Brick, Great sketches on your part but I think we are on different pages. The Laser levels I am familiar with are not the same type.
The types that I see do not mount to a wall.
Laser mounts a lot of carpenters use one of the 3rd Hand adjustable supports:
With a Magnetic Laser Mount:
• A Wall/Ceiling Robotoolz mount that can also be clamped to a structure:
• Or if there is enough room an elevating tripod can be used:
Or a fancier one from Stabila
. The Elevator crank is important to align the beam to structure e.g. a deck ledger board.
One of the problems with using some of the laser mounts is that the lower cost Lasers come with ¼”-11 threads, same as camera tripods while the more expensive mounts tend to have the larger ⅝”-11 thread. Here is a Thread Adapter
As far as using adhesive putty to fasten the Laser to the wall, I do not know anybody that uses putty
for commercial projects.
Reason being that for commercial jobs you need to adjust the laser mount up or down to a specific reference point. Adhesive doesn't have any give.
Some examples of Lasers that are popular now are this one from PLS
And this one from Stabila
Then there is a high end Interior and exterior Laser with a high visibility Green
Beam that is made by CST/Berger
At the other end of the price scale is one from HF that while I haven’t seen it, I know of one contractor that swears by it for non-critical jobs. He said the bubble levels in the Tripod base broke right away so he just does a rough visual alignment to ensure the Laser head is not tilting at an extreme angle, then depends on the Self-Leveling laser to correct for any base misalignment.
