Calipers and such

[AtomicClock]

Once you have both, you'll be surprised how often you use them... or not, if you hate fun and adventure

I have never used my micrometer. I use my calipers less frequently than it takes for the battery to go bad. SIgh. I tried to find a nice, unpowered set of vernier calipers, but the only lefty ones cost an arm and a leg.

Don’t buy lefty ones? Just a $5 set of dial calipers from harbor freight or plastic ones from Home Depot will do. Hold them upside down or backwards if you insist on using your left hand…

Verniers are fun, but don’t do that unless you enjoy confusing other people. I use them as my engineering age detector.

I was planning to keep them with my slide rule collection.

With your abacus?

With your abacus?

No. I'm not a doubler.

I have two slide rules and an abacus that I used to use on my Chem Engineering exams. The slide rules multiply great, but you can't add. The abacus (actually the Japanese version called Soroban) let me total up long columns of numbers quickly. Most younger engineers don't need that any more. Calculators, laptop computers, and smart phones can do it faster and more accurately.

I do it all in my head.

More and more, the numbers you need to manipulate are already in the computer. And the answer needs to end up in the computer. So it makes sense to just do the math there, too. I don't understand why keyboards still have the 10-key on the side. Who has lists of numbers on paper any more?

Calculators are really just for educational situations, to enable cheat monitoring.

Carter’s Law is that it takes on average only two digressions before a topic becomes about something unrelated to the original topic

You are right. We went far afield. I moved the digression to a new topic.

My first thought was brake calipers... somebody has a question about replacing calipers and bleeding their brakes?

That is a go no-go gage.

I was planning to keep them with my slide rule collection.

When I graduated with my B.S. I gave my primary slide rule (Dietzgen "Microglide" Decimal Trig Log Log Duplex with a cherry on top: https://americanhistory.si.edu/collections/nmah_1320190) to my roommate who had switched from architecture to chemistry and had to do an extra year. I knew I'd never use it again. From a sense of excess caution (and maybe nostalgia for tough times past), I kept one of the cheaper metal Picketts for some years, but don't remember ever using it.
