Aloha, just recently we got several control point setup--35 of them. Thanks to many of you who guided me to successfully completing this step. One suggestion to set a tall pole that inter visible was extremely helpful for this project.
We used 3' section of old PVC pipe. Filled it with concrete. Then inserted a Gin pin with survey marker. Let is set for few day. Drilled hole in the ground and pound the tubes in. It looks awesome!
The dimples in many of the Gin are a bit deeper. I may need to fill them a bit. Only realized it after I stand a prism pole on one couple days ago.
Thank you again for all of you for your generosity sharing your knowledge and wisdom!
Nice monuments that could use lead plugs.
Nice work! Looks very professionally done.
What is that livestock in the picture with the atv?
From your avatar image, it looks like you are ready to perform some solar observations on your new control stations,
A job well done. Keep up the good work.
Those look great! Someday someone will be recovering these and silently thanking you for setting durable monuments.
:good:

haha....so that's why he was asking about refraction earlier....better wait for the sun to get a little higher above the horizon, and don't look directly through the scope without a solar prism or filter....B-)
Great work. Thanks for sharing.
I truly enjoy my job (hobby) too, ... usually.

Nice job. I've used many cotton spindles for control points in the Texas hill country. I've found that there is a natural low point in those things. I'm surprised to see that those spindles were shipped to Hawaii. Seems like it would be a high cost to do that. I would have thought you could have used mag nails as a cheaper alternative. But then again the shipping on those might be not worth it as well. It would help if you didn't live on a volcano for prices, but the scenery wouldn't be the same. 😀
How did you manage to drill out the tops of those spindles? In my thinking, they are very hard metal, and would require some SERIOUS clamping, drill press, and maybe some broken drill bits!
Are they only control, or are they for corners?
Thanks for sharing the pics.

Aloha, Spledeus:
That's good idea! Thanks

Aloha, Robert:
Thanks!
Those are our three Jerseys and a Holstein milking cows. We have five of them here--one more Holstein in not in the picture. Then we have another four in our retirement pasture--15 acres or so. The older cows live there until their last day on Earth.
I was just messing around on Photoshop the other day and made the avatar. I am still digesting C&R so it might be awhile before I can do solar observation;-) Lease Square Adjustment is my next item on the study list.
Thanks Alan!
Aloha, Jerry: Thanks!
As Nate's signature says "Surveying is more than a Job----it is a passion to provide a foundation for future generation, that is beyond reproach."
Hopefully, it will be there for many, many years!

Aloha, Tom:
I thought the rising Sun is easier on the eyes 😛 If I were to do it in the future will be very careful. Probably won't do it until posting here for details first. 🙂

Aloha, Steven:
Everything is expensive when shipped to Hawaii! We don't ship heavy items directly to us unless it is free shipping:-D We have freight forwarder that consolidate all shipments in California. The downside is sometimes you have to wait about a month. So we plan ahead and it is generally work out perfect.
I thought about various options but decided to go with cotton spindles. I thought it will give a distinct look to the monument. Hope someone think twice before messing around with it.
The island we live Kauai is the oldest of the island chains. So no active volcanos. 🙂 It is an awesome place!

Aloha, Nate:
They actually have a natural dimple in them. I've never seen how cotton spindle functions. But looking at it...I think the depth of the dimple varies, that could the cause of them being replaced.
These were controls. Corners were set with 1/2" iron pipe by my PLS. I follow what you all suggest!:-)

Yes, if you consider doing it, please post her first. You do not want to have an accident wit a very expensive instrument....besides your survey instrument...your eyes.
Thanks for the reply.
Yes Least squares and solar observation are very good math calisthenics for the surveyor.
solar observations will ties your surveys to the cosmos wich in a metaphysical sense may intrigue you.
Least squares will connect you to Gauss and control surveys of yesteryear Europe.
