Harbor freight air tools are not crop. I've got their 1/2 impact (earthquake), die grinder , angle die grinder, needle gun, etc. All work great and were cheap. The only complaint about the earthquake impact is that it's heavy and loud as hell.

I'll agree with the "not crap". I have several. I think they get a bad rap for losing power because they are often baby's first air tools and aren't lubricated properly by the uninitiated.

Most of them are pretty big for their power output, so it makes tight spots more difficult than with tools that cost 4 times as much.

Can you tell me about proper lubricating for baby's first air tool then?

When you first get it, turn it upside down and fill it with oil up to the top of the air fitting. Now squeeze the trigger to let the oil run into the tool. Hook it up to the air hose, point the exhaust at the ground/away from you and run it until no more oil flies out.

Now just add a few drops every morning before you use it. You don't need to add so much that it runs out every day.....you'll get the feel for it. Each tool is a little different in how much it takes.

If you don't do that they either sludge up or rust from the condensation in the shop air supply.

I literally had no idea I had to fill it. Thanks!

Does this mean I need to take the fitting out that I screwed in and then fill it?

I knew they had oil lubricating them, as it sometimes comes out of the exhaust.

Which oil should I be using?

Nope, fill it to the top of your air fitting. No need to remove it.

As far as what kind of oil, "air tool oil". The have it at HF and pretty much any place that sells air tools. It has a squeeze top on it that fits right in the air fitting so it doesn't make a mess.

Ah, okay. For some reason I had it in my head that I would be filling the whole loving gun. But just fill it to the top of the air fitting, attach it to the hose, then add a few drops every day. Thanks!

Yep. Just to the top of the air fitting on that first fill or after a rebuild (or after it's been sitting for months) to make sure you get it really lubed up. It's really not that much oil....you aren't filling the whole thing, just up to the valve. Then when you press the valve it dumps in. Then hook up the hose.

Only reason I wouldn't put it directly on the end of my air hose is that I don't want to fill my tires with air tool oil.

Which you will even on a quick disconnect because the inside of your hoses will be loaded with oil.

I've though av the same thing, but keep going back to a big no. The only way I'd do it would be to have a separate air tool hose/hoses and manifold the "air only" ones back behind the oiler.

kastein posted:

That's what I mean. Basically an inline oiler with disconnects on both sides, that I insert between the air hose and the tool. If I'm wanting just air, remove it, and connect my blowgun/tire filler/whatever directly to the hose.

Maybe I'm misunderstanding you or I wasn't being clear.....if you run a hose in front of an oiler, even after you remove the oiler the hose is gonna blow oil on/in everything. You'd need separate air hoses to pull this off.

Splizwarf posted:

He's talking about Compressor -> Hose -> Quick Connect -> Oiler -> Short Hose -> Air Tool. The short hose goes away with the oiler when that's disconnected, and is the only section of hose that gets oil in it.

I guess the only oilers I've seen are absolutely mount-it-to-the-wall type deals, so I don't see how I'd set one up other than at the manifold. That and I use retractable hoses on the ceiling.

Yes, I am aware that they make more than one type of abrasive. The problem isn't with type, it's with abrasives period. That's not how it should be done. Plastic scrapers and chemical help followed by razor blades if necessary is how you do it without risk of damage.

This. Using plastic bristles on an angle grinder makes using a razor blade seem like the stone age. It's good for anything where you need to remove crap without damaging the surface metal.

Except I've seen aluminum surfaces ruined by even the white (lightest) bristle discs. Have you noticed that no matter how lightly you use one on aluminum it still ends up leaving swirls? That's missing metal.

You may get away with that just fine if you are exceptionally careful, but you are really asking for problems especially with bimetal engines and MLS gaskets. I "repaired" one for a friend that failed to do excessive scotchbriting by coating the new gasket with Hylomar (which I can't even find locally anymore - Permatex used to sell it so it was in most parts stores). That's what I consider an atrocious hack job, but it worked for a few years at least (truck has since been sold).

I get it, everyone wants a faster and easier way. I do too. But I won't do it to the detriment of doing the job properly. Sharp razor blades at very low angles and solvent get the job done without risk of damage, so I'll be sticking with them until I see something better that doesn't remove metal.

How much impact does it have on engine power? Does it reduce power output at all?

It didn't do anything that I could tell to my 5k generator. Brigs motor, so it's still noisy and clangy because the internals on those motors sound like you're throwing a box of silverware down the steps when they're spinning, but at least very little exhaust noise.

So, before I get at it, are there any secret techniques to helicoil thread inserts? I have a couple of stripped M10x1.25 bolt holes for a sway bar bracket, and the helicoils look (deceptively?) easy if you're patient and don't try to do it from a weird angle. Any advice appreciated.

The only "secret" to helicoiling is knowing how to properly cut threads. This means your drilling and tapping MUST BE STRAIGHT. Yeah, I don't care how good you think you are.....it's not gonna be straight by hand. If being off a bit is OK for the application, go for it. If not, make a guide so you know you're straight. Wait...you don't have the facilities to make a template? Yeah...not all helicoil jobs are easy....sorry.

For a sway bar bracket, chances are good being off a bit isn't a big deal, so you're probably going to be just fine with a cordless drill and a helicoil kit. Don't think you can do the same thing for head bolts, spark plugs bores, and bolt holes for flanged joints and you'll be fine.

I picked up an INNOVA 3100 and it's all I'd ever need. Gives you the code and description on the screen and was under $100.

What would these advanced ones do? Sensor voltages and data?

BCM readings and controls (vendor specific and usually very expensive), ABS readings (same as the last), freeze frame data (Mode $06), IM readiness status (Mode $03), live data and the ability to log and graph it over time.......

pretty much everything that makes OBDII useful as a diagnostic tool, and why I don't even both with readers anymore and just use a laptop (I have one of those cheap little netbooks just for the purpose) because it's enough data that you really do want a keyboard and mouse and the ability to do useful things with it.

If you don't know what one or more of these things are and are serious about wrenching on 1996+ vehicles it would be a very good idea to get familiar. OBDII is a lot more then DTCs, clearing "Check Engine" lights (MILs), and making cheap extra gauges.

Going with an ELM USB/bluetooth to OBDII cable and software makes for an even cheaper setup with more capabilities if you already have a laptop to use with it. Even cheaper yet if you have flexible morals and a torrent client.

16 amps aint poo poo, id expect a compressor to draw way more than that. Most cars made today roll with 60 amp fuses on their main power feed junction box.

I = V/R

16 amps at 240v is 3840 watts. At 12 volts you'd need a 320 amp circuit breaker to handle the same amount of power.

bolind posted:

This is why you 'mercuns stress so much when using more than average juice (welders, compressors, espresso machines). Your 120V is fixed, so the amps go up, and there's a limit to how many amps you can draw through normal house wiring. Meanwhile, I have 13 and 16 amp fuses in my little yuppie flat, but since it's in 230V, I can draw the equivalent of 26/32amps had I had half the voltage (120V-ish).

*In not very rigorous mathematical terms. It's still true, though.

It's also why most of us have 240v in our shops, and why we run server racks and other large computing installations on 208v. Most of my blade chassis have a couple of 208V 20A 3-phase lines feeding them. Trying to run them with 120V would be madness and require all manner of additional power cables all over the place.

So when changing the timing belt on a 3.4L 'yota the FSM tells you to remove the hydraulic tensioner, put it in a vice to compress it and pin it in place. Great, except you have to remove the AC compressor and bracket to do that and it's a major pain.

Snap-On to the rescue:



You put that thing between the tensioner pulley and water pump pulley and crank it out. Except I don't have one of those. So I took did something that aparently no one at any of the Toyota forums had thought of as far as I can tell:



The pulley is off of the tensioner, but I left the (soon to be replaced) bracket. You just need to crank the vise clamp as much as you possibly can and use your man hands to get in on there. Then count to 30 as you watch the tensioner retract and stick a 2mm allen wrench in the hole.

Suck it, Snap On.

I used a similar setup to get the crank pulley off of my Honda.

Off wasn't much of a problem on this one, as I already had the bottom armor off and it's a straight shot to the garage floor from the pulley once you're at that point. I just used a breaker bar with a cheater pipe sitting on the floor and bumped the starter as my 1/2" air ratchet was too big to fit (even with the radiator already out).

On is a different story......I don't think there's any way around holding it, and strap wrenches just aren't gonna cut it at those kinds of torque values.

I haven't had any problem with Craftsman sockets themselves but if you go that route budget in a nicer ratchet from somebody else.

The newer Craftsman ratchets are better as far as size, but you're totally right about getting a good ratchet. I picked up a couple of the newer high-tooth-count Snap Ons (I think they are the "Dual 80" series). They were goddamn expensive but worth every penny. They seem to have at least double the detents/clicks whatever, so working in tight spaces is so much easier.

Bottom line: do whatever the gently caress you want to do; it will have no impact whatsoever on your torque wrench. Just don't unscrew it completely.

I'm not saying that I know what's in a torque wrench that might benefit from unloading past a spring, but basic materials science says that springs wear from movement, not remaining in a static position. This very well may be a large component in both the torque wrench as well as gun magazine debates.

Counterpoint: another paragraph that we haven't quoted yet says to move your torque wrench back and forth a bunch of times after it's been sitting for a while to spread the grease out.

My 7" grinder is killing my arms when trying to grind off welds in tight spots.

I've got one. Been using it on and off for a while and it seems fine. It's obviously subject to getting one that catches on fire or blows up, like anything else from HF. Consistency between samples is never so great for them.

So with one that is apparently as good as it gets, it's underpowered (compared to red or blue colored tools) but usable. For $20, I'm not sure one could reasonably expect much more. It gets the job done.
