The legendary PI pie. Somehow I can't picture it tasting good! I ran a sheet metal lay out shop for a couple years. It was amazing how much difference using 3.14159 or 3.1416 made in calculations on something large. I bounced between the two depending on if I needed something to run large or small.

I have known people who knew pi to fifty or sixty decimal places. Definitely limited snob appeal in student circles! I see they have used a supercomputer to calculate pi to 62.8 trillion places and still going! Some little car is a 314. I have seen a few of them with more digits of pi painted across the trunk lid. I had to wonder if that was the main reason they bought the car.

I still get a bad taste in my mouth at the thought of a pi pie!

Somehow I doubt 1/300,000 makes any difference at all in a sheet metal shop. I highly doubt you had the tools to measure that closely, much less cut that closely.

As an engineer, I'd be fired for tolerancing something that closely.

That must have been some big stuff. Or precise. I was amazed at how close 22/7 would get me. If I'm not mistaken, the difference in calculation of a 4' circle using 22/7 instead of pi is 1/16". Measuring with a tape, cutting stuff out by hand, and welding made the difference less than negligible.

Over 1000inches (83.3ft), he is claiming about the thickness of typing paper. I used to work on machines capable of drilling holes within 0.005" in 80ft. Those machines were about five mil each and we used laser trackers that cost a quarter mil each to measure. Even then we needed high level expertise and a damn good plan.

Sheet metal shop? The temperature change would render that accuracy useless.
