Well if you look a few listings down you'll find that I was not to thrilled about some of HVLP's inexpensive valve.  In my quest to change the valve I wound up with you see below.

Great posting!

That is exactly the HVLP setup I have, and have yet to use.

Thanks!

vteknical,

I have a 4-stage Fuji HVLP unit, too, but I am still using a small plastic cup screwed onto the lid which is attached to the underside of the gun.  That lid has an inlet to enable supply air to pressurize the interior of the paint cup. 

As you probably already well know, having the cup attached to the gun limits how you can orient the gun (not recommended to turn on its side or upside down) and the ability to reach into small cubby holes.

In your modified setup, what is the tall ?stainless steel? fitting screwed into the top of the paint cup?  Is that from HD, too?

I'm still using the nozzle/aircap supplied with my gun, which seem to work OK with Target Coatings (Oxford brand) water based shellac, lacquers and sanding sealer, and alcohol based shellac.

I have not yet tried to use my HVLP gun with any type of paint, but would like to -- to make some 'Sysports."  What do you mean by "lower viscosity paint?"  Is the paint you are referring to thicker (higher viscosity) or thinner than the Target Coatings (Oxford brand) water based coatings I have used?

I sure like the idea of that presurised liner.  However I have an earlex 5000 and its not on the list of adapters.  I've been thinking about getting another set up but not sure what to get.  I wonder if it will it work with an LVLP conversion gun?

Good idea, I will call them before I buy a new gun...Who knows maybe they do have something in the works for the earlex.

Is there a chunk missing from the beginning of this thread?

Yes. vteknical's original post consisted of about 164 words and at least one photo, but as you can see, he edited it on 12 Mar 2009 and now only the first paragraph remains.

If you PM him, he may be able to give you some information about his HVLP modification.

sadly I removed 95% of all my posts due to a misunderstanding with previous management.   I was surprised that no one responded to my post since many third parties were selling this setup for 10x what it cost to actually build/buy.

I will try to locate my original pics shortly.   So far, this has worked terrific!

That would be great! With over 1000 "views", your thread has attracted quite a lot of interest, so it would be good if you could add some photos and describe what you did.

Many thanks

Forrest

I found some photos of my paint setup.







Most HVLP's supply the tank pressure after the ball valve.   I found placing before the valve using a different ball shut off with a bleeder before the ball valve afforded me constant/consistent psi for the 3M Cup.
This heled push thicker viscosity paints through while keeping the pressure down.  The other way around I found myself increasing the gun pressure to increase tank pressure, causing more over spray.   Please forgive if I am butchering up some of this terminology as this is not my primary job.  After using inexpensive Harbor Freight type guns that cost between 10 and 40 bucks that weren't that bad, I guess I was a little disappointed at the quality(fit and finish) of HVLP turbine guns costing much more.

You strap the PPS cup to your waist? Great idea!

I also have the four stage fuji and have had no trouble at all spraying latex paint.  I do thin it a bit which means I have layer a few more coats but it lays down a very smooth coat of paint.  Very professional looking.
