No idea, but I'm interested. *LINK*

HVLP Spray Gun at Rockler

>This looks like the same unit that Rockler sells, which I have. I bought it to help with finishing the built-in cabinets I was making. It works well enough, but it's very hard to get an even, smooth finish...at least with the varnish I was using. I ended up with an orange peel texture that took a little work to sand/rub out in the end. But that may have more to do with my inexperience with HVLP than with this particular unit.

One thing to keep in mind...many books/articles on HVLP will describe how to adjust the airflow to help tune the spray pattern...this unit doesn't have an air adjustment...only an adjustment for the amount of material to release.

Would I buy it again? Probably. It certainly did make the finishing process go faster. And in the end, I had acceptable results.

>How much oversprayed/waste does it produce?

I plan to buy this unit to spray water-borne finishes. Do I need a spray booth? A ventilation fan?...

My shop is 2 bay of a 3-car garage. I wish I had a dedicated finishing room but that will have to wait....

>Hoa,

I can't comment on this particular unit, but I tend to spray in one bay of my garage with a conversion HVLP gun. You should have an exhaust fan (I use an old box fan with the garage door raised about the height of the fan) to make sure that overspray doesn't settle on your work. Alternately, you can always rig up the Michael Dresdner cardboard spray booth. Use a good 1/2 face respirator with an organics cartridge.

One thought about turbine HVLP and waterbornes-the air coming out of the turbine tends to be quite warm and somewhat moist, which strikes me as less than ideal for waterborne finishes (it's part of why I went with a conversion HVLP gun). I will say, though, that I did get fantastic results spraying (oil-based) spar varnish on an old Hudson double (racing shell) using a turbine HVLP unit years ago.

Hope this helps,

Nick

>I don't know that I can quantify the amount of overspray. There is some, however. Though that's to be expected, especially since proper spraying technique (from what I've read) indicates that you spray a bit past the edge of whatever it is you're finishing before letting go of the trigger.

I would imagine you'll want some kind of ventilation system, be it a spray booth or whatever. I did my spraying in the garage and opened the door all the way. I addition, I wore a respirator, as I didn't want to finish the inside of my lungs with varnish ;)

>For what it is worth, I am at present working on an article for Woodworker's Journal doing a comparison of the various low priced spray systems currently on the market.

It's worth a lot!

>Bob, thanks. I just finished reading all of them and I am more confused then when I started. Should I go for the HVLP system or just buy a HVLP gun for my compressor. Oh well, will have to think about this one for a awhile. Thanks again for your help.

>At lower price points, I think you'll get better results out of a conversion gun. If you buy a turbine system, a chunk of your $99 purchase price has to go into the air source (the turbine), which means the manufacturer cut some corners on the gun. If you use your existing compressor for the air source and buy a conversion gun, chances are that you'll get a better quality gun for your $99.

A pancake compressor is not ideal for powering a conversion gun, but if you're willing to be patient and wait for the compressor to catch up, it will work.

Good luck! -- Paul

>Paul I think that is what I am going to do. The more I think about it, that is all I need for the little finishing that I do. Thanks to everyone for the great help.
