HVLP turbine setup

I am looking for input from those of you who are well versed in doing your own finish work. Up to this point I have been doing all of my finish work old school style with a brush and have only recently ventured into the realm of spraying lacquer & poly with an HVLP conversion set up. Unfortunatley I am finding that my air compressor is just too small to support it and my shop space does not allow for me to get a compressor large enough to do so. I've spoken to my brother in law who is a painting contractor and he believes I'd be well served with an HVLP turbine setup. My research seems to indicate that a Fuji or Apollo system may be a good fit for a quality finish job with limited shop space. Any FOG members out there with opinions or experiences with these rigs?
 
I bought a rig at Lowes (Graco?) for $100 or so (just to see if I might want to start using spray more often). It works very well, although it seems to use up the finish more quickly than doing it by hand. There are no drips or dried waves or bubbles. I like it, and when this one dies I think I will buy a better setup, preferably to work with my compressor.
 
I did a lot of research on these units a while back and feel strongly about the neatest Graco 5 stage turbine. It should be the higher end of your budget id imagine but it has the power to spray a wider range of materials. Sherwin Williams should be able to show you one.

Make sure to buy a whip extension as it helps the hot turbine air cool before hitting the finish.

Did you have any luck spraying poly?
 
Only used it for water-based poly and did not have a problem. Also used it with diluted milk paint to do some Adirondack chairs. One thing is that, since tank is on the bottom of the spray gun, I had to make sure that the surface was not fully horizontal, or it would spit when the paint was running low.
 
duburban - that graco looks like a sweet rig and yes it is at the top if not beyond my budget but I can wait if I have to. I was looking at the 4 stagers from Fuji and Appolo in the $800 range but I am open to any quality manufacturer. I wonder if Titan makes an HVLP rig? I am also leaning toward a gravity gun mainly because it just feels more natural to me than a cup gun does. The remote pot option for that graco 5 stage would be the ideal though - no cup at the gun for easiest access to tight spaces.
 
I'm not sure if the graco uses a pressurized pot on the gun or not but that alone will really help with spraying thick bodied material. The photos of the gun make them look pressurized and I do see a gravity styled cup with a pressurized hose going into the top. Sounds perfect.

Haven't seen what the other companies have out now i'd imagine Fuji would be a great buy if they have a 5 stage out now.

I just noticed "Topcoatfinishes" has some video of the unit on youtube. I think he's a user here at FOG and a fellow vermonter. Hopefully he'll weigh in for you.
 
Thaks for the input, it is appreciated. I know 4 stage is considered the minimum for thicker materials and was actually unaware that they had 5 stage units. How much noise do you get from that Graco?
 
WOW - That video is my dream scenario for applying finish  :o  Beats the hell out of my archaic brush method. And the unit is really not very noisy. Not much more than a shop-vac or DC. The real beauty too is that nice compact size of the unit and it is all self contained. Thank you for sharing. BTW - is that you with the rig in the vid?
 
I purchased the Earlex and am very happy with it.
The turbine that comes with it seems more than adequate for the work, and the self storing is pretty nice, too.
 
I'm a fan of fuji.  Their guns are very good.  I've heard good things about earlex as well for an entry level hvlp.

who can point out 3 things this guy is doing wrong in the video?
 
awful technique right? thats mentioned in the comments section.

First i noticed way too much material, and i don't even know what he's spraying. He's also not perpendicular to the surface and seems to spray much more on one half than the other.
 
Having made just about any finishing mistake possible, I'm an expert on how not to do it...  Years later I'm most comfortable with spray equipment, turbine, hvlp, airless, air assisted etc.  I have a great supply of seldon used brushes.  If the guy who made the video p.m's me I'll offer a few suggestions but this amateur woodworker ain't gonna slam anybody elses work in public...

I highly recommend the Homestead Finishing site as a great source of finishing information and products.  Jeff is heavy into the waterborne products but can provide the conventional material also.  His books are excellent. 

Be aware that the slope into quality finishing is just as slippery as the one into Festool woodworking.

YEAH That's a lot of spraying! ;D
 
Hey guys

The video posted above in this thread was shot literally minutes after uncrating the 9.5 about a year ago. Its pretty normal for us to throw some wb clear in, crank the settings and do some dialing.

The machine has been great. I would only recommend a 5 stage, and very much impressed with the 9.5 and the 1050vr from Apollo.

Here is a video shot on site spraying satin impervo last week...

Nothing wrong with a good old brush or even a nice mohair roller for a nice finish. Sometimes beats the heck outta cleaning up after spraying particularly on smaller projects. [big grin]

I am not sure what your current compressor outputs in terms of CFM and what your conversion gun requires but have you checked out Asturo guns. The Asturo ECO SX K1 is rated at 4.5 CFM @40PSI. I don't have one but I had the same problem you had before I upgraded to a better compressor.

I have a Fuji 4 stage with a gravity feed and siphon feed gun and love them and wouldn't hesitate to recommend them and the company which is a delight to work with if you have any problems. While I think turbine systems are not as fast as compressed air systems, I think if you are patient you can get as good or better finish with these systems as you would get with a compressed air system.
The advantage of a turbine system on site, or when you need to change from one coating to another quickly is a real benefit.

I looked at the 5 stage systems and for another .5psi, I didn't think the price was worth it for me, but if budget was not an issue, I have bought the dual turbine with the pressure pot. Unfortunately by the time you pay for the more expensive systems (dual turbine, pressure pot), you might as well just buy a air assisted airless and be done with it.
The biggest asset of a turbine system is the high cfm and low psi which results in low over spray, but this is a drawback when you want to push latex or pigmented lacquer even if you thin with distilled water or Floetrol. In Scott's video, you can see how he is spraying oil based enamel paint and the 5 stage Graco and I can do the same with my 4 stage and pigmented lacquer, and it's as slow (and painful) as you see in the video. The finish comes off nice though.

Whatever system you get, I think it's is a good idea to get a whip hose particularly if you are using water borne finishes. The air that is generated by the turbine is quite warm(even with a whip hose) and most water borne finishes flash off much more quickly because the finish gets heated up as you are spraying and the resulting finish dust lands on the newly sprayed area and creates a lot of fine nibs.

Under the circumstances, (budget etc.) if I was to buy today I would buy an Apollo, Graco or Fuji turbine with the 3M/Accuspray gun with the PPS system instead of screwing around trying retrofit my Fuji guns with the PPS system.

Yes, consider yourself warned, [big grin] this is a slippery slop.

Hope that helps.

Hvlp is slow. The fundamental reason for it is that it takes place at under 10 psi, but with a transfer efficiency of 85-90%.

For what we call "production cabinet grade finish", you have to go to air assisted. Running off a piston pump at 100 times the fluid pressure of hvlp turbines, but still with an hvlp rated gun capable of 85% (and above) transfer efficiency.

In the following video, we are in a cruising altitude of about 1200 psi, spraying latex primer. With that product, you can go as high as 1800 but you have to just about be running.

Downside? Flushing pump and hose. I can break down any hvlp gun into 10 pieces and have it clean and back together in about 12 minutes. With aaa, its going to be at least 30 to flush the pump and hose and then do the gun and tip system.

PS
The operator in the Graco aaa video is Todd (also a fog member), who also appeared in the 9.5 videos in this thread. He sprays perpendicular when its for keeps.  [big grin]
