Pissingintowind posted:Is there any air compressor worth buying at HF? Or is it better to stick to the more known brands? The first two things you list require pretty low air flow for a compressor, that impact wrench is a 22CFM beast that will be limited by basically anything less than a shop air system. What I'd do is get a cheap HF compressor and hook a spare tank into the line to keep psi up. You'll only get bursts at high CFM, but it will be a lot cheaper than a huge compressor.

The problem with those sets is they include a lot of duplicate sockets and the quality is always rock bottom to keep costs down. That set has 12 sockets to fit a 7/16" bolt. Hit up harbor freight and grab a socket set, breaker bar, extension set(just toss the extras), screwdriver set, and a tool box. Total cost, $60. oxbrain fucked around with this message at 20:58 on Apr 30, 2009 |

Use your torque wrench to torque a different bolt to the correct spec. Turn it slightly with a box wrench to get a feel for what the correct torque feels like. Torque with the box wrench. What is the torque spec on those? I'd be willing to bet it's a huge spread that could easily be hit with a box wrench.

I think he's talking about a cable saw. It's a string you run around a tree branch and pull on the handles to saw. They make them that can handle metal. A sawzall would work a lot better. That HF one is only 4amp though. this one would be much better for the price.

You might have ovaled out a sleeve bearing or pivot shaft. Go up too high and it binds and grinds, at some point coming down it will pop back. I'd throw some oil in any pivot you can get to and wait for the jack to go on sale again. It's not a $400 serviceable jack, it's a $70 throwaway.

Keep in mind, your compressor doesn't need to actually do 20cfm to run a 20cfm tool, that's the whole reason for having an air tank in the first place. A 60 gallon tank will take up the least amount of floor space and give you plenty of air to finish a single body panel with even a tiny compressor. It's also a common enough size that you can find them on craigslist all the time for pretty cheap. I would look for something with at least 50% of the rated CFM of whatever tool you're using.

You might be better off ceramic coating them if thats within your budget. The wrap traps heat, higher heat means faster corrosion. Unless the ceramic coating is completely sealing off the metal it will do the same thing.

What's your budget? Accuracy costs money. The HF wrench should be close enough to be within tolerances, you'll be spending $80-150 before you get much better. NAPA will sell you a wrench for ~$200 that will be plenty for any car related work.

Nerobro posted:For all of my paintball stuff I use the female connectors on the hoses. Is there a standard? Is it all female going towards the air source? Female connectors have valves that close when you decouple, so put those on the source side. So the tank gets a female, hose is male->female, tool is male. Otherwise when you disconnect a tool your hose goes flying around.

Cat Hatter posted:Also, just to be sure, when Harbor Frieght compressors break, they just stop working right? Just don't want something that's going to blow up my garage one day. I would be stunned if a HF compressor pump could hit high enough pressure to rupture a tank. Even if it could, there are burst discs that will blow long before the tank does. If it does manage to kerplode your garage, you've got a gigantic lawsuit against them. I wouldn't buy HF compressors simply because a good, used compressor will be better for the cost. For the same 5hp their pump will do 13cfm@90psi, my 20 year old speedaire will do 16, and a newish quincy/CP/IR unit will do over 18. All that wasted energy goes to heating up your air, which means more condensation. Used industrial brand>new consumer brand>used consumer brand>new HF>any oilless compressor.

You can't hurt an air motor by overloading it, so turn all you want. 3/8" line is required for the airflow for max torque. It will run fine on 1/4", but you're giving up 10-25% of your power. edit: 1/4" npt fittings can have an inner diameter of 3/8".

In that price range I'd just look for oiled and not harbor freight. edit: Might be a little underpowered, but that is the exact pump I have that is quieter than my fridge.

I should just make an air compressor help thread. A couple things, 1. My guess is that you have a cheapish(not $2000) compressor and are using the on tank regulator to set your pressure. These regulators are notoriously poo poo, give poor measurements, and don't flow for crap. On really lovely compressors it's common to have a 1/8" line running to the regulator and a 1/4" coming out. The simple solution you've already figured out, set the regulator for higher psi and the increased pressure will compensate some for the lack of flow. Don't go too high or you could damage the gun or the trigger mechanism. The reason those huge impact guns work so well on a lovely compressor is that you get at least one good belt in before the line pressure drops. That first hit knocks the nut free, and it spins off easily with lower pressure. This is also why it sometimes works better to do several short bursts on a nut. 2. An impact wrench that's rated for 250ft-lbs can tighten a nut to 250ft-lbs under ideal circumstances if you let it hammer away for a couple minutes with all the air it could ever need. Or it can't and the advertising team just made up some bullshit number.

# ¿ Dec 4, 2009 00:28 |

Better regulators aren't that expensive. $30 will get you a nice one. Metal body, built in gauge, +-3% psi, and plenty of flow for minimal pressure drop. These don't come on consumer air compressors because it would turn a $100 compressor into a $115 compressor and they'd lose some sales. Consumer compressors make me angry.

# ¿ Dec 4, 2009 02:26 |

In place of. The stock regulator should be screwed onto a pipe coming out of the tank. Ideally that pipe should be 1/4" or 3/8" NPT, you can easily test this with some pipe fittings from the hardware store. If so, get some pipe sealant(don't use teflon tape) and screw the new regulator down just tight enough that it doesn't leak under pressure. There will be an arrow or something on the regulator to indicate flow direction. The other end gets a female quick disconnect and you're good to go. Of course, the pipe coming from the tank could also be 1/8" NPT, some random chinese threading, or even a flare nut. If it's 1/8" NPT you can get an adapter, otherwise you're screwed. Some consumer compressors also run the motor start/stop switch off the regulator because their reckless fucks who care more about saving $2 than your life. If there are any wires going to the regulator then you're screwed. By the way, 1/4" NPT has a nominal inner diameter of around 3/8". 3/8" NPT has a nominal ID of around 1/2". That's why your fittings are all 1/4" NPT but you need 3/8" hose.

# ¿ Dec 4, 2009 03:47 |

The easy way to test for proper flow is to attach a gauge to the tool with a T-fitting and see how much pressure drop you get under load. Set the regulator so you see 90psi under no load. If you pull the trigger and it instantly drops to 60psi then you've got a problem. You'll always have some drop, but you want it as small as possible. Realistically on a cheap gun like that if you can start at 100-110psi and wind up around 90 then you'll be fine. Worst case scenario is you break the gun. If you break the gun you can buy a bigger one that will remove nuts in the first 1/2 second and all will be well. Wagonburner posted:The regulator is a weird looking bastard, I noticed the tank has a big 1.5" or 2" pipe plug in the side, could I take that out and put some kind of regulator there instead of hacking up the plastic cover to replace this strange looking thing? (return it to factory config easier to sell it later) That would be an inspection plug most likely. Messing with it could be dangerous. If a 1/4" fitting lets go you get a small projectile and a loud hissing. If a 2" fitting lets go the whole tank could go flying. The plug holds so it'll hold pressure, but how well will it hold up to you tripping on a hose and knocking it over? Just something to keep in mind. My compressor has no regulator or outlet on top, just the pressure switch. There is a 3/4" NPT bung welded onto the side of the tank and you either attach a regulator or plumb it into a larger system. You have 4 options. 1. Crank the stock regulator wide open and install a second one downstream. This could wind up being worse than just the stock reg. 2. Leave the stock regulator alone and plumb a fitting into that 1.5-2" bung on the side of the tank. This could potentially explode. 3. Remove the whole regulator and switch assembly and replace it with new, standard parts. This would cost about $150 and could explode if you do it wrong. 4. Get by with the stock regulator until you can afford a compressor that doesn't suck.
