    you can hire a small compressor it will take about 20 to 30 mins to fill up and will just about undo 1 wheel with a air gun by the end it will be well down on power till it fill's up agian ,garage's use's 1 or 2 very large compresser's running 150psi and are very noisey like the road works ones but indoors

    So electric tools are probably a more viable option?

    Rich,
    If it's an impact wrench you are thinking of, Snap On do a biliding battery impact wrench...mine is the 1/2" drive version and it has mammoth torque. Does everything I ever need it for. Re-charges in about 15mins too...
    Not cheap though...but quality.

    Cheers, will look into it! looking for impact wrench and cutting tools also... The price of the tools is excellent, however, the price (and size) of the compressor makes it a bit more expensive!

    Well, unfortunately, it doesnt look like the new car can happen cos of b*stard insurance [img]/ubbthreads/images/graemlins/cry.gif[/img] So this is mods to the existing one...Thats unless an insurance company does a 180 and decideds to give me a "Happy Birthday' have a cheap insurance quote!"...Unlikely.

    So... the jabba conversion is back on the cards and will happen as soon as possible. So im getting other mods out the way in advance. This one should be pretty sweet, and we will be producing it as a kit for the A3 and Golf when i have perfected it!...not saying what yet tho!

    Re: Air compressor

    If your after a compressor have a look at the screwfix website..

    http://www.screwfix.com/app/sfd/cat/...5&ts=04563

    I have this particular one and it seems to do the job nice.. Makes life a lot easier..

    It not a great big heavy duty one.. But for un-doing wheel nuts, suspension bolts it's ok..
    I have used it with my spring compressor and it worked ok with that too.. it does run out of air sometimes, if you use it too much too quickly but after a minute or so your off again once presssure has built up again..

    What about for cutting tools? i guess they require less air!?

    Re: Air compressor


    To be honest i've never used any cutting tools on this compressor..

    I would guess they do use let air, but need a constant supply of air at the same pressure when using it for a long time. I don't think this smaller unit would be able to keep the pressure constant for a prelonged period. You would prob have to stop let the pressure build then start cutting again.

    Also depends what cutting tool you use..

    Hope this helps..

    Re: Air compressor

    Best all round compressor is a 3hp belt drive with a 100L tank this will run all air tools well with a fad of about 9CFM especially useful for spraying, impact wrenches-for taking wheels off-die grinders-cylinder head mods etc. Try these guys this is where I got mine from. powertools.co.uk

    Re: Air compressor

    How much is the SnapOn cordless impact wrench, no list price on UK site (no stock either), USA site has list at $470 (approx). You were right when you said they aren't cheap.

    Check out

    Just Off Base Tools - Excellent place for tools!

    Not Snap-on but they always supply good quality stuff!

    or
    Screwfix - Also Very good!

    DeWalt are the industry/top end stuff from Black & Decker... I'd probably get this one!

    its difficult to find the Snap-On ones in the UK

    Re: Air compressor

    Screwfix are not bad but you can find the Dewalt cheaper

    http://www.comdir.co.uk/frameset.asp...ntGroupID=2052

    Free delivery and free tool case.

    The Dewalt doesn't look up to the job it is an impact driver not an impact wrench, Dewalt make an impact wrench with 18v battery 300 ft/lbs of torque with a 1/2" square fitting.

    BTW in the USA the Dewalt Impact Wrench can be bought for <$300. Not sure if it is available in the UK but at the current $/ rate it's probably worth importing one and buying a UK Dewalt charger.

    I got mine from my local Snap On dealer who I've used many times (just like the local Mac dealer, Sykes Pickavant dealer, Britool dealer, Halfords store etc...).
    I think I paid 300 ish on special offer.

    I cannot recommend it enough...I've used the cheaper versions and they just don't cut it...they either don't have the torque, don't last, or take too long to charge up.
    The Snap On stuff is quality...I guess it's true that you get what you pay for.

    You should use a proper set of impact sockets too...but I don't always...my 1/2" drive Britool stuff is holding up just fine!

    Re: Air compressor

    As for other tools:

    I use a 5" (I think it's 5") electric Angle Grinder and have no problems.

    I also use a Draper Die-Grinder - it's good because it has adjustable speed - I prefer it over my old Makita Die Grinder as the Makita wasn't speed adjustable and for re-working cylinder heads and manifolds etc you need to be able to regulate the speed. Metal cutting bits are find at high speed but the little Scotchbrite bits used for getting the cross-hatched satin finish on the inside of cylinder head ports / inlet maniolds require low speed for operation.

    If you want to use air grinders (angle or die) you'll need a BIG compressor as they are very air hungry - believe me! I sometimes run low on torque at work on a fully industrial set up!


    BTW, if it's headwork / manifold work you are thinking of...patience is the most important thing to remember. I have put about 200 hours into re-working and polishing the TB, inlet manifold, head, exhaust manifold of my Mk3 GTI. It all pays off when you get it built and mapped and it's kicking out 196BHP / 159 lb-ft!!

    Re: Air compressor

    Cheers for the advice Glen!

    Tools are for fabricating mainly... I think i'll leave the impact wrench for the time being...not really a necessity, but would be handy. Will get myself a decent angle grinder, and a work bench cut-off tool... Me playing with cylinder heads and inlet manifolds .etc is a fair way off for the time being i think, however would be interesting to play about in the future.

    Cheers

    Re: Air compressor

    I tried it out on the M8s Safira which recently had the KwicFit treatment (wheel key + 3ft bar to crack the studs) and it worked a treat. It will do for sitting in the boot just incase.
    I told the missus about it and she said the only tool she'll be using if she gets a puncture is her mobile phone [img]/ubbthreads/images/graemlins/lol.gif[/img]
