a regular basis, so that we may all see what can be, when heart and mind come together to guide the hands of a Master!!!
