Compressor

Well,since im going to be doing alot of work on my classic,and the number one tool in a garage/shop is a compressor, i went and bought one today. it is not a commercial unit but should do what i want,or at least i hope so,its all i could afford.
Campbell Hausfeld 7.0 HP 60 gal,11.8 scfm @ 40 psi/10.3 SCFM@ 90 psi, 135 psi max.
Will it cut the mustard?
Now all i have to do is get it into the shop and hooked up in a corner someplace.

Should do quite well, better than what I use.

Campbell Hausfeld, like several of the lower quality lines is notorious for rating their HP as peak. Your 7hp compressor (peak rated) is probably at best a 3hp under load. Try and get an honest hp rating. Peak hp is virtually useless in picking a compressor.

302/Z28, i think you are right,But,i have it hooked up now and have been useing it,it kicks on and runs more than i thought it should,But it recovers pretty fast,i have yet to run out of air and i have tried every air tool i have out,DA sander,air drill,die grinder. I wish i could have afforded a commercial type compressor but this one will just have to do,once i get all the body work done on my car and start sanding the entire car i should have a better idea of how it will do.
im going to look for a good gravity feed sprayer with a good recovery rate,im thinking (and correct me if im wrong) that a good gravity feed will use less air and have a higher volume output? it should keep up,or at least i hope so,otherwise ill be in trouble. im a learner in this new hobby,and i guessing that i can paint in sections,but that its not a good idea if i can get away from it?
Ive done alot of reading but thats all you get out of reading,the real learning will start when i get to actually a "hands on" situation.

THere are also various grades of campbell hausfeld compressors from low to pro. I think their website has all the specs on it beyond horsepower, like air flow, and pressure etc. I personally have an old 10hp gas contractor grade compressor that will run a shop sand blaster all day... No down time with gas power. Some of the electrics have Duty cycles like welders, where it will run at this flow for this long then needs to stop.

Actually, it is a common belief that HVLP guns use less air, it ain't necessarily so.

compressors

Horsepower ratings don't really matter all you need to worry about is the cfm (cubic feet per minute) that the unit can deliver, also the larger the tank the more volume of air you will have whick will run tools longer between running cycles.

Horsepower ratings don't matter?

Support for my argument about peak HP vs actual HP.

http://aircompressorsettlement.com/index.php3

In industry peak HP rating is not even mentioned, because it is a useless figure.

I'm shopping for an electric compressor in the next few weeks. I want to use a die grinder to do some minor head porting, cutting of floorboards, and just blowing stuff around the garage for fun too.

My question is, what aspects of a compressor REALLY affect tool performance? What kind of CFM, PSI, and Gal tank should I be looking at for what I want to do?

Will 150 PSI max and 5.8SCFM @ 90 PSI keep the grinder spinning fast enough to not bind?
