How many times have you asked that question or even ask yourself because you forgot to measure or write down the answer?
Does anybody carry a diameter caliper? If one that was convenient to carry and was available, would you? I have an idea for making one.

I got these for all of the truck key chains, the ones I got were silver not black.

Those are cool, but kinda hard to measure a 6" bollard with. That, and the keys are usually in the truck a thousand feet away.
That's a pretty handy tool.
My guys seem to have a hard time determining the "nominal" size of rebar. I understand it can be difficult when they've been smacked about and there's only a bit of it that is exposed. My simplistic answer is I keep three size of plastic caps in the truck with their size magic-markered on the side; 3/8", 1/2" and 5/8". They use those as a gauge when describing rebars. I make them measure pipes and bars with a tape.
Another funny thing I see on collection files is "40d nail in PP" or "60d nail in PP". I always ask them how they can tell....a 40 penny and 60 penny have the same size head...only the shaft is different. You really CAN'T tell if it's in a pole.
I bought all my crews "diameter tapes" for measuring line sizes. Basically an inch is 3.14159... inches long. I would think most any engineering supply store would have (or can get) them. Small enough to carry in the pocket of your vest.

Looks like 3/4' to me!
I have used the little plastic calipers before for smaller dimensions. I like loggers tapes but rarely use the diameter feature, usually opting to eyeball or eyeball with a pocket tape.
A folding rule has been in my vest from day one.
Every survey crew has so many tools that measure and it amazes me at the excuses people come up with why they didn't know what size something is.
It is because they never actually measured it and/or worked for someone that didn't do it either. Some people must have it drilled into them by force. Also amazing is why some guy thinks it is 1/4 inch and another swears it is 3/8 inch and so on up the scale.
Like breathing, there are some things that after a few million time we can start to do in our sleep......
Personally, I look at it and give it a size in units. # for rebar and inches for pipe and that gets turned into something final in the office that may resemble that of record if I am certain it is the same hunk of iron or whatever and the measurement is off a little
Consistency is important with such things.
B-)
Those are cool, but kinda hard to measure a 6" bollard with.
I agree it only goes up to 2 inches, it for pipe and rebar. If we need to measure a bollard, we will just go back to the truck and get a tape measure. Also if we are doing alot of culverts, we will just get a lath and mark it, 12 inches, 15, 18, and so on. Saves some time and helps if the culvert has alot of trash or slit in it.
Slit happens!:-D
I'm an eyeballin' sorta guy. I'm that bad example you can refer to when you admonish your workers for not being laboratory precise on everything. Somehow, it has never come back to bite me in the derriere over nearly 40 years of opportunity.

We all seem to be able to tell if it's a #3, #5, #7 rebar, or 1-1/2", 2", 2-1/2", 3" cap, the Iron Pipes are a usually measured with a tape. I've also never been admonished because of saying it's a 2" cap when it's a 2-1/2" cap, really what's going to happen to you?
My thought was a tool that will not be an inconvenience to carry. Something no bigger than 8" long that will fit in your pocket or tool pouch when folded up. It could also be attached somehow to the prism pole, making it handy at all times. There would never be an excuse good enough for not checking the sizes again.
That is the idea. Is it a good and valuable idea?

The tool I posted a link on is a Key chain, its not the best pic, you can not really see that it has a 0 to 2 inch ruler on the top of it, they also have small tape measure that are round that measure for up to 6 feet or so, those seem to break alot, you can even order those in your company name.

I'm overly pedantic. If it is a 5/8" rebar, it does not get called a 1/2" rebar. HOWEVER.....
I have a few plats out there, with 9/16" rebar on them. I suspect they are a rusted down 5/8" rebar..... Do they even make 9/16" rebar?
It took me a while to figure out that Pipe sizes are in reference to the ID, not OD. I have field books with both ID and OD.
We are SURVEYORS. We MEASURE things. Not Estimate them!

Nate,
I can picture Big Help explaining "My Daddy is pendatic...but we are praying for him..."
Picture Lt. Higgins explaining the oath Surveyors make...

Have this hanging for ready reference....that tool should come in handy
I have had SEVERAL instances where my crews come in with a shot that says "found iron pipe". And I'll ask, "what size was it?". "Oh, they were all 3/4 or 1/2, if you need to know on a specific pipe, let me know."
Then, I slap them twice and calmly say, "I need to know the size on EVERY monument you find. Also, whether or not it was tagged, if it was, what the tag number is, if it is in a monument well or not, set in concrete, if it was at grade or below or even sticking up, if it was it bent or leaning or otherwise disturbed, if the top was damaged, if it was right next to a post or wall, if you had to dig through the asphalt to find it, and I need you to take a picture of the monument once you had it exposed."
I do this every time for every monument. Unfortunately, I'm not the one in charge of hiring/firing field personnel otherwise we'd have different field practices. When I worked out in the field, I was required to carry all kinds of things in my pouch so that when I dug up a monument, I could get a full description of it. I had a small wire brush, a very strong spoon to scrape dirt from around rotting wood posts, wire cutters and some replacement wire so I could remove a brass tag to read it and then replace it, a mirror to reflect light down a hold I had dug around a monument, and so on. This was just expected of me. Now, the crew will expose just the top of a monument enough to get a shot and call it "found monument".
I've had some map reviewers question my description of a monument size before. I had called out a 2 inch aluminum cap on one map and had the map checker comment that "the original map set 2-1/4" aluminum cap on 1-1/2" iron pipe set in concrete". I had to explain that the "set in concrete" part made it impossible for me to see the 1-1/2" iron pipe underneath the aluminum cap AND that when pouring that concrete, they recessed the monument such that measured as only 2 inches". I do as little work as possible in that community now...

I believe your dimensions on the 1 1/4" pipe are in error. It should be 1.66" O.D..
I would never right down the nominal size (if you measure the O.D. then write that measurement down). I have also gotten away from writing down the rebar number. (If I actually saw the number on the rebar I would state it. The size of what I find is what I measure it to be. If its rusted-down rebar, I might note that, but I might say 9/16th measured at the top (?).
I have even seen guys find old original stones and written down the size that was written in the original notes. You don't know how long it is unless you dig down to the bottom of it, and you seldom get the same exact size as was written down in the notes either. It might be that it measures different on the top than when they measured the middle of it when they set it...I don't know.
When I was a newer rodman on a crew I found a monument we were looking for in the woods and wrote down how the cap was stamped. It had an upside down digit and I sketched the cap and wrote the number upside down as it was stamped. I was admonished by my party chief who thought I should write what they meant to stamp it. I disagree, it actually shows that you found the cap in the field, and someone following in your footsteps knows that they found the same thing (or not).
