Land Surveyor

As a true Land Surveying / Setting Out engineer I tend to create (Design in CAD and 3D Print & Machining) my own couplers, fittings and fit SMR's and prisms into whatever comes in handy in my Setting Out work.

I bought a limping 2nd hand mini metal lathe end of last year and modified it a bit to suit my CNC idea I have for it. I'm not there yet, DRO's on all axis, working on a CNC solution.

This years intentions (I know, there is a market out there where you can easiy buy stuff but it is more fun to create your own):

- a home made Suction Fit Leica stub with no (0) play (Tick, Done!, see pictures below)

- a Zeiss coupler that fits most tribrach bases with exchangeable 5/8" 11TPI & Leica stub on the top.

- a universal set of couplers: Leica <=> 5/8" 11TPI , Tribrach base to D30.0 mm. SMR

- an Aluminium Setting Out Centralizer MK3 (0.1 mm accuracy) for a D30.0 mm SMR with a light magnet base ring.

See my free own designs on Thinghiverse for 3D printing, 0.5 mm. accuracy:: ttps://

Any more idea's ? Most welcome, certainly if you have a PDF or CAD drawing with dimensions => Get in touch, but keep in mind, this is a hobby of mine, I'm not a production unit and do not intend to compete with businesses out there who have these on the shelf for you: I'm filling a gap.

Wim Janssen van Doorn was a POL Geotechniek (NL) engineer who had solutions before you even realised you had a problem. A true magician in solutions, I learned a truckload from this man

How to use Forums
Our forums on Land Surveyors United are here to be used as much for finding help with problems in the field as the are for you to express your opinions on anything that has to do with land surveying in general. Feel free to share anything that is on your mind, as long as it isn't meant to damage another member's reputation. Please keep it clean and help insure that everyone has the opportunity to enjoy the benefits of being part of a community that grows together.

We are committed to allowing freedom of expression for all of our members, and that includes maintaining a safe space for people with opposing views to express themselves. We get posts from all over the country and even the globe, so needless to say, people come with different viewpoints on lad surveying practices and processes. We see this diversity and variety as a real strength-- dialogue and debate are an integral part of the educational process, as well as an important tool in exploring different sides of complex issues.

All Community Hubs inside the community have their own forum for asking specific questions to other surveyors, by location, equipment type, etc.
