Hello folks,
I am in the market for a compressor and spray gun for
my home studio use. I generally spray platters at a
clay studio that I belong to. They use a standard
Bailey Spray Gun and a $239 compressor from Home
Depot. Went to Sears and Home Depot (saw a small
tabletop compressor for $99) to get an idea of prices
but in the end, I'd really appreciate any suggestions
this group might offer.
Thanks in advance,
jody lebrenz

Vince is right.
(In my previous post I referred to CFS (Cubic
Feet per Second); that's not wrong, exactly, but
CFM (Cubic Feet per Minute) is the measurement
used in the industry to rate capacity, and the
one you will find printed amongst the relevant
specifications.)
Sorry for any confusion!

Just a thought.... for someone who likes to make do on minimal until conditions
(sales) warrant a larger investment. ...my first "air compressor" was an old
refrigerator compressor. I rigged it to go through a home made oil separator and
dryer (cotton wadding) and it ran quite well for quite a while. True, it did not
look "fancy, but it did not have a "fancy" price tag, and it did the job. My first
air tank was an old water heater with safety valve. Just a thought.

Jody,
Do an archives search on Vince Pitelka as sender and compressors. He
has written several times with excellent information on compressor
selection.
Basically, he says get one with a steel cylinder.
Lots of sprayers out there, information in the archives also. I like
the Paasch 62, because it has no removable parts--quick to clean up. You
can find plastic bottles to fit it. The standard 3-oz. glass ones are too
small for me. Extend the dip tube with plastic tubing to reach the bottom
of the bottle.
Good glazing!

This has been discussed a number of times on Clayart, and you can find that
information in the archives. The small tabletop compressors are inadequate
for anything but airbrushing. You need at least 1 1/2 or 2 horsepower, and
a good size storage tank - at least ten gallons. Avoid the compressors
advertised as "oilless" or "maintenance free." They do not last long.
Those are the ones where the compressor unit is direct-coupled to the motor.
What you want is a unit with a cast-iron compressor barrel (around the
piston) or at least a cast iron sleeve within an aluminum barrel. With any
magnet you can check to see if the barrel is cast iron, and the sales
literature should tell if there is a iron sleeve.
The "oilless" or "maintenance free" direct-connected compressors run very
fast, and have solid aluminum compressor barrels in order to dissipate the
heat from the increased friction. As a result they wear out much more
quickly. And at that higher speed the manufacturer can also get much more
CFM output from a smaller compressor unit, but that is no advantage at all
when the trade-off is a shortened lifespan.
The better compressors all have a V-belt drive between motor and compressor,
with an oil-sump in the compressor crankcase. The compressor runs at a
slower speed, and if properly cared for the unit will last you the rest of
your life. Campbell Hausfeld's "Cast Iron Line" is an excellent low-cost
choice. You can find them at www.grizzlyindustrial.com and at many of the
big home improvement centers. I bought mine at Montgomery Ward almost 30
years ago, and its performance has not diminished a bit over the years.
Other good brands are SpeedAire, DeVilbiss, Quincy, Ingersol-Rand - they
will be a little more expensive, but almost all of these manufacturers now
have lower-priced cast-iron compressors in the $300 to $400 range to compete
with the crappy imports that most dealers are selling these days.
Good luck -

Jody-
The type of small compressor you are
referring to (I think) is the sort sold
for operating pneumatic nailers. They make
them small and portable so that construction
workers can carry them around the jobsite,
and up onto roofs.
Pneumatic nailers are 'intermittent use'
tools. They use air only when a nail is
fired, so they use less air than a
'continuous use' tool. So, the compressors
sold for powering them may not be appropriate
for running other tools.
The main number to know is 'CFS': Cubic
Feet per Second. The other number to know
is 'PSI': Pounds per Square Inch. These
numbers will be posted on the tool you
wish to use, and on the compressor. Most
compressors, including the one you describe,
have ample PSI for your purpose. Spray guns
generally don't require a lot of pressure.
They do use a lot of CFS, though, since they
are 'continuous use' devices. Compare the
CFS requirement of your spraygun with the
rating on the compressor, to be sure what
models will work.
Note also that those tiny-tank compressors
have to run almost continuously to provide
pressure, since they can't store much. This
may or may not be an annoyance to you, but
it's something else to consider.

I use a small Sears compressor that delivers about 25-30 psi. I use it with a
jelly jar sprayer. It works just fine and is much quieter than the large
compressor I use for other things.

Dear Jody:
We do alot of spraying in our studio . The one thing that I can
say is do not buy to small of a compressor for the job. A small tabletop
compressor is definately undersized. We first baught a 20 gtallon tank
compressor from sears and within 6 months burned it out. This wound up
happening at the worst time of course right in the hieght of the christmas
season. So we went to home depot and baught a 5.5 horsepower 40 gallon tank
compressor. Make sure you buy a compressor with a big enough tank so that the
motor does not run constantly.
Cindy Gatto on tue 29 may 01
Dear Jody:
Sorry I accidentally hit send without finishing the post.
As I was saying make sure you buy a compressor with a large enough tank so
that it does not run allday. They say that the motor should run no more than
half the time that you are spraying or you are overworking the compressor I
hope that this has helped if you have any more definitive questions please
feel free to contact me.

'Senco' makes, or sells under their name, an dandy wet-sump Compresser made
to run Air-Guns, Nailers and the like, and I would expect it would run a Cup
Gun or other paint or spray outfit just fine.
A friend of mine just bought one, and I liked it a lot.
It is quiet, well made and would likely last a long time and enjoy a healthy
resale value should one choose to sell it after some years...it is a nice
portable unit, and looks good as well.
This one is 'rated' at Two-Horsepower...I believe there is a One-and-a-Half
Horse model as well.
It cost about Three-Hundred Dollars and low change.
I would be very hesitant to buy anything in the way of Machinery or earnest
Tools, at 'Home Depot', unless I was already familiar with the Brand and the
model...
Go instead to a 'real' Tool Store, where Tradesmen and Professionals make
their purchases...as under the Yellow Pages section of Tools, Wholesale and
so on, call them, see what you can do...if you have a business or not, often
they will be worth looking into.
Forget 'Grainger' or however you spell it...look for someplace that is
smaller, but serious.
And they are usually able to answer your questions with more
experience...than the folks at 'Home-Depot'...and will have much 'better'
things to choose from.

Get something bigger than a diaphragm compressor.
I went for the cheapest and wish I hadn't.

The problem with this type is that they overheat if used for more than
about 20/30 minutes at a time. As they are oil-less you can guess what
will happen! Give them a shortish cool-down period every half hour and
they're OK, usually.
