Awl--

First, a gloat-- I got *four* Quincy compressors! :)
Now, the ungloat:
All are in various states of disrepair. <sigh> :( :(
The goddamm pulleys weigh 45 lbs each!! (dual belt)

But, apropos of a previous post on motor rpm, starting load, etc, how do you
know if you have "unloader valves"?
Are these part of the compressor, part of the regulator assembly? Can
something like this be added?
What is that loud "CHOW" when the compressor shuts off? Unloader valves?

On "real" compressors, like my buddy's millenium old Kellog-American, the
regulator has two springs, one for low pressure start, one for high pressure
cutoff, so you can, among other things, vary the duty cycle, it seems.

On budget compressors, like my HD Husky (which I still like--cast iron, oil,
QUIET!), the regulator has two springs, but they appear to be simply two
springs in parallel, which raise/lower start/stop pressures together. Is
this correct?

What I did, as a sort of prophylactic electrical hedge, was 1. wire the
motor for 220, and 2. remove the motor from the regulator start contacts,
and instead put the motor on a decent sized relay, so at least the regulator
contacts don't carry that high inrush current alluded to previously.

I also took off all that belt shroud crap, so the spokes of the pulley act a
little bit like a fan on the compressor housing.

Pulley/belt/blade guards are for shop sissies. :)

If I had my druthers, I'd have a shop w/ one of them ancient overhead
belt/pulley systems.
Now DATS a shop! :)

Exrtrapolating from well pressure-switch knowledge, one of the springs
might only contact whatever moving part is in there when its close to
shutting off.

On my well switch, one spring adjusts at the same time the "on"
pressure and the "off" pressure, the other one acts like a 'booster-
spring' to affect only the off pressure.
