Air Hose for spray gun

#41
What about a cheaper regulator at the compressor. Can it restrict the cfm as well or are the bigger regulators not as much of an issue?
you need wide open volume up to your regulator at the booth . the very best is a cap regulator for your gun . pressure is restriction . i can run 30 lbs with my small air brush hose but i cant paint a car with it .

you can run a nail gun off a pancake compressor. You can probably use an air brush off of one too, but from the first post of this thread, serjik911 did not say he was having trouble with a paint gun, had bad finishes, he is clearly painting using his 30 foot 1/4 inch hose and wants to know why he is being told he is wrong.
Well, since we are all assuming, you take that same compressor he is using assuming that its good enough to run like he is, and put a bigger hose on it, with the same CFM, and I guarantee, the pressure is going to drop from 30 when he is spraying.
Maybe he is doing one panel at a time, maybe he is painting pedal cars, maybe doors, assuming again. So if you are in a happy place, maybe he does what is "right" goes to his next paint job, and his pressure goes from 30-20 while spraying and starts spitting paint.
That was the assumation, right? Compressor cant keep up, like opening a ball valve when the trigger is pulled, he will start having problems.
So if he cannot afford to be a "real SPI" painter and might have to buy a real compressor so he can use the "proper equipment", the answer alway goes to, if you dont have the right equipment to do it like we say (ego), you should not be doing it.

Us little guys have to stick together. Ego's, LOL, yeah, there are those here.

Dont worry, dont have to reprimand me anymore, or show you are smarter than an idiot, its time to go again, too many ego's here. I will try to stay away this time.

I got rid of all the regulators in the air line going to the booth. The only regulator is at the gun. I threw the cheater one in the trash

This is why we set PSI at the gun with the trigger pulled. The difference is the larger hose will supply a larger volume.

Brother,

I personally like the tips and experiences these guys (including you) post here, as they live and breathe it. And if I can’t afford what they suggest, I will need to find the next best way to do it, but at least I will know where my weak link is. I think there are many ways to perceive what others suggest, it’s all based on your point of view.

One example, respirators....if someone saw me wearing a paper dust mask while painting, and suggests that I should be wearing a better one, but I don’t want to spend the dough on a better one, am I to assume that’s them having a big ego? I wouldn’t think so...they are just trying to help, and I would appreciate it.

I studied this whole psi and cfm issue when building my system last year, and everything Shine, Chris, Texas, and 68 are saying is true. And if I was trying to paint with a hvlp gun using a pancake compressor, I would hope that ALL of you would gang up on me and give me a respectful Ass kickin!

the one thing that makes this site different than all the other paint forums is the fact that there aren't any egos here but there are enough professionals that take pride in this forum and what they do so when someone tries passing off some bs, no matter who it is, they get shut down pretty quick. that is what makes the info on this forum so useful. you really wont come here as a beginner with a question and get bad info. it may not be what you want to hear but it will be the "right way". the compressor/air supply question comes up often here and it is the one thing that is a tough one because painting unfortunately does require alot of air which means expensive equipment. to someone just getting into painting, thats a hard one to swallow and for us professionals we have a real hard time recommending ways to rig something up or half ass anything so feelings get hurt. i do realize the original question was about the air hose which i think has been sufficiently answered in prior posts.

Excellent post Jim.:)

I learned something long ago, that I have kept with me in this work till this day. When I was just a teen, I got a summer job the year my folks moved here to Virginia. I had always loved cars but never opportunity to work on them. My father did some of this work but had no passion for it and at that time other things held his interest. So the man I got the job with was a unique, one of a kind type of guy. Good person but he was a "schemer". Always trying to think of ways to get rich quick. The process did not interest him only the end result.
When I started helping him he had just gotten his Dealer's License and was starting to sell cars and buy and repair Insurance Salvage. He was the biggest half ass I had ever met. Literally. He attempted to cut corners on everything. From the "shop" that he worked out of, to the way he repaired the cars. Example he was buying Ford Fiesta's and later Festiva's and getting another rebuilder to rough pull the damage on their frame machine. If it was a front hit he would almost never replace anything under the hood, he even got famous (more like notorious) around here for using 2x4's in place of the bumper reinforcement on those cars and others. I'm not making that up. If a little filler was good, more was better. Actually working with him and using body filler really helped me as I became very good at applying and shaping body filler and getting it straight. This all caught up to him quickly and he developed a reputation as someone to avoid buying a car from. He initially had a lot of sucess and had he done things even somewhat correctly he would have been succesfull enough to make a nice living from repairing and selling cars. He never did. I watched him struggle to eek out a living, going deeper and deeper in debt. I stayed friends with him but left after I turned 18. So many times I would tell him just do this the right way, he would complain about how much it would cost, but in the long run it cost him more by being so half ased about it. Working with him motivated me to want to do things right. To be as good as I could be. I haven't achieved what I would like yet but I'm still trying.

I guess the point is if you are always looking for shortcuts, ways to just get by, you are never really going to do anything that amounts to any significance. And probably you will work harder trying to shortcut things than if you simply tried to do things the correct accepted way. I know that's how my friend Glenn did. Struggled to survive until the day he died. RIP Glenn.

Another example, he wanted to have a rollback for the business. So we went to the salvage sales and finally found something really cheap. A Ford F700 that had an engine fire. Gas motor, underpowered. He then proceeded to scour the scrap metal yards looking for suitable metal to make the Rollback. It was actually a 4 car carrier. Glenn was jackleg smart. He could do all this in his head and eventually make it work. Which he did. Took him over a year though. Whole thing got welded together with a 220V Lincoln "Buzzbox" stick welder. That welder did not have the power to make hot enough welds on the thick c channel he used for the framing. The welds were constantly cracking, when they did, he would just weld over the weld.o_O I was too young to know how dangerous this was. I can remember being in traffic on I-95 in Richmond, 17 years old, me driving with 4 cars on this beast, doing 65 mph. We did some things that looking back on it that were so irresponsible, I thank God that he or myself didn't kill anyone.
So he spent a year and more money and time than it would have cost to get a standard Ford F450 rollback. All that time making it could have gone into fixing cars and selling them. And when he got done with it, it was still relatively worthless.

The professional painters with egos would not be on this forum, because they already know everything. I come on here to learn, even though I've been doing this everyday for almost 40 years. I also come on here to help people with questions I may know the answer to. If I'm not sure, I don't answer, but read others responses that may have more experience or a better solution than I may have. There are lots of painters out there that never try to improve, only get by. They never get any better, but are convinced their way is the only way. Most of what I learned when I started was trial and error. Never really had an exceptional painter to learn from, and for sure didn't have the wealth of knowledge and quality information available on this forum. My understanding was the OP asked a question because he wanted to learn, not because he was told he was doing something wrong.

I first got interested in automotive refinishing back in the lat 60's. In those days you had the option of laguer or acrylic enamal. When the technology really began to take off and the urethane hardeners started to show up it really fascinated me. The first I used was Sherwin William's Polisol. It worked great for the time and the first car I painted with it lasted until about 4 years ago. 45 years isn't bad.

The point is it always has amazed me, how many old guys in the business were absolutely unwilling to learn. They thought what worked with one product 20 years ago should still work today, even with all the inovation the industry has witnessed. Those same guys will be the ones who swear they got ahold of bad paint when the job fails.

Most forums have a certain number who will answer questions or offer advice to feed their own egos and frequently don't know what they are talking about. While it does happen, we have very little of that here.

This forum, as well as Barry, has really been a lot of fun for me. I have really enjoyed the input from those who have more experience than I do and I have enjoyed contributing when I felt qualified to do so. The technoligy has come so far I continue to be amazed. Just think what we would probably have to work with if the government would keep it's hands off of it.

On the other hand, just think how many of those old guys would be dying off now who said they didn't needed a respirator.:(

Well, there is my unprovoked ramble for the day........:)

So, back to hose. today i got my 3/8 flexzila pro hose and high flow connectors. connected everything and first thing i noticed: i got my 29 psi at the gun with less noise than usual. usually 2 bar noise for me is pretty loud, almost uncomfortable, and by noise i always wanted to stay at 20psi. but today i hooked the gun, adjusted the gun by comfy noise, looked at the gauge and surprisingly it was exactly 2 bar. maybe im wrong, not sure.

Us little guys have to stick together. Ego's, LOL, yeah, there are those here.

im a little guy. havent pulled the trigger much over the last few years but there was 5-6 years i had some type of repair/ painting in my garage quite often.
this little guy prefers to listen to what the big guys say. their suggestions are given quite often from their own mistakes that they learned from and from the ones that went before them. plus, the combined experience of the major contributors here = prolly 10 times my age. do i go with what i think or what they know? that depends on what i want the outcome to be. i want pretty dam good so goin with what they know seems to have worked pretty dam good for me. these are my last 3 repaints with the p/u being the last one about 7 years ago. followed the advise i read here and had 3 happy customers. dont know where the 'stang is today but i talk to the he p/u and pacer owners. they are still lovin their rides and the paint jobs.
i just did the work. reading the advise in many threads here gave me the knowledge of how to do it without having to redo it.
now, when i go to paint a vehicle with a couple cases of rustoleums finest spray bombs, ill look ya up for advise.;)

The flexilla 1/2" hose and the devilbiss hiflo fittings is what I use. Cant beat the price of that 50ft hose on amazon. Although after about 8 years, my one fitting is starting to stick alittle when I disconnect it from the gun.

Off Topic, the one thing I enjoy about this site is that there are more knowledgeable pros than there is "garage hacks" like myself. So there is VERY LITTLE misinformation floating around. You don't need to have thick skin around here, you just have to be able to accept the truth and move on.

First car i ever painted was with a 30 gallon oil-less compressor, small hose and cheap gun, it got the job done but what an incredible struggle, shocked the compressor didnt start on fire!

I started out to restore the car in my Avatar. Progress got interrupted when a guy offered to pay me to do his car. That started a chain reaction that still hasn't let up. Below are a few but not all. Photobucket's extortion effort cost me some pictures of projects that I neglected to download in time.

I came to SPI a long time ago when looking for an Epoxy Primer to replace the outrageously priced PPG I was using. This forum has been a great help to me and the pros on here are always willing to break technical things down to a level where a beginner can understand them.

I have folders with copied and pasted gun setting advice, body work advice, welding advice and one for spray guns and tools . Much of which came for this site. And of course Barry's "Perfect Paint Job" was the first download.

What you say here in this post is why I have settled here and will use SPI products. You and the rest of the gang on this forum immediately stood out to me from the other forums i scanned when I started looking for help. I spend hours each night reading what all of you have posted, and this knowledge is top notch. As we all know, the "doing" part is where you really learn and earn your stars, but being armed with all the info you guys generously provide sure helps out with the learning curve. I thank all of you.
