I have a small workshop and use a 3 gallon compressor which delivers 3.0 SCFM and 40 PSI and 2.0 SCFM at 90 PSI. I would like to begin spray finishing with water-based finishes and wondered if anyone knows of or has experience with a conversion gun (HVLP or LVLP) that would work with a compressor this small. The pieces I will be finishing would be cases, shelving, small mouldings etc. Nothing huge.
Thanks for any information!

Here is a link to spray gun world's website and a page devoted to the subject of small compressors. There is a ton of info on this site if you click around for awhile. They also have excellent prices and good customer service. I believe they will offer you advice on the phone also if you call them. You wont find any $30 guns here, but they sell quality stuff at good prices.

T,
I would agree with Rob that spray gun world has a huge selection and great prices.
I would disagree that they have good customer service - in fact I would rate it as second only to the incredibly poor service one would receive from Laguna tools. I run a cabinet shop and tried for 2 weeks to contact "mr spray gun" or whatever the hell his name is to ask some questions to determine the best gun for my needs. I was trying to spend $500-$600 with his company and could not get a response to emails or phone calls. Be advised I think there are only 2 employees that work there - a phone answering girl who know absolutely nothing about spraying and the guy who know a butt load but won't pick up his extension or call you back. And on top of that the order that I finally placed did not show up in 2 weeks so I called and the girl who doesn't know spraying told me oops it hadn't shipped yet but I would have it in 5 days. Yeah, thanks bitch.
I would browse their site and buy from someone else when you decide what you want.
There, now I feel better. No offense, Rob.

None taken Lee.
I am sorry to hear that you had problems with them, but I am glad you posted. That's the point of this forum, maybe I got lucky, maybe you got unlucky. Either way it helps others to hear all opinions.

Call Jeff Jewitt at Homestead finising. I did and he walked me though with a lot of questions and sold me a unit that works fine for me and my compressor. I also bought his finishing book sold by Taunton.

PS I am a hobbyist, so no expert, but he helped me. Good luck.
If it moves, tax it. If it keeps moving, regulate it.
And if it stops moving, subsidize it.
Thanks for your suggestion! Can I ask you which gun Jeff recommended for you, the size of compressor you have and what sort of finishing you do (type of finishes, size of projects)?
Sure, I'll have to get those details this evening. My application is mainly water based dye & Shellac. Government's view of the economy could be summed up in a few short phrases: If it moves, tax it. If it keeps moving, regulate it. And if it stops moving, subsidize it.
I have a devilbiss gti for spraying cars and anything you can imagine. It sounds like you haven't been cursed by the "generation lock" of growing up with high pressure guns(binks #7) and having to make the conversion in mid-life. Thats good.
The EPA has driven the crowd voluntarily and .. otherwise to the HVLP. So be it. You can get great results from low pressure but -- be mindful its a learning curve that you have to practice and get comfortable with BEFORE you spray your precious piece of whatever. You will cry if you ignore this caution. Practice on some scrap surfaces. Go to a window replacement business and get a bunch of single pane sliding doors to practice painting. They have tons of them. This is a smooth surface that you can practice avoiding things like "orange peel" and shading lines. Practice.
The Gun: its all in the pressure and the tips. 1.3/1.4/1.5
Having said that, it sounds like you have a small compressor and this makes it a challenge(very difficult actually) to get killer results. Even with HVLP, you need lots of continuous air pressure and don't let anybody fool you. It matters.
Last piece of advice from a guy who has botched a job: get a peanut pressure gage on the handle of the gun you buy. Look at is and understand what that is. Additionally, put a filter on the plug in point of the hose to gun. Its cheap and it will save you gallons of tears.
good luck
Thanks for your suggestions. Great idea aout practicing on old glass doors. I expect they would show mistakes well.You mention knowing about the pressure gage at the gun inlet. Can you elaborate on how to use that?Thanks!Also, can anyone tell me if I get a gun that requires low cfm and later get a compressor that delivers greater cfm's, can I still use that gun with the new compressor. Do you have to match the gun and the compressor?

I am talking about "peanut gages with an adjustment dial" for the gun. Photo attached for clarity.
My friend -- you can not have too much stored air pressure. The larger the tank the steadier the whole work process will go. Go to the bank on that.
In the photo you will see the gage and the dial(below it is an inlet water filter). I put an old high pressure gun next to the hvlp gun to see the size difference. Some are smaller and this could be important getting in small cabinet areas.
Again, I would emphasize the TIPS for the gun. A 1.5 does not work well for all viscosities. If you want to shoot low pressure you will be needing different tips for different materials. Also, the part all demonstrator seem to leave out of the presentation: temperature. Its a biggy.
Play around for a few hours. Get confident with the equipment- it takes time. This is one of those things that will make you cry when you screw up.
Best of Luck

TB:
In light of Lee's poor experience with Spraygun world, you might want to check out TP Tools. I got my gun there and they were very helpful.
