Air Compressors

The math may be against you champ...

Point is, 2.5hp may not actually give you over 200lpm.

3hp, on the other hand, is already well over 200lpm...closer to 275lpm. With those 15amp units, you could be expected to run a die grinder for a while without issue, too.
 
die grinder you lost me. lol

that sucks then mmm wish i new how to paint and just buy a compressor for our own shed then i could have 15amp grrrr
 
hmm I see, are we saying that I straight out cant spray without more air or that Ill just have to wait for it to refill?

Also, how does the quality of the water trap affect the paintwork? Should I aim for anything in particular?
 
Honestly, if you don't know this stuff...leave it to a professional.

If you can't afford to set up as well as you need, then expect less-than-professional results.

Not trying to be mean, but I spent about $2k on my set-up and that was with a new gun and second-hand compressor....it gives results that are acceptable, but nothing like a professional set up.

(you would need a 15amp circuit, obviously with 3hp)

Or a 10A socket and a semi hill billy nature ;)

But yer, with anything a bit less than 3hp, you will get to spray as you normally would for a small amount of time (As the LPM from the gun is only determined by the pressure and tank capacity and hose diameter etc) BUT the LPM of the compressor will be less than that, and so after a while your tank will be low and you will have to stop spraying and let the tank build up pressure again.

Technically, its possible to run a spray gun of a 12V car compressor from bunnings for pumping up bike tires. If you hooked it up to a 100L tank and turned it on for ages and let it build up 110PSI, you could spray with that. But then your wait between tank discharges would be measured in hours/days not minutes.
 
What about like petrol 2 stroke motors hooked up to the pump..? I don't know if petrol compressors or norm, but I know I used one when working with my uncle out in the middle of the paddock.
 
So outta of his price range,

Would it be possible to make a ghetto style one? by buying/finding a compressor with a broken electric motor (obv belt driven) and then welding (or however) a motor onto the tank?

Yes, you could even make it electric if you are that keen about ghetto style compressors. Find a washing machine/ dryer in council pickup and bolt it to a old compressor unit. Cheap but nasty. We have provided lots of solutions. It's really up to you which one you want to take.

Sorry tryg but I don't think information regarding the minimum air pressure I could get away with is the kind of knowledge I can pull out of thin air. I've seen good results come out of fairly pissy compressors, however I've always wondered whether having a lack of air pressure would cause the paint to not adhere quite right?

im still 50/50 on painting myself. But I'll need to put some spray putty/primer down myself at the very least to get it to a condition where its paintable and have everything smoothed over. I have a mate who was a panelbeater before he retired who'll be guiding me through it, but I just don't like to bother him too much.

also If done by me I don't expect professional results, but I do expect something that looks half decent lol....one panel at a time and if I can't get it right then I'll go pro.

(this is all in reference to me buying something old and fixing it up btw :), hq statesman may be mine on thursday!)
 
awesome you are getting a HQ statesman! styleside?

and as for tyrg. i have previously stated i will not be the one doing the painting all i will be doing is all the prep work.

i am looking at buy the compressor for my painter. my used to be a professional painter paintinf airplanes, normal cars and $15000 custum paint jobs. he is now retired and only does work us. and it is free which i like :)

he was previously using dads old compressor was like 25yrs old 10amp, 100litre tank and a belt driven motor dont know about HP sorry. But now as dads compressor has died he requires one to paint my car again. and i dont expect perfect jobs i expect a job that will look alright but not great. as it was already sold when i crashed it. and i am now just fixing it up and giving it to the lady for $5500 :( because i need the money to pay dad back for the fines i got from court for "undue care" my insurance and the repair costs of my car.
 
Well, as for all the rhetoric, just buy a $200 compressor...that is the answer you seem to want and for us to adopt... I am telling you, as a guy who also paints quite a bit, that I have found you can paint small items well with those cheaper units, but big items like cars, you need continuous air for a decent job. They paint cars 'continuously', so that the paint lays together...

I am sorry, I paint bikes and I don't accept a rubbish finish... I don't think $2k is a lot to set yourself up for a lifetime (because my gear has lasted 13 years and is still trouble-free).

It matters not who does the job, if the tools wont allow them to do a pristine job, you will just get a 'good' job for the tools that you provide. Imagine a carpenter with a handsaw and one with an 'industry-level' compound mitre saw... the best job is done by the tradesman with the skill and the tools to back him up...

I really don't care if you need to only buy a cheap one.. you asked the questions, those were my answers....

If you would like people to just say "f#ck yeah, that POS $200 compressor is the shiz", then just tell us that in the opening paragraph...

sorry tryg i was just thinking that you were thinking i would paint it myself. and thanks for all the advice i will try and put as much money as i can towards a compressor. but seeing as i am a poor uni student with a rubbish job. and a broken car and now an insurance bill fine and a repair cost to deal with i can not spare to much. thanks for your adice everone
 
Or.. just wait until you can find someone (who has the equipment) and you can do it without setting up your own...

I know that my first painting foray was done at someone else's place, meaning I only paid for the materials and some cartons of beer for his time/equipment...

that's not what I wanted tryg, I just wanted an idea on everything and mainly if I'd 'get away' with it. Or if I could put just a little more into it considering I've got the extra tank available and get by. meh whatever, I'll have a look around and see what I end up with come painting/rust removal time. You going on about your '2k' setup doesn't help.

If im going to outright end up with a *poo* job then I'll obviously look into a much larger compressor. and the sca compressor was just an example, I don't plan on getting that one. I do recall total tools having some reasonably priced models around the 500 mark which from memory put out around 9-10 cfm. They were massive though and I don't think I really have room for one.

edit: Had a think about it, logically I'd be able to get away with a smaller compressor just laying down whatever primer/putty I'd need to after fixing up rust etc wouldn't I? since they'll be small areas and I'll have the tank capacity. After which I'll have someone paint it? hmmm that could work.

I thought I had this arrangement....but the guys wife doesn't want him painting for himself anymore so I don't think he'll be up for painting mine lol

styleside? I will be getting it provided all checks out. Took a look at it yesterday, and I'm really happy with it. Alot of surface rust but only rusted through in a couple of places, getting someone who knows more and is more familiar with these cars than I am to take a look for me come thursday then it will be mine :).
 
Couldn't be bothered to read everything i have missed, but success for a amateur spray painter is achieved by have a compressor with a Min specs of 2hp (belt driven preferred)/60L tank/8cfm and make sure you have a regulator on the hose even if the tank has one. A small one near the can can be good, as long as its small and light weight. I always have a small spare compressor around just to get out of trouble if the main one fails.
 
thanks guys very good information

KNK if you want to have a look at my crash thread that is style side.

and if you need to know any information about the old Q's between my dad and myself we are getting to know a fair bit about them with dad owing heaps in his day and this being my second one and also second time we have done this one up lol
