... isn't this like a poor-man's torque wrench and much more complicated
at that?


No, it is very practical. I try to be a minimalist with many things. Why
buy and store a torque wrench when it is not truly needed? Then there is
the ratchet mechanism. When it gets old how do you know it is still
accurate? The suitcase scale I can easily check.

I might comment that at one time I worked in the Edwards AFB (USAF
Test Center) shops where we had a "Torque Wrench Shop" where the guy
tested and recalibrating torque wrenches. I once asked him how many of
the torque wrenches turned in for calibration actually needed
adjustment. He said "all of them, even the new ones".


Exactly what I meant. I never really trusted those things which is why I
never bought one.

On the other hand installing and correctly tightening 56 spark plugs
in one engine is difficult to do without some sort of instrumented
device :-)

The calibration bench was simply a shaft with an arm to which weights
were added :-)


Bingo! Got to keep life simple.

It is called a "dead weight tester" and is commonly used where exact
measurements are required :-)
