Specs that are part English and part metric

According to Roger Shoaf :

And I think that microscope objective threads are typically

Enjoy, DoN.

Mausers have lots of inch pitches on metric diameters. Small ring Mausers barrel thread is 25mmx12tpi. Large rings are 27mmx12tpi. When Mauser first set up, the best screw cutting and threading machines were English, so he bought them and built metric tooling for them.

Autocad is bloatware. :-))

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.

Hear hear, use Catia instead :-)

Eek, the lady on the demo page has one of those whiny, irritating-to-the-core voices.

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.

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.

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.

Even more strangely, the military opted to give some visibility in meters.

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.

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.

Yeah, fishing really is a drag.

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.

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.
