Re: Cheap CompressorsFrom: Anthony Lloyd-Rees firstname.lastname@example.org
Hello Dave, I know a few people that have a foot pump hooked into
their wax injector, it doesn’t need many pounds. Hint: the two
cylinder types seem to last longer as they are a bit more
sturdily built, a bike pump would even do it.

You can find refridgerator type compressors in art supplies
shops but the only advantage they offer is (almost) silent
running. They cost an arm and a leg ($600 up, you pay mostly
for furniture and a fancy paint job). They are really too small
a capacity for any real work outside airbrush painting.
If you have a handyman around just salvage a working compressor
from and old refridgerator and bleed off the refrigerant (may be
a fluorocarbon, don’t pollute the atmosphere). Be careful to
keep the compressor upright as the sump is filled with
lubricating oil which may spill out through the cut tubes.
Other hobby compressors, mostly diaphragm types, are likewise
limited in capacity and over priced as you have found.
The best buy for a compressor is still from a regular hardware
shop such as SEARS. Get a tradesman quality one of at least 3HP
and up, with a 13 Gal tank or larger. A $200+ budget should get
Outside your jewelry work the compressor will be very useful
for painting your fence and house and I really love air tools
like wrenches, drills, sanders, etc. which are light,
inexpensive and self cleaning. You never have to worry about a
motor burning out when its stalled or getting eletrocuted when
working in a wet environment (wet lawn or floor). Fix up your
fender bender and the savings will have paid for the compressor
Get the largest compressor your budget and space will allow.

Hi Dave, The air compressors we sell at Gesswein for example ARE
expensive because they are virtually noisless. When you pay a
lot for an air compressor (at least from us) you are paying for
peace and quiet. They are designed to be quiet for people who
are forced, for whatever reason, to keep the compressor close at
hand while they work.
I picked up a compressor at Home Depot for about $200 (this was
a couple years ago) and it was 6 HP! It’s noisy!! but it’s good

Try a salvage yard or small or a appliance repair store…I’ve
even seen them at flea markets
Aloha Dave, Why not use a portable air tank ($30-35).Just go fill
it at the service station. We have used on for years and they
hold 125 PSI, depending how many patterns you shoot in a day, it
lasts quite awhile. Remember to use teflon tape on the fittings
(to help insure a leak free system) and put on quick couplers (on
the wax pot and tank hose), to aid in quick attachment and
removal. We use it, because the compressor we have, is quite
loud (5 HP). I even saw a guy use the spare off his truck!!!
Dave: A commercial caster friend of mine who is very handy
answered this question for me back when I was looking for a wax
injector. The pressure needed for the wax injector is only a few
pounds — under 10 psi. He says you don’t really need as
compressor at all if you are not shooting a lot of waxes. You
can use an air tank, get it pressurized somewhere ( there are
still a few service stations with free air here,and I can fill
my tank to over 100 psi ) and connect it to the regulator on your
wax injector. Since the pressure is low and the volume of air is
small, your tank should last a while if there aren’t any leaks.
You could even fill it with a foot pump or some such. There is
even a company locally which sells a $10 kit to convert a freon
tank to an air tank — the kit includes the fittings, hose,
Making a compressor from a refrig compressor (some kinds work)
or an auto air conditioner compressor should work (I have a
vacuum pump made from a motor and an old auto a/c compressor),
but the problem is that you still need a tank and a switch and
various fittings in order to maintain 5 to 10 psi constant on the
inlet side of your wax injector regulator. I looked into this,
but the parts look like at least $50, and there is a good deal of
fabrication involved. When you have to have a compressor (you’re
going to get a pneumatic hammer handpiece eventually, right??),
$150 should get a used one at the pawn shop or some such place.

Dave, try Goodwill, used furniture stores, etc., for an old
fridge. If you can’t find that, try one of the paint stores or
big hardware chains for a paint compressor–I picked up a 150 psi
maximum compressor with adjustable setting for 20 to 150 psi for
about $140 couple of years ago (at Lowe’s, of all places!). Good
luck. Sharon Holt

Dave, if you’re not doing alot of production you can easily get
by on a foot operated bicycle pump. Most molds inject at 7-10 psi.
Or you can also use a storage tank for compressed air
that you can fill up at the local gas station . these cost about
25 dollars at any pep boys or hardware store.
