The boss does pretty good. 54 setups in less than 7 hours using tall stakes for traversing and 2 man crew. Made is almost all the way around 140 acres of grown up clearcut.
Bruce Springsteen is a surveyor?
Thats rockin, hows the closure?

Is that setup?
Backsight a tack?
Maybe a tie into a fence or post with a hand tape and then move ahead?
That's pretty good. Not sure how many I could do in my prime, but it always seems that there was other stuff to get.

Out here in God's country 54 set ups might cover about 27 miles. I'd be far too tired to post about it.
:good:
I took that to mean that he set his backsights with a tall stake as it was only a two man crew and it would have worn out the other guy giving fore and back sights. We used to put a line on a four foot stake and extend the mark to the top where it could be seen in the optical plumb. By carefully driving in the stake then fine tuning it by pounding the ground around the stake it could be positioned right over the nail suitable for a backsight (just don't hit it with the legs when you pick up your gun).
Oh yeah, I knew what he meant. 🙂
I guess I had it talked through in my head rather than explaining it very well. I think they use thigh cut stumps with smaller nails for their backsights and make sure the forward guy can see the stump. I know a company that uses nails set flush for traverse, and then they use 4' lath with a tack in the top as a backsight. The I-man sets the lath before he breaks down. I've done it a few times so as to not wear out the forward man/men that were cutting line with blades and chainsaws. Gotta use every trick in the book sometimes. 😉
I use a 4' lath about 6-10 feet away from the instrument (front or back) on line with the frontsight with a finishing nail and folded flagging. Usually works great but cattle or horses will play with it. Never used it the next day without checking.
So, Ted is back?
OK OK, I'm just kidding you!
Tall stakes will really eat a long traverse.

Wow - 7 min 48 sec average per set up - I'm impressed!

No traverse points in the ground (except where we expect to go back to set pins) , the traverse points are 8P nails in the top of 4' stakes or cut-off trees. Rod man never has to go back for a backsight.
This job had few sideshots, probably an average of one per setup.
Closure is TBD. Will finish the remaining stations Friday.

What he's not telling you, is the SETUP time, to go and cut off all those small trees, place the 8d in to top, and to set lath, with the same. This is the instrument time, to run a well laid out traverse. One day, I took a chain saw, and cut around 40 acres, 1320 + - per side, and cut off trees, and made stakes, and traversed around it all, solo in a day. Closure was about 0.08', and 12" in the angles. My point is, that when laid out right, it works well.
I like laser plummets too. At some locations, you can set a kink in the nail, so that it comes up out of the stake, goes over 90° for 1" , then back plumb, and that last bit of plumb nail is the point. Now, while set up over it, you spin the nail out of the way, drop a nail to the ground, and then spin it back. Laser plummet is the ONLY way to go on this. Optical plummet cannot focus on a point 1-4" below the tribrach, and bell housing.
This kind of work, requires you to think about stuff in advance, and it works well. I will add, placing a nail in a tree, to shoot to, for a site is handy too. Like, you are done on friday, and you drop a nail below a tall stake, (like I said above) and shoot a nail in a tree, (random location) and now you have a nail and backsite for later.
