1/10th of an inch huh?

I've just spent 10 years dealing with the nonsense that is American/Imperial inches - 1/16", 1/8" and so on. I have become quite fluent in that and with millimetres. Now i'm supposed to deal with decimal inches am i?

I hope you never buy shoes that fit!

Lol... .1" =2.5mm or 1/4 of a centimeter or 1/125th of a foot, 1/375th of yard..... I can go on... 2500 micrometers.. 2.5million picometers or 2.5x106pico.....

better?

I shall for posterity just define a cricket pitch as 22 yards of grassland where the English get their arses handed to them.

It's also my opinion that only Puppy uses 10ths of an inch - i have never heard anyone else say so :)

How long did that last? 'Far too short - was 4/10ths of a minute' :blink:

Then you've never spent time around machinists. tenths, hundredths, thousandths and ten thousandths are the norm.


Granted, I wouldn't have said a tenth, I'd have said 100 thousandths. Same measurement, just more used to thousandths.

:laugh: you guys are a riot. I had a 6 inch scale in my pocket and did a quick measurement. One side of the scale (metal ruler) had inches with marks in tenth's and hundredth's, the other side 32nd's and 64th's.

If I had been at home I would have used my digital calipers. In that case I would have preferred thousandths.

Hey BB, welcome back! Right now is a little under a month turnarounds. . . I've got two mills going full time, knocking or mods a bit faster. .
I'm doing everything except for titanium, to do titanium I have to have the holes started by am EDM, adds $80/hole so they are post much priced out of existence. If you want a titanium mod I can build you one out of 7075 aluminum instead, chowder and a few others have them, it's lighter than titanium as well.

If you really want I can hit the corners. I don't recommend it, I don't think it looks good, but if you want it I can do it.

is that a standard option now? i think ch had to hunt down his own metal

US manufacturing, especially machining operations, have been using fractional inches forever. Most use machine tooling is geared around the fractional inch (calipers, micrometers, mills etc.).
A tenth is uncommon though isn't it?

I agree, but what i am hinting at in a roundabout kind of way is that if you start using tenths of an inch as an arbitrary measure, you may as well just use a metric system of measurement and be done with it.

I've heard the parties they hold are a a riot. But once more you are neglecting to mention the units you are measuring. Inches, feet, IQ, spaghetti.

Well the same units as in the quote. Not arbitrary. If I had change units then I would have started the change.
You were talking about inches so I continued.

I'd also add that nearly all machinists in the US would default to inches in discussions.
So if a unit is not given, it's inches.

It's always been decimal inches for high tolerance. I have seen some prints from the 50s with fractions, but always with a larger tolerance.
So 1/4" would be treated differently than 0.25" or 0.250"

But you seldom ever see decimal inches outside of machining.

Agreed! I use nothing but metric in my atty endeavors.

Sorry I haven't been around a lot, Tapatalk is Killin me. .

Let me clear the air a lil. You guys should know that xpup is pretty much always right, chickens or yardsticks.
The cap of the mod is half inch or five hundred thousandths . . The buttons come up from the bottom, six hundred and fifty thousandths or seven hundred and fifty thousandths tall total (Short or regular height ). I used to do tall, reg or short but I'm pretty much just going w short and regular now. Short buttons are one hundred and fifty thousandths above the deck, about fifty thousandths, when depressed, above the deck.

:blink:

so how far away is the top of the driptip from the arch of my eyebrow?

Oh and where's my mod?

T
Depends on the drip tip! I figured you knew you were on deck that's why you've been hanging out lately! I cut your mod out of the bar today, tapped the holes for the top screws and cut the top. Good timing there bro.

For God's sake man - i'm struggling to get HRH to read a normal American tape measure, let alone one in tenths of an inch!

Beware of the ones marked in 100ths then ;)

There's always decimal time Decimal time - Wikipedia, the free encyclopedia
10hours a day, 100 minutes/hour, and 100 seconds per minute.
Or maybe Swatch's Internet Time, with 1000 beat per day (1 beat = 1min 26.4 seconds an 1 centibeat - 0.864 seconds)

But, the human mind works better with duodecimal (base 12) and sexagesimal (base 60).
1/2, 1/3 and 1/4 are common fractions encountered and work much better with those bases versus base 10.

I find it an interesting subject to explore and explains the use of 12s and 60s in many measurements.

That's fascinating and HRH is particularly interested in decimal time because we will both sound younger :laugh:

Naturally, she will be at most 35 and i shall be on my death bed!

The pictures posted of them being made is really why i hang out here, i admire the skill it takes to produce something like that. It's not just that i am impatient and greedy. Much.
