    Hi

    Tool advice puleeze

    I want a rattle gun to undo crank/clutch/sprocket/rear wheel nuts etc etc.

    Would a cheapy super cheap auto one do the job?

    they have a 2.5hp direct drive black ridge compressor that with hose and rattle gun will cost a little over $200

    the compressor would also be used for pumping up tires and blowing out carbs etc.

    I know belt driven is better than direct drive but I can't justify the extra cost given the infrequent use.

    I've got a SuperCheap cheapie and it works fine.

    Gets used for die-grinding, dremel, tyres, drill, grease gun...

    Its the CFM's that count :deal
    Most rattle guns are designed to run at 90 psi. The compressor needs to be rated to maintain this pressure under flow :huh.
    Unless your just buying it to use once in a blue moon, at home, in which case any bodgy old supa cheapie will do :clap

    I got one of those compressors. Bloody good for what we need it for. I've always thought a rttle gun would be good but there are all the different sized socktes you need as well.

    I have a Hitachi battery rattle gun as I use it for roofing jobs (it's great for tec-screws) as well as on the bike and truck.


    However the compressor jobs are best for in the shed, as there's so many other air tools beyond a rattle gun out there that make life easier.

    My advice would be to look for the most Cubic Feet/Minute it can pump and the largest tank that you can afford with your budget.

    I've got a direct drive cheapy compressor that has been going strong for a few years. When it craps out I'll probably get something nicer but given something nicer costs about 4x as much I'm in no hurry. I wonder how well 2x cheapys in paralell would work :norton

    The great thing about my Repco 1/2" drive socket set is that that the sockets are beefy enough to withstand occasional (ab)use adapted onto my 3/4" impact wrench, but not so flash & expensive that the tool gods strike me down for performing such indecencies on my gear. My 3/8" socket set is a little nicer though so I have proper impact sockets for my 3/8 rattlegun.

    Cheers

    the biggest thing with direct drive el-cheapo's is not to let them run any longer than you have to...
    I have a sort of biggish direct drive cheapo.. it's a fair few years old now... It's viberated the head lose a few times
    but other than that it works fine...

    By the time you get the compressor up to pressure, youdÂ’ve finished the job with a socket set. :evil

    Compressors are good though (even cheap nasty ones). Try to get as big a tank as you can if you want to use for painting etc.

    Id love one but can't really justify it...

    My cheap direct drive one is probably half full of water by now...
    Need to drain it and do some maintenance on all the screw threads sometime...

    Ive used rattle guns for many years with my trade, Just a word of warning with the direct drive el cheapos, Avoid using an extension cord like the plague unless its a heavy duty bugger, those cheapos dont have auto pressure unloaders on them when they restart automaticly, the motor has to spin the compressor up to speed against the pressure in the tank and the combination of the voltage drop in the cord and the higher amp draw for a pressure restart can stall and cook the motor with a standard ex cord. Its happened to me once and Ive heard it happen with a few people. Standard industry air pressure in wksps and in Truck air systems is approx 120 PSI (8.5 Bar). As long as the compressor cuts out at no more than that and restarts at around 90, thats fine. Double hex sockets will work fine as long as you dont stall the gun for an extended period then single hex is better. if you want a bigger tank, go to a compressor shop and get a tank off a stuffed comp or a tank from a truck wrecker and simply connect them together, you can also put the second tank in another location in ya shed to save running long air hoses across the floor.
    Also, squirt a bit of CRC into the air intake of the gun every now and then, it will luv ya for it.

    Put a big tank on a small compressor and it'll take ages to fill up - use high capacity air tools like a die grinder, impact gun or spray gun and it'll never fill up. Volume, you need air flow to make things work. After more than 40 years of using the standard ARO couplings, I'm now in a shop that uses the high flow NITTO fittings - what a difference! I converted 9 airtools over, I never used to use my 3/8 impact as it was a gutless wonder, now it's a little powerhouse. We also use a bigger hose and couplings for the 3/4 gun, it's a brute with that much airflow behind it.

    Lots of valuable info thanks

    I brought the top direct drive super cheap compressor and with a hose, impact wrench, tire inflator and air gun and approx spent $260.

    My shed is run via a long extension cord so I'll replace that with a heavy duty one to minimize the change of a brown out stall.

    I have to change the clutch center on my old klr next weekend so that will be the acid test of the impact wrench.

    Thanks again

    Cheers

    Hey Mark ~ yea, finally ditched the bicycle air pump for a direct drive AC model.

    I just use mine for airing up tires or is that tyres?

    Now, I have to get onto Bart about a trip down:D

    Plus one on the Nitto fittings. Have seen a few workshops converted and now swear by them.

    just some follow-up info for those who are interested

    The $28 rattle gun (along with $20 clutch hub holding tool from t7) wizzed of the klr clutch hub nut without problems.

    The air gun dislodged the crap blocking the idle jet on my old klr after all my previous non air attempts had failed. The air gun also made installing new grips a 30 second as side job (although I learned that you don't leave the throttle grip just sitting on the end of the throttle tube while you blow on the clutch side as you pressurize the bars and fire the throttle grip a looong way - took quite a while to find it....

    I also brought a stanley 1/4" drive air wrench and its great for wizzing in/out 8-10mm nuts and bolts - saves a reasonable amount of time.

    All in all a great success.

    Thanks again for all the advice

    I was thinking today I should get one. Can you get all the allen key attachments too?

    Repco do an allen key set in 3/8th's drive.
    I want a set in 1/4" for the little torque wrench.
