There's an odd thread, called the Leica thread, that is used on
photographic enlarger lenses. It is specified as 39mm in nominal diameter
but 26 tpi in pitch.

I'm wondering what other monstrous metric-English combinations are out
there?

I seem to remember that some European bicycle parts had similarly stupid
threads...

Shaft nuts---the thin round nuts with notches in the rim used to retain
bearings
on shafts. Metric diameter, English pitch.

My '70 Datsun Roadster has some bolts that are 6.5mmX28tpi. Took a while
to figure that one out.

There's a lot of specialty farm equipment where english nut and bolt wrench
sizes were speced. Not the bore and thread, so they are metric if that
component was built on the far side of the pond. Not a problem till you lose
a bolt or nut. Fastenal thought I was nuts, even they hadn't seen that.

My JD5310N has some of this, some pure metric, and some pure english. All
the fastener lengths are non standard. At least you can order replacement
fasteners from JD, just hold on to your shorts when you see the bill.

There was the unfortunate era of "soft metric"
where the diminsions of an "inch" part were
simply converted to 3-place metric and called
metric.

Lead to all sorts of ugly roundoff errors for
the designer that allowed the tolerance to build up.

IIRC the thread was Cycle Engineering Instutute (CEI)

Set the lathe for 26 tpi and make whatever you needed.

Not as bad as the BA series of threads, where the sizes and pitches
are nominally english, but based on metric measurments.

I could send you about 5# of 1-1/2 inch long HHCS in 1/4-20 thread with
10mm heads.

And they ain't bad 6mm X 1.0s either. They're real honest-to-God 1/4-20.

God alone knows where those came from. I've never seen them as original
parts on any of the wheelchairs come into our shop. Been some chairs go
out with them though.

I have some similar to those . I think the thread must have been spect.
by the US Co. but the heads wernt so the Asian mfgr. used metric for the
benefit of the assemblers who have metric tools. Or something like that.

I was told that this resulted from the "Marshal Plan" where many
surplus US [inch] machine tools were shipped to Europe after WW2.

While transposing gears are a possibility, you can no longer use
the half-nut, so there is a significant production penalty to
generate metric threads with an inch lead screw.

Thus the "compromise" where diameters, lengths etc. were metric
and the threads the closest possible inch equivalent, i.e. 26 tpi
close to 1.0 mm pitch [25.4 tpi]

No documentation, but sounded plausible.

Car tyres have metric width and imperial rim diameter. Except some
(rare) American(!) rims, which have metric diameter.

I have heard that the Italian model engine manufacturer Super Tigre
used to use bearings with metric outside diameter and imperial inside
diameter. I have never seen a bearing like that myself, though, so I
can't vouch for the accuracy of this.

My US-made ATK had a ball bearing in the swing arm that had an imperial OD
and a metric ID (or the other way round?). I fell off the bearing dealer's
chair when I went there (had no time to measure, so I took it there
directly; needed it anyhow) and he lifted his eye-browns more and more the
more he measured. That was a Tuesday. Friday night off for a race. No
chance to get that bearing!
Made some kind of funny boring bar that was driven by a hand drill and
berserked two bigger holes into the (**very** nicely TIG-welded!!!) frame
and made a new axle and bushings.

BTW, the bb's were made in China. Completely disintegrated in the middle of
the season.

LOL! Marshall, not Marshal. And the flow of tools was quite the other
direction.

At that time, everyone no longer thought about making imperial threads.
That "confusion" has ended decades before. At least in Germany.

I've seen socket cap screws the other way 'round - metric threads with
fractional hex sockets. If you order a Huco Oldham coupling (made in
Engalnd) with a fractional inch bore it comes with them. Order a
metric bore and you get regular all metric screws.

I had a '68 Triumph 500 TT... Half BA and half SAE... talk about a bitch to
work on... IIRC *most* of the serious engine parts were BA, for sure the
side case covers were 1/4-20 and a couple of other odd bolts were SAE...

Once, I was detailing a drawing in Autocad, and I downloaded a bearing
drawing file from SKF.

I imported the bearing file into my other drawing, and the bearing
was bigger than my whole assembly! I had to scale it by 1/25.4. ;-)

(rare) American(!) rims, which have metric diameter.

Not just American rims, some european cars have metric diameter rims and
you better check the price of the tyres before you buy the car. Often 3
to 4 times the price of comparably sized inch tyres in the UK. Most
often it can be cheaper here to buy 4 new wheels and tyres in inch size
than to buy 4 metric tyres.


I have heard that the Italian model engine manufacturer Super Tigre
used to use bearings with metric outside diameter and imperial inside

It's one of those "if you need to ask the price, you can't afford it
propositions".

Part of our business (about 300 souls) got sold off to a management buyout.
Because Dassault wouldn't allow 6 licenses to be transferred, a deal was done
whereby the draftsmen still work for us. They are paid for entirely by the
sold off business and only do work for them... go figure.

Yes. As you say, that is the legacy and a useful approximation. The
earth is non-spherical (like a spinning top mated with a potato), and
a minute of arc can vary by up to 60 m in length. Various definitions
existed in the past but the nautical mile is now defined as 1852 m
precisely.

Question: Why do they have a shopping basket on their site when there
is no way to buy their products online? What does Catia cost, anyway?
Just curious.

Something over $16,000 a seat. It is not for the faint of heart, nor the
hobbyist. However, if you're planning to design an airliner (its original
market), it's the way to go.


Um, ouch?

Ever notice how the really expensive stuff, things with commas in
their prices, never seem to be priced online or in print? "Ask for a
quote" is the mark of the "too expensive" set, wot?


Yeah. I had to dig to find the price of a surf fishing reel the other day.
'Turns out it's $599. I had a feeling it was in that "if you have to ask..."
category.


Yeah, people seem to like to bend sportsmen over for fishing and
hunting supplies.

What's even stranger to me is that some of them will pay those prices. That
reel I was looking at was a Shimano Stella, and it's a beautiful piece of
forging and machining. But how much better can it be than a $150 reel? Those
are nice, too. Doubtless they'll cast just as far and they have very good
drags, which are the things you're looking for in a surf reel.

There are a lot of people around with a lot of money, and they'll pay
ridiculous prices to feather their hobbies and pastimes. I'd feel so guilty
I couldn't enjoy my hobby if I spent like that.

I grok you in your entirety there. Now where's that old Zebco reel...?

You will be punished for that. If not now, then in the afterlife...

I'd say save it, but I think ebay has killed the market for collectible
reels. It seems like everybody has some in their attic, and they're dragging
them out to sell because they think they're valuable.

No kidding, I have one that I was offered $200 for fifteen years ago, and
today you can buy all of them you want on ebay for around $25.

Statute miles for visability


Even more strangely, the military opted to give some visibility in
meters.
http://www.bragg.army.mil/www-wx/taf_code.htm

Back in the 70's when I was young and a soldier,
the ranges were measured in meters and distance
was in "clicks". We still used inches and feet
for the smaller stuff.


Knots and nautical miles are based on degrees


Yes. As you say, that is the legacy and a useful approximation. The
earth is non-spherical (like a spinning top mated with a potato), and
a minute of arc can vary by up to 60 m in length. Various definitions
existed in the past but the nautical mile is now defined as 1852 m
precisely.
