No math, just a guess. A little over 3 feet. How close am I?Geeze, some experts that don't know diddly! I never said I was cutting to that, I said I used those numbers to do the math. As for mattering one of my last projects in the sheet metal shop, I cut material for a storage tank 3000' around and the pipes going around the outside of it. For the math geeks, how high will a pipe be in the air if it goes around the world at the equator and you add one extra twenty feet long joint of pipe? Surely an extra twenty feet at the equator wouldn't matter much would it?
Since there is talk of tolerances, that is one of the first things I straightened out when I was hired at the local nuke to check all drawings from the drafting department except my own. One of the first drawings I saw was a bracket for a pipe hanger, dimensioned to four decimal places! It is debatable what tolerances are when none are listed and a friend was an expert witness in a case arguing just that. However, rule of thumb is one of the last digit so somebody could have somewhat reasonably cut those brackets to one/ten-thousandth of an inch and charged a ton for them at cost plus! A half inch tolerance was plenty tight for those brackets.
Working for the R&D company on the project before going to the nuke we built several versions of a roughly one cubic inch freon compressor. There dimensions were to a tenth as we commonly called ten-thousandths and the tolerances were one fourth that! Fun times but when I spent some time cutting in the neighboring short run production machine shop there were no tolerances on the drawings. Without thinking I asked him if a few tenths were good. He said that would be a bit sloppy and I realized my error. A few thousandths, even a hundredth was OK. Tenths of an inch would be getting sloppy. It was kinda fun hacking out parts after having to reject components because somebody polished one or made an extra spring pass.
To give some idea how tough it is dealing to tenths, I sent a request for bids to forty machine shops. Only two said they could do the job when I just told them verbally that components outside tolerances would be rejected. When I sent them drawings with the same statement on them the last two quickly rejected my request. I was in Louisiana and ended up doing business with a shop on the east coast and one on the west coast.
In my many positions over the years I have ran sheet metal fab shops, metal fab shops, and machine shops. As already obvious, I have been the liaison with and over machine and specialty shops. I have also cut to dimensions that couldn't be measured, they had to be gaged at a certain temperature. Micro-machining before NC was fun but it was a good way to get gray hair or bald in a hurry!
Design work in general was a blast. I got paid for staring out the window. Four days a week nobody could tell if I was working my ass off or thinking about the fishing trip that weekend. Friday after lunch there was no doubt. If there wasn't an emergency to deal with I was planning the stops on my weekend fishing trips. I got my bosses so well trained they would apologize if they brought me something to deal with on a Friday afternoon!

You’re absolutely right.i apologize for not reading past posts but i think these type of discussions belong in NPR
they are not memes or gifs or funny

AcceptedYou’re absolutely right.
I never even noticed that this was the forum in which @Chili Palmer made the initial post to which I was responding.
My apologies.

Lol, I remember some lady coming in and getting $1 at the full service pump. Gas was around $1 then and she drove a big Buick. Maybe she got home, maybe she didn’t.
How close? Pretty damn! I'd call that an educated guess. Most folks guess a lot less than an inch. There isn't nearly the margin for error that some people think exists.
We kept up with the biggest sale ever in a car at a Mobil station. A big Pontiac ran out of gas as it turned in the station. Filled it up then jumped up and down on the bumper to pack more in! The owner finally had enough and made us quit. A new record, 26.9 gallons of premium, came to $9.35!
I used to brag about my Suburban. I got over six hundred miles to the tankful. Mine was a two wheel drive with a 350 engine. Some came equipped with four wheel drive and a 454. You could watch the gas gage falling as you drove. Before the gubment regulated the size of gas tanks mine had a 49 gallon tank from the factory. I didn't always mention that little detail when bragging about how far I went on a tank of gas. It really was very nice traveling.

I had a couple of those Suburbans with 454 gas engines in the 90's. 3/4 ton chasis, 4WD, really good on the highway and turns, stiff suspension. No idea what my gas mileage was, so obviously it was not a concern. Just ordered a GMC 2500 HD 4WD with 6.6L gasoline. Dealer offered to 'let me off the hook' and keep it on the lot when it gets here. No way.How close? Pretty damn! I'd call that an educated guess. Most folks guess a lot less than an inch.

hell is what this thread is turning intoHELL EXPLAINED BY CHEMISTRY STUDENT
The following is an actual question given on a University of Washington chemistry mid term.
The answer by one student was so 'profound' that the professor shared it with colleagues, via the Internet, which, of course, is why we now have the pleasure of enjoying it as well:
Bonus Question: Is Hell exothermic (gives off heat) or endothermic (absorbs heat)?
Most of the students wrote proofs of their beliefs using Boyle 's Law (gas cools when it expands and heats when it is compressed) or some variant.One student, however, wrote the following:
First, we need to know how the mass of Hell is changing in time. So we need to know the rate at which souls are moving into Hell and the rate at which they are leaving. I think that we can safely assume that once a soul gets to Hell, it will not leave. Therefore, no souls are leaving.. As for how many souls are entering Hell, let's look at the different religions that exist in the world today.
Most of these religions state that if you are not a member of their religion, you will go to Hell. Since there are more than one of these religions and since people do not belong to more than one religion, we can project that all souls go to Hell.
With birth and death rates as they are, we can expect the number of souls in Hell to increase exponentially. Now, we look at the rate of change of the volume in Hell because Boyle 's Law states that in order for the temperature and pressure in Hell to stay the same, the volume of Hell has to expand proportionately as souls are added.
This gives two possibilities:
1. If Hell is expanding at a slower rate than the rate at which souls enter Hell, then the temperature and pressure in Hell will increase until all Hell breaks loose.
2.. If Hell is expanding at a rate faster than the increase of souls in Hell, then the temperature and pressure will drop until Hell freezes over.
So which is it?
If we accept the postulate given to me by Teresa during my Freshman year that, 'It will be a cold day in Hell before I sleep with you,' and take into account the fact that I slept with her last night, then number two must be true, and thus I am sure that Hell is exothermic and has already frozen over! The corollary of this theory is that since Hell has frozen over, it follows that it is not accepting any more souls and is therefore, extinct......leaving only Heaven, thereby proving the existence of a Divine Being which explains why, last night, Teresa kept shouting 'Oh my God.'
