Nice!

 

Dad had one many years ago.   Knew how to use it too.   

 

I was probably 15 y/o last time I saw it.  No idea what happened to it.

My only slide rule was a Post Versalog bought in 1959 for a high school math class.  I used it until I got out of the Army in 1969, gave it to a friend, and never used one again.

I have about a dozen I have collected over the years.  3 or 4 Pickets including two N-515-T that were made specifically for Cleveland Institute of Electronics (CIE), one that is round, a few that are of bamboo construction including one specifically for solving marine navigation problems, a couple others of aluminum construction, and one E6B.

 

The ones made for CIE are unique because they have the standard scales plus scales specifically designed to solve electronics problems.

 

I've included PDFs of the CIE manuals for those interested.

I bought this Pickett in '75 because electronic calculators weren't allowed in Navy A/P schools - at least at NAS Millington TN.

All right. I was going to google it but figured I would get a better answer here and I wanted to hear all of the wise crack comments to lighten my day. 
 

What is this thing you speak of ?

and what is it used for ?😀🤔

Circular slide rules are weird

 

I used to have several 22" regular slide rules, 2 aluminum and 2 bamboo.

 

Also a 6" that I kept in the glove box along with a small 5x7, 5 section spiral bound notebook that I used to log mileage, maintenance,  trips, and miscellaneous.

My freshman year in college 1973 was the first year they started allowing the new fangled hand held calculators to be used in class. Mine was a simple one with a crude LED number screen.  Used it in Calculus for Architects MUCH simpler version than for Engineers 

 

I’ve got several slide rules that were my Dad’s

Back in the BC days  (before calculators) people wanted a way to do certain aritmetical functions faster than pen and paper. 

 

Someone came up with the idea of using log scales to do that.

 Back in the late 80s a friend found out I was interested in slide rules and gave me one as a gift.  Not knowing how to use it I went to the library and found the above book.  The third time I went to renew my loan the librarian told me I could have the book for $5.00. 

 

The book that started me down the rabbit hole.

 

 

I still have it.

A nice rabbit hole. 😆

Wow! Cleveland Institute of Electronics. Many fond memories of their ads back in the 60s and 70s, in the backs of Popular Electronics, Electronics Illustrated and the ham radio magazines, marketing their correspondence course to pass the FCC First Class Radiotelephone License exam.

I learned to use a slide rule in High School, but rarely used one. When I joined the Navy in ‘79 I bought a Texas Instruments  calculator for BE/E school - Basic Electricity / Electronics.

I cannot remember the model number of that calculator.

Some time in the late 90’s a co-worker gave me a slide rule that if it had not had instructions for its use on the back of it I wouldn’t have remembered how to use it. 😂

 

I will break it out later and take a photo of it yo post one here.

I've still got mine somewhere from school days. Doubt I would have any clue how to use it now!!

[John Kloehr]

I still can use mine, though have to think a bit for some of the scales.

 

I still keep a plastic one in my garage toolbox, have not used it in a few years. The nice bamboo professional items are queued up to get framed as an office display.
