I saw a $99 sale on a single turbine HVLP spray gun at a Woodworking store
It included the gun, compressor, hose, viscosity cup and a few accessories.
I would want to use it in a middle school wood tech lab to spray "Deft".
Any comments pro or con. Yes I would love to have a 3 stage unit but budget
constraints won't allow it. :-(
Deft makes/made a "brushable" and "spray" version of it's nitrocellulose
lacquer. As you note the brushable version probably does contain retarders
but they would be to slow the cure rather then getting a better flow. Though
a case can be made for the two being the same thing.
In the last several months I've noticed the "spray" version has disappeared
from the local shelves and has been replaced with the brushable version.
Deft being my nitrocellulose lacquer of choice I did some checking. They are
only selling brushable now. They still advertise it as having excellent
spraying qualities, and it is still thinned with lacquer thinner.
All in all a delayed cure can be of benefit since it will allow more time
for any trapped bubbles to escape and more time for self leveling, hopefully
making it even better resistant to orange peel.
As a side note, you are right on the money relating to thinning. Deft
recommends, for better spray results, thinning 20% to 30%. Of course there
is that first little bit, but that's another story.

Several years ago a post said a special proprietary solvent was needed
for thinning for brushing but lacquer thinner could be used if
spraying.

I don't know what was or wasn't posted several years ago but the post would
have made sense then since to make a nitrocellulose lacquer brush you have
to slow the cure which lacquer thinner would not do. It would have had to
have been a proprietary retarder.
Evidently, sometime in the last year, Deft has taken to making only brush
lacquer which can be thinned with lacquer thinner for spraying. A quick read
of the first line of their thinning instructions makes it clear that this is
pretty much due to environmental factors.

I thought "Wagner" and "excellent results" were mutually
exclusive terms! I've got a Wanker up in the attic I'd sell
for $3. Friends and family I know have gotten Wankers and
exiled them to the deepest, darkest recesses of closets,
attics, and sheds, rather than ruin another project.
However, let me state for the record, that I'm too gun shy
to try another Wanker product and so haven't used a Finecoat.
Don't freak out at my comments, Dennis, I'm just messing
with ya! :)

Hi Sam
I switched from convention spraying to turbine powered HVLP several years
ago. Both Harbor Freight and Rockler have <$100.00 units and I believe the
unit you are talking about is going to be similar in that it has a turbine
unit rather then a compressor. A small but not insignificant difference.
In any case I started out by getting a remanufactured Campbell Hausfeldt
unit that ran under $200.00 from the factory. I like the HVLP so I upgraded
to a much more expensive Fuji Q4. A beautiful and quite tool.
My point is that I've used both an inexpensive unit and an expensive one.
I've also followed most of the posts regarding HVLP units in various forums.
So, based on experience with an inexpensive unit, a up town unit, and the
vast majority of the posts I've seen on the subject, any unit that produces
four to five PSI at the nozzle and eighty plus CFM, and apparently even the
inexpensive units do, will give you an "as good as the user is capable of",
finish assuming the proper nozzle/viscosity,.with standard woodworking
stains and finishes. Latex paint may be stretching the point a bit.
What you lose and what may be important to you is ruggedness and longevity.
Taking the compressor alone, they run hot and heat is a killer of any
machine. One has to assume that a very inexpensive unit imported from Asia
is not going to have the quality of parts in it's turbines and long and
continuous use will quickly take it's toll on such things as poor quality
bearings. Going further there is the use of plastic, low grade aluminum, and
non stainless steel parts in the gun. They will require careful attention
and maintenance to keep them in top operating condition. Of course even an
expensive gun should get the same thing but it will give you more wiggle
room if you have a lazy day.
In short, there is a very high possibility that the unit will do the job but
for how long it will is very much up in the air and will depend a great deal
on how it is used and the care it gets.
Deft is my nitrocellulose lacquer of choice, Crytalac my water based lacquer
of choice. With the Deft I go out of my way to get the spray/non brushable
type, however I don't believe the inhibitors in the brushable Deft that is
now so common in the home stores will greatly hinder the spraying process.
At least I hope not since I just know I will be eventually forced into using
it due to it's ready availability over the non brushing type.

I bought a Wagner Finecoat for about $200 several years ago and have
sprayed 8-10 gallons of Hydrocote and thinned latex with it with
excellent results. I recently went to their web site and found
replacement parts available for the whole system.

Sam,
I use a hvlp system in my vintage and antique travel trailer restorations
and love them. It's a great sprayer for solid colors and clears. I do have
doubts about a $100.00 system especially in a school enviroment. You might
watch ebay or your local want ads. We got our unit lightly used for $200.00.
A friend of mine uses this one : http://www.lemmer.com/t55-hvlp-turbine.htm
which was 399.00 last time I looked but is now $423.00 with shipping.
I would keep an eye out for a used system.
Good luck,

I thought Deft was formulated for brushing. Does the label
suggest spraying it? I know they also have aerosol cans of
Deft, but I was under the impression that the brushable
version doesn't spray properly. I know I heard that
"SOMEWHERE", but can't recall. Chances are someone he will
correct me! :) Be aware that it is gonna be highly
combustible so you shouldn't be spraying it without
ventilation and if you use a fan it needs to be an explosion
proof type. Don't blow up the school!

thanks for setting the record straight on Deft, Charlie. I
had a feeling I wasn't totally correct on Deft's
sprayability... <g>

I haven't used the $99 version of an HVLP unit, but the $150 version from
Campbell Hausfeld (perhaps made with the same Chinese/Taiwanese parts, and
in the same factory) works very well for my limited spraying purposes ...
primarily spraying shellac.
You get what you pay for, but if your use is limited to the ocassional spray
job, and once you get your adjustments dialed in, it will certainly do what
the more expensive units will do ... but perhaps with a bit more fuss in the
adjustment stage, which may even be of more educational benefit in the long
run.
