Rust Covered Vintage Calculator Restoration 

hi.. it would be nice if u show "things" that u has been restored works

Вы такой мастер, такую штуку разобрать , отреставрировать и ещё собрать! Моё восхищение!

There is a video, just such on RU-vid 'how vintage calculator operates'. Its very interesting how accurate it is

it's unsatisfying to see how he fixes it and that in the end he doesn't use it :(

Yeah I agree pretty good restoration but I do think they should have painted the numbers rather than leaving the metal exposed

Hahaha.....it is the main reason why they record all that......cleaning it up is just a thing on the side 🙂 (just kidding...)

If only someone knew how to work one!

My thought exactly! After all the hard work how about a demonstration of the thing working

There's a manual for it somewhere you just have to look for it. You'd be amazed at what's available.

Absolutely, looks nice now, but does it still calculate correctly.

Разобраться как пользоваться этой адской машиной ни каждый сможет а отреставрировать с разборкой - сборкой так это вообще жесть. Чел ас))).

Вот вот, не понятно, для чего эта штуковина.

@@Evgenya_22 Это арифмометр. Древний калькулятор. Принцип действия такой. Рычажками в вертикальных прорезях (где красные и белые точки) набираешь нужное число (27:15). Другим рычажком (08:23) выбираешь нужное арифметическое действие. Потом ручку сбоку крутишь на один оборот. На нижних барабанах видишь результат. Это очень примерный вариант. Это аппарат уж больно древний. Я немного пользовался (баловался) с более новым. Назывался "Феникс".

@@user-tp9bp5zl3l спасибо большое. Буду теперь знать. Вот какая оказывается нужная штука.

@@user-md2pq7pn9x он ещё счётный барабан не разбирал, вот там жесть. Что перепутаешь и всё. А колёса то номерные это ерунда.

Taking it apart is the easy part.

@@wandrinyew even that scares me.

@@wandrinyew it always amazes me to see restorers take apart such intricate items like this, then put them together again seemingly so easily! incredible memory and knowledge!

Amen to that!!

I guess the products from another planet cannot be made out but restored.

I agree I wanted to see if it worked!!!

We had these at school in the 1960's. They were brought out on a trolley and placed on our desks. This was before the days of electronic calculators. Electronic calculators may have existed but were only affordable by industry and the science community. I still have a Sinclair calculator that came out in 1972. The mechanical calculators were more of an exercise in showing that numbers could be handled by cogs so even then they were a novelty rather than for practical use. Charles Babbage and Ada Lovelace didn't get a mention. In general we were expected to do calculations in our head or long hand. We were also taught to use slide rules, Napier's Bones and logarithms. Comptometer machines were still being used in industry and I remember first seeing an electronic computer held in a environmentally controlled room. Much of it seemed to be large reels of tape and no monitor. The rate of technological change has been mind boggling and continues to be so. Not only has the computing power changed dramatically but the size has as well. I still hold micro sd cards in awe.

The transition from mechanical to digital was a game changer.

I used one of these beasts in university in the early 70’s. I also used one of the first Hewlett-Packard calculators that cost $125 in1972 dollars and only had 4 functions, +, -, x, & /.

@@anearbytown Imagine how some of us feel who came up in the 1990's with the home computer revolution now seeing the dawn of quantum computers. Instead of bits they use qubits. I remember hearing rumor of them in the late 1990's. A friend of mine would tell me that the people working on them at the time were having trouble controlling the states of the qubits. Now quantum computing is a reality. So I imagine that the computing revolution in some form may start all over again. Time will tell I guess.

@@zband9016 My introduction to computers was at college where they had printer terminals i.e. no monitor. The computer was not on site so it had to be dialled up on a conventional telephone and once connected you put the phone in a cradle near the keyboard. The input and output was all in printed text. To save a program you sent it to a punched tape device that spewed out narrow rolls of paper with holes punched in it. My tutor had worked on the Atlas computer using Fortran. The college also had some ailing programmable calculators that required you to write code to move values in and out of the registers. This was great for understanding how the computers worked. I am struggling to get my head around quantum computing. I have yet to see an explanation that is simple enough for me to understand how a program would work! It amuses me that when I first saw Windows for the first time I though it would not catch on.

He forgot to do that and then was lazy to disassemble?

I agree 👍

There was also slide rulers that you could use

Dope indeed

Bah.....I could EASILY put it back together and with ONLY a dozen leftover parts 😉

When I disassembly an engine I always putt the spare parts right into one of the cylinders. But i wouldn't have a slightest idea where to put the spare parts and screws into that machine 😄

Yes. I agree. You just can't reassemble without any reference

Play it backwards

Or ..More probably ....totaly MAD !! Once he saw electrical calculators come in .............!

Agree wholly. But the video producer strangely is not commenting on the fact that it most likely doesn't work. Chicken.

I remember guys making an excellent living, going from one insurance salesmen to another in Perth Western Australia. They were offered at A$75 each, and rapidly became the workhorse of an entire financial industry.

No need to bet on it - it doesn't work. I could tell from experience when he was taking it apart it will never work again. No regard for the timing whatsoever, parts missing in the reassembly of the tens carry mechanism, demo of the clearing appears to clear the carriage to all 1's instead of all 0's...pinwheel cylinder completely blocked, and when "finished" the input control register is at all 9's while the cylinder is at 0. MrRescue is just glad that he could put this back together to something outwardly resembling a mechanical calculator ... but it's no less of a boat anchor now than it was at the start - it just looks shinier :)

Yes. Have we met?

Yea I'm on thankgiving break so I'm bored as hell

Does not work. Downvote

Does not work. Not excellent

I doubt it worked as it looks like the gears weren't aligned correctly
