Thread: ARISTO WERKE 01068 50 cm. SLIDE RULE

jeez Brian, can you put a picture of it up? For those of us who remember using slide rules it must be a thing of beauty.

Brian,you would be an interesting bloke to have a beer with. Pat

Here are a couple of photos of the Aristo, a bamboo Hemmi 50W that my father gav me for my 17th. birthday when I was in Year 12, and a Faber-Castell 2/83N I used from about 1960 to around 1977-78 when I acquired a Texas Instrument electronic scientific/engineering programmable calculator.

These were about $400 then. A few years later you could buy one half the size at K-mart for $20.

Slide rule, I doubt I would even remember how to do anything other than basic multiplication on one now.

I went to a Texas Ti59 via an Elcon(m) and HP45

Survey calc 1 was still done with a push button, pull handle mechanical calculator and Chambers 7 figure logs.

Here is a photo of the three with a 12" steel rule for size.

Basic multiplication was all (and still) I could remember when I dug the Hemmi and Faber out to show my son when he was in Year 12. My son was fascinated and taught himself to use them until the novelty wore off.

Once you got one of those TI calculators, you dumped the slide rule instantly. They made life so much easier.

Even if they did cost an arm and a leg, IIRC the Ti59 cost me around $400 in '78.
I can remember writing a number of 'programs' to calculate vertical curves, missing line calcs etc.

I have my father's Hemmi and my own slide rule I used in high school in the Sixties. It was frowned upon (none of my teachers knew how to use one. Dad had bought it for me and taught me how to use it. He was an engineer.).

I've still got a slide rule somewhere too, that I used for First Year Fitting & Machining. I might be able to multiply on it but nothing else these days.
