actually, if you put a 1/4 HP motor on it (with proper reduction) you
would have a much better compressor than one of those buzzy little

(thermodynamically) compressor

Quiet, too.

Curiously, my Quincy got QUIETER when I upped the motor. It came with
a continuously-on motor and pneumatic unloader, and a 1 Hp motor. The
pulleys were set for something like 450 RPM.
I got a 2 Hp motor and changed the motor pulley to get 915 RPM and
rigged controller to use both unload and motor start/stop as the demand
required. The surprise is the compressor was quiter at 900 RPM than 450.
My guess is the intake valves were pulsating at 450 but go full
open at 900.

'Could also be a 'resonance' thing.

It probably depends on the preferred RPM of the compressor in
question, too. I'm sure Jon checked that out before upping it.

What's more dangerous with gasoline vs other petroleum solvents?
All are flammable, some have lower vapor pressure but will still
burn.

I use gasoline outdoors, in small quantities, like 1/2 pint.

The problem with gasoline is that it produces a lot of vapors, unlike
some heavier solvents. Parts washing solvent, for example, produces a
comparably negligible amount of vapors.

Yup. It looks like the check valve is even made to be maintained, so I
may be able to fix it without either total disassembly or buying

purchase has inspired purchase of spray guns, hoses, etc. -- I just need

It's a cheap little compressor, so I'm pretty sure that the "unloader" is

.... and with a ball _in_ the check valve, it works just fine, even though
it keeps leaking from the compressor head (the ball came from a toy, so
while it's steel and shiny, it's probably far -- or far enough -- from
being a perfectly round ball bearing).

When I bought it I made sure that it got plugged in and came up to
pressure. What I _didn't_ do was bleed off some air and make sure
it started again -- which it doesn't. It tries, but the thing don't
turn. I thought "this thing needs a blow-down". Then I heard the
slow leak from the compressor head, deduced the existence of a check
valve, and found the check valve. Presumably it just needs to be
're-checked'.

Oh well.


If it runs and pumps, the rest is fixable.

Yup. It looks like the check valve is even made to be maintained, so
I may be able to fix it without either total disassembly or buying
replacement parts -- this is a good thing, because the compressor
purchase has inspired purchase of spray guns, hoses, etc. -- I just
need a regulator and to clean up the nice used guns I bought, and I'm
ready to paint.

Thats what it sounds like.

Unloader stuck?

It's a cheap little compressor, so I'm pretty sure that the "unloader" is
an intentional leak in the compressor head and the check valve.

I respectfully disagree with Iggy, but if the check valve is doing it's
job I may well come to agree with him.
On my home brew set up, the unloader is incorporated in the pressure
switch - 1/4" tube runs from the input side of the check valve to the
side of the switch where a tire valve is pressed open when the switch
turns the motor off. At this point there is a hiss as air is released
from the plumbing between the compressor and the check valve. I can
press the little lever down to release pressure if I switch the motor
off before the tank is up to pressure. Some pressure switches manually
shut off the power by mechanically opening the contacts independent of
pressure.

My friendly mechanic donated a 1/2" ball from a dismantled bearing to
replace the corroded ball which serves as the outlet valve on my
little Gardner Denver.

Sounds like two different problems. One, the check valve (now that
you have one...) still isn't sealing. Hence the leak-back and
hissing, and the hard starting.

Most of those valves either have a hard poppet with a soft seat, or a
hard seat and a poppet like a little torpedo with a soft sealing face
washer on it. Hard seat and hard ball isn't going to do it.

Look up the generic compressor check valves on McMaster or Grainger,
they're cheap and easy to replace - the hard part is finding the right
combination of NPT threads on the tank end and Flare or Compression or
NPT on the compressor end.

Two, there should be a mechanical unloader valve on the pressure
switch, with some 1/4" tubing between the unloader and the output
tubing before the tank check valve.

You might even be able to fix yours on the cheap. It's a Schraeder
tire core for the valve.
