- My 1957 Friden STW 10 mechanical calculator is due for an appearance in a high quality documentary about women that made mathematical calculations for NASA. But before the filming, I need to make sure it works.

I've translated the Japanese for anyone like me who came along a year too late:
[Title Card: Cosmic Front ☆]
[the star is very important]
*Male Narrator:* America: those who undertook the Apollo program, and who did great feats. At space research facilities, many unknown women played a part.
[jump to Katherine Johnson section]
*Female Narrator:* In order to do this, humans made important calculations. The tools they used were pencil and paper…and a mechanical calculator.
[Caption: Electromechanical Calculating Machine]
*Female Narrator:* Inside are packed many thousands of parts. With the turning of gears, it goes about its mechanical calculations. A collector was kind enough to show us a period calculator.
[Caption: Marc Verdiell]
*Female Narrator:* For instance, 12 x 312 is…[clackclackclackclack]…3744, and there it is. But how is this calculated? The calculator splits it into the ones, tens, and hundreds place. First it multiplies the 2 in 312. 12 x 2 is 24. Then for the tens, 12 x 10 is 120. Adding 24, it's 144. Finally in the hundreds, 3600. Add it all up and you get the result: 3744.
*Extremely confident Japanese Marc:* Multiplication and division took a few seconds, which compared to doing it by hand, was far faster. PCs today would be done in a fifteenth of a second.
*Female Narrator:* What this calculator can do is high speed operations. Using this calculator, Katherine could make complicated calculations and complete the researchers' requests.
I think it's incomprehensible that someone sat down, grabbed a pencil and some paper and said, "OK, lets design this complex piece of machinery". I mean, how do you even START such a task? Amazing machine!
Any machine like this is an improvement of an improvement of an etc...
Not only that, but to make it from stamped steel parts! Amazing.
@@PaulMauser Indeed I have an old version of another maker. It's the 1830 calculator (machined) with the 1890 parallel keyboard part (mostly stamped) without the multiplication register and it's automatic turning and shifting as it has to be done by hand.
exactly its entirely unbelievable how complex and obvious it is at the same time. Just a ridiculous example of humans desire to learn.
It is not only one person who will sat down who has invented such complicated machinery it's a whole design team and the improvment is made all along the time i mean evolution step by step or over generation from the previous one .
Ms. Johnson died a little over a month ago, in February 2020. Glad this was made prior to her death. That is an astonishing piece of machinery. Great job debugging it, and great video. It is interesting that the Japanese recognized the significance of Ms. Johnson's work.
I like the Japanese version of you who did your voiceover
Yes I should hire the guy for all my videos :-) The Japanese lady narrator has a very beautiful voice also.
absolutely hilarious, i didn't expect this surprise-comedy
It really stood out.. I guess Japanese men of authority have to sound ticked off?
When I saw your calculator video Katherine Johnson was the first thing I thought of. It's great that you were part of a documentary that featured her story. That's so great!
Could be me.
"Tomorrow the TV people are coming and I totally forgot the damn thing is broken. Oh well, got a long night time, so no worries"
This is one of the best peaces of engineering I've ever seen. Someone had to figure out how to do these functions through mechanics and then package it in a case, while also being reliable and completely accurate
In 1964 I began my career at Hughes Aircraft Co. My first job was with crystal filters for radio links and the R&D section was where I was assigned. Filters for both the Surveyor Moon lander and the Apollo Lunar Module were made in the same room, but not by me. In finding some of the right parameters for the filters I assembled and tuned, the chief engineer would let me use his Friden that would do square roots. I would go to the machine on his desk and put in the numbers and hit the odd button that started the process. Then I would go and get a cup of coffee to await the results, it was that slow, and extremely noisy. A year later and that engineer had one of the first Wang desktop calculators with the side unit for that purpose. Thanks for the peek inside and the oiling tools needed. I just might be able to reinvigorate an old IBM selectric I have.
I’m just learning how to service manual typewriters, and they can be rather complex machines. That Friden calculator would scare me to death if I had to work on it!
Who knew you had such a beautiful Japanese narration voice at the end! :P excellent to see global interest in such a fantastic machine!
As always awesome. Like your videos very much. They are made with passion and have very high quality.
As alays, the TH-cam algorithm seems to follow someone else and give me their first choices. After following the Apollo Guidance Computer series, it has completely forgotten my interest. I would have been very interested in this clip, because of Marc's references to 'bending' as a legitimate adjustment.
Many years ago - like half a century ago - I worked for NCR (National Cash Register) originally of Dayton Ohio, although I worked for them in London. NCR of course made cash registers, including the ubiquitous 100 Class. (In Britain, they were refered to as 'a till', is that the same?) The CRD (Cash Register Division) covered the whole range of similar machines, right up to vast, hotel billing machines (I can't remember the class.) I worked for AMD, Accounting Machine Division which covered everything from the simplest, hand cranked adding machines, up to the 'mighty' Class 31 mechanical accounting machine. (And beyond, to the Class 31M multiplier.)
When I first went to the training school for FE's - at Brent Cross, where the shopping mall is now - I had an instructor named Ron Tarling and it was he who introduced us the the strange set of tools most of us had never seen before. Bending bars. These were a set of different types of hard steel rod machined (in some cases forged) to bend a specific type of metal strip.
Your Friden was made up of hundreds of rods, bales, levers and pitmans (all American terms hardly ever used in British nomenclature) that were just stamped metal shapes , which could be altered to give a slightly different effect. Let's take a very simple 'teeter-totter' lever, pivoted roughly in the centre. If the 'input' of motion is on the left and 'output' on the right, by bending the flat of the right side with the appropriate bender (I can see it now) it was possible to shift the 'throw' of the output to give either more or less motion without moving the 'home position' of the input. Similarly, with a 'Pitman' - which, for my British colleagues, was a connecting rod, just a flat strip with a hole at either end which transmitted colinear motion - it was sometimes necessary to move the home position of the output end, by gently peining the flat of the pitman on the tiny anvil that was part of our tool kit.. Of course, it was not possible to reverse this process.
To this day, I can remember the aphorisms of our instructor Ron Tarling, one of which was "Metal don't f'in grow!" and another was; "You can't bend it straight!" and he was always referring to 'elonginated 'oles'. When I eventually ended up, many years later, working for another, even bigger, American Multinational, most of my peers had degrees and one or two of them Doctorates - I had nothing. No qualifications whatever, but what I learned from working on mechanical accounting machines put me on a level with and sometimes ahead of my much better qualified colleagues.
Very interesting vlog Marc and I spent the first couple of minutes of diagnosis yelling at my screen; "Where's the hand crank? You can't keep stabbing the power input like that!"
Love the music always going on when you're showing off your collection.
Mechanical calculators are the second best things after mechanical computers.
What a beautiful machine. I'm very intrigued. Love these videos! thanks!
i am in AWE of anyone able to figure such a thing out after so little time spent with it!
I actually spent quite a bit of time with it during the initial restoration, which was way harder. See here: th-cam.com/video/1X3ivZfSfW4/w-d-xo.html
Tangobaldy is in awe of this machine. It can do math better than me. Good video.
Great video Marc...
Just blows my mind how the human mind can design and build something like this.
And all without the help of any computer. I'm 100% convinced that nobody could still do that today, except engineers of a certain age perhaps.
Great video, Culious Malc!
Arigato goazaimasu, thrillscience-san.
Fascinating as ever. Do you or the Museum have any examples of the Marchant mechanical calculator, which Richard Feynman mentions being used in the calculations for the Manhattan Project at Las Alamos?
Que joya de canal, gracias!
I looked if there were subtitles, but the only thing I got was stuff like "Bo Davari must give me kira quinoa soup greens on this" - I don't think that's a good idea with such a delicate piece of equipment.
When Marc operates the machine: "Sankyo for external kappa nooooo customer I messed up"
You forgot to turn off external kappa if you multiply by 312, but it's a very easy mistake to make. At least you used non-gmo lubricant.
tried youtube captions, to translate japanese for me. it was hilarious disaster, because it still thought it is in english :D
Awesome calculator and maintenance job.
awesome video thnx a lot
Wow, lucky you were able to fix it in time.
The whole thing is a pretty amazing feat of engineering.
How long did it take for you to diagnose and fix overall?
This time around, two days. The original restoration, from entirely stuck to everything mostly working, two month (see here: th-cam.com/video/1X3ivZfSfW4/w-d-xo.html )
Marc your presentation and productions are brilliant! CMP Curious Marc Productions 👍😀
Nice to see the movement without the plastic parts.
this is interesting please more video
I don't understand the people that downvote things like this. Do they go outside and look at a gorgeous day, swear, and say "I @#$#@" hate this!" and go back inside? And I thought I hated everything..
WooHoo - - a real TV star now!
Built to last.
If for any reason we had to rebuild one of these mechanical calculator I bet we don't know were to begin with :-D
There is also made a movie of it, Hidden Figures from 2016, it deals about the woman and the racism of those days,
you can see Katherine Johnson working on the Friden.
Friden SRQ??? Is it that famous machine that can calculate roots AND squares???
Any theories on how the metal parts which you had to re-bend changed? Heat in storage, possibly the jamming of the mechanism when you tried it after being in storage?
It's not that it didn't work at all, it did not work reliably. I am not sure what made it worse - machine jamming might have been the last straw.
My guess then would be since the troublesome parts are not made of hardened steel that over the decades their positions shifted to the point where it became unusable. Kind of like guaranteed obsolescence.
Marc, you sound great in Japanese.
I know. I surprised myself.
might going to be a nightmare to get it back together again.
Would love to learn more about Friden refurbishment
He gave us a link in an answer on a question earlier, here you go: th-cam.com/video/1X3ivZfSfW4/w-d-xo.html
It is truly a wonderful piece of mechanical art!
Watching this mechanical monster you can see writing programs for electronic computers was just around the corner and way easier lol.
PS 12:07 first shift registers
Might want to see about putting the language of the video in Japanese so that the end clips auto-translate properly for subtitles. otherwise... that's a sexy mechanical multiplier. serious ASMR cred happening right there.
I actually tried and it's pathetic. Two lossy stages in series (Japanese speech recognition and auto-translate) and the output makes zero sense. And I can't even remember what I said! I'll try to find a Japanese friend that can translate this correctly and put official captions. In the meantime, enjoy the nice sounding Japanese!
all those years of anime watching are paying off if I can pick up a couple words from the Japanese section lol
Justin Noker what are they saying all of us are stumped.
Hi, I have one similar - a DW10 which is similar to yours but without the multiplier pad. Using one of your other videos, I’ve managed to get it mostly working - the only things that don’t work correctly is that following a division, the machine doesn’t reset until you press one of the carriage shift keys, and that the carriage return key is rather erratic in its operation - and it doesn’t lock down. I’m somewhat afraid to go further with it for fear of losing what I have so far. Anyway, here it is:
th-cam.com/video/sw-uCaU18n8/w-d-xo.html
Did you use WD-40 before? That stuff always gunks up like crazy.
Yes, that's probably part of my problem. That machine was so stuck so hard I ran out of other options at the beginning of the restoration process. But the moral of the story is the same: stay clear of WD-40 if you can.
I don't know if I mentioned it before but WD-40 is "Water Displacement" formula 40.

This made me cringe a little......
Mineral Oil
Seriously. WD-40 is mostly a mix of baby oil, Vaseline, and the goop inside homemade lava lamps.
wizardry
5:14 So... It's basicly a debugger.
I would have used naptha not alcohol, but good choice of oils.
我有一台相同的，也是不能工作，花了3个月才修复
That Japanese series looks to be really interesting. Makes me want to learn Japanese…
Now you're famous in Japan too. 🗾⛩
Kudos to Marc for figuring out that mess of documentation. Geez. You're a better man than I am. Or at least a lot more patient one. I'll bet that was a good feeling when it successfully reset.
I didn’t know you spoke Japanese ... heh heh heh
So tomorrow Japanese TV people making a documentary are coming over to film this horribly complicated piece of equipment that doesn't work for some unknown number of unknown reasons.. no pressure :D
The Japanese shouldn't have filmed it on such a wobbly table!
Amazing machine ... Babbage 2.0
Easy.. once you know.
