Hello,
Our training sites are always on pavement, while our students always setup tripods on dirt, soft substrate.
As you all know, setting up a Fixed Height for beginners, its really beneficial to have a recessed point to stab the Tripod tip into. If you don't, and you can't set the legs, the student becomes frustrated, when the point floats of the point. I've seen two people struggle for 2 minutes with a tripod for the first time - even engineers who are use to Tripod/tribrechs. I strive to make the experience useful, and because we setup in the real world on a set monument, I want to replicate this in training.
The location we train on won't allow drilling a recessed point/brass tag, so that's out.
I was thinking a Washer glued to the pavement would make a nice recessed point to setup on.?
Do you have any tip for teaching Tripod setups on concrete? Hard surfaces?
Just a little dab of 5 minute epoxy would do it without the washer. It would probably be even more convenient, for the students, to put the epoxy on the tips instead of the floor.
How about wrapping the tips with some electrical tape to provide a little more friction?
When I have to set up on a slick floor I usually use what is at hand - wood lath.
Thanks Mark,
Never thought of the tape on tip. Great idea.
I'll be establishing 2 hour OPUS on the points for students to occupy for accuracy evaluation. The washer seems the best thing going.
Trouble is our class is in March, cold surfaces, but the maintenance guys will like this solution over drilling into the parking garage floor. (which they told me no way).

Your problem with the maintenance guys may be your choice of words. Drilling in the floor sounds ominous. You may have better luck if you explain you are going to put "a small nick" in the floor. It does not take much to hold the point. A few taps on a sharp chisel should do it. Or, go with the washer idea.

Ken,
I regrettably said those exact words and it was all downhill from there. Another great tip.
Thanks.

Limit straps around the bottom of the legs are helpful in these situations. They help to prevent the "Bambi" scenario
