Spraybooth
Hello Tom,
I have been using an old fiberglass shower for a spraybooth. Cut the top
1/3 off and added a sheet of plexi glass to the top and three 4 foot shop
lites on top of that and a waterproof two speed exhaust fan from
Grainger's . It also has hot and cold water and drain for cleanup. It
serves as my spraybooth and sink. Its mounted on a stand and I have a
small ice box under it. Hope this is of some help. You can reach me at:

I am looking for any information that is available to construct my own
spraybooth. Does any one have any thing to share? Thanks in advance! Brntdrt

Just a thought..I have seen several spraybooths made out of old appliances.
The "Shell" of an old stove, drier, refrig. can give you the "skeleton"
with which to make the box. I would think a structure 3' x 3' x 3' would
be minimal size. Be sure to Vent the spray booth, and make sure the
fan/blower moves sufficient CFM (cubic feet per minute) of air to pull the
dust away from you and your inside environment. Probably vent at the back
top area....and to the outside of the building you are in...and use some
sort of screen/filter to capture the dust...so it doesn't end up in the
environment, or your neighbor's yard or nose....Isolate the motor away from
the dust...belt driven.........or use a sealed unit....glaze is very
abrasive to electric motors. DO NO USE flammable sprays...paint and so
on...unless you are sure the blower won't cause ignition of the fumes that
can build up in a booth.
You might even be able to recycle some of the glaze...if you do a lot of
spraying in a single color or ...combined glazes...sometimes called
PHOENIX EYE (F. C. Ball called it that)...usually a light to dark green
color...but could be anything! NEVER REPEATABLE!
A really nice spraybooth can be made by a "tin-knocker" your local
sheetmetal shop/roofing company. Draw what you want and they can make it
up for you to order. It's more expensive, but would take less of your time
away from potting. I had a hood made up for my kiln....by a sheet-metal
worker....the guy did a beautiful job and didn't charge a fortune either.
The seams were really interesting. A lot of people know all this because
THEY took metalshop in school.....I did not...and have regretted it ever
since!
Put the booth at a comfortable height for you...use a "banding wheel" to
spin pieces as you glaze them. There are other considerations that will
depend on your situation......hope this helps...

I put one together for less than $200.00 cdn.
I found a second hand squirl ventilator, used for a house oil furnace,at a
flea market, $50.00 purchased a 72" high corner storage shelf at $75.00,
Two 4'X8'X1/8" glossy white wall panels for $30.00, two small spotlights
$12.00, two vent ducts and 5 feet of accordian vent pipe used for home
heating and some electrical wiring from a home builders supply, totatling
$20.00. I put up the shelving in a corner,next to a window. I installed
the top shelf right at the top, the bottom shelf up approx 3" from the
floor, the second bottom shelf was installed 4 to 6" higher. This is the
shelf that the ventilator will sit on and the space between the bottom and
second shelf makes a great storagae area for my compressor hose and spray
equipment. The 4th shelf, or the floor of the spray booth, was installed
high enough to allow the ventilator to fit between it and the shelf below. I
installed the ventilator on a soft sponge base and used more sponge as a
gasket between the exhast part of the vent and the wall of the booth. Once
the ventilator was in place and wired. I drilled a double rowof 1" holes
along one back side of the spray booth floor and built a filter box with the
open end that sits over the holes resting against the back wall, whereby the
air would be pulled down through the filter. Thind of this as a lean too,
leaning against a wall. The filter is the angled roof of the lean too. This
item is attached temporary as I want to be able to change the filter easily
and If need be remove it form time to time in order to do a larger piece. I
have yet need to remove the filter for other than replacement. My exhaust
pipe is the installed to the ventilator using furnace duct and scrap plywood
cut to fit nicely into the open window becide my booth. I duct tape all the
edges to ensure no leaks. I will eventually use chalking for this task. I
installed the lighting so that when I turned on the vent the lights would
come on automatic. It works. I even use the ventilator for an air exchanger
on warm days. This helps keep the dust down.
I know this sounds complicated but it works.

Hi Stacy,
We got a salvaged 3' industrial fan, cut a hole in the wall (maybe not an
option for you), mounted and motorized it. Framed a box around it and tacked
up some plastic sheeting. Its been in daily service for over two years but
the plastic tho tired still puts in a full day's work.
The big problem is that it sucks out all the heat in the winter. Sugar Creek
makes a little spray booth for I think it was $3-400.
Don't not use one! Have fun.

Woods Cross High School, Woods Cross, Utah has two De Vilbiss
Spraybooths we are selling. We need the money and the space for a
new kiln. Exhaust fan modle number is JF4686 and Motor number is a
General Electric FS615146. One has never been used and the other
has approxiametely 40 hours of use on it.

C. Guy -
Commercially-made spraybooths which are powerful enough to do any good are
very expensive. It is far better to make your own. You can either build a
permanent booth, or simply have several hinged arms with canvas or plastic
curtains which swing out from the wall to create an open-front booth. That
way the counter or table can be used for other purposes when the spray booth
is not in use. The size of the booth and the size of the opening are
dependent on the size of wares you need to spray. Keep in mind that the
height of the spray booth must include the maximum height of your wares with
some space to spare, plus the height of a banding wheel upon which to place
the wares while spraying. The larger the spraybooth, and the larger the
opening at the front, the more powerful the fan needed to effectively
exhaust the overspray and fumes (if any are present).
The heart of the spray booth is the exhaust fan. Do not use a squirrel-cage
blower, as the small vanes will get clogged with overspray over time, even
if you have a filter. Use a good quality propeller-style fan (like a
box-fan, only better), or use a snail-shell blower with large paddle-style
vanes. You can find them in the Grainger's catalog. Get one with at least
a 1/4 HP motor.
On the face of the exhaust outlet at the back of the spray-booth, mount a
filter, like an ordinary household furnace filter, so that it is easily
replaced. Furnace filters are cheap, and you will want to replace it
frequently to keep the exhaust suction as high as possible. At the back of
the spraybooth in front of the filter mount a vertical baffle - just a big
piece of plywood, spaced out three or four inches from the surface of the
filter, so that the overspray has to go around either edge of the baffle,
rather than landing directly on the filter. That will assure that the
overspray is dry by the time it hits the filter.
This has been discussed before, and you can probably find good information
in the archives.
Good luck -

While in a nearby home improvement superstore, I passed the inexpensive laundry
tubs on legs and wondered if it could be used as a spray booth by setting the sink
on its side on top of the legs???? Has anyone ever done this? They are
lightweight, cheap, easy to move around, etc.

I have made a Mark1 spraybooth over a Leach kickwheel.
The slop tray has vertical sides and the form is trapezoidal, so it is
relatively easy to cut material to fit inside.
I make the sides of plastic sheeting, but one side, towards which the spray
will be directed, will be of wood with sponge cover in Mark2.
One side has the opening for putting ware in and taking it out, on recycled
CD discs. The spray gun(s) operate from the right hand side through this
opening. The wheel turns in the normal way.
In Mark2 a redundant vacuum cleaner will be connected to the unblocked slop
tray drain tube to the adjacent open window, to take out the air-borne
particulates. The top is covered with Perspex.
The front is plastic in Mark1 but will be glass in Mark2, so that I do not
have to keep cleaning it.
Glaze can be caught for recycling by a small channel at the bottom of each
side and from wringing out the sponge stuck with Velcro to the vertical side
opposite the sprayer opening. That side, in Mark2, will also flap open so
that ware can be put in and out more easily.
This arrangement is flexible and can be easily parked elsewhere so that one
can use the Wheel normally.
Those sold commercially are usually large, need extra space and still do not
permit one to turn the article as one can on a kick wheel. But special
attention needs to be paid to make sure that one has given the same amount
of glaze spray to the sides and underneath of handles as on the outside and
inside surface of the pots. Just needs spraying the handles at 90 degrees
instead of head on.

Joanne, that's a good idea; but instead of paying $25-$30, go to some of your
local appliance stores. They often have worn out, traded in appliances in the
back lot. An old dryer would make a good spray booth and the cost is right.
People, myself included, when buying a new appliance, often make a deal with
the store to remove the old one. I have found interesting things in those
lots, including good sized metal racks from industrial coolers, free pallets,
etc. etc.

June

Thanks for sending the link! I did a search on the Internet and I did
find your blog where it was originally posted, I believe, or one of
the one you built; however, the pictures were gone and I was saving it
for later to see if I could decipher it. Too funny.
Thanks!

Great spray booth. I have cleaned blower blades before. I like the idea =3D
of no filter because the filter needs changing or washing frequently. =3D
The potters wheel as the turntable is brilliant for reasons of avoiding =3D
breathing glaze dust is an excellent solution.
Thanks Richard.=3D20
