spray gun needed

spray gun needed · 11-05-2009, 08:39 AM

hey guys i need your imput.
I am taking a big step toward investing in a spray gun. I have a compressor but I really don't know what kind of gun to buy. I will be spraying some dyes, water based finishes and some poly.
I have looked at the guns at lowes and Northern tool but it just confused me more.
Any reccomendations for a good quality gun at a reasonble price?

I really depends on your compressor capacity. I think the HVLP guns are the way to go, but you typically need a bigger compressor since they use a lot more air than the pancake or hotdog compressors can generate. I have tried to find a good spray gun that works with my pancake compressor but have only been frustrated. If you have a larger compressor, go for a good HVLP gun. There are HVLP guns from ~$40 to over $300 so I will avoid making any recommendations there...

Depends on what you want to spend too. The Vasper (sp?) guns that Northern Tool sells are pretty decent for the price. I used one for paint (with a 2.3mm tip) and it worked great. Another suprisingly decent cheap one is the HVLP from Harbor Freight. Lists for about $60, but you can find it at times for $20-$30 on sale w/ coupon.

If you go to a turbine system, and still don't want to spend a ton, check out the $100 offerings by Wagner (FineSpray), or Rockler/Harbor Freight. I had the FineSpray and got EXCELLENT results.

Now if you want to spend some real money, I'd recommend getting into a turbine system. Several makes and all seem to be just a variation of great. Earlex, Fuji, Apollo, just to name a few. I have only used the Fuji Q4 and it's excellent, just pricey.

As said, you will need a larger compressor for HVLP, but that is definitely the way to go. Mine has a 20 gal tank. I bought the set of three guns - Titan, from Amazon, about $130. They have been very good for my projects.

I highly recommend HVLP. Conversion guns that I have used and seen good reviews on include Porter Cable, Wagner, titan, and Vasper. The conversion guns do use a lot of air. The true HVLP systems are a good alternative. The Earlex gets good marks, and I have seen positive reviews on the Harbor Freight.

If it were me, I would make sure whatever I got has a stainless steel or nylon cup/pot. No regular steel.

I purchased a HVLP thru Rockler. It was only 4$9.00 but have had great success with it. I spray mainly water based lacquer, oil poly and stains. For the money I have been very pleased. The only drawback is that the instructions are sparse.

In younger more nimble days my previous hobby was customizing cars. I've owned and used several different brands and types of spray guns. From cheapo no names all the way up to the extremely nice and overly priced Sata units. I sold most of my more expensive units because, well, I just didn't need em to finish wood. I still have a half dozen or so guns, but about the only ones I use now are:

A Badger airbrush for tiny shi.. errr stuff.

A cheapo HF unit for base coat work (they actually sell one that's fairly good. Can't remember the part number though, I'd have to look. I wouldn't buy any of the others they sell.) I bought two of them the last time they were on sale. A deal at $19.99. Gave one to a friend and one is still NIB on the shelf if the one I use soils the sheets.

And my favorite. A Tjr from CA Technologies. Not cheap, but as good as most of the much more expensive units I've used. The pattern isn't big enough to paint vehicles all day, but it's great for WW. Small enough to handle well in all the nooks and crannies but still able to flow enough for panel work.

Read this post on woodweb....

then look at the Grizzly lvlp guns. You might get away with a smaller compressor.

Around $40. However dyes will stain the plastic cup and annoy you.

You could upgrade to a lvlp Star gun, and then upgrade that to an aluminum cup.

If you end up going lvlp, please share your experiences.

I've used LVLP for years, and am comfortable with them. Their primary drawback is all of the mist overspray.

Fine Woodworking magazine published a book called "Finishes and finishing techniques." ON page 121 they have a comparison between the spray patterns of conventional high pressure spray, conversion-air HVLP spray, Turbine HVLP spray, and airless spray.

Their conclusion was that "In general, high-pressure and conversion air HVLP systems delivered fine atomization and more uniform spray patterns than Turbine HVLP or airless systems".

I recently purchased a conversion air HVLP two-gun set from Grizzly, but have not yet used them. If I were in your shoes, I woudl go with a conversion air HVLP set and add tank capacity to your compressor if it doesn't generate enough CFM.

One thing to consider is where you are going to spray. I used to do my finishing outside/ in the garage (shop is in the basement), so I got an HVLP Turbine system (Earlex 5000) since it's very portable. No need to lug a heavy compressor around.

My recommendation? Get both

I don't know that I agree with that conclusion. I have a 4 stage turbine HVLP and a couple of conversion guns, and for me, the turbine gives more uniform results. I would expect that mileage will vary as it is dependant upon all of the components and how they work together/inter-operate.

Good point Trav. I recall that their test utilized a 3 stage turbine (the most common). A 4 stage should produce better results.
