Ok, so after too much research, I have come to the conclusion that with my $500 budget, my woodworking paint needs will be best served by buying an HVLP air rig. My thoughts are that this will better atomize paint than a 3 stage turbine. Since they are both in the budget, the compressor setup seems best because of the future flexibility of it.

Here’s what I have come up with so far. As always, thoughts and opinions are welcomed.

compressor – Husky 30 gallon oil compressor. It says it will do 6 SCFM at 90psi, so i’m assuming that it can at least do 7 SCFM at 40psi. http://www.homedepot.com/Tools-Hardware-Air-Compressors-Tools-Accessories-Portable-Compressors/h_d1/N-5yc1vZbb2v/R-100063473/h_d2/ProductDisplay?catalogId=10053&langId=-1&storeId=10051

gravity feed HVLP gun – Husky. Looks decent to me. http://www.homedepot.com/h_d1/N-5yc1v/R-100378501/h_d2/ProductDisplay?catalogId=10053&langId=-1&keyword=hvlp+gun&storeId=10051

Questions-
Do I need a regulator for the gun? Does it matter what kind of filter I buy for the line to place at the gun?

I use that set up your thinking about. While it does do the job for me I bought the Erlex 5500 turbine sprayer adn love it. http://www.earlex.com/hv5500.php

One thing I have leqrned you can never have a big enough compressor! My compressor has a requlator on it to dial the pressure down.

Good lock let us know what you decide.

I had ordered the Earlex 6900 and cancelled it because others on this forum said it wouldn’t handle latex acrylic enamel well.

I was wondering if I needed a regulator on the gun.

I would suggest calling Jeff Jewitt @ 216-631-5309. Tell him your requirements and he will suggest a few good options for you. Jeff is a nationally recognized finisher and author. I have used him and been extremely happy with the results.

Wow. I didn’t know Jeff was this accessible! I hope he doesn’t mind you giving out his phone number! I actually came up with this rig based on reading his book, Spray Finishing Made Simple. Excellent book.

I just got finished hooking everything up and gave the setup a test run with some water. WOW. What a difference compared to the turbines I have been using! Power. Power. Power. I can see how this can easily atomize some thinned acrylic latex. I had bought a filter but it turns out it was a hard line filter not an inline filter like I thought I was buying. I also bought some type of shutoff valve with a gauge on it that I thought was a gun regulator! So I just ran it straight off the compressor (I broke it in for a 1/2 hour first with the drain open). I think something clogged the gun or it was just defective because the water I was spraying was sputtering. I took the needle out and wiped it and it looked like the tip had been taken off with vise grips or something. It was all chewed up on the nut part of it. I’m thinking this was used because the packaging did look open. Anyhow I’m going to exchange it tomorrow but the gun and compressor had no problem holding 40psi wide open. I could hold the trigger all day long and keep it at 40psi. The compressor kept up, no problem, so I’m extremely happy about that.

Maybe I’ll get to paint tomorrow night.

Update:

I found this gravity HVLP at Northern Tool. I’m still trying to figure out if this is like a Harbor Freight gun because it looked like it was that type of tool from looking at the box. However, it looks like its built and machined well and it worked excellent. It laid down latex perfectly smooth. Very pleased with it. And it was cheap. $40 bucks. The only thing it’s missing is an air flow valve. I’m not sure if that is even necessary since you can control the pressure with the gun regulator. I’ll probably end up buying the 1.8 red gun for priming with shellac.

Am I missing anything by not having an air flow valve (the dial that would be on the base of the handle)?

He lists this phone number on his web site, so I don’t think he will mind. :) He is a great guy and I enjoyed his advice.
