If you're going to blow a computer out with it, you really should get one of those water/dust separators for it. You would be shocked by how much water, oil, and miscellaneous crap ends up in the filter bulb after a few hours of use. Also great to have around for running HVLP guns, unless you like millions of fisheyes in your paint.

Since I went ahead and started getting ahead of myself and received some extra Christmas money, would the 2.5hp compressor power tools for garage level use? Mainly a angle grinder with wire brush for rust removal, ratchet, etc? Because why spend $40 on what you need when you can spend $140 on what you want.

Check the continuous CFM rating of the compressor vs the tool. Cut the compressor rating in half and double the tool rating and you're in the realm of reality. In general, a small compressor with a 20 gallon tank will run something like an angle grinder for way less than a minute. Then you'll be waiting for however long it takes to fill the tank again.

I bought the biggest compressor (60gal) at Home Depot for light use and I was surprised at just how much it cycles. Running my HF sandblaster causes it to run almost constantly.

What usually amaze people is the required tank capacity to efficiently run tools. 60 US gallons equals roughly 230 liters though. Should be enough for running almost any tool, and definitely enough to run a sandblaster. Something other than capacity is wrong.

Sir Cornelius posted:Something other than capacity is wrong. Low CFM pump that takes forever to catch up/refill. Most of the ones I see at home depot have a motor/pump that would be appropriate for a 30 gallon setup on their 60 gallon units, and little more than a 12v tire inflator wired up for 120v on their 20 gallon units. People don't know/don't care because it's cheaper. Until they really try to use the compressor for something and realize why the 60 gallon 240v IR costs $3000 and is worth every penny.

I can run it constantly so I don't think there's anything wrong, it's just that the compressor pump kicks on a lot to keep the pressure up. I can still run the sandblaster 100%. E: 11.5 SCFM @ 90psi / 3.7 hp 2-cylinder 240 volt. revmoo fucked around with this message at 18:21 on Dec 30, 2012 |

So that could pretty handily explain why your compressor runs constantly. Edit: and the IR 240v 60 gallon 5 HP is rated at 18 CFM at 90, which is why it will run that cabinet without constantly being on. Motronic fucked around with this message at 19:15 on Dec 30, 2012 |

Maybe not a tool, per se, but I guess I found out a much better way to remove old tint goo from windows and other sticky stuff. First, open up your cabinet and pull out that trusty old bottle of Goo Gone. Then, take a garbage can, any old one will be fine, and fuckin' throw that poo poo in there once you realize how much better 3M Adhesive Remover works.

Gah, screw it. I'll just get the $40 one for filling my tires. This happens every time I think about getting some air tools. It ends up that I need to spend $800 and have the garage rewired just to break some lugnuts free or do what my $8 HF electric angle grinder does. By the time I'm in a position to do that I'll have enough electric tools that I won't even need a drat air compressor.

Your cut-in/cut-out pressures may be set close enough that the compressor is trying to keep it within a narrow window. You can probably adjust your cut-in pressure to be a bit lower, then it will run less often, but for longer each time, with the same end result.

It ends up that I need to spend $800 and have the garage rewired just to break some lugnuts free or do what my $8 HF electric angle grinder does. I sort of know where you're coming from. I got a small cheapish compressor early on just to run a small air nailer and for filling up tyres. It was really handy but then I thought I'd like to do a litle spray painting, this wasn't up to the job so I then got the largest compressor that would run off a 13amp socket. This worked fine for spraying and general use, although would severely run out of air on my cut off saw. Eventually I wanted to do a bit of sandblasting as well as spraying whilst using an air fed mask (spraying 2k ). This wasn't up to the job so I got a petrol compressor with a honda 13hp motor on it. This is terrific for certain jobs and nicely runs the air tools I have now. I use them at different sites so having a big electric fixed unit wasn't an option. The point i'm trying to make is for the time being a cheap little one will do fine for inflating tyres and may spin up an impact gun but it will be slow going. It also has the advantage of being portable. Then in the future you can get a good sized compressor when you feel the need.

Tomarse posted:I've broken 2 of the 1/2 inch machine mart ones. One took me jumping on it and just deformed really gracefully and one took a 6 foot scaffold bar and snapped suddenly. Didn't know they did a 3/4 too - I shall upgrade! I still rate Halfords Pro tools over nearly everything else (Barring real pro stuff like Snap On etc). Get a trade card and the price is genuinely competitive. That said, I've had quite a few mechanical weekends recently which has prompted me to buy a few things that, now I've got, I couldn't be without. Especially for the UKers, and in order of my perceived importance: 1. Impact Stud Remover http://www.machinemart.co.uk/shop/product/details/tool-connection-tc3986-impact-stud-extractor?da=1&TC=SRC-laser+stud This is the kind of thing that I've struggled for years without, preferring to buy spanners and sockets over 'gadgety' type tools. I got away with it for so long, but found myself staring at 4 broken, rusted in, studs one weekend. Can be used with an impact wrench, too, which brings me on to... 2. Electric Impact Wrench http://www.machinemart.co.uk/shop/product/details/clarke-cew1000-electric-impact-wrench?da=1&TC=SRC-clarke+electric+impact Something I've wanted for ages, but just couldn't justify the outlay. Finally succumbed and, my, what a machine. I don't have the room for any kind of air compressor and I don't like the idea of annoying the neighbors with constant noise This bad boy will strip and sheer bolts at rates that simply can't be achieved by hand. It has the advantage of being capable of 450Nm - it's drawback is that it's really quite heavy and very bulky. Forget getting into tight spaces. But, I've done some terrible things with that torque..! 3. Gear Puller http://www.machinemart.co.uk/shop/product/details/clarke-4-piece-gear-puller-set-cgp4?da=1&TC=SRC-laser+gear+puller Like the stud remover, for the price I should have got these years ago but, y'know, why spend money when a hammer and persistence will do the job! Haven't had a huge amount of use out of them, but they've been invaluable when required. 4. Reciprocating Saw http://www.machinemart.co.uk/shop/product/details/clarke-con850-reciprocating-saw?da=1&TC=SRC-clarke+contractor+saw Although last in the list, this is actually my favourite. I was changing a pair of lower wishbones on a 15 year old car - the bolts just rounded on me and my angle grinder was stuggling to get into them. I'd actually changed tactic and had simply started cutting the wishbone, but it was killing my grinder and it kept "snatching". I was actually in MachineMart looking for new discs when I asked if they'd got an alternative. Although I can't see me using it very often, let me set the scene: I spent 3 hours in the freezing cold battling with an angle grinder. This thing came along and the car was road worthy within 90 minutes of starting. It's fast, accurate and downright destructive.

Blackdawgg posted:I plan on getting something more serious whenever I buy a house. I thought about the 2HP model from Harbor Freight but since it's oiled I can't use it to blow out my computer. It's not really big enough to power any air tools I don't see the reason to spend $100 I've cleaned out my computers for years with a standard pov-pack 2HP compressor. I assume it's oiled because I dumped a few hundred mL of oil into the reservoir like it told me to about 5+ years ago.

Just for taking wheels on and off it's worth the price, but it will come in handy more than you can ever realize.

spog posted:Is there a difference between impact drivers and wrenches? Yes, impact drivers have far less torque and sometimes apply a downward force in addition to a rotational one. I've always understood that they're meant for installing screws and such in a quick manner. Notice how that one has a locking hex drive, not a square 1/2". Even if you could get a bit to work with wheel nuts it wouldn't do squat, 150Nm is only 110ft-lb, and it's never going to function at that anyway. If you want to work on a car, you need a 1/2" drive impact. The higher the rating, the better but I've been fine with 220 ft-lbs for most work. Exhaust, wheel nuts, flywheel bolts. Actually, that's another reason for an impact. If you have something that rotates freely but is held in with a nut (my e36 top strut nuts come to mind) an impact will get it off without having to retain it. Especially handy when you've got something like a shock where they give you 6mm flats and an M10 nut. Good luck getting that off with hand tools.

This might be a better fit for Alternative Insanity, but I'll ask here since we are deep in Compressor Chat. I have an ancient Emglo gas powered (Wisconsin Robin engine) compressor, and I really need a new pressure control valve assembly for the compressor. Mine works, but is so worn that I can't really trust it to function correctly, it seems to be 50psi or outside the pressure relief in 1/2 turn of the adjuster. The valve threads into the tank with 1/4" or 3/8" NPT, has a line going to the compressor head to engage a bypass, and tees to a throttle control actuator, which works fine. They're always missing from the compressors at the scrapyard, its not fair! DJ Commie fucked around with this message at 19:19 on Dec 31, 2012 |

Went to the junkyard today and realized halfway through pulling Honda brake/wheel bearing parts that both my 13 and 14mm Husky impact sockets are actually 13mm.  Apparently someone put a 13mm socket forging into the knurling/label stamping machine by accident a year ago when I bought this socket set. First problem I've ever had with a Husky tool (aside from ratchets) that didn't involve a six or seven foot cheater pipe.
