#214434 — Curta Calculators

If we're going to talk about really retro tech like pencils, why hasn't 
anyone come out with a reproduction Curta calculator? You can buy plans 
to build your own with 3d printed parts, but nothing really substantial. 
I can imaging that they would sell even if the relatively price is high 
and available in small batches and the patent must have run out on them 
years ago. People are paying $2000+ for them on ebay so I don't see how 
they wouldn't be profitable.

For those who don't know what this is:

The same way an imitation of any collectable is not profitable. People
don't pay $2000 for them because of their utility, they pay it because
of their collectability.

A whole shed load of precision parts in a mechanical calculator, which
would probably cost $millions of tooling to make in 2020. There are no
short cuts to that level of precision in engineering. Then you need the
original dimensioned drawings to copy the measurements.

Even making a one of as project might take years and those machines
were notorious for jams and other problems...

You can print a larger version of it on a consumer 3d printer.

Probably, but what sort of design life would that give you ?. My guess
is not very long, since these machines were stretching mechanical eng
state of the art when new and were not that reliable either. A lot of
heat treated steel parts, precision bearings and fine adjustment 
tolerances etc.

Played around with Teletypes and Flexowriters years ago and both could
be a real pain to clean, adjust and keep running...

A Curta isn't that kind of machine.  It doesn't "run".  You set a
number, turn the crank, set another number, turn the crank.

Sure, but that doesn't make it immune to jams and other mechanical
problems.

It'd still be interesting to 3D-print and assemble one, mind you.
Perhaps if I find myself in possession of copious free time, I just
might.

If someone wanted to spend the money, there are 3D printers that can
print metal parts with high precision. But the word 'cheap' is not in
their description.

Even assembling them is apparently pretty difficult without 
specialized tools. There's an exhaustive website at 
http://www.vcalc.net/ with info on them, including some factory drawings.

I can't think of any other high-tech product associated with the 
country of Liechtenstein.

A mechanical calculator, however exquisitely crafted, is not necessarily high-tech
by the usual definition.

However, there definitely are, or at least were, high-tech products being made by
one Liechtenstein company. Ah, maybe not. Crypto AG, a Swiss company, was
owned by a holding company in Liechtenstein, and Gretag was also Swiss.

That holding company was owned by the CIA & BND.

Hilti makes a wide range of sophisticated construction and engineering equipment.

Once I ran over a Hilti drill that the man forgot on the asphalt. I 
think it survived.

Quite likely, designed for everyday constant use, abuse, building sites
etc, by those with little mechanical sensitivity and who don't care.

If, like me, you sometimes buy power tools s/h at machinery sales or
car boots, you need to watch out for spares availability. No spare
parts for some older Hilti, whereas I can still get parts for a Bosch
power drill I bought new in 1983. Makita are good too...

For those prices you can afford two - one foe spares.

Late 1970s, went in person to Halifax Black & Decker depot for an
essential replacement part for my 1925 1/2" electric drill.

The Guy started at the left of a long shelf with the microfiche
(remember them?  Before ubiquitous computers?) binders, then the
ordinary ring binders, then the fat bound catalogs, thin bound
catalogs.  Very last item on the shelf, greasy, tattered, abour 20
pages, located the part number.  Brush holder, 3 on hand, I bought 2.

Circa 2003, I phoned B&D about a bearing for a B&D angle grinder
bought new in 1977.  Young-sounding guy on phone: "Wow!  That's an
*old* one." (They had other parts but not the bearing which I had to
get from a seals-&-bearing house.)

ObAFC: I recall seeing ads for Curtas in SciAm when I was in high
       school, late 50s.  Didn't grasp, at the time, what a remarkable
       thing it was.

I finally had to retire my Bosch saber saw that I bought in 1979.  A
piece broke that I could not get from Bosch USA--Bosch UK had it in
stock but wouldn't ship it to me.

Should have asked, someone here would have handled it. Have a
Makita jigsaw, again 20+ years old, but no noticeable wear on
the commutator and gets a strip down every few years for a clean
and repack grease in the mechanics. Ball or needle roller bearing
throughout, just like the Bosch drill...
