Good video RickB.
I'll say this as I've said it before, Neil Keller of Kustom Ballistics the gentleman that invented the machine checkering fixture being used in the video built a custom Colt 1911 that by far is the nicest custom Colt I've ever seen, bar none.
That did not set well with a couple of big ego smiths on another forum I frequent, the only thing I can say to them is the truth hurts.
I also know what John, the smith in the video is saying, you get to watching all the lines or in my case dots I'm milling you are glad when the job is done.
Best Regards
Bob Hunter
