I know somewhere on here someone posted the formula to determine the measurements for labels. For example, a steampunk tube is 1.85 in diameter. You multiply by 3.14 (pi) then there was an additional step...can anyone help?

thanks so much

No need for formulas. True fired way is to take the tube and wrap some masking tape around it. I do 2 layers. Cut with a razor knife and now peel from the tube. Place on a flat surface and now measure the length of the tape. Simple.

John, are you sure your last name isn't "Hardway"?

I am going to have to ask for an explanation. I racked the brains to figure this one out but got nothing. Please explain:smile:

It is a joking reference to your method of determining the diameter of a tube shich seems harder than simply measuring the diameter with calipers and punching a couple of numbers into a calculator.:smile::smile::biggrin:
 
Forgive me Smitty I still not sure if you are kidding or are serious. How is wrapping some tape around a tube harder than trying to remember and figure out a formula. I use that method all the time. Especially if i have a piece of material I want to wrap around a tube such as Carbon fiber. I wrap a small bit of tape on both ends of the tube. Slice in half. Pull the tape off and place on the CF. Do both sides. Now take a straight edge and put on edge of both tape ends and slice. No measuring and it has to fit exact. Could not be any easier than that.

If you are trying to figure measurements out to print decals, measure length of tape using a rule or if have to be precise use your calipers. No math involved at all.

That is an old school method that is older than you are :smile: I have seen people do it with string. Look for some tape or look for the calculator. HMMMM toss up.


I just had a funny vision pass through my head. I can see the insulator on the job site out there with a calculator and calipers trying to figure out how much insulation he needs to wrap each pipe that is different diameters. Hold on boss I got this. 2 divided by 4 times pie now is that apple pie or cherry pie.:biggrin::biggrin: Sorry I could not help myself.

Cherry, made by my mother or sister-in-law.:biggrin::biggrin: I was simply stating the obvious - to be accurate enough you need to measure the tape with calipers...when you cut the tape on the tube you need to make sure that your cut is straight, when you put the tape on the flat surface you need to make sure it does not get a wrinkle in it or it will measure short. I don't know about you but I can do the arithmetic pi x diameter in a couple of seconds even without a calculator.

Now I do use your method myself in lots of situations - either tape or string, but on the job site in your vision it is highly unlikely that the guy would be making his measurement on a little brass tube where he needed thousandths of an inch accuracy.
 
With an engineering background, I tend to lean towards formulas to figure things out, however, simple approaches are usually best. I was trying to lay out some stair risers using trigonometry (you know sine, cosine, opposite over adjacent, etc.) several years ago and was always off by a 1/4 inch or so at the end. I just could not measure precisely enough using the higher math. I knew that carpenters were able to do it using a framing square and after playing around a bit with the square I figured out how it was done, laid out my risers, cut them and they fit perfectly. Since then, I am a firm believer in the kiss principle.

They did the math for you when they laid out the square.
 
Well Smitty I just threw that option out there. You make my method sound like there are a ton of variables. It really is as simple as you could possibly get. Use it don't use it is fine with me. I will use it every single time I need to wrap something around a tube. never will I use the PI formula. Hey that is just me. I am from the KISS school of thought. Graduated with a degree.:biggrin:

I told you that I do use your method at times. There are a ton of variables if (for instance) when you cut the tape off the tube and your cut is not dead straight and you measure the tape anywhere but the longest side, you'll be off, maybe not by much (depending on how far off 90 degrees you are from the edge) but you'll be off. And, whether your method is simpler (KISS) in pen tube measuring is a matter of opinion. Me I graduated from the "School of Hard Knocks" 20 years before I got my college degree.:smile:
