Turbine hvlp spray set up12/20/18
In the past I have had a well set-up spray rig with DeVilbiss hvlp guns, a pressure pot and a spray booth.
Time and tide find me with a much smaller shop, no spray booth or equipment, but happily not much need for it ----until, perhaps, now. I've taken on a project whereby I'll need to satin or matte finish the parts produced from about 40 sheets of 3/4" walnut - mdf core. We'll be able to finish 95% of this horizontally. The compressor I have now is incapable with keeping up with a conventional spray gun, hence I'm curious about a turbine systems. Fuji has a "semi-pro" system for about $500. (Might possibly try connecting it to a cheap Harbor Freight pressure pot) I'll be using a water-born polyurethane. My sources for finish are likely S-W, or possibly Atlantic Plywood. I've used post-cat floor finishes on stair treads (Bona)---and have been real happy with the results rolling or pad applying the finish - that is possible also.
How much slower will this be using a turbine powered hvlp set-up compared to my previous experience? These cabinets will not be getting very hard use but/and I'd appreciate any suggestions for a good fast-drying finish with good build. Any add'l comments welcomed.
Well not going to get much for $500, my experience with turbine rigs was not great, personally I would not waste any time on them again. The turbine is compact which is nice, but the sound of a jet engine in the background always made me feeling rushed. You will also be tied to a gravity cup or siphon setup making the gun very heavy with prolonged use, as all your material must be attached to the gun, also the 1" diameter hoses are like fighting a python!!
Further the turbines create heat, so your basically blowing hot/ warm air onto your project, effectively drying out the film as you move across, not the best for waterborne...
In my view I could spit on the substrate and get a better result. We currently shoot a Kremlin AAA, only my two cents.
I agree with Kevin about the noise, big pipe of the turbine. I used a couple but as soon I was able I switched to compressor but if you are using the turbine occasionally they are not so bad. I guess the $500 one is just 3 stages and if you can I suggest to buy the 4 stages that allow you to spray thick material like pigmented lacquer. If you just spray clear the 3stage will be ok
Dan, I was doing what you're suggesting, a pressure pot feeding a turbine gun. I set up a Wagner Capspray and was spraying acrylic lacquer with good results. I'd be surprised if you can find a pro gun & turbine for $500, probably $1000+. What about upgrading your compressor instead of a new setup.
Have somebody come in with a portable (on a cart) Kremlin and finish them in your shop.
Put an ad on Craigslist.
If you are attempting to spray a full 4 X8 sheet of Walnut with a turbine, it is not going to happen.
Bona is for floors.
(40) sheets of 3/4" walnut will cost a couple of bucks to mess up.
If you don't have the facility to finish it properly, why not out source? I'm guessing you don't have the room for a dust free spraying area either. Nor a decent exhaust fan. There will be a ton of dust settling on a 4x8 sheet.
I feel your pain about a small shop. I started in a similar situation a long time ago.
Turbines are loud and heavy. Kremlins are the way to go if able. I would recommend using a new airless pump or a clean airless rental. Wishing you the best of luck and the happiest of holidays.
You may want to try (if you have a small compressor) a low CFM spray gun.
I would only advise the use of the above guns with solvent coatings.
These responses are what I wanted. Especially the feedback on turbines. I'm not interested in plunking out much more than the 500 bucks into finishing equipment --- and that doesn't sound like it would get the job done.
Jobbing out the finishing sounds like the way to go.
Is this post really old or something? Modern turbines like the Fuji 3 stage will spray water-based finishes perfectly fine.
Compressor spraying wood finishes is pretty archaic from what I read at least.
Anyone mind letting me know what I'm missing?
