It might work. It would probably take you a while to use a da sander though. Probably not as long as mine POS. That compressor pump looks to be about 2 times as big as the I have. A dual action sander uses around 14 CFM @ 90 psi, but I don't ever run mine that high. Err that is when I had a compressor that could put out the air. 23 CFM @ 155 psi. The thing was just WAAAYYY to big to move it out of the shop it was in (Chehalis Wa).
If it ever goes on sale for $350. The 29 gal upright they (Harbor Freight) have would be the ticket. You wouldn't have to worry at all and could even have a buddy helping without worrying about running out of air. The main thing to look/ask for is "Recovery" time of any given compressor. Good luck searching and hope you find/get something that'll work good for you.

yea i was interested in that 29 gal even though it was a bit higher in price, But it says at the bottom it's for 220 volt applications.

I'm actually kind of surprised in the lack of selection of stronger compressors at harbor freight that dont cost 1000+ dollars...

I'll keep looking around, I'm gonna head into sears today and see if they have anything nice on sale.

well i went into sears, A Large selection of craftsman compressors in various sizes~but mostly in the 1-2hp range...

And on there biggest unit (60gal 3.2hp "pro") the cfm at 90 wasnt even 10... Am i missing something here? or are craftsman units really wimpy?

They had a 17gal 1.1hp 150psi craftsman on clearance for $175, cfm at 90 was 3.8 though...

You have got to pay attention to the CFM, and I swear they never put out what they advertise. I would consider the HF $369 the bare minimum for anything, and way too small for most things except painting.
If the compressor has to run constantly to operate an air tool, you might as well buy an electric tool. I have a 5hp, 80gallon compressor, and when I am porting heads and carburetor main bodies, it can't keep up with my die grinders. A D/A sander will use a lot of air too, but not like a grinder or impact wrench. If I was doing more work, I would update to a 7+hp 25cfm unit.

No, those Sears units won't work for you. More than likely you will need to get something that is 220volts.

I almost bought a 5hp/220v 80gl upright that pushed 23cfm @135 psi, (that's what the cutoff was set at) but it was sold out from under me. I gave the guy half down and wasn't able to get a trailer that day and somebody with a p/u came and took it before I could get back. At least I got my money back. The guys wife didn't know it was sold and he "claims" he wasn't home.
Anyway, my point is, you don't need a large hp motor to get the CFM require, you need one with a 2 stage compressor pump. My y compressor will at least run my 1/2" impact but not my DA.

All pressure and little CFM make for long work times with little accomplished. Whatever commpressor you get needs to be able to recover faster than what you use. That's what's called "Recovery Time". Here's a couple of pics of the compressor that almost was. :beatyoass:

Wow, That is a monster.
Sorry to hear it turned out like that... Very lame.

Yea, Ill stay away from the craftsmen compressors~I heard from someone else they make good ones, But i'm not impressed with the specs at all...

I need to hit up a few local puppies shops next, Hopefully i'll score something nice. :hick:

Ya, it was a monster. You, me and someone else could use that thing at the same time without it ever breaking a sweat. Good luck and hope you find something soon. I can't wait till I can get a better one also. I just need to get rid of some unused extra parts that I have laying around.

Well i've been shopping around, Nothing great so far.

Had a couple more newb questions though...
To get the desired SCFM, It's looking like i either need to spend ALOT of money, or go 60gal or more...

Am i missing something on this spec? Like when you say DA (Dual Action?) Does that mean you would be able to run 2 lines from 1 compressor and get more CFM rating out of it?

When i look at some of these paint sprayers and Orbitals, They require 14-16cfm@90PSI sometimes, And even in the huge compressors, they dont let out that much @ 90psi...

And this 220volt just keeps looking better and better to me:
http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=92504

But... We have an old house (1960's) and im unsure if this would require some special wiring? or if our wiring would even be able to support it?
I assume its just something like wiring 2 110v connections together into one 220volt receptacle?
Havent asked my dad yet either.

Or maybe even just buy some type of converter to run it?
**Found this on ebay, 3000watts should be enough to run at about 15 Amps right? enough to run the compressor (on low?), But whats with the 23.5 amp rating?... And also Not sure if the plug style would match the compressor but i could slap on a regular style hospital grade plug.
overall it would be alot easier than wiring for 220volt, this house... is... oddly wired.

Anyway, My search continues.

I won't go into "Weird House Wiring" as my house was built in to 1920's and has been rewired by someone who should've never touch a single wire let alone a whole house :( It's not as easy as connecting 2 110 volt circuits together. You need a dual 35 amp circiut breaker in your panel box to get the 220. But there are other things that need to be done also. Definitely ask your dad for help on the electrical work.
The DA I'm refering to is a Dual Action orbital sander, that means that while going in circles, it also goes back and forth.
No, hooking up 2 lines to a compressor will not increase the CFM output. Converters were not made to handle the requirements of a compressor. There is alot of "start up" or initial voltage used when the compressor fisrt starts. My lights in the house flicker slightly when my compressor starts. That's usual, well for my house anyway.
The way most compressors are sold, yes, it seems that you have to get big tanks. There are compressors made that don't have big tanks and put out big CFM too. At my old job, we had a compressor setup on a motorized cart for outdoor use that had a a CFM rating of 25 CFM @ 90psi and it only had 2 2 1/2 gal tanks, like the ones you see used for roofing or finish nailing. Anyway, like I said before, you don't need a big tank for the CFM you require. If you hook up 2 lines from the same compressor, you only use more air at a little lower CFM and a little less pressure. Sorry. If you don't find any 110 volt compressors that will work, then I would definitley recommend the HBF 29gl compressor. It will do what ever you need and then some. I'm saving for one now. Good luck :D

Thanks for all the answers and putting up with all my questions. :hick:

haven't taked to dad yet about the wiring.
But near where the compressor will be, There is 2 (actually 3, But i don't want to mess with the water heater)
220volt outlets... Both are in use of course, But doing some reading it may be possible and the most effective way to run that HBF compressor.

Outlet 1 is for the Dryer, And outlet 2 is for the downstairs stove/oven which we rarely use.
Obviously it would probably not be safe to run 2 items at the same time off one outlet, But plugging and unplugging the compressor and other item is better than a wimpy/no compressor at all. :D

The length of cord to the carport would not be anymore than 15 feet, However it may take awhile to find some end plugs for the compressor that fit into the 220v outlet... (very old and odd shaped 3 pin plugs)

I can actually get a voltage regulator on ebay for 5000watt, still may not be enough though (25ax220v=5500watts, And adds another 100+ to the cost.

I'll talk to dad, And hopefully we can work something out.
That HBF is insanley good for that price compared to all the compressors ive looked at recently... :hick:

No problem with all the questions :) Glad to help
Yes it's a good compressor for that price. I would draw the way the plug is on that odd outlet and go to an elctrical shop and they can help you. Don't go to an home improvement store, although they may have one as well, I kind of doubt it. Unplugging/plugging between the compressor and your down stairs oven sounds to be the better route to go also. Good luck and have fun.
