Situp N Grind converts all the useable
power from an angle grinder into speed
A 9 in. (230mm)
angle grinder produces enormous energy,
torque and motor speed from a
domestic outlet.
... but it has been difficult to
transfer that energy to the floor when
handgrinding while kneeling.
So maybe half the
power is wasted.
That means it
could take twice as long and cost you
twice the labour while kneeling to grind.
Actually it will
not take twice as long on soft concrete
if you
move it around in circles very quickly,
...however, on
hard concrete you can waste a lot of
time because it is too physically
exhausting to press hard and move it
quickly in circles at the same time for
very long.
When kneeling, if you do not
press hard on the grinding
disc on harder concrete the grinder will
not work close to its capacity and you lose money.
Up
to 6 weights
The Situp N Grind
tool has up to six extra
weights totalling 22 lbs (10kg) to
obtain the maximum performance
from the angle grinder motor regardless
of the concrete strength.
The proper way to
use it is to keep adding weights until
the depth of cut is too deep to float it
easily in circles. Then remove one
weight so you will be working at maximum
efficiency.
Motor loading
This will put a
noticeable load on the grinder if it is
cutting into the floor, but it will not
harm the motor, they are very robust.
Just a word of
warning here.
If you
really slow down a grinder for a minute
or two and suddenly
stop it, you may burn it out.

Ergonomics are important for
productivity
-
the stool is essential
The stool that
comes with a Situp N Grind is an essential
component to provide speed of movement
and excellent control of the grinder.
It allows the
grinder handles to fit between your
knees where you have the maximum
leverage and control with very low
physical effort.
That means you
can work hard for long periods and
you still have enough energy to work
hard some more.
The stool has a
height adjustment which is sufficient to
cater for tall and short persons because
it brings the hands to the handles.
With a hand on
each handle the grinder is switched on
by squeezing the trigger-switch and then
it is floated around in circles.
The stool can be
moved instantly in any direction with
the legs so the grinder can be floated
anywhere with almost no effort. The
weights keep the diamond cupwheel biting
in and the operator moves it as slowly
or as quickly as the job demands.
That is 100%
grinding efficiency that you can only
get from a Situp N Grind.
