The Rheinmetall SASL mechanical calculator

[@stephenfreeborn]

Thanks Jaap. I love the sounds it makes. Good thing no exposed gears. Sounds powerful enough to take off a finger. What a wonder.

[@guldilo]

Great! A new video from Jaap! Sit back and enjoy!

[@DreQueary]

This has to be the loudest calculator ever. I cant imagine a building full of them. haha

[@jaapsch2]

It is pretty loud but I think the video makes it come across as louder than it is. I think that the shifting of the carriage might be worse because it probably shakes the whole desk it is on.

[@Pembolog]

that calendar is in phenomenal condition

[@robertlozyniak3661]

It is astonishing how we went from such machines to smartphones.

[@CalcuClark]

This machine is still on my wanted list! Fascinating machine!

[@bss1250]

Very cool machine, I always find it interesting how some companies simplified their controls going into the 1930s (like Marchant, MADAS, and Mercedes-Euklid) but others kept making machines with unlabeled levers protruding seemingly randomly from the machine

[@jaapsch2]

Yes, this one has so many levers everywhere. I even forgot to explain one of them (the counter direction switch at the top right of the keyboard).

[@GrumpyTim]

What an awesome machine Jaap, they've tried to cover every conceivable need with that machine. The diary that you showed at the end is a lovely thing to have too, I really like that.

[@jaapsch2]

Yes, that diary is a fascinating historical cultural artefact.

[@someonespadre]

Wow what a machine.

[@iBlimp]

I love this channel. Fan always here

[@ChrisStaecker]

Wow- very ambitious machine and video! The way the knob at lower left spins like crazy at 8:09 looks dangerous. Does it stop itself if your finger gets in the way?

[@jaapsch2]

That is the axle of the electric motor. It was very handy to have that so accessible so that I could crank through a cycle while I was servicing it.

[@myusualnickwastaken]

Those multiplications and divisions seem like a good way to break a finger that happened to be in the wrong place.

[@gregreynolds5686]

Wonderful piece of engineering - did it take much effort to get it working?

[@jaapsch2]

Not really. All it needed was a little lube, and of course I had to replace the power cord. It was a bit tricky to get the covers off the carriage, but other than that it was no trouble.

[@marcomartinello03]

Love it, what's the name of the plug standard?

[@jaapsch2]

I mostly see these plugs called NZU-1, so I presume that is the name of the standard. They still make new replacements because these were so widely used.

[@marcomartinello03]

Thanks!
