Back in the 1970s, the company I was working for, being international, decided all designs were to be metric. A design I was creating required various stainless tubing sizes, one being 10mm in diameter . Orders went out for 100mm lengths. A few weeks later a couple of large tractor trailers showed up at the receiving dock. Yep. Seems the vendors were not quite yet on board with metric sizing; all the tubing was in inches. Not sure who ate that one or what happened to the tubing but we just could not get any of it to fit into our typewriter designs.They probably wanted to make it dual Metric/English units and figured they would round it off to 40 inches.
A few decades back the USAF realized that they were using torque wrenches with dual SAE and Metric calibrations and it was very easy to read the wrong scale. So they got rid of all torque wrenches with dual calibrations.
Now you're cooking!
Cheech and Chong. Ohh the laughs i had with these guys.
'metric' tubing/pipe is generally only nominally metric.Back in the 1970s, the company I was working for, being international, decided all designs were to be metric.

I guess we know which one is the b!tch.
'metric' tubing/pipe is generally only nominally metric.
i.e. 6mm pipe is actually 1/4", 50mm pipe is really 2"
Unless you're working on a purely European design, its almost impossible to get hold of.
We had a Fouga Magister that needed new brake lines fitted, that were proper 6mm line, and everyone who said they had 6mm copper pipe, when measured, found it to be 6.25mm.
The only place we could find it was FranceOnly metric tubing made to ANZ (Australian and New Zealand) standards.
The stuff I have bought from the USA is real metric.

| Someone asked the other day,,,,,,,,,,,,, 'What was your favorite fast food when you were growing up?' 'We didn't have fast food when I was growing up, I informed him, ' All the food was slow .' 'C'mon, seriously. Where did you eat?' 'It was a place called 'at home,' I explained! 'Mom cooked every day and when Dad got home from work,we sat down together at the dining room table, & if I didn't like what she put on my plate, I was allowed to sit there until I did like it.' By this time, the guy was laughing so hard I was afraid he was going to suffer serious internal damage, so I didn't tell him the part about how I had to have permission to leave the table. Here are some other things I would have told him about my childhood, if I figured his system could have handled it: Some parents NEVER owned their own house, wore Levis, set foot on a golf course, traveled out of the country or had a credit card. My parents never drove me to school. I had a bicycle that weighed probably 50 pounds, and only had one speed, (slow). We didn't have a television in our house until I was 10. It was, of course, black and white, and the station went off the air at 11:00 p.m., after playing the national anthem and a poem about God. It came back on the air at about 6:00 a.m. And there was usually a locally produced news and farm show on, featuring local people ... I never had a telephone in my room. Our only phone was on a party line. Before you could dial, you had to listen and make sure some people you didn't know weren't already using the line. Pizzas were not delivered to our home... But milk was & so was bread. All newspapers were delivered by boys and all boys delivered newspapers -- my brother delivered a newspaper, six days a week. He had to get up at 5 AM every morning . Movie stars kissed with their mouths shut. At least, they did in the movies! There were no movie ratings because all movies were responsibly produced for everyone to enjoy viewing, without profanity or violence or most anything offensive. If you grew up in a generation before there was fast food, you may want to share some of these memories with your children or grandchildren. Don't blame me if they bust their gut laughing. Growing up isn't what it used to be, is it? MEMORIES: My Dad is cleaning out my grandmother's house (she died in December) and he brought me an old Royal Crown Cola bottle. In the bottle top was a stopper with a bunch of holes in it. I knew immediately what it was, but my daughter had no idea. She thought they had tried to make it a salt shaker or something. I knew it as the bottle that sat on the end of the ironing board to 'sprinkle' clothes with because we didn't have steam irons. Man, I am old. How many do you remember : Head lights dimmer switches on the floor. Ignition switches on the dashboard . Pant leg clips for bicycles without chain guards . Soldering irons you heat on a gas burner . Using hand signals for cars without turn signals . Older Than Dirt Quiz: Count all the ones that you remember, NOT the ones you were told about ! Ratings at the bottom. 1. Candy cigarettes 2. Coffee shops with table side juke boxes 3. Home milk delivery in glass bottles 4. Party lines on the telephones 5. Newsreels before the movie 6. TV test patterns that came on at night after the last show and were there until TV shows started again in the morning. (Only 3 channels! If you had a TV!) 7. Pea-shooters 8. Howdy Doody 9. 45 RPM records 10. 78 rpm records 11. Hi-fi records 33 1/3 rpm 12. Metal ice trays with lever 13. Blue flashbulb 14. Cork popguns 15. Studebakers 16. Wash tub wringers If you remembered 0-3 = You're still young If you remembered 3-6 = You are getting older If you remembered 7-10 = Don't tell your age, & If you remembered 11-16 = You're older than dirt! THAT'S ME! I might be older than dirt, but those memories are some of the best parts of my life. Don't forget to pass this along! Especially to all your really OLD friends |
