Setting up and spraying with an HVLP gun

Setting up and spraying with the Harbor

Freight HVLP gun #38308 and the 43430

Pressure Adjustment: Open your compressor regulator up so there is plenty of air pressure in the line to the gun (I set mine to about 90 psi). Next set the regulator on the gun handle to 50 psi (what I use for DP40 and K36) with the trigger pulled and leave it set there. Close the valve at the bottom of the handle (on the gun, not the regulator) and then with the trigger pulled, open it to the point where the air volume starts to stay the same (just listen to it) and leave it there (it should be pretty far open at this point). I never mess with this after this unless I think it has been changed.

Note: On my two year old gun they say the maximum pressure is 60 psi. On my new gun it says 40 psi. Instead of the 50 psi above you might try 40 psi if your gun says 40 psi max.

Fan Adjustment: Next open the fluid volume control about 3 turns for starters (at the back of the gun). Close the fan control down (on the left side of the gun behind the nozzle) so when you spray you only get small round circle. With the gun about 6 to 8 inches from a test surface (I use the garage door or better yet some sheet rock, or masking paper) move the gun across the surface (about 6 to 8 inches from the surface) and pull the trigger. As you are moving turn the fan control until you get the desired fan shape/width (about 5-6 inches wide top to bottom oval shape for overall painting) (remember if you are spraying up and down on a surface you can change the nozzle at the front of the gun 90 deg. so the fan is horizontal).

Fluid Control: Next after getting the fan the right size continue spraying and adjust the fluid volume at the back of the gun for the final adjustment to get the fluid right for the gun speed (how fast you sweep it across the work). You want to be laying on the paint at a pretty good volume, but not causing runs at a normal gun sweep speed.

Changing the pressure to match spec sheets: Now you’re ready to paint and with 50 psi at the handle the gun is spraying about 10 psi at the cap. If you want 5 psi at the cap put 25 at the handle regulator (8 psi = 40 psi, 7 psi= 35 psi, etc.). You can’t actually see the pressure at the cap which is what the spec sheets are referring to. The gun is internally regulating the pressure down based on the inlet pressure. Some expensive guns have a gauge off the back of the handle that tells you the cap pressure and then they also have a regulator and gauge at the bottom of the handle like this gun that regulates the pressure into the gun.

Painting: Look at what your painting and the way the paint is going on the surface right behind the gun and adjust from there. For instance if you want to spray some small areas/parts you can turn the fan down to a small round size. You will also have to greatly shut the fluid volume down at the back of the gun (clockwise) at the same time to avoid runs. I usually turn the air pressure at the regulator on the handle down to around 25 to 35 psi to do spot work like this.

Proper Pressure: Remember you need a high air pressure (Set as the spec sheet calls for) so that you get proper atomization and so you can turn the volume up. The higher pressure will actually mean fewer runs since the atomization is better. This is not so critical with the primers, but you really need it with the sealer, base, and clear coats so you get good coverage without runs and with little orange peel.

How should I properly set up my HVLP spray gun?

How should I properly set up my HVLP spray gun? [by: MARTINSR]
Hotrodders Bulletin Board: Knowledge Base: Body-Exterior: Articles

Being HVLP (High Volume Low Pressure) and low VOC (Volatile Organic Compound) products are the way the industry’s going, I will be referring to them in this discussion on painting and paint guns. Most all basic issues dealing with HVLP can be applied to conventional guns, atomization is atomization. The HVLP just arrives at it differently.

The object of the spray gun is to break up the primer/sealer/paint/clear (I will call this “PSPC” from here out) into small particles and lay them in neat little rows on the panel being PSPR’ed. So, the whole outcome rests on how well the gun is doing this. Picture the droplets of PSPC coming out of the fluid tip of the gun and then the air “slapping” them into smaller droplets.

You have two things that help you with this process: air and solvent. Solvent can mean something that is already in the PSPR from the manufacturer or something the manufacturer has told you to add to it. By the way, you should always mix in proper ratios as instructed in the tech sheet. The thinner (less viscosity) you get the PSPR or the more air you have at the fluid tip of the gun the more it will break up the PSPR. The target for you is getting the perfect balance needed. Too much solvent and the PSPR will have no body, fill, durability, etc. Too much air and you blow the PSPR everywhere but the car, and you’ll have poor adhesion, excessive texture, etc.

So, the answer is proper air supply and gun (and fluid tip) choice, and how you adjust it.

With today’s high-solids low-VOC (Volatile Organic Compound, you know the bad stuff that goes up into the air we breathe) products, there is less solvent. And with HVLP guns there is less air at the cap to break up the PSPC. Proper air supply and gun setup is more important than ever.

FIRST THINGS FIRST — your compressor and air supply.

An HVLP gun requires more VOLUME of air to operate (the V in HVLP, High Volume Low Pressure). Now you may notice that your HVLP gun is adjusted at maybe the same PSI as an old conventional gun, around 50 lbs at the gun (many HVLP guns are set at much lower though) so where is the “Low” in PSI they are talking about? It is at the actual air cap where the air and paint come out. An HVLP gun has only 10 lbs at the cap while a conventional has upwards of 50! So the VOLUME of air (CFM — Cubic Feet per Minute) is the key to proper atomization with an HVLP.

If you have a gun that requires 15 CFM you will need a compressor and plumbing that will produce that at a very minimum. There are HVLP guns that need as little as 7.5 CFM so you can get good results even from a smaller compressor. Air supply is a complete subject by itself, so let’s assume that you have the air supply needed and move on to gun setup.

So atomization is the key, but why? Why can’t you just lay it out wet and let it “flow”, as an old painter will say. Picture a jar full of bb’s; they will represent small, atomized droplets of PSPC. The gaps in between the bb’s is solvent. Now picture a jar filled with marbles, they will represent large, poorly atomized droplets of PSPC. The gaps in between are, you guessed it, solvent.

If you apply your PSPC in large poorly atomized droplets, what you will have is a film full of solvent. This can and will cause slow curing, shrinkage and dieback (the loss of gloss in the hours and days after application).

So, now that we have learned the need for gun setup, how do we do it? Let’s start with the fluid tip choice. The newer high-solids low-VOC PSPC products need to be broken up more, so a smaller fluid tip is needed.

Basically you want the smallest fluid tip that will still allow you to PSPC the particular part you are PSPC’ing, keeping the entire thing wet and in a fair amount of time. In other words, a 1.0 tip would be beautiful for clearing one fender, but would be lousy to paint a complete. The application would be way too slow, and the first panel would be way too flashed by the time you got back around to it. So you need to compromise — a 1.3 is a great all-around tip, while a 1.5, though getting a little big, can get you by. If you read the tech sheet on the particular product you are shooting, it will have a recommendation for fluid tip size.

There are needs for other tips. For instance, when shooting polyester primer you may need as big as a 2.3, but for urethanes and epoxies, the 1.3 or 1.4 will work great. If you plan on using a pressure pot or painting a bus, all bets are off and we would need to study a little bit more.

As an example of the use of a 1.3 tip, I did a test once that proved the point well. I shot two panels of metal with a medium solids urethane primer. One was shot with a 1.3 super high atomizing top of the line topcoat gun. The other was shot with a 1.5 (or a 1.7 I can’t remember) “hoser” primer gun. Three coats were applied and after a full cure (the one shot with the larger gun took MUCH longer to flash and cure by the way) the film thickness was measured. The one shot with the 1.3 tip was 2 tenths of a mil thicker! The larger gun laid out the marble sized droplets full of solvent, and when the solvent flashed the film shrank.

You need to “tune” your gun EVERY TIME you use it, just as you would tune a guitar before you perform. This is done with a very basic sprayout pattern test. This very basic test tells you how your gun is atomizing and you adjust it to achieve the best atomization you can.

Let’s do a spray pattern test:

Set the fan width as needed (you don’t want to change it after you have “tuned” the gun). Turn out the material knob about 2 1�2 turns. This is the “mixture” adjustment, kind of like the idle screw on a carburetor. The farther in it is screwed the lower the fluid to air ratio is and the smaller the droplets will be. The farther out it is, the higher the fluid to air ratio is and the larger the droplets.

Set the air pressure at the inlet to the gun to the manufacturer’s specs. On an HVLP gun, this spec is usually found on the gun, and is the maximum PSI it can have while still maintaining the maximum 10 lb at the cap for legal HVLP transfer efficiency (68 %). You are now ready to do a test sprayout.

Tape a piece of masking paper on the wall for the test. Hold the gun at a right angle to the wall, just as if you were going to paint the wall. Hold the gun at a spread out hands distance (about 8 inches, or 22 centimeters). Pull the trigger to completely open for a split second and then close it. You want an ON-OFF wide open-completely closed in ONE movement. You should have a cigar shaped pattern with complete coverage in the center with fading coverage going away from the full coverage cigar shape in the center. The center should be fully covered without any runs. If you have runs, either you are holding the trigger too long, you are too close, or the gun is simply applying too much material; in which case you need to screw in the material knob or turn the air pressure down. But most likely if you have turned the material knob out the 2 1�2 turns and the air is set at the factory specs, you are just too close or holding the trigger open too long.

The droplets you see trailing off the center are what you will use to “tune” your gun.

Turn in the material knob to make the droplets smaller (and or raise the air pressure). The balance you need to attain is the smallest droplet size possible before you lose the coverage desired. In other words, if you turn in the material knob too far, not enough material will be coming out to cover the panel!

Now, you’ll notice that I said, “raise the pressure to the gun”, while earlier I said to set it to manufacturers specs. We are talking a very small adjustment. It is a fine balance in material-to-air ratio and a little more air than specified is okay. Even if it is an HVLP gun the inlet pressure recommended is to maintain the 10 lb limit at the cap. Well, about three quarters of the country has no regulations for HVLP use, so if you go over the 10 lbs all it will do is atomize the material a little better. You may lose a little of the benefits of HVLP though. But remember you have a lot of control with the material adjustment knob.

After you are happy with the droplet size, DON’T TOUCH THE FAN CONTROL. It will change the PSI at the cap and will change the atomization you worked hard to get.

Do this sprayout every time you spray as material change, temp, and humidity will necessitate a sprayout droplet pattern test. Good luck!

Do it yourself questions: how to use a hvlp spray gun

Do it yourself questions: how to use a hvlp spray gun
When using an Hvlp spray gun the painter should be aware of a few things. These are pressure adjustment, fan adjustment, fluid control, changing the pressure to match the spec sheets, painting, and proper pressure.

To adjust the pressure, open the compressor regulator to about 90 pounds per square inch (psi), so there is enough air pressure in the line to the gun. Now, pull the trigger on the gun and set the regulator on the gun’s handle to 50 psi or what is advised in the instructions for the gun. Close the valve at the bottom of the gun handle and while continuing to pull the trigger the trigger open the valve on the bottom of the handle until the air volume remains steady.

Adjusting the fan is accomplished by opening the fluid volume control, located at the back of the gun, about 3 turns. Close the fan control located on the left side of the gun behind the nozzle. Position the gun 6 to 8 from a test surface, move the gun across the surface and pull the trigger. While moving the gun, adjust the fan control until the desired fan shape, usually a 5 to 6 inches wide top to bottom oval shape, is accomplished. If spraying up and down on a surface, change the nozzle at the front of the gun 90 degrees to create a horizontal fan.

After adjusting the fan, continue spraying and adjust the fluid volume located at the back of the gun for the final adjustment. This adjustment is necessary for correct fluid for the gun speed. This needs to be a heavy volume, but not to the point to where the paint runs at normal gun sweep speed.

After completing all these adjustments, the gun is ready to paint. With 50 psi at the handle, the gun is spraying about 10 psi at the cap. If 5 psi is required at the cap, set the handle regulator at 25 psi. Most guns internally regulates the pressure down based on the inlet pressure while some more expensive guns have a gauge located off the back of the handle that reads the cap pressure.

Observe the item painted and the way the paint is going on the surface right behind the gun and adjust from that position. For instance, to spray a small area, turn the fan down to a small round size. The fluid volume will also have to be greatly reduced at the back of the gun at the same time to avoid runs. The air pressure at the regulator on the handle can be reduced to 25 to 35 psi to accomplish this task.

Remember that a high air pressure will be needed, as per spec sheet, so that the proper atomization is reached and the volume is raised. The higher pressure will lower the amount of runs because the atomization is better. This is important with sealers, bases and clear coats so that a good coverage without runs can be accomplished.

Satellite TV Explained

1) All of the TV service satellites (DirecTV or Dish) are in Geosynchronous
orbit.  This means that the satellites appear to remain stationary over a
spot over the equator of the earth.  The satellites are not really
stationary – they are orbiting very fast around the earth, but the orbital
speed exactly matches the speed of the rotation of the earth, so they appear
to be stationary.  We can all thank the scientist and author, Author C.
Clark who first proposed the concept of geosynchronous communications
satellites back in 1932 (many years before the first space launch).

2) Satellites in geosynchronous orbit have positions – they are typically
named according to the longitudinal spot on the earth over which they appear
to be stationary.  Thus the DirecTV satellite called 119 refers to the
satellite over 119W longitude.  Satellite 101 is over 101W and Satellite 110
is over 110W.  If you lived on the equator and lived at 119W, the satellite
would be exactly over your head.

3) When you put in your zip code in a DirecTV receiver, it does the math to
compute the horizontal direction and vertical direction to point the dish
from your latitude and longitude (assumed to be in the center of your zip
code) to the spot in the sky that corresponds to geosynchronous position
over the ground point 101W, 110W or 119W.  If you live very far North (say
near the US Canada border), the geosynchronous satellites appear to be very,
very low on the horizon – which makes it difficult to pick up signals in
many Northern locations.  Trees or buildings or even the limb of the Earth
itself can get in the way, making it difficult to pick up geosynchronous

4) If you could look up at the sky and see all of the satellites, they form
an arc across the sky.  When you set the “skew” of a satellite dish, you are
making the horizontal axis of the dish line up (be parallel with) the arc
across the sky.  For the simple, “round” receiver dishes, there is no true
skew – since the dish is round it focuses the satellite signals at one spot
in front of the dish, so simply pointing the dish at the Elevation and the
Azimuth of the satellite gets you close enough to pick up the TV signals.

5) The problems occur when you need to see several satellites at the same
time.  If you have a simple round dish, you have to repoint the dish.  This
has been the problem with Dish TV from the very beginning – they put some of
their signals on satellite 101 (I think) and the rest on satellite 119.  So,
for simple round dishes, customers have to repoint their dish from one
satellite to the other.  The best technical solution has been to use an
elliptical dish.  In an elliptical dish, you line up the long axis of the
dish to parallel the arc of satellites across the sky.  Then you mount
receivers (the LNB devices that sit in front of the reflecting dish) at the
focus point of different satellite signals.  This use of elliptical dishes
allows a single dish to see several satellites simultaneously – so you never
have to repoint the dish just to see a different satellite.

6) This is how DirecTV has designed their system.  Their primary signals are
on satellite 101W.  Their additional channels (some local into local
service, much of their Hispanic programming) is located on satellite 119W.
Their HDTV service is on satellite 110W.  I have a “triple” LNB DirecTV dish
on my regular home.  This elliptical dish has been positioned using the skew
setting to make the long axis of the dish parallel to the arc of satellites
in the sky.  Each separate LNB device is at a different focus location,
corresponding to 101, 110 and 119.  You then must have a Switch device that
accepts the signals from the three different LNB devices which then routes
the satellite signal to your home receivers, based on the channels you
select.  This, if I watch CNN which is on satellite 101, the switch routes
the 101 signal to my receiver in my bedroom.  If I change the channel to a
HDTV channel (ESPN HD), the switch connects me to the 110 signal.

7) Each satellite has multiple transponders.  In the old days of analog only
television signals, it took an entire satellite transponder to carry a
single television signal.  When digital television was invented, a digital
compression system known as MPEG-2 was created, which takes a video signal
and compresses the signal into a highly compressed stream of bits.  A
standard definition TV signal is compressed all the way down to 3 Mbits per
second in common practice today.  The transponders on the satellites are now
designed to carry digital bits.  A single transponder typically carries 45
Mbps per second.  So, using MPEG-2 compression, you can get 15 or so TV
signals to fit inside of a single transponder.  You now install many
transponders on a satellite (say 30 or so) and you now can carry 15 x 30 TV
signals – approximately 450 channels.  When you select CNN on your satellite
receiver, the electronics look up what satellite the signal is on (say 101),
then what transponder it is on (say transponder 10), then it decodes the CNN
signal out of the other 15 or so MPEG-2 signals that are inside of the same
transponder signal.  If you change channels to Discovery Channel for
instance, it may still be on satellite 101, but transponder 20.  The program
guide and electronics of your receiver keep all of this straight – all you
have to do is pick your channel.

8) All of this complexity explains some of the behavior you will see with TV
signals from time to time.  You may get CNN just fine, but can’t receive
TeleMundo.  It may be that CNN on satellite 101 is free of clouds, but
TeleMundo on satellite 119 has clouds blocking it.  Sometimes on the same
satellite, the different transponders have different signal strength.  On
your DirecTV set up screen, you can select the satellite you are watching
(101 or 110 or 119 if you have a triple LNB), then move through the
different transponders on that same satellite and see different signal
levels.  An important trick when you point your dish is to find a weak
transponder signal on a given satellite and tweak the pointing of your dish
based on the weak signal, not on the really strong signal that is on some of
the transponders.

9) So, what does all this mean to Bounder owners.  If you have a round dish,
you can only pick up one satellite at a time, which means you have to
repoint the dish to a different satellite if the provider has signals on
different satellites.  If you have an elliptical dish with multiple LNBs,
then you can see several satellites at one time, but you have to precisely
align the dish in elevation, azimuth, and SKEW, else, you will get one
satellite signal but not the other satellites on the arc.

10) To add even another level of complexity, note that most LNBs have TWO
outputs, meaning you can tune in to two different signals on the same
satellite at the same time.  Remember, you are still pointed at one
satellite, but having two outputs allows you to tune in to two different
signals on the same satellite.  In really old installations, sometimes the
dual LNBs were not set up correctly which meant you could only see two
signals at the same time if you were on the same transponder (same
satellite, same transponder).  These problems were corrected many years ago,
so now dual output LNBs can individually tune in different transponders on
the same satellite.

Hi Peter, I paid $134.00 per shock. It sounds ridiculous but they really are
that good. In the beginning the Koni’s were adjustable by the new owners but
the latest models are no longer adjustable. Mine are the later models. I
ended up calling Koni when I couldn’t adjust them. They said they hadn’t
updated the information on the web site and boxes. They now adjust

You would not believe the difference in reduced body roll when turning into
a drive and the elimination of porposing. I-95 rides much better without the
concrete seam jolts too.

I hedged a bit before buying them but after a couple of weeks researching
them I decided to take the chance. Fred turned me on to them and I respect
his judgment. It’s sort of like taking the P30 plunge into IPD/SuperSteer
stuff Bud and I preach about all the time. Sometimes stuff cost more but in
the end the costs are justified.

Do a Google search on the Koni FSD RV Shocks. You might find them cheaper
but consider shipping costs. I had to wait a month to get mine because they
were out of stock. They were waiting for a boat to bring more. They’re
selling that fast.
