  thats a ton of air just to be using it on a dozer here and there…im sure it lasts you a long time before it kicks in huh

  Basically, yes, you’re right. But when your using the impact, well that’s another story. Good thing I got this compressor, because I couldn’t run my impact otherwise. But, whenever I am painting a car, or the like, it does not run very often and does take a while to ‘kick’.

  even with just the head you should be able to provide enough air to run an impact. maybe not a 1 inch but 3/4 or half

  i have a 30 gallon with 9 cfm at 90 psi head it charges and runs air tools at the same time.. so in reality if your not using a large 1 inch to remove tires when i was working on tractor trailers for a living we only used a 80 gallon tank with 10 hp motor worked fine

  Try an inch and a half impact sometime! Most compressors cant even run one I tell ya. So yes, I’m using a huge inch and a half.

  is there any way to put something on it to shut the motor off when it reachs the max amount or air?

  @jeromeb619 Of course. And it has the apparatus on it to run it with a gas motor as well.

  Hi I am Peter from Ireland, let me say Im into all stuff mechanical too and you made a fine job of that Air Compressor, one thing though if I were you I would give the whole unit a lick of Oxide Paint (stops rust) then paint it engeneering Green, and as for working it in the fields you could mount a 4 stroke petrol lawnmower motor to it in place of the 1hp electric motor then it would be truely portable, nice work though

  @Oglaigh32 Well, first of all, It’s a 10hp motor not a 1hp as you have stated. And yes, I could mount a 10hp gasoline motor to it, but I do not think I will. Just having it hooked up like I do is plenty, especially with the 500 gal propane tank as my reserve. You can do a lot with it, that’s for sure.

  1 phase with that ? must be a lot of amps. to bad you dont have 3 phase. But you can get a VFD and that can take in 230 i phase you give you 3 phase but you have to mach it with your motor HP.

  sorry i mean 1 phase not i lol

  @67tr876 Well, there would not be much advantage to having three phase. See, the total power is what matters, and although it would draw less amperage, you would then have three phases. The only advantage would be wire size, but unless you have the three phase VFD mounted right next to your panel, you would gain nothing. See I am an electrical engineer, and am well versed in three phase, single phase power, as well as VFDs and power electronics.

  I think you need to keep things in proportion, so I propose that your next air compressor project run with a V8 mounted on top, with really loud exhaust. Perhaps then, and only then will you finally be able to power that badass impact wrench.

  @DavesTreeFarm It might be fun to do and become quite the talk of the town. But, I feel as it works fine the way it is.

  @67tr876 What exactly do you mean?

  @lectricgenius, I have done quite a few jobs in the field by doing that with my Craftsman compressor with a 30 gallon tank. You can’t run a die grinder or such high cfm tool for long on a 30 gallon tank, but it will turn impacts and air ratchet wrenches quite a few times around on one fill.

  Did you put a condensation drain in the bottom of the air tank? It’s important to drain water from the tank every day.
• 

  By lectricgenius, August 21, 2010 @ 12:47 pm

  @kd5gua Thanks man.
• 

  By lectricgenius, August 21, 2010 @ 12:49 pm

  No, I did not. I guess I didn’t have the time etc. I figure that if I drain the water out every week, that will be good enough.
• 

  By lectricgenius, August 21, 2010 @ 12:52 pm

  @borderraven Yes, it already had a bung hole, so I got that covered.
• 

  By borderraven, August 21, 2010 @ 2:00 pm

  @lectricgenius, put a petcock or small ball valve down there. Crack it open just enough to let the water out, but leave the oil in.

  btw — I only learned about this in the US Navy, because as a shop supervisor it was my job to check it every morning.

  By lectricgenius, August 21, 2010 @ 2:08 pm

  @borderraven The bung works just fine for me. I know all about this stuff and did not even have to go in the navy to find it out. I just wish everyone here on youtube would realize that I am no dummy, in fact I am probably smarter than 95% of the people on here. Yet, they feel the need to tell me stuff such as this, which I have known for years, long before youtube, the internet etc. I just wish people would realize this before they post a stupid comment.

  @lectricgenius, as intelligent as I think I am, I’m never ashamed to be educated, and happy to have educated others.

  Enjoy your shop works.

  By lectricgenius, August 21, 2010 @ 2:27 pm

  @borderraven I do not mind being educated either, in fact I enjoy it. The only problem for me is that I rarely, and seldom get educated by any of the comments that anyone ever gives me on my videos. See, I do not put a video on here unless I know 100% for sure that I know everything there is to know about a particular subject. The closest I can come to not knowing what I am talking about is in my videos about MS. But I feel that no one else knows about this disease either, doctors included.

  @animagus333 Go ahead, it’s not too hard actually.
