Compression - Show Off Your Compressor

[Mr9two9]

I just picked up this, and an oxy actelene setup from a guy on cl. I had to separate the pump from the tank to fit it in the minivan to get it home. It will go under my porch, on hockey pucks /threaded stock drilled into concrete. Also got a funky splitter/ dryer setup. Gonna need you guys help for the wiring, as my box is about full. I thing its setup for 220. Guy had a shop in his garage from previous owner.

Here is my Quincy 310. 60 gal. 1964(date on tank) Bought it from an old gas station. Took it apart and cleaned and painted it. Replaced all the bolts, tubing and wiring. Every where there is metal to metal contact, I have put rubber pads or sheet between. From empty to 140psi takes 12 min. Just wired in the breaker and recp. this past Tues. 06-14-11 . Have yet to run the piping.


Hockey Pucks


Runs so quiet. Sounds like the African Queen.

No compressor to show off, but wanted some opinions. I was in Harbor Freight today and they have these two models:

I do not have 220 in my garage so that sort of limits me at this point and not in the near future upgrade list.

My needs are to run my impact wrench for the car, truck, trailer wheels, some small tools , etc. Would these suffice for my needs? Anyone own one and how do you feel the quality is for longer term. I know some of the HF stuff can be junk, but then there are the tool boxes that are pretty decent for the money.

Thanks.

I would spend the extra $150 for the 68127. There is a huge difference in these two machines.

The cheaper one (67847) is a direct drive single piston pump so it runs at motor speed. In this case that's 3,400 rpm and 3,400 compression strokes per minute. I expect it's going to sound like a 50cc dirt bike at cruising speed.

The more expensive one is a belt drive two-piston pump that appears to run at about 1/4 motor speed. For the same motor, that's 850 rpm -- but because it's two cylinders, it's still giving you 1,700 compression strokes per minute. It probably gets its higher CFM output from a longer stroke. Expect it to sound more like a lawn mower at idle.

Thanks Bob. I was leaning to the more expensive one. I just put the two up (I skipped the "oil less" ones as everyone has said steer clear of them) to see what everyone thought. They also have the bigger ones that require 220.

No issue doing what I need though? My little nail gun compressor cannot even tighten a lug nut.

The tools you want to use need PSI rather than CFM. Once your tank is at 150 psi, your impact wrench should work just fine. You will be waiting for the compressor to catch up if you are breaking free all 20 lug nuts in a row.
You will have the same problem as the rest of us. The compressor is handy, the air tools are cheap and you'll find more things that need the compressor. Don't go overboard on this one because you'll want a really nice one when you do upgrade and have the 220 outlet installed (probably the same time you decide to get a welder).

Champion- Not real cheap but 100 percent made in the USA.

My new Quincy 7.5hp. It makes some serious air!

My home made compressor made out of a mid eighties Chrysler rv2 ac compressor.

Nice Quincy and Champion.

Neither did I, $80 for cable, $5 for a breaker, $8 for a box and an outlet and a few minutes on here doing some research and I was ready to go. Cost me less than $100 to run the cable and add the new breaker. NBD.

[PDACPA]

89GLH - you are way braver than me! I will install lights and swap out switches and plugs, but I am a bit out of my league when it comes to the BREAKER BOX! Though seeing how cheap the parts are, I do have a buddy who is a GC so maybe a 6 pack and everything all mounted, he can dig around in my box and make the connection!

Brought this guy home saturday - 1996 SpeedAire 5v401b - it's a 10hp 40cfm 4 cyl 2 stage pump. It was a real too good to be true deal, but I took a risk on it and brought it home.





Alas, pulled it apart and found that someone ran it for a loooong time either full of water or without oil. Spun rod bearings on all 4 rods.







Only put $100 bucks in it, should be able to recoup my loss selling the tank and motor (3 phase, so unless I want use it as the generator in a rotary phase converter, it doesnt do me much good at home...)

Got a good set of heads and lines for the 5v405 pump, if anyone needs them, too.

1971 Hill bros. compressor.

[bobadame]

Here's my old compressor. Still need to plumb air lines through out the shop.

[PsRumors]

Here is mine. It came out of the Coke restoration shop in Atlanta. Haven't been able to find anything about the company so I assume it is either a rebadged pump or chinese knock-off. Either way it does pretty good providing 15.5 CFM at 165 PSI (per my calculations).

And for $500 who can complain.

Nice! I wish I had gone with that one. I bought the Quincy model right below that one

If the tank, motor, pressure switch, etc are still good, why not spend a couple hundred on a new pump?
