Wondering if my compressor is sufficient to shoot lacquer with anHVLP gun
I picked up a 4 year old Campbell Hausfield 60 gal compressor today for
$325 thinking I could use an HVLP gun to spray lacquer with it. It's 3 hp 220 volt 15 amp. After poking around the net I'm not sure its possible. Sticker says 11.8 SCFM at 40 PSI and 10.3 @ 90 PSI. Max pressure 135 PSI. Anyone know if there's an HVLP gun that will shoot lacquer with a compressor like this..? If so any HVLP gun recommendations..? Thanks -Jim |

use a pressure pot
most any hvlp ,gun will work that way "Jim Hall" wrote in message . ..

You're only going to be delivering between 15-25psi to your gun (I deliver 13 to mine), so you'll be fine. The thing to remember with compressors is that even small compressors will shoot guns, they'll just cycle more frequently. If you tried to use something like a DA, which really sucks up the air supply, you might find yourself on the edge, but even though HVLP wants some delivery capacity, you should be ok. If you were trying to do a big job like an overall on a car, you'd probably find yourself wanting more compressor, but for typical woodworking sprays, I don't believe you'd find yourself lacking. Even large woodworking projects are small compared to the spraying process for autos. As for guns, I shoot a Devilbiss FLG. You can pay a lot more for a gun, but I just don't think you get enough more to justify the cost. The FLG3 can be purchased all over the web today in various kit forms, for ~$120-$150. I turn out paint jobs on cars, some of which had come from shops as renowned as Chip Foose, with an FLG3. Generally, without having to buff the finish out - send it out straight out of the gun. Unless of course... those nasty dust nibs... or the "occasional" oops (runs, sags...). So - for woodworking, and any painting needs most of us here are likely to encounter, a gun like this is all one would need. For most woodworking needs, Harbor Freight sells some pretty good HVLP compressor type guns at cheap prices. They're perfectly fine guns for the purpose at hand. I bought a small gravity feed HVLP for my son to use for woodworking at HF, and I think I only paid $30 or so for it. Works just fine, and he only has a very small tank style compressor. Really meant for nail guns. But then, most small project painting is not all that much more of a load than a nail gun on a roof. -- -Mike- |

I would turn the atomizing air off and set the pot pressure at a few pounds. Then I would regulate the fluid supply needle at the gun so that it would squirt pure fluid in a nice arc (about 3-foot radius) to gravity into a bucket... just a small amount, just enough to see what was coming out. Then I would add the atomizing air to blow apart that stream of fluid and set the fan shape. Simple. repeatable regardless of fluid viscosity variations (within reason of course). The price on small pot-fed units is very low these days and will work with any gun. (I have a gun which once was a gravity fed unit. Now the hose from the pot-feed goes into the top and all works well. I find I also spray rather well when pot-fed. :-} (Not for a few decades now as I can't handle all the Doritos.)

Wow! Very helpful.. Thank you..! Chip Foose.. Overhaulin..?!! I love
that show. That guy has amazing creativity.. as do most everyone else on that show. I like to check out the cars on his website every once in awhile..

Wondering if my compressor is sufficient to shoot lacquer withan HVLP gun
Thank you.. I think I'll try without pots first though and see if that
works.. I just want to be able to spray some future woodworking projects mostly. Nothing big.. I got spoiled using an HVLP gun in a couple cabinet making classes. Hard to go back to the old style after that.. -Jim On 1/6/2010 8:57 PM, Roemax wrote: use a pressure pot most any hvlp ,gun will work that way "Jim wrote in message . ..

Thanks.. I was wondering if you could run fluid supply on top of a
gravity gun. Seems like most of the guns for sale are that style. -Jim On 1/7/2010 7:23 AM, Robatoy wrote: On Jan 7, 9:57 am, "Mike wrote: "Jim wrote in message . ..

You may find a pot fed system funny,however, I have been spraying for over
40 years and tried it all air assisted pot fed HVLP is the simplest and best way to go on the cheap I have a 5 stage turbine accu-spray unit and still use that with a pressure pot. one can produce an amazing finish that way "Jim Hall" wrote in message . ..

Wondering if my compressor is sufficient to shoot lacquer withan HVLP gun
Sorry didn't mean to offend you. I thought Robatoy was talking about
something else.. I appreciate your advise.. I'll look into paint pots. Was just thinking that if I'm only spraying say pint to quart of lacquer on a project and even less sanding sealer with months between projects, paint pots might end up being more maintenance and cleaning than just a gravity fed spray gun. If they allow you to get a better paint job, I'm interested in that of course.. -Jim On 1/7/2010 2:51 PM, Roemax wrote: You may find a pot fed system funny,however, I have been spraying for over 40 years and tried it all air assisted pot fed HVLP is the simplest and best way to go on the cheap I have a 5 stage turbine accu-spray unit and still use that with a pressure pot. one can produce an amazing finish that way "Jim wrote in message . ..

Anyone know if there's an HVLP gun that will shoot lacquer with a compressor like this..? If so any HVLP gun recommendations..? Thanks -Jim It'll blow your HVLP gun Jim. You're only going to be delivering between 15-25psi to your gun (I deliver 13 to mine), so you'll be fine. The thing to remember with compressors is that even small compressors will shoot guns, they'll just cycle more frequently. If you tried to use something like a DA, which really sucks up the air supply, you might find yourself on the edge, but even though HVLP wants some delivery capacity, you should be ok. People always think that a big spray job requires a big compressor, but in reality, it only requires a lot of air. Storage can make up for compressor size, so plumb in some old air tanks or propane tanks for the capacity and nearly no cost. It's only if you require lots air a lot of the time, such as for a sandblaster, that you really need to purchase a large and expensive compressor. If you were trying to do a big job like an overall on a car, you'd probably find yourself wanting more compressor, but for typical woodworking sprays, I don't believe you'd find yourself lacking. Even large woodworking projects are small compared to the spraying process for autos. As for guns, I shoot a Devilbiss FLG. You can pay a lot more for a gun, but I just don't think you get enough more to justify the cost. The FLG3 can be purchased all over the web today in various kit forms, for ~$120-$150. I That's not too bad. I, too, bought one of the cheapie HVLPs from HF. If I ever move from hand-rubbed to sprayed finishes, I'll likely have to buy a real gun. I'll burn that bridge when I come to it. turn out paint jobs on cars, some of which had come from shops as renowned as Chip Foose, with an FLG3. Generally, without having to buff the finish out - send it out straight out of the gun. Unless of course... those nasty dust nibs... or the "occasional" oops (runs, sags...). So - for woodworking, and any painting needs most of us here are likely to encounter, a gun like this is all one would need. For most woodworking needs, Harbor Freight sells some pretty good HVLP compressor type guns at cheap prices. They're perfectly fine guns for the purpose at hand. I bought a small gravity feed HVLP for my son to use for woodworking at HF, and I think I only paid $30 or so for it. Works just fine, and he only has a very small tank style compressor. Really meant for nail guns. But then, most small project painting is not all that much more of a load than a nail gun on a roof. This is true. I've done both (but the only thing I've sprayed is acrylic enamel at the very thick edge of the gun's capacity with warmed paint and 20% Floetrol. Quite the nightmare.) -- We rightly care about the environment. But our neurotic obsession with carbon betrays an inability to distinguish between pollution and the stuff of life itself. --Bret Stephens, WSJ 1/5/10 |
