First, his tool post reminded me of CEE then came the scale.

As a young design engineer in the rubber and plastic industry I designed rubber mills for Francis Shaw & Joseph Robinson. This was everyday stuff back then 800hp gear sets, huge bronze water cooled bearings on the journals 90” wide 24” dia rolls some micro finished other’s helical grooved. Loved every minute before I went or king for Loctite. Then of course we in the U.K. began our great decline and deindustrialisation, now there’s no trace of these once colossal companies and all that skill base is almost all dead and buried. Makes me so sad that so few today have work they can take pride in, beats the work in a call centre by some margin and what’s the point of burger flipping by comparison. Nothing like the smell of cutting oil.

Don’t mock the inch, fractions are absolutes, base 12 is a pretty good mathematical system, ask a mathematician. More difficult no doubt than base 10. Engineering wise the very first standards were set by Joseph Whitworth in 1841 and he measured to one millionth of “a banana” and designed the most efficient threads in terms of clamp to applied torque, to that date. His measuring device could show the expansion of a metal bar by the heat from a finger, 140 plus years before everyday accuracy of “a thou”. True engineering genius. Remember too that with base 12 and fractions there’s no rounding errors commonplace in metric, the blight of pcb layouts.

By age 14 or so, was using a 20"X 60" (memory, but close) flat-belt-driven lathe and learning how to deal with worn out head stock babbit bearings,. And learning to use a KT horizontal mill. At 18, a major machine tool mfgr gave me the responsibility to do the final inspection and sign offs on machines worth (at that time) ~$250,000. I Had no idea what that responsibility meant at the time, but not a one of my machines ever got questioned by any customer; they WERE within spec. No brag; fact.
