Bought the earlex system came with the giant 2mm needle no shocker it’s a pain with real thin finishes.

Anybody have one?
What’s the ideal needle size for laquer.

I’m running the 2mm now thinned it way down with retarder and laquer thinner. Test piece looks good, and then the actual piece never lays down. I went 8:1:1.

What dilution and needle do you use. Compressor and gravity feed used to wake the kids, but I can’t get this dialed in

1.3 is a standard tip size for spraying finishes.

What model is it? Seems like you be able to get a needle and tip for it.

Thinned to about 50/50, and spray with the smallest tip you can find. the 1.0 is what I used on my Earlex 5500. Thinned you have some work time in the can, but if I stop for very long at all I clean the tip.

A couple of good links.

Videos here, and also a bunch at You Tube, just put Earlex, and your model number in the search bar once at You Tube.

I use the 1.3 tip on all my lacquer, mixed 50/50 with thinner. Great results and very happy with the sheen and finish.

Check the mfg data sheet on your finish material.
Every mfg selling spray coatings, gives some kind of advice on tip sizes for different guns.

Don’t own a turbine unit, but use enough different guns to offer background information:

Pressure cup (found on most Turbine HVLP) sprayers tend to prefer a slightly smaller spray tip size than normal HVLP gravity feed spray gun. I use 1.2-1.4mm for thin materials like lacquer with gravity feed and 1.0-1.2 for pressure feed cup gun. IME a 2mm head on pressurized cup gun is best for heavy body finishes (latex & auto body primer with heavy filler), and is similar to a 2.2-2.5mm tip on HVLP gravity gun.

Many lacquers can be sprayed straight from can, without need for thinning. But it all depends on brand, and solids content. Here in AZ, will add some slow lacquer thinner and retarder due low humidity and high temps to help prevent dry spray edges on large panels. In winter, only use couple % retarder on large panels.

Would be cautious attempting to use 2mm tip on lacquer as you might exceed the recommended film thickness recommended for lacquer? If you are virgin to lacquer, read up the dreaded crack/craze issues during moisture/temp cycling.

Best Luck.

I have the 7000 (or ii it 7010)? Three stage, but the gun looks the same as the cheaper ones (blue anodized).

I tried the stock needle with some precat lacquer and it was a mess. Several other attempts also were not so good and I haven’t had a need to try again, but I did buy some of the other needle sizes. I’ll follow this as I can use the same advise 8^)

Here’s a link to the Earlex needle recommendation from Highland Woodworking for the 6002 and 6003 Pro-8 SprayPort guns (pressure and gravity). Highland WW

In my limited experience with the 6003, I select the smallest recommended needle/cap/tip for the finest atomization I can get.
