I find complex mechanical devices amazing. Especially that someone could envision all those cogs and wheels in their head to produce the final mechanism, let alone all the machining and assembly required for each one. I can get my head around electronics schematics fairly easily after 40+ years of following them, but I don't think I could ever really understand a complex mechanism like that calculator. Funny how it will still work in another 100 years where all our electronics will have failed after half that! Progress!! Keep up the great videos.
I see it exactly the same way as you do. I can hardly imagine how, in 1890, when Mr. Odhner began producing this remarkable machine, he managed to create such a precise mechanism. Lathes did exist at the time, but I didn’t realize they could already achieve such precision. It’s fascinating to think that this machine will likely still work 100 years from now. I was struck by the fact that I didn’t see any mechanical wear inside, apart from the bent metal plate that was causing the mechanism to rub. But the mechanism itself is undamaged. Thank you so much for your support!
I’ll give it a try. I’ve already looked into spare parts, but it’s going to be hard to find them. The missing button for the slider and the crank handle...
Exactly, it cannot handle negative numbers. However, in the left register, there are white and red numbers-red numbers are meant to indicate negative values.

Cool machine. Must have cost a fortune to manufacture. Hopefully you'll fully repair the machine!

Nvm you covered that
