Yes, Home Depot stocks just what I need...:clap:

How do you catch a unique rabbit?

How do you catch a tame rabbit?
The tame way -- unique up on him.
A number of years ago when I was a goobermint employee we had a specific system to number our PLSS corners.
They were all 9000 series numbers. Next (after the 9) came the section number...and then we started at the center of section with number "1" and went clockwise around the SW/4.
Of course all the other corners in that specific section were numbered out of other sections:
You could easily look at a six or seven thousand point printout and find your section corners. The only glitch was if the project was over six miles long in any cardinal direction...
Every job I do gets unique point ID's and those get stamped on the cap.
yy-jjj-nnn where that is year-job-point number. If you find one of my caps in the field and call me, I can find the info within minutes.
The first point in the first job in 2013 will be 13-001-001, the dashes are optional if your software doesn't support.
If I tie an old point on a new job, I use the original point ID, the days of starting every job with point 1, 100, 1000 or whatever are over for me and have been since 1995 when I started my own business.
I use the same numbers in the office, field, notes, whatever, I won't repeat a point ID for 100 years and by then I won't care!

You're a resourceful fellow, Shelby. Do you have a special stamp to strike the whole point ID in one go, or do you have to stamp all eight numbers individually as I would have to do?

Nope, I am no different than you in this respect, must stamp it all out!
If I am working on a larger project where I am going to for sure have 20-30 or more mons, I will order them semi pre-stamped with the year and project portion of the ID such as "13-001-", just have to stamp the point number on the cap.
I have had no issue ordering small batches of caps from Mark It in Tucson, AZ. They don't charge a setup fee, so this is a good way to go on larger projects, saves some time.

We use a similar system for our control (habit from the years of USACE work) where our control is named Book/Page. For example, if the crew is using book number 1185 on page 17, the first control point established and noted on that page is 1185/17. If other control is established on the same page, it gets a letter (1185/17a).
I was pondering something like Shelby was discussing. But here our some of the constraints I'm faced with.
For a normal project- one that is going throught the entire design process, a project control number is assigned well in advance of any field work. Our Standard is that all control points will be numbered Alpha numeric from the beginning of the project to the end- ie. project control number 7773 would start with A7773, B7773,....etc. do not use I or O. so if there are more than 24 control points on the project... AA7773, AB7773, AC7773, etc.Ariel tgts are 600-699, so their point no.s are 7773600, 7773601, etc.
Cadastral/ controlling property corners are 100-199, so 7773100, 7773101.....
property corner monuments are 200-599, 700-2000... so the standard pretty much works for -standard projects, although, you don't necessarily know what vintage the control is on on a given project by looking at a point number. Is it intial control or secondary densification, etc. dates are stamped on the caps, but sometimes that isn't noted in recovery field notes.
The standard falls apart when we start working on overhead projects. We call them "4000" projects since that is the overhead charge number. These range in scope from maintenance requests for roadwy issues like slides, culvert failures, etc to r/w encroachment, excess land surveys, maint. site developement.
Currently - we just use A4000, B4000, C4000 - but as you can imagine there are alot of "A4000" control points scattered around the 13 counties I work in...
Other considerations -
Survey pro will let you intermix alpha numeric, Geopak wont. A4000 is good 4000A is bad.
stamping and point naming for points submitted to OPUS-DB.
99% of our current work is in state plane- international feet- legacy projects are a mix of the sordid past....
Keyed to Monument List
I was surveying the Paint Mare ranch a few miles north of Dryden about 9 years ago and came across several "McMillan" Caps. I looked you up and gave you a call. You had a point list to me within the day. Great job! :good:
I like the unique point numbering concept; wish I had thought of that back in 1995 when I started on my own.
So, am I too old to start???? There would be lots of "point skeletons" in my closet; how would you (or would you) rectify old jobs?

I'm thinking there's some room for making a fixture that will hold all nine dies in a low-tech press to stamp caps and washers. You'd need to change out one digit, but it would be fairly light work to stamp fifty caps or washers with the multi-digit i.d. number using the right fixture to hold all the dies.
Since most of my stamped washers are two digit i.d. nos. and boundary markers usually three, it's easy enough to stamp them in the field as they are used. For a large job, I'd think some shop stamping would probably be worth doing if one is going to use long i.d. nos.
Stamp for Long Point I.D. Nos.
This unit looks expensive, but for stamping lots of caps and washers with long numbers, it might pay for itself. No alpha on this one, though.
Probably two five-digit stamps would work better than one nine-digit stamp since half the force would be needed to do the stamping and, since the first five digits would be repeated on a whole series of caps or washers, the time that would get eaten up would mainly be in advancing the number for the last part of the pt. i.d.
A Better Stamp for Long Point I.D. Nos.
This one looks even better and looks as if it ought to be cheaper.

Oh, that looks like an item every State DOT will want to buy out of petty cash. I was thinking about getting a frame made that would hold the dies and grinding them to the same length so that a hammer blow would catch them all. That's the private sector solution. :>
