Hi, i've come across to this video & would like to know your opinions on that, is it trustworthy. Can i trust his teachings?
Thank you all who take the time to help a little beginner to the right track
Get a copy of Y14.5. Videos and other books can help explain things better, but in the end if you get into a discussion with someone, you had better reference the STANDARD and not some random video on you-tube or some obscure book you read on GD&T. Not to imply that they may not be valid but again, they are not what you would use in court.
