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.

True, but if you took the time calibrate it (ie, insure the beam is
parallel) with some other level, it should work. Of course, you have
to account for the width of the bubble level it is attached to - eg,
the dot will appear 2" higher than level if the laser is mounted on
top of a 2" wide bubble level. As others have said, laser levels are
just a tool that come in handy in certain situations. Regular levels
and water levels are often easier to use and don't require batteries.
Same with laser distance measuring devices. I love mine, but I sure
wouldn't throw my tape measure or 6' rule away. ...Pat

Why not just use a gun with a laser sight. You point it
at the distant object to find the proper height and pull
the trigger. It saves having to walk all the way to the object to
mark it. I'm jus' sayin' ........

Sure is a labor saver. I like the idea.

Well, what you are saying takes no account of the physics and
trajectory of a bullet fired from a gun. It's is nowhere near a
straight line.

Gravity also "bends" light, so the laser wouldn't be totally

"As others have said, laser levels are just a tool that come in

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.

You are a moron if you consider the effects of gravity on a bullet and a
laser beam as being anywhere near similar to each other. Then there is the
effect of the bullet spin on it's trajectory.

If you had something like a swimming pool that you could calibrate it
with it might work but there is nothing magic about a laser level.
The pool builders all use a water level around here when they are
setting tiles or forming up the shell because the top of that water
will always be level and quickly point out the deficiencies of a laser
level.
Lasers are great for getting something flat (T bar ceiling, raised
floors, etc) but they are only as "level" as the calibration.


I demonstrated using a water level to someone and they were absolutely
sure that it couldn't be accurate especially since it didn't have a LASER.

But easy enough to check. Set the laser on each side and see if it
points to the same spot on the wall in each case. Then figure out
how to align it.

Actually, Einstein's theory of gravity bending the path of
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".....

Surfaces can release heat and will bend beams by refraction. I have not
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

There is no guarantee that the cheap laser levels sold at places like
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.

And of course you have built things stretching from the North Pole to

Actually you might find the indicated points in a water level at even

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.
