I have no training whatsoever as a machinist, and I do not own, nor do I have room for, any machine equipment. So as much as love watching machine work being done, and as much as I think I would enjoy doing some machine work, its just not in the cards for me.

That being said, I very enjoy watching You Tube videos re machine work and learn quite a bit. Your solution to the weak casting I think is terrific and really enjoyed watching the progression of the work.
