Is this compressor worth anything?

Offer this guy 50 smackers for his Quincy:

the motor with a 2 HP 1 phase and be happy for a long, long time, would be my advice.

$50 is actually pushing the "play" budget a bit, it's just that I'm getting damn tired of rattle-can paint jobs. So $50 + a motor is a bit hard to swing, unless I can trade the 3-phase motor for a 2-phase, or unless there's a _cheap_ and reliable way to cobble it up with start caps and run at reduced HP.

I was looking at this, too, but without knowing where it's been it's hard to know:

That looks like a dentists compressor.

Look at some of the very small compressors from the cheap auto places and use an old Propane tank for a resrvoir?

I've picked up several compressor motors of that style that were not putting out much air until the head had been removed and the reed valves cleaned, didn't need any new parts and aren't real complicated, just be sure to reassemble correctly (hopefully some one else has been there already and mis-assembled it).

Just a tip - if you go to look at it, pick it up off the ground a little bit and kind of wobble it back and forth, if it seems half full of water that may give you a clue as to whether to get it, or a bargaining point if it feels like it's got water in it.

Very funny!

I have a 10 HP Quincy and I paid $200 for it.

I picked a nice clean unit (probably less than 12 months old) from the hard junk verge collection a few months back.

I pressed the reset button on the motor & away it went. Runs fine!

It's a nice little wobble-piston oilless that should be plenty for a homeowner. You can get parts for it if you need to, the head is either Gast or Thomas or Speedaire. And check the tank for signs of huge rust or pinholes - you don't patch leaking and rusted-out pressure vessels, you replace them. (Or try to sell them off to someone else.)

Forget the big 10-HP 3-Ph unless you're planning to work on cars and need that much air - you would need at least a 7-1/2 HP single-phase motor and a sheave change to use it at a residence - or a rotary phase converter. Forget a static, they don't put out enough power.

And the third one looks Real Rough. Wouldn't even think about it unless it's hooked up and running.

This one certainly wondered about valves and rings!!

And I hadn't noticed the lack of guards, but that's a good point. It could be retrofit -- at the cost of time I'd rather spend doing other things.

We all need to think more like Iggy, Tim:

Iggy: Very funny! Iggy: Iggy: I have a 10 HP Quincy and I paid $200 for it.

The real answer is to buy the Quincy for $50:

1) Invest some sweat equity to clean it up and test it. 2) Offer it on eBay for say $1500: Buy a few decent compressors with the profits.

And spend the price difference for earplugs. :-) Good belt driven compressors are *much* quieter in operation than the oil-free ones.

Unless you mean the really small ones designed to pug into the cigarette lighter socket (if you still have one) to refill tires on the road. And those take forever to move much air. Totally useless for painting. :-)

Enjoy, DoN.

What I found funny is the idea of putting a 2 HP motor on a 10 HP QUincy.

yep...

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 things - in fact a old "free' washing machine motor will run it just fine, just well below capacity - that will be a very efficient (thermodynamically) compressor

He needed 40 PSI. That would have done it all day, all night. Even if it required a jack-shaft to adjust for lower RPM at sufficient torque: http://209.85.48.9/2428/142/upload/p3275451.jpg

I like the second idea better too.

Quiet, too.

They are certainly noisy - Once I forgot to turn mine off at the power point, I'm sure the neighbors were impressed with it coming on at 3am when the air leaked down. Had to drag myself out of bed to shut if off.

I was thinking of the small ones for running airbrushes. Your'e right about the tyre compressors - all pressure and no volume.

A 10 HP Quincy compressor is no less noisy.

At 350 RPM, the Quincy would be quieter. Cleaned and sold, it would be *much* quieter. :)
