The glass is usually 1/4 inch tempered
or safety glass, required by some insurance companies. In my own shop, I don't
feel the need for safety glass, because if broken, the glass would only fall
into the cabinet, and with protected gloves and sleeves, the chances for injury
are greatly reduced.
I've gone this direction, because replacing
tempered and safety glass can get quite expensive, especially if you change
glass once a week while doing heavy blasting. The frosting of the viewing
glass is the result of abrasive bouncing back from the glass you are blasting,
and hitting the window.
The window will get frosted more quickly
when blasting at higher pressures.
Some cabinet suppliers have plastic material
you can place on the inside of the glass to keep the glass itself from getting
frosted. If the plastic cover is not completely taped on all edges, abrasive
will collect between it and the glass, greatly reducing visibility. A static
charge will also build up on the plastic cover, causing dust to cling.
Each time the dust is wiped
off the plastic, it will leave scratches, causing it to be changed more often.
I find it more cost effective to replace the viewing window with single strength
window glass, rather than using plastic.
Because you will be changing
the viewing glass quite often, you should consider how easy or difficult the
change out operation will be.
Front of the Sandblasting Cabinet
 Some times, it is very
important to get as close to the glass you are blasting as possible. I find
this is important when I am doing delicate blasting on a face; the glass may
be no more than 12 inches from my face.
For me, this means a cabinet with a straight
front, specially designed for glass carving. Unless you build your own, these
cabinets can cost more, but can be well worth the price differential, since
cabinets with a 45 degree front design may not let you get close enough for
delicate work.
Hand Holes of the Sandblasting Cabinet
 Being able to have free movement on the hands and
arms is very critical when artistic blasting. Most cabinets come with rubber
sleeves and gloves attached to keep from accidentally blasting yourself.
These sleeves and gloves will restrict
your movement in the cabinet. An ideal cabinet will allow you to blast
anywhere in the cabinet with ease. Seventy percent of my blasting
is done without sleeves and gloves. I only use gloves when I am blasting with
pressure over 50 PSI to protect my hands from abrasive bouncing off the
glass.
Accidentally blasting yourself usually
happens once. It's like using a cigarette lighter; only once you burn yourself,
you respect the damage it can do.
I have some cabinets with just plastic
strips covering the hand slot across the front of them. This type of cabinet
allows total movement of hands and arms when doing airbrush technique blasting.
This type of hand slot is messier, because
it will let some abrasive out on the floor. This is the trade off I live with
so I can have total free movement of hands and arms. I find it very difficult
to artistic blast using attached rubber gloves.
Jim Yount uses gel-filled mouse pads to
soften the hard edges on the hand holes in his cabinets. He finds that in
long days of blasting, he tends to lean on the holes, and this can get really
painful after a day or two.
Cabinet Bottom of the Sandblasting Cabinet
 The bottom design of
a cabinet must be considered when choosing a cabinet. Can you sit down with
your legs underneath the cabinet, or will you have to stand all the time you
are blasting?
Blasting on a project for 6 hours gets
very tiring on the legs and feet, especially when you get "more mature",
like me! A flat bottomed cabinet that I can set on a table works best for
me. The disadvantage of the flat bottom cabinet is removing the abrasive.
I use a dust pan to scoop
it up and shift it through a strainer to remove foreign particles. Another
disadvantage of the flat bottom, the blasting air causes the abrasive on the
bottom to get blown up while blasting, producing more dust.
The V bottom cabinets are the most common
on the market. In these cabinets, the abrasive will fall to the bottom, where
it can be removed through a trap door. Because the abrasive is away from the
blasting area, less dust will be produced in the cabinet.

The disadvantage of V bottom cabinets
is the inability to sit down and put your legs underneath the cabinet while
blasting.
 There is a cabinet
on the market that incorporates both flat and V bottom. The front part is
flat, and the back part is V shaped. The cabinet allows your knees to go under
the cabinet while sitting and the abrasive falls down away from the blasting
area.
Jim Yount also uses this design
in his shop built second generation cabinet. You can see photos of his unit
on Note that he's going back to the straight V for his third generation unit.
Jim has also incorporated a vibrating screen in his new unit, so that the
abrasive has been pre-filtered inside the cabinet, before it is removed in
a sealed container.
If he ever gets the time, he  claims he'll write
an article on this new system. We'll see.
Cabinet Height of the Sandblasting Cabinet
The height of the cabinet is another item
you have to look at when choosing a cabinet. You
want a cabinet so that your forearms will fit straight through the sleeve
holes.
If you are blessed with being short, you
can always adjust the height by standing on a box. For tall people, it's a
different story; you have to extend the cabinet's legs, or build a box to
raise the cabinet to the correct height.
If people of different heights are using
the same cabinet, the height should be adjusted for the tallest person. It
is easier to change the box you stand on than change the box the cabinet stands
on.
Lighting of the Sandblasting Cabinet
 Proper lighting is
a must in any blasting cabinet, and I have used all types. If you use a florescent
light, you need to make sure it is sealed to keep the abrasive out of the
connections.
It's very hard to change the bulb when
the connections are full of abrasive. If a single incandescent bulb is used,
it must be placed to give light where you need it. Some cabinets will have
two lights to reduce shadow on what you are blasting.
My cabinet has an angle iron
across the inside top so I can use a clip on light. I can clip the light anywhere
from the left to the right side of the cabinet.
The light can be tilted in
any direction to focus on the light anywhere in the cabinet I want. When you
are doing artistic blasting, the angle of the light is very important.
I use a small spot light bulb, 75 to 100w.
The back side of the bulb is covered to keep the light from shining in my
eyes. Warning: abrasive will collect on the bulb and get very hot. You do
not want to knock the abrasive onto your hands or arms because it will produce
a serious burn.

Jim uses two swiveling spots that are
dimmable inside the cabinet, and a florescent fixture outside the cabinet
(shining in through an overhead window) to achieve much the same effect as
Bob's cabinet.
In addition, Jim also uses an LED edge
light fixture, attached to the glass during blasting, since most of his work
is small multistage carved pieces.
Slide and Pass Through of the Sandblasting Cabinet
 When you are shopping for a cabinet you need to size
it adequately for the work you expect to do.
Many people start with blasting glasses,
coffee cups, trophies and small items, so they start based on this workflow.
As their business or hobby grows, they start getting requests for larger flat
glass items that won't fit into their cabinet.
Now it's time to consider a slide or pass
through cabinet. I have seen three types of these cabinets: one has a slot
in one end of the cabinet so you can put one end of the glass in. After you
have blasted one half of the glass, you remove it and insert the other end
and blast it.
A second type has slots
in both ends of the cabinet. As you blast you keep sliding the glass thought
he cabinet. The height of glass you can blast in these two types of cabinets
will be limited to the size of slot in the cabinet. The third type has a slot
in both end and top.
The only limitation you have is twice
the end slot height. When you are blasting long pieces of glass, you will
need some type of support to hold the glass sticking out the end of the cabinet.
Some cabinets come with these supports and others don't.
When you are shopping for slide through
cabinets you need one that will accept 1/2 inch minimum thick glass. The material
used to seal the slot against the glass must be a type that won't allow the
abrasive scratch the glass. The slot must seal itself up so no dust escapes
out when no glass is in it.
Custom Blasting Cabinets
Open Back Sandblastin Cabinet
"What If" the plate glass you are sandcarving
was the back of the sandblasting cabinet? You wouldn't have to remove the
glass each time you wanted to see how your carving is proceeding.
If the glass was the back of the cabinet,
I could simply go around the back and see the blasted effect.
This was the thought running through my
head as I removed a large, deep carved piece of plate glass from the cabinet
for the fifth time. T
he glass only weighed 30 pounds when I
started, but by the time I finished, it must have increased to 70 pounds.
One would think the glass would get lighter because of all the glass I had
removed, not true.
Carving glass deep has always been a challenge
to me, because I am not sure how it will come out. When I am working with
a 30 inch by 48 inch piece, removing it each time I want to look at the back
side is not practical.
One way to get around removing the glass
so many times is to make the glass I am blasting the back of the cabinet.
Now it's just a simple matter of walking around to the back of the cabinet
and look at the glass.
With the light in the cabinet shining
through the carving I can see what it is going to look like hanging in a window.
 The big problem is how to seal around the glass
to keep the dust from escaping. This would be a large problem if I always blasted
glass larger than my cabinet.
It the glass stuck out on both ends and
the top of my slide through cabinet, it would be sealed except for the bottom.
In my flat bottom cabinet I could place some foam on the bottom for the glass
to set on.
With glass smaller than the cabinet, I
have to add spacers to make up the space difference.
The spacers are made from 1/4 inch tempered
Masonite with an aluminum H channel that fits over the edge of the glass.
To take up the space for the top of the glass, one large spacer will work.
For the ends of the glass different sizes will have to be used depending on
the size of glass I am blasting.
Blasting small flat glass and non-flat
glass in the backless cabinet, I installed a door to cover the back. With
the door closed on the back, it looks like a regular blasting cabinet.
I have just added a video camera at the
back of the cabinet connected to a monitor so I don't have to keep running
around the back. It's not that I'm lazy, but with the camera, I can zoom in
on the area I am blasting and watch as the glass is being removed. I had to
get used to watching the monitor instead of watching the glass. With some
practice, I  should get this down.
The open back cabinet and
video camera has increased the quality of my sandcarving.
These are some ways I have
changed my blasting cabinet to increase the quality of my sandcarving. You
may want to consider the open back cabinet and video camera and how it will
improve your sandcarving.
Dust Removal Ports of the Sandblasting Cabinet
The cabinet must have two ports for dust
remove - inlet and outlet. There must be air flowing through the cabinet;
the inlet port must be adjustable to regulate the amount of air going into
the cabinet.
Tom Eddleman and Jim Yount both duct the
air flow to opposite sides of the window, so that clean air enters the cabinet
on one side, and is pulled across the window during blasting. This way, the
viewing area is constantly cleaned.
The Sandblasting Cabinet: Conclusion of this Section
 In conclusion, my ideal
cabinet would be 24 inches wide, 30 inches tall, and 18 inches deep with a
20 inch by 12 inch vertical viewing glass. The arm slots would be large enough
for me to blast anywhere in the cabinet with ease. It would have a V bottom
with trap door to remove the abrasive.
The cabinet would be designed
so I can put my knees under it when I am blasting sitting down. The height
would be adjustable to allow people of different heights to blast in a comfortable
position. The slide through slots on the ends and top could be adjusted to
the glass could be moved closer to me when I am doing delicate blasting.
It should have an adjustable shelf to
set small items on while blasting. It would use a movable spotlight that could
point at any place in the cabinet. A door in the back would be nice, so I
wouldn't have to remove the glass to see the effect I am obtaining when blasting
deep. If the glass I am blasting was the back of the cabinet, that would be
even better. I could place a video camera in the back, and see the effect
as I am blasting it.
It may be impossible to get all these features
in one cabinet, but you should get as many as you can afford.

Blasting is the use of air
pressure and a variety of materials (called blast media) to clean and prepare
metal surfaces for repairing, painting or welding. Remove paint, rust and
oxidation in nothing flat! Blasting can also be used to change the condition
of the metal's surface. You can also remove casting marks and even etch glass.
If you're a professional technician or
if you have a car restoration project in your future, buying a sandblasting
cabinet may well be the best investment you'll ever make!
 Note on the Sandblasting
Cabinets:
All our Blast Cabinets and Blast Tanks
require the use of compressed air from a suitable external source, such as
your own shop compressor.
Our blast cabinets work best with a compressor
capable of producing 8-12 CFM and 60-100 PSI. The size of your compressor's tank will determine
blasting "duration" time.
Using a blast cabinet with a lower rated
compressor results in diminished blasting capabilities. Our tank blasters
typically perform best at 80-100 PSI. Their pressurized tanks act as a reserve tank in
addition to your compressor's tank.
Blast media under high pressure
can be very harmful and result in serious injury if used carelessly. When
using Tank Blasters, always wear protective eyewear, appropriate facemask,
and gloves to avoid injury. Only use approved blast media in your new sand
blaster or sandblast cabinet.

 Siphon vs. pressure
pot is possibly one of the most misunderstood facts in the blasting industry
today. Company product lines
often define the definition of this question. Media Blast manufactures all
types of abrasive delivery cabinets, wet, dry, siphon, gravity feed and direct
pressure. Portable pots and cabinets should be considered separately and the
information that follows is critical for proper selection of stationary blasting
cabinets only. In addition, abrasive type must be considered.
 Compressed
air is responsible for the actual part-cleaning rate not abrasive delivery
type. Compressed air is needed to deliver the abrasive to the part and the
volume of compressed air will establish how much abrasive, in pounds per minute,
and the frictional heat generated, in degrees Fahrenheit.
More compressed air volume in cubic feet
per minute gets you more pounds per minute of abrasive against the part. This
increases the frictional heat of the abrasive and produces the almost geometric
faster cleaning rate when the air volume is doubled.
FACT:
 Keeping the compressed
air usage and the abrasive velocity measured in miles per hour against the
part the same will result in abrasive delivery, pounds per minute, within
10% on the two types of blasting machine delivery systems.
Most abrasive grains can be destroyed with normal
air compressor line pressure. Even though a direct pressure machine can actually
create a faster abrasive velocity, the siphon type can also produce abrasive
velocities that destroy abrasive recycleability rates.
Except for steel shot and steel grit,
great for direct pressure machines, the siphon type is usually capable of
abrasive velocities exceeding the impact velocity of the grain.
Direct pressure machines require
pot re-filling that cuts into valuable production time. Not all part processing
lends itself to perfect pot reloading schedules.
Large part surface areas require
long blasting cycles. Long extended blasting cycles require pressure pot reload,
reducing production with production down-time.
Time and time again the welding
machine comparison has always had the ability to explain and clarify this
problem.
Compare the wire feed continuous weld
machine to the siphon continuous blast machine then compare the stick or rod
welding machine to the direct pressure machine.
Each has its pluses but with the rod welder
you need to stop about every 6 inches of weld and install a new welding rod.
With the direct pressure machine requiring pot refill the comparison is complete.
With the wire feed machine you start your welding and don't need to stop until
the wire spool is empty.
The siphon machine is very similar in that you
start blasting and don't need to stop until the abrasive is worn out from
maximum recycling. Many options
are available to help keep the pressure pot full but remember if direct pressure
machines were generally faster, every cost engineer would favor the purchase
of automated direct pressure machine types and it's just  not so!
You always have exceptions to every rule
and Media Blast offers the dual pressure pot assembly to permit continuous
pot blast but continuous blasting and continuous abrasive feed without media
delivery interruption are two separate items that require further explanation.
Call for details and Media Blast will
be happy to explain the difference and supply the equipment that is best for
your part processing, your production schedule and your compressed air usage
when considering siphon and pressure pot machine types.
Sandblasting Cabinet Equipment
The Only Cabinet you will ever need
 One of these cabinets
would be ideal for somebody thinking about starting their own buisness, be
it Sandblasting, Spraying, washing/rinsing, low-baking or a combination af
all these things put together.
These cabinets are more
versitile than any other cabinet on the market as they are designed for a
wide range of uses. Unlike existing cabinets these can be used for Shotblasting
anything upto the size and weight of a motorbike frame or engine down to something
as delicate as Glass Etching, they can also be used to wash, rinse or degrease
items in as well as spraying them, The cabinets can also be used to low-bake
items such as "Wheels" or any other freshly painted items to help
speed up the curing/drying process.
Unlike any other machine designed for these kind of
jobs these cabinets come as standard with a turntable, allowing the user to
rotate whatever is inside through 360 degrees, this saves the user having
to walk around the item tripping over pipes and cables that are in the way.
These cabinets are designed for a wide range of uses
and would save much time, effort and most importantly money in any workshop,
bodyshop or refurbishing plant.
Cabinets such as these are most commonly used
in the Aviation and Iuto Industry where engine parts, alloy wheels and other similar
things can be easily stripped, preparing those inaccessible areas for spraying/treating,
leaving a perfect finish which could never be achived by hand, and in a fraction
of the time !

The Sandblasting Cabinet 
: Sandblasting or bead blasting
This is a generic term for the process of smoothing,
shaping and cleaning a hard surface by forcing solid particles across that
surface at high speeds; the effect is similar to that of using sandpaper,
but provides a more even finish with no problems at corners or crannies.
Sandblasting can occur naturally, usually as a result
of the particle blown by the wind causing eolian erosion, or artificially,
using compressed air. An artificial sandblasting process was patented by Benjamin
Chew Tilghman on October 18, 1870.
Historically, the material used for artificial sandblasting
was sand t
hat had been sieved to a uniform size. The silica
dust produced in the sandblasting process caused silicosis after sustained
inhalation of dust.

Sandblasting may now only be performed in a controlled
environment using ventilation, protective clothing and breathing air supply
(as it is shown in the top image).
Other materials for sandblasting have
been developed to be used instead of sand; for example, steel grit, steel
shots, copper slag, glass beads (bead blasting), metal pellets, dry ice, garnet,
powdered abrasives of various grades, powdered slag, and even ground coconut
shells or corncobs have been used for specific applications and produce distinct
surface finishes.

How to make a sandblaster?
If you have a compressor,
the theory is simple: you'll need a hopper to hold the sand (5 gallons or
more - set it up high) a hose to carry the sand to a plumbing tee with about
an 1/8-inch inlet/outlet. you hook your compressor up to blow air across the
tee and the sand gets drawn into the airstream. it works kinda like a liquid
fertilizer canister on a garden hose in that the air goes straight thru and
draws the sand into it.
i used to have a store-bought sears blaster and it
took all morning to grain-out a beam for the fireplace mantle. i'd still use
store-bought sand though. work on a big tarp and you could re-use it. and
watch that nozzle - the sand cuts!

Build A Homemade Sandblasting Unit
 This photo presentation concerns the building of a
homemade sandblast cabinet. The apparatus is constructed from an
old dishwasher housing, which is just about the right size for a good sandblasting
cabinet, and which also has a deep well bottom for holding the abrasive medium/sand.
You will probably have to plug the bottom, after all
the worx are stripped. You should make it permanent. The dishwasher housing
is mounted on a wood base so that the arms are at a comfortable height above
the ground.
The arm holes are cut in the side of the DW housing
with a sawzall, or metal cutting jigsaw, and then fitted/lined with 4 inch
pvc fittings. The rubber gloves for the inside of the sandblaster are hose
clamped to the pvc on the inside. You may be able to salvage gloves with sleeves,
and if not, start your search at a safety equipment supply.
They should be heavy and entirely rubber coated. The
air is supplied to a spray gun via an air compressor of decent size. The bigger
the better, actually. The spray gun has a subsidiary intake which is modified
with an extension (flex Pipe/Hose) inserted into the sand reservoir at the
bottom of the DW housing, through a hole in the work-surface screen .
As compressed air from the compressor is jetted out
of the gun, it draws the sand through the intake embedded in the sand pile
at the bottom of the housing, to be jetted out alongwith the compressed air.
It has good sandblasting force. Different sands will do different things,
too.
The sand, and some of the blasted detritus, will both
find their way back to the bottom of the the DW housing, so it is a good idea
to clean the sand, or change it occasionally. Also, a
small diameter screen across the intake will keep the nozzle of the gun from
clogging too often.
A shopvac hose is inserted
in another penetration made at the top of the DW housing, to be used during
sandblasting for dust removal. A light mounted in the housing is a necessity
also. It should be across from the viewport, pointing toward where the work
will be.
The viewport in this cabinet is a piece of plexiglass
caulked over a penetration in the DW housing at the edge of the housing just
above the arm holes. It is about 4x8Ó on this rig, but I would have liked
it bigger.
The unit is of course closed entirely during operation.
A drying filter in the compressed
air line will make life a whole lot easier, and can probably even be used,
in some instances, to vary air flow.
Below is a closeup drawing of how the sand is picked
up and ejected by pressurised air:
 Some information on how a Sand Blaster works
 Sandblasters are very
useful tools in industry and art. Sandblasters are used to remove rust and
and unwanted finishes from metals, wood and even plastics. Sandblasters can
be used to etch designs into glass and metal as well as reduce glare from
glossy surfaces. Sandblasters work much like a perfume atomizer.
The perfume atomizer works by forcing air across the
open top of a tube that is sticking into a container containing the perfume.
The air flowing across the top of the tube creates a low pressure area. The
higher atmospheric pressure presses down on the surface of the perfume and
pushes it up the tube. The perfume then mixes with the fast moving air and
tiny droplets form (this is called atomization) that are carried out out with
the fast moving air.
The effect of fluid velocity on fluid pressure was
discovered by an man named Bernouli and is known as the Bernouli principle.
This is the fundamental basis for aerodynamics (and incidentally is exactly
how automotive carbuerators and airbrushes work).
Here is a simple experiment to demonstrate the principle
of atomization.
a.) Put about 300 mL water
in a 400 mL beaker and add some food coloring.
b.) Cut a plastic straw
with a knife or scissors but leave a slight hinge connecting the two pieces.
Bend the one half at a 90° angle.
c.) Lower the vertical portion
into the water. Blow through the open end of the horizontal part of the straw.
d.) Aim the atomizer at
a piece of white paper a few centimeters away. Observe what happens.
e.) If you have difficulty
getting it to spray, cut the straw through thoroughly and try moving the horizontal
part slightly with respect to the vertical straw.
The sandblaster works very much like a perfume atomizer
except the air pressure is much higher, 80 to 90 PSI, and the perfume is replaced with an abrasive media
such as sand, ground up walnut hulls, glass or ceramic beads, even ground
corncobs.
A high pressure air supply replaces the bulb of
the perfume atomizer (or your mouth in the experiment) and causes a very high velocity flow
at the nozzle of the sandblaster gun.
This high velocity flow causes a very low pressure
to develop at the end of the sand supply tube (similar to the tube sticking
in the perfume bottle) and the abrasive is drawn up the tube and sprayed onto
the object being blasted.
In short a sandblaster is sort
of a cross between a perfume atomizer and sandpaper. If you are interested
in learning more about the Bernouli principle you might check out this web
page (this is where the experiment came from): http://www.fortbragg.k12.ca.us/AG/PhysSci/bernouli.html
I hope this is helpful.
 Etched and Sandblasted
Glass with the Sandblasting Cabinet
Use a
sandblaster powered by an air compressor and an abrasive like sand,
to frost, carve and cut into glass. Also Cut Designs in Glass Beads.
The Sandblaster! Two different styles.
The Siphon Sandblaster
Has a simple container or hopper that
holds the sand (abrasive material). All of the action happens in the hand
held gun. As compressed air is released out of the nozzle, a vacuum is created
a couple inches from the nozzle.
The sand tube is attached at this point,
and the vacuum sucks sand into the compressed air stream. Out comes a mixture
of air and sand. The grains of sand hit the glass and chip out a small piece
of the surface "sandblasting" the glass.
Advantages of this Sandblasting Cabinet
 Costs
less than a pressure blaster. There is a lot of control. There is a button
on the hand held gun. You can instantaneous turn on and off the spray. The
entire device is simple and is easier to maintain than the pressure system
listed below.

The system is not as powerful as the pressure
system below. Surface blasting is no problem, but deep
carving into the glass takes longer than with a pressure system.
The Pressure Sandblaster
Has a sand container that is closed and
pressurized. The mixing of the air and sand happens a few inches below the
sand hopper. The sand/air mixture travels through a hose until it leaves at
the nozzle.
Advantages of this Sandblasting Cabinet
This sandblaster is more powerful and
can carve deeper and faster than the Siphon System described above.
Disadvantage of this Sandblasting Cabinet
Costs more than a siphon blaster. There is no simple
on/off. Once you get the system adjusted and going, it stays on. The system
is more finicky, subject to clogging and continuous adjusting.
How to sandblast - Best of Blasting : Resources for all abrasive blasting
professionals
How to sandblast?
This is the most common question when a surface has to be cleaned.
Best of blasting provides for all the questions one has concerning
different methods of sandblasting and how to sandblast.
Experts are here on the forum to give
advice on how to sandblast through the users' forum. Other important
info on how to sandblast
are available all over the site and the practical know how sections
will help you prepare for the best results on how to sandblast.
Sandblasting can be used as an accent
to your stained glass or fused glass, or it can be the major aspect of your
glasswork. With an understanding of the basics and a little creativity, this
technical toolset can help create reproducible effects that are otherwise
impossible to create.
Sandblasting Materials and Methods
Most materials be sandblasted
except for diamond which is harder than all sandblasting media. Stone is regularly
sandblasted as a way to create gravestones and memorials.
Metal is sandblasted to remove rust and
sharp edges or as a way to enhance adhesion of coatings and adhesives. Wood
and brick is sandblasted to remove years of paint, oil and dirt and to produce
a clean surface for staining and painting.
Certain types of plastic can be sandblasted
for decorative effects, but the work has to be done very carefully, as the
plastic can be much softer than the abrasive and will wear away quickly.
By mixing air under pressure with a hard,
particulate abrasive or media, material can be slowly abraded or worn away
by directing the abrasive stream onto the surface of the material.
The longer the abrasive stream is held
in one spot, the more material will be removed. Moving the nozzle closer to
the surface decreases the area being blasted, and increases the rate of material
removal.
By moving further away, the area increases
and  the rate of removal decreases. If the nozzle is held
very close to the material, a hole can be abraded through the surface very
quickly.
Glasswork with the Sandblasting Cabinet
In glasswork, sandblasting
can used to etch a pattern into the glass surface, creating a frosted effect.
A three-dimensional design can be carved into the glass volume by using a
“stage-carving” technique where some parts of an image or pattern are carved
deep into the glass while others are carved shallow or only surface etched.
Sandblasting can also be used to selectively
etch the surface of the glass to remove iridescent coating, enamel or micas.
Also, sandblasting can also be used to remove kiln wash or fiber paper that
has stuck to the glass surface during fusing.
 Sandblasting can be used to decorate ordinary objects,
such as bowls, bottles, glasses, vases or candleholders. Artwork and lettering
can be etched into glass windows for decoration or identification. Sandblasting
can also used to customize awards by etching names and other information into
glass or metal objects. Mirror can be etched from the back, removing the mirror
coating to create interesting effects.
Conventional "cut resist" methods"
The first step in sandblasting
is obtaining a pattern or design. A two-dimensional design can be as simple
as a heart shape, stars or some lettering. A rubber or vinyl sheet material
is applied to the item that is to be blasted. The sheet material, which is
referred to as "sandblast resist", is applied to the item to “resist”
the effect of the abrasive stream.
The pattern or design is then transferred
to the resist material with ink, pencil or carbon paper or by “pouncing”.
By cutting through and removing selected portions of the pattern, the unprotected
surface of the item will be exposed to the abrasive stream where material
will be etched or carved away. This is called a positive etch, where only
selected areas representing the pattern are etched. An alternate etch, known
as a negative etch, can be achieved by leaving the resist on the pattern and
removing the background areas.
Photoresist methods with the Sandblasting Cabinet
Recently, ultra violet sensitive film technology
has been applied to glass carving, with the result that very precise resists can be
created using a photographic process. Lines as fine as 0.003 inches (0.20
point), lettering as small as 3 point type, and halftone photographs can be
produced on glass and other materials. The process lends itself well to multistage
carving, in depths to 1/4 inch and greater, depending on the size of the element
being carved. The original line art can be hand drawn, but there are significant
advantages to using a computer in the process: line weights can be carefully
controlled, to ensure a successful resist.
Basically, the process involves:
- generating
the line art,
- creating
a positive film image of the art,
- exposing
the resist to ultraviolet light,
- washing
the resist to create open areas through which the abrasive will pass,
- applying
the resist to the glass
- and
blasting the glass.
For multistage work, the individual design
elements are "cut" by the abrasive on the first blast, then removed
in sequence as needed.
 The advantages of photoresist are the incredible detail
possible with this method, and the elimination of the tedious process of hand
cutting the resist.
Disadvantages include the addition of
computer and photographic technologies to the carving process, and the high
cost (five cents to nine cents a square inch) of the photoresist. As the size
of the work grows beyond several feet in each direction, the degree of difficulty
and cost of the materials grows significantly.
Complex images with the Sandblasting Cabinet
Complicated images can be etched onto
the surface of glass, but care must be taken to ensure that adjacent pattern
sections are separated by unetched areas.
Another method would be to allow the adjacent
pattern areas to touch and to shade the different areas by having a lighter
etch in some areas and a heavier etch in other areas.
This technique is difficult to master and requires
a good artistic sense of black and white shading.
By selectively removing pieces of a pattern
and blasting different areas to different depths, a three-dimensional shape
can be carved into the glass. This is commonly referred to as glass carving
or sandcarving.
Techniques have to be developed by the
glass artist to deal with adjacent and overlapping areas in a pattern. These
are typically done by numbering the pattern sections by depth and selecting
the deepest pattern sections to carve first.
The glass artist must stay away from areas
that have already been carved to preserve the detail in that section. By carving
the glass in stages, intricate sculptures can be created in a two-dimensional
piece of glass.
By creating a two-dimensional
etch on the backside of a mirror, the pattern can be developed where certain
areas of the mirror coating have been removed, and other areas remain. The
etched surface can be left frosted, or can be back painted to add some color.
Back painting has an interesting effect in that it appears that the color
is embedded in the glass.

Blasting with the Sandblasting Cabinet
Once the resist has been applied to the
glass, the next step is to pressurize the pressure pot or connect the siphon
blaster to the compressor and blast the glass, normally from a distance of
about 2 to 6 inches away from the surface.
Using a painting motion, and overlapping
areas, a uniform etch can be obtained. When blasting to different depths,
selected areas of resist are removed and as opposed to etching, where you
try to get a uniform frost over the entire piece, the sandblasting is concentrated
on small areas of the item.
The edges of the resist are traced to
obtain a sharp edge and the open areas can be carved deep. Special techniques
are used to deal with overlapping sections such as twisted vines or leaves.
Sections of resist covering successively
shallower areas are removed and the blasting continues until all sections
have been peeled and carved.
 After etching or carving, the item is rinsed off under
water, being careful not to drag any grit across the surface of the glass.
A single particle of silicon carbide can ruin a glass surface
or the back of a mirror because it is much harder than glass and will make
a very deep (and very obvious) scratch in the surface, so it is
very important to ensure that all media had been washed off.
You also do not want to transport any
grit to your workbench where it could scratch a piece of glass in the future.
After washing and drying, the entire piece
should be inspected to see if any areas were missed. This is the time to
catch any missed areas, because once removed, the cut resist cannot be reapplied.
Also, it is very difficult to apply and properly align a cut using new resist
on a piece of glass that has been sandblasted.
The resist can now be removed from the
glass, and any paint (if desired) applied.

Suppliers of the Sandblasting Cabinet
 There are many suppliers listed on this page.
Shortcuts and cost savings for the Sandblasting Cabinet
Use heavy duty air hose instead of sandblast
hose – 10% of the cost (and a fraction of the life).
Use Silicon Carbide media,
more expensive initially, but lasts much longer.
Use Quartz Halogen floodlight
in cabinet
Cover vacuum port with a
plate on standoffs or a bent U-channel of sheet metal to reduce abrasive loss
into vacuum. Or use an in-line reclaimer
Process of Using the Sandblasting Cabinet
  Sandblasting is a generic term for the process of
smoothing, shaping and cleaning a hard surface by forcing solid particles
across the surface at high speeds.
Historically the material used for sandblasting was sand that had been sieved
to a uniform size, that's why it is commonly known "sandblasting".
Nowadays many other better materials have been developed to sandblast, such
glass beads or metal pellets.
- Sandblasting Equipment & Tools -
There are many different tools you will find in a sandblasting workshop
from the air compressor to the abrasives. Here you have the main
list;
* Air compressor
* Blasting cabinet or booth
* Blast gun or nozzle
* Abrasives
* Safety glasses
* Safety respirators & filters
* Apron
* Knife
* Permanent marker
* Straight edge
* Glass cutter (if blasting on glass)
* Running pliers
* Combination pliers
* Carborundum stone
* Sandpaper
* Carbon paper
* Squeegee
There are two different systems for sandblasting; the siphon system and the
pressure-pot system. The latter is faster, easier to control and adjust.
The siphon system uses the same principle as conventional paint-spraying equipment.
Sand is stored in a pot, sucked up through a connecting hose, mixed with air
in the nozzle and projected onto the object being blasted.
The siphon system requires a large volume of air
to draw the abrasives. It needs pressures between 80 to 100 psi (pound per
square inch) which requires a 10 HP (Horse Power) compressor.
Alternatively, in the pressure-pot system,
air not only flows through the sand-delivery hose; it's actually introduced
into the sand pot itself. This helps to push the sand trough the hose which
makes it more efficient and up to 4 times faster than the siphoning system.
Air flow and abrasives can be easily adjusted
as required. The air pressure needed is between 20 to 40 psi and requires
a 2 to 5 HP compressor.
- Abrasives for the Sandblasting Cabinet –
There are a few different types of abrasives available
in many different grits. Depending on what substrate you are going to use
and the effect you are trying to achieve.
Sand still used by some DIY'er but nowadays is the worst of the options. Aluminium
Oxide and Silicon Carbide are the best choices.
* Silicone Carbide
 does not dull as it brakes down and can be used many
times producing little static electricity it is more expensive.
* Aluminium Oxide
also can be used many times, it generates
more static which makes it worse to work with but it is cheaper than Silicon
Carbides.
- Sandblasting Area of the Sandblasting Cabinet –
Basically, you have three options: a sandblaster cabinet, your backyard and
a sandblasting booth, however this latter one probably isn't an option unless
you are thinking of setting up a sandblasting business.
* A sandblaster cabinet
is basically a large box with a front
window and two holes with built-in gloves. You place your object in the cabinet,
insert your hands into the gloves, look through the window at your project,
and blast away.
Cabinet sandblasters will
keep the bulk of your sandblast mess inside the cabinet. The downside is that
the size of the object you can blast is obviously limited by the size of your
cabinet.
* By sandblasting outdoors,
you're not limited with space and this
is practical for bigger projects. You can also use your sandblasting equipment
to work different projects like removing rust from garden furniture.
Blasting in the open air is messy and hazardous.

Because of these hazards you should limit
yourself to doing it indoors whenever possible. However you're definitely
restricted by the Environmental Protection Agency (EPA) regulations.
- REMEMBER about the Sandblasting Cabinet –
  Research outdoor sandblasting restrictions in your
area before starting up a backyard job.
* A sandblasting booth is just a room set up only for sandblasting.
A good compromise between the other options,
a booth allows you to sandblast both large and small objects while keeping
your mess contained.
- Do It Yourself Sandblasting -
Setting a sandblasting workshop isn't cheap. If you are considering this option,
think about the cost before making any decisions.
Does the amount of sandblasting work justify
the equipment expense?
If you are just a DoItYourSelfer the answer is probably not. In this case
you can do all the preparation & design and send out the blast work to
a professional.
You'll probably find an industrial sandblasting workshop not far from you.
Try a Google search for - sandblasting workshop - at http://local.google.com
. (or any other local search engine).
Without the right equipment, it could take the sandblasting DIY'er hours to
do a job that can be done in only a few minutes by a properly equipped professional
sandblaster.
