Has anyone ever taped a laser pointer to a level?
Seems it should work as long as the pointer has smooth sides.
Just curious after another post on here about them.

Waste of time and would be inaccurate.
Laser levels are no more accurate than bubble or water levels.
Less so in many applications.
Just hi-tech toys for the geekish.
They are good for getting things flat.

My first thought, is that a very tiny shift of the laser, would make for a very large shift at the end of the laser beam.
You'd have to wrap tape tightly, many times around the level, and then you couldn't get the level to sit evenly on the surface you're working.
I don't expect it to work well.

There is no guarantee (or even a claim) that the beam of a laser
pointer is parallel to the smooth sides of the pointer.

accurate either. However, I suspect that over a distance
of , say, 100 feet or less, the problem with either a bullet
or a laser becomes academic.
Besides, it would be a lot of fun......although, if one had

I once helped tape off a huge number of 6' x 10' boxes on a convention
center floor for an event I was volunteering with. The guy that had
done it in years past had two 10' sticks, each with a mark at 6'.
(Basically a story stick) He would lay them on the floor and keep
moving the sticks from box to box as he taped off each area. This
saved him from measuring each box individually, but it still took him
a really long time.
When he asked me to help him one year, I grabbed a laser level and
shot a straight line across the entire floor. We then rolled out a
really, really long length of tape, following the laser line. Once we
had the first line taped, we used his sticks, one at each end of the
line, to help shoot a parallel line 10' away and taped it. Once we
were done with all of the lines that were 10' apart, we rotated 90
degrees and repeated the process every 6'.
Instead of moving the sticks for each box like he had been doing, all
we had to do was use one at each end of the convention hall and shoot
the laser line from one stick to the other. He couldn't believe how
much faster it went, and how even each box came out.

Wrong. Gravity bends space itself, so the lines *will* come out

light rays to a detached observer was proven by seeing the
"jump" of the light from a distant star as it passed near
our sun during an eclipse. The position of the star shifted
abruptly as the light ray followed the bend space coordinates
caused by the sun's gravitational field...... then shifted back
abruptly as the path moved away from the sun. Hence,
the light to a distance observer appeared 'bent".....

found a use for a ruler laser, but I do have a self leveling laser from HF.
I use it in low light. I've measured beam sag, and I built my elevated deck
using that laser. I did try the water hose. It worked ok. Seemed like more
work when looking at multiple points at the same time. I also use the dual
beam HF laser to set angles and dimensions on basement upgrade.

If you take a hose and run it from New York to California and fill it
with water, it will NOT be level due to the roundness of the earth.
Better yet, try going from the North pole to the South pole. I can
guarantee it wont work.

century you would be arrested because a mouse, fly, or bird got killed

terrorist, and would have to face the FBI CIA and Dept of Homeland
Security. They would search the entire construction site for bombs, and
other weapons and explosives. Then a team of psychiatrists would have
to evaluate the shooter, and 20 years of mental health care would be
required after the prison term. In the meantime, all schools, shopping

Home Depot or Harbor Fright are accurate either. I bought one of them,
it was not accurate and I proved it. It had no adjustment. The next
time I tried to use it, it would no longer light up, even with new
batteries. I used it as a regular level for a short time, until I found
out the level itself was not accurate either. Into the trash it went.

On the other hand, we all know that heat rising makes the path
of light waver, as happens when watching a distant object in
the desert or over hot pavement...
Perhaps gravity doesn't actually "bend" space, and it was the hot
air from the sun that made the star jump...... Pehaps Einstein
was wrong........

Gravity isn't going to bend light or space over the range of a typical construction project.

However heat will. Warm air will definitely refract a laser beam enough to throw your measurements off. It's the reason a laser can't be trusted to get tunnels from each end to meet in the middle.
