That??s a significant effort when there??s a good chance construction will use 4 or 5 points and RTK. You could get the same usability with an electronic hammer drill, 1/4? and 5/8? bits to set 2 or 2.5? MAG nails instead.
We just use mag nails or 6" ardoch nails. But we haven't done any projects like the ones being mentioned in here. Our points are mostly for horizontal control. And we put them on fire hydrant pads or hydro vaults or curbs, wherever works for line of sight at the time. Most of the time if they get ripped out, anything would have been ripped out.?ÿ

I had to look up ardoch, actually ardox nails. They have a screw-like spiral thread on the shank. In my search, I came upon an interesting piece of nail history courtesy of American Fasteners Co., Ltd.
The penny weight of a nail refers to the price for a hundred nails in 15th century England. The larger the nail, the more "pennies" required to purchase 100 of them. Today, the penny weight is commonly, and many times, incorrectly used to refer to the length of a nail. The symbol for penny weight is "d", from the Latin word "denarius", roughly translated as coin (penny). A 2d (penny) common nail is 1" long. Each 1d (penny) is assumed to be an increase of 1/4" of length up to a 16d (3 1/2"). After 16d, nails jump to 20d (4") and increase in length by 1/2" by multiples of 10 (20d, 30d, 40d etc.) Nails longer than 6", are correctly referred to as "spikes" and identified simply by their length. The penny weight/length is not the same for ALL nails (eg. bulk ??sinker? nails and many gun nails) and they not uniformly employed by all manufacturers. To avoid confusion it is best to call for a nail by the length and diameter.
County BMs must be identifiable and stamped with a letter-number identifier. An example would be S-1065-007 (fictitious), where "S" is the first letter of the last name of the party chief who did the level run, "1065" is the run number, and "007" is the turn number.
Good info. We all call them spikes where I work but I didn't know if that meant anything to people on here. I've never seen an profession where terminology seems to he so completely different from one country to the next.?ÿ
I had never heard of setting "lathe", as we set "stakes". I'd never heard of a "jigga", etc. So many times reading on here I have to google stuff because the word has never come up here in Canada.?ÿ
"lathe", as we set "stakes"
lath = stake
lathe = tool for turning wood or metal to shape
What is a "jigga"?

Lath is made of thin hardwood lumber and is commonly used for surveying. Pine Lath can be special ordered. Some examples of lath include building snow fencing, road construction, road markings, and grading roads. Our lath is available in standard sizes, from 9/16 x 1/18 x 16" to 48" long.
These look more like stakes to me. The laths I used to use were thinner. The stated dimensions don't match the picture.

The image of the lath isn't completely accurate; it's not pointed at either end. I prefer laths for construction staking because you can write a lot of information on the wide sides of them. A downside is that they're a pain to set in hard ground.
@350rocketmike that is a relief:

Yeah, we definitely only use regular wooden stakes, no lathe. For boundary markers we use larger square stakes that are painted.?ÿ
Around here that wedge-shaped stake would be called a bank plug, though I've never used them.?ÿ At the first place I worked all 1x2 stakes (whether 12", 16" or 18" long) were called "cons," short for "construction stake."?ÿ That terminology stuck with me, though I don't know how common it is.?ÿ
And a lath without a point isn't worth having in the truck.
True lath is square on the end and used in construction of lath and plaster walls.?ÿ Tremendously common in old houses.?ÿ Granted, those that have had points cut on them go in MUCH easier.
