The rotary
self leveling laser level is one
of many levels used by woodworkers to ensure
that work is consistent and accurate. Some prefer
to use the more traditional levels, which include
the kind with the bubbles. While okay for occasional
use, many professionals who use levelers on a
regular basis find laser levels to be helpful.
There are many types
of laser level, of which
the rotary self leveling laser level is one.
Additionally, another type of level is the optical
level. This level, while it does not use lasers,
is easy to use and quite accurate.
The rotary laser level
By definition, rotary laser levels offer a circular
level. This means that the level can perform
its function anywhere around it, covering 360
degrees. A laser beam is used to indicate where
various objects and cuts should be placed or
made. Most self leveling laser levels actually
use electronic sensors to communicate with motors.
This keeps the level constant, without the need
for continuous adjustment by the worker. Additionally,
there are many of these self levelers that are
equipped with a device that alerts the user if
the height of the instrument (the level) has
been altered (by a bump or accident). Because
a laser level uses a concentrated beam, it can
extend further than conventional levels, allowing
for ease of work on big projects.
The optical level
An
optical level uses slightly different technology
to help adjust the optical line of sight. This
is done by using a system of mirrors and pendulum,
in order to align with the earth’s gravitational
pull and help the user determine whether a surface
is completely level. The reading is determined
from an autocollimator, and is accurate within
one arc second. This can be very helpful when
doing work in the shop. As with laser levels,
an optical level can be self checking and adjusting.
This makes the need for readjustment rather minimal.
An
optical level can be useful, but a laser level
is one’s best bet when working on
very large projects. Its ability to reach sometimes
up to 300 feet away make it ideal. To use a level
that can be placed anywhere in the workshop and
still be used as a level, try a rotary self leveling
laser level.
