Thank you Everyone for all of your knowledge! This Super helps!
My new set up, Thank you, EVERYONE!
Great! What is your initial impression of the new legs?
"I stopped using Tri-Max for anything other than GNSS or radios, years ago because was constantly out on back site checks as the weather changed. The coefficient of expansion plays a lot into the issue. Not to sound like a salesman but the Leica GS120-9 legs. The Tri-Max work well if the conditions are constant."
I experienced that too, fibreglass tripods move. I installed dual clamps on the GS120 for some extra rigidity, and I tighten torque the bolts clamping the leg pin bushes at the tripod head. I've broken the bush retaining clamps on the Tri-Max when tightening them, I haven't broken any on the GS120.
Tribrach's have three levelling screws, the old Y levels and transits had four, this was so the elevation didn't change when adjusting level. When adjusting two levelling screws in opposite directions, the height won't change, so adjust half on one side, then the remaining half on the opposite site to bring the tribrach level without changing height. Provided you don't change the height, if levelling the tribrach over the point returns it to centre, you're back in the original position. If however it doesn't return to centre over the point, then you'll need to re-centre the tribrach, to return it to its original position, in this case it's inevitable that the tribrach will be rotated slightly and you'll need to re-setup the instrument. Always check the back sight after making any minor adjustments.
Legs feel good! much lighter than the other tripod I showed you
Thank you
One more new item I got!
How are they doing in the heat?
Hope it's all insured! Can see some dummy grabbing some rebar next to it. 🤡
Doint better with temp changes, and yes they are insured
There is rarely any place on a construction site that isn't perilous. Luckily, bundles of rebar don't just jump up and smack your setup. Generally, there will be some buildup to it. Keep you head on a swivel at all times.
I don't think we should besmirch the entire trade of reinforcing iron workers.
(That being said I once had my station grazed by bar that was being packed by on someone's shoulder. 😅)
