What air tools?
Hi, Ive had a air compressor for years now but only used it for spraying. After a weekend changing my Brembo calipers on my leon where even a
24" breaker bar wouldnt do but an impact gun would, ive decided i really need a set. Can anyone tell me if my wee compressor (50L and 2HP) will
take air tools and any good air guns and hoses that would do for a weekend mechanic?
Cheers

Did an impact gun shift something that a 24" bar couldn't? or is that speculation? My impact gun is running on a similar compressor to
yours and couldn't shift my crank bolt, breaker bar could though. Maxed out it can just manage cylinder head bolts so it's still v useful
and great for quick bolt removal, air saw is awesome too

I've bought most of my air tools at kitcar shows , and I find the `bergen` one's to be pretty tough as well as cheap 
Allso Machine Mart's budget rattle guns seem quite good - I have been trying to break one at work for the last couple of month's without
success !
Its cuz I is blond , innit

your compressor will most likely run everything except an air file ( these need 13 cfm at least! 1/2 inch impact drivers only need 4 or5 cfm ). but as
you have a tank ! you can always give the job a good coat of looking at while the tank refills

I'm a mechanic by trade and started out with the cheap clark stuff from machine mart. I'd be ok for the ocasional use but I found that it
wasn't powerfull enough and soon found that I had to upgrade for something more expensive.
My clarke air gun would do up a wheel nut and stop at around 110nm. Ideal, where as my Mac tools gun I can only wind them in and nip them up
otherwise I'm pretty sure it'd snap the bolt given half a chance.
I'd say go for an air ratchet and a gun if you want to make your work easier and faster, If you just want the power of air tools then
don't bother as it costs to get good quality tools and as a weekend thing its just not worth it.
If you're worried about tight nuts/bolts you may want to invest in a 48" bar, I have one which cost around £25 and I've yet to find
something too tight for it.

i use a 24" bar with 1/2" drive and then just stick a 6ft scaffolding pole over it, i haven't come across anything that has put up a
fight.

A breaker bar is all well and good (yes I do have a snap-on one), but the advantage of an impact wrench is you need no reactive force, that is you
dont have to put something in a vice or lock a wheel solidly to undo a wheelnut. I bought my chicargo pneumatic 'rattle gun' in 1980 - it
cost me 2 weeks wages and has never been defeated and is still going strong.
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

You haven't tried undoing the rear hub nut on a VW type2. I had a 10 ft scaffold pole on one once and couldn't shift it. As already
suggested if your looking to buy air tools get the best you can afford

Regarding impact wrentches. I got a Metabo one from Screwfix (£39 with some bits) and it sorted me out when I was removing the clutch on my GSXR. It
looks nicely made.
As stated previously, really good when you can't lock the thing and can only use the inertia of the assembly to provide the opposing torque (if
you know what I mean, PhD in Physics means I have to talk like that! sorry).
Air ratchets are okay, but they are loud which isn't ideal if you are working in the open air and don't want to offend your neighbours. I
have one but rarely use it for this reason.
Air rivetter is gods own tool. Absolute dream to use (£5 off e-bay for a tucker one in my case). Perfect rivets everytime with no worries of your
Sikaflex going off while you set them.
Tyre inflator also gets my thumbs up, fabulous when doing jobs that you don't want to do (i.e. bike puncture repair).

I've been using my air cut off tool quite a lot lately.
I like the fact its smaller, lighter and more controllable than using a small grinder or similar.
Blow tool is handy and just about the cheapest air tool!
Air drill handy as well for jobs where you can't get in with a normal drill as its a fair bit smaller.
That said if you only really want a rattle gun the 24V leccy one's aren't bad and saves the size/noise/expensive of a compressor.

rusty, r u sure that they wern't opposite thread hub nuts and you were in fact tightening the hub nut instead of releasing it

eBay i just got a bluepoint (almost snapon) half inch rattle gun for £40.
90 degree air drill is useful, i've seen the 90 adapters you can get but there still bulky compared.
My compressors 60l 8cfm, i do run it down quite often, just bought another 50l compressor spares or repairs with no pump, 50l tank, £7

One thing I found out - rattle guns like a BIG diameter air hose to work properly.

I've come across lots of fasteners where a (good) impact gun has won over brute force. Especially useful when dismantling smaller assemblies
off the car where trying to hold it still whilst you apply a scaffold pole would either be impossible or likely to cause damage.

small pcl air line fittings also cause a servere restriction, takes a second or so just to fill an airline i've changed mine to the next size

Will this not undo reall tight stuff? Im thinking of complete suspension/steering overhaul on the Cupra R. The other reason i think i need one is the
tight spaces where a bar is too bulky to get in. It sounds like the tank size may be a little of an issue but i only want to use the gun to undo the
tightest of nuts then il use a ratchet - does this sound like it will fit the bill? Il also make sure i get a thick hose - but whats classed as a
good size?.

Mine hose is 10mm ID,
Forget about those curly bright colour plasticky ones you get thrown in for free sometimes, they add a mega restriction.
Also some air fittings I've had of the same design have had a very different ID.

I've been in the motor trade for 42years , about 6 of them working for a VW main dealer so I will let you answer your own question. I ended up
drill through the castelated nut and splitting it with a sharp chisel

your tools
Hi, I use air tools daily at work good hose fittings are a must and standard air hose .not the thin type .
all compressors operate at around 100psi out put its the size of tank that dictates how long it will run for .
if you plan to build cars for some time i would recommend buying your self air tools of good quality if not don't bother as elec drill breaker
bars ext will be good for one off building .
I find a 90 deg die grinder Avery useful tool i have one from blue point its used daily and lasted me around five years now
cost me around 55 pound ,you can fit cutting disc to it 2in grit and scotch brite pads rotary files ,A good pistol drill as this will be smaller than
your electric drill and therefore allow you to fit into smaller spaces tyre inflator blow gun ,i use 360 connectors Halfords sell them at a fiver each
