Stumbled across this young man's project page and it does my heart good to see him practice the machinist's art to a very high level of expertise. He can't be older than his mid-20s, but his work would put a professional master machinist with decades of experience on notice; with precision to the nth degree.
Case in point -- at timestamp 9:23 he indicates his finished machinist vise base with "0" runount in the vertical and horizontal plane. That kind of manual machining precision takes many a lifetime to achieve; yet he's just a "kid". His channel is worth watching -- and learning from.
There are still people that can use their mind and hands to make things to a level of precision that CNC machines can't yet achieve.
His skills with metal bending and shaping are also exemplary. He built his own tool cabinet -- just amazing
