Slide Rule Roundup -- 1955* Duplex Engineering Edition

- Опубліковано 12 вер 2024
- An overview of some popular engineering slide rules available in the mid '50s. Let me know your favorite below, whether or not it was one of these!
* Some slide rules in the roundup were made in later production runs than 1955. Also, the Dietzgen N1733 was not available until 1956. The 1733 was available earlier and was more similar to the K+E 4081.
Thanks for this great video! That was interesting to see the side by side comparisons. I'm a K&E 4080 and 4181 fan, and just recently acquired a Relay 150. It is bamboo w/celluloid, and also has the trig scales on the base, rather than slide. That was actually the first thing that caught my eye when I took it out of the case. Keep up the good work, and thank you again!
There is a similar Post/Hemmi slide rule to the Relay/Ricoh 150, but I think the Relay ones are much easier to find, and were produced into later years (making good condition ones more prevalent). It would definitely be on my roundup of slide rules with the asymmetric log-log design, but I don't have enough of those rules to make one. Earlier 4080/4081s use that log-log design but have the trig on the slide.
Thanks for the video - My family has been a K&E family. My Dad had a K&E 4080-3 (10") from WWII my Mother had a 4080-3 from WWII and a 4053-5 (20" PolyPhase) from the 50's and I have a 4080-3 from 1968. My Dad was an engineer, my mother was a professor of Stat and Econ. I went into Computer Science and did not use the slide rule that much after collage. Thanks for your videos to bring them alive again!!
I have the post 1460, now I understand it better. Good video
Just like the Dietzgen that I bought in fall of 1964 before heading off to University of Tennessee.
After a dalliance with the Pickett super rules (the sybaritic excess of the N4-T!), I have settled into loving K&E 4081 best of all, with Post Hemmi second. The clean simplicity is attractive, especially for instance the cube root scale, and AB pair. Hey, if I want a 4-digit cube root, I'll use a calculator. Plus I love the aesthetic, with the mahogany peeking out from under the ivory celluloid: smooth! I'm thinking of making one, too.
As I think comes across in the video, I agree about the 4081. I could even live without DI (some earlier versions have this layout with 6 LL scales but no DI, giving it 3/4/3 symmetry on both sides.)
Although this is an older video, it brings up a question that has nagged me: IMO the Versalog outshines the rest by quite a bit, yet K&E didn't really (arguably) surpass it for roughly a decade with the Deci-LON. Add that with the Versalog costing less, I question why it did not dominate the market. -- This all got me wondering how old my Versalog might be. It appears to be from 1955, and is still almost as good as new.
I forget if I mentioned this in the video, but I really miss A and B when using an original Versalog.
Thanks for another great video. Do you have any business slide rules in your collection, such as the Picket 400 or the Farber-Castell XX/22?
Thanks! No business rules at this time, sorry! I have mostly general purpose rules. I gravitate toward the log-log engineering rules such as these and the basic rules you see in other videos. I think a future video might pit the Versalog II against the Deci-lon.
Would you like to borrow one of mine?
How about a brief comparison of different layouts? Mannheim vs Darmstadt vs Rietz. (Perhaps you did this in one of your early videos. If so, please forgive me. I'm old & forgetful now. :) )
Gary, maybe in the future when I need more material! :-)
I have thought of doing a layout comparison video. I make a few comments about this in some videos, but I could say much more about it now that I know more.
I would love to see a sequel to this great video aimed at sat the late 60-early 70s and include say the N3-es. And the versalog II. Thanks
Thank you for this great video. I am an electrical engineer in Australia and I like to buy a slide rule. I was given a German precision slide rule with an unusual scale. This is in a museum now. Could you recommend a brand. Thank you.
I like the the Aristo Studio 968.
Sorry I didn't see this comment earlier! Aristo makes several nice rules. I like both the 968 and 970 rules. I don't know what else is easy to obtain down there, but probably you could get your hands on a Hemmi rule. I bet the typical American brands Pickett and K&E are not as common for you.
Thank you. I got a Rietz Farber Castell 1/87 for pocket money on ebay. Rietz is a good design. Because of your clip I like to get my hands on a Aristo 968. Before 1970 all engineering work was done with slide rules. 3 digits are good enough for all practical engineering work. It is not difficult to use a sliderule - I used a calculator to control but I don't need it anymore. When I have the Aristo I like to use it for Calculus and Complex numbers. (:
I bought an Aristo 0968 Studio sliderule. My concept was to buy a Rietz and later a duplex sliderule. I was glad to get the advice from Prof. Henning. Now I can see why he likes this two sliderules. If you also go along this advice you will not be dissapointed. Even today you can use this sliderules for Engineering calculations it will do the job. I recommend to download the manual for the model you have. It makes the training easy. Thank you.
Versalog II vs. Deci-Lon..... please make it happen!!!
If not, what would be your knee-jerk choice?
Haha, I am planning to have this in the future -- check back!
Finally got around to this -- check out the new video!
What about the Pickett? Was the N803-ES available in 1955?
I don't believe the 803 was available until the late '50s. Matching my criteria in the video Pickett would have had the models 2-T, 4-T, and 800 available. My pick would probably have been the Model 800.
How could you eliminate Hyperbolic scales and call it Engineering Edition? You just ruled out Electrical and Electronics engineers and bridge engineers and quite a few specialty mechanical engineers. Are you saying they enjoyed deriving hyperbolic values the multi-step method. For instance in circuit analysis and chip design, hyperbolic scales are invaluable. Oh well its your channel:-))) Just jerking your academic chain if that were possible.
Hahaha, this would have been a much harder video to make if I included "vector" rules.
