I have done fantastic finish work with an inexpensive touch up gun from harbor freight. A larger compressor allows you to spray longer without waiting for the compressor to catch up. Not a big issue for guitars though. You could also just use an HVLP system with a turbine. There are some models that are not very expensive.
@naminnooman Thank you. Glad you liked the video. I think that is a devilbiss finish line gun. Basically any gun will work if you have the correct needle size and set up your gun properly, correct flow, correct pressure, correct viscosity etc.
Have you tried the Devilbiss FLG4 (finish line). It's fairly inexpensive and I find that it sprays much nicer than the Startingline. It's also lighter, and comes in a water-borne compatible version if you're interested in that at all.
@naminnooman Basically any compressor will work. However, you want it to have a enough power and capacity to not have to wait for the compressor to "catch up" It needs to be able to supply constant air flow and pressure to the gun. On the green guitar I am applying lacquer clear topcoat over dyed maple and shellaced
@187MIAMIBOY Smaller needle sizes are for low solid products like stains and dyes and larger needle sizes are for higher solid products like lacquer and urethanes. Usually a needle between 1.3mm and 1.5mm will work for most products and applications. You can also thin the products you arer spraying if they are not atomizing well
I spray three to four coats a day and then level the next day before spraying another three to four coats. I spray usually 2 or 3 days before wet sanding and buffing. Don't forget to let the finish cure before attempting to level and buff
I arrived at the same plan. It's great to hear you say it in a couple sentences, Thank you. Great tutorial. Crammed with great info and less than 10 minutes. Way to master the new media.
@COlson1968 Thanks for the feedback. I always tell my students that if you want to really learn how to finish, go talk to the car finishers! They are the masters. Happy Finishing!
Excelente Robby, como siempre un video muy detallista y simpático, a veces quisiera golpearme la cabeza por no haber aprendido inglés, bueno... escuchando varias veces puedo entender bastante...gracias maestro... bendiciones. "Juanca"
@presleep Thank you and good question. I am using an industrial spray booth. This thing is very powerful and will suck the hair off the top of your head, if you have any. I am spraying away from the photographer, using an HVLP spray gun and all of the overspray is very quickly sucked up into the booth filters. Notice however, that I am wearing a mask cause I am much closer to the surface I am spraying.
what a fantastic video! The very best out here. What spray HVLP would you recommend? Is that a DeVilbiss Finish Line you are using? Your help and recommendation would be of great help. Thank You so much once again
That depends...are you going to re-coat it with the same type of finish? If so, then sometimes a light scuff sanding and then you can re-coat. However, if you need to fix imperfections in the wood then you will need to completely remove the finish. I use a combination of scraping, sanding and stripping to do that.
a guitar player from central illinois. he had someone custom build him a guitar and it looked a lot like the guitar at 25 seconds in... sorry if it isnt, i was just wondering
There are many things that can cause bubbles. Usually this comes from the surface skimming over before the air has a chance to escape from the finish. You have not told me what finish you are spraying but I would probably start by thinning it a skoshe and spraying lighter coats.
Love that buffing wheel.Painted cars for 20 years now wood finisher for last 10.the only thing I would do different is sand in one direction no circles on light colors no difference but dark colors outside after a while will look like a spider web.I have done some hi gloss jobs on wood with car clear but you have to spray polyester (nast shit) sand 180 then clear,looks great lots of work.Closet Organizing Systems web site has a gloss ebony job I did a while back.
@187MIAMIBOY You get what you pay for obviously. You can use the same gun but depending on the needle size you might have to thin the produt to get it to spray better.
good video! you should use a paint sock on your head sometime it can get into your ears and hair, also try a larger water filter mounted on the wall with silica unless you already have one, I use a sharpe one and a devilbiss desiccant air dryer snake hose, water is one of the biggest enimies of painting,
@OBrienGuitars Not opposed to all types of capital punishment or just hanging! ;-) Nice video by the way, I'm about to buy my first HVLP gun, thanks again!
Thanks so much for your response. I went and checked out a few compressors today. But was confused. What is the Compressor capacity and HP you would recommend for guitar finishing? I mean ONLY guitar finishing without having to use the same compressor for other jobs in the workshop. What is the finish that you are applying on the green guitar? Is that Nitro/polyester/polyurethane or acrylic urethane?
Okay, thank you for pointing me in the correct direction. I found a ridiculously low priced spray gun on from Harbor Freight. Now, I need to find an air compressor to use. Any recommendations?? Unfortunately, I LITERALLY have no clue what I am looking for. Sorry. I literally want the cheapest air compressor I can buy that will get the job done. I do not need something HUGE, due to space constraints, so the smaller, the better. I do not know ANYTHING to look for...PSI? Size? Hoses? Connectors?
Thanks for posting this video. When re-finishing an old acoustic guitar, would you recomend stripping it to bare wood? ..What would be better , sanding or paint/finish remover ?
@HarderThanCalculus He is disposable. haha No, really, the spray booth I use will pull the hair off of your head it is so strong. Believe me, no fumes or overspray came anywhere near him. He wanted to take one for the team anyway.
I'm interested in building my own guitar from start to finish, in addition to finishing them as well. I do not have a HUGE budget to accomplish this task with, so I was wondering what is the minimum setup I can purchase to create professional finishes. What is the smallest air compressor I could purchase? Why do you need a large air compressor to begin with? What other things should I consider?
HI I'm Luca from Italy what do you mean with " I sand between days and not between coats? how many coats you spray before sanding (wet on wet)?? thanks best regards , Luca
Very good video! I have been out of woodworking for about 6 years now. I have worked for store fixture companies and kitchens companies. It seems that the whole industry is moving towards those gravity fed guns HPLV's. Has anyone had a good experience spraying water based varnishes? I want to make my self a new kitchen , but I'm not set up for laquer. (No spraybooth). Apparenently laquer still outperforms, but I am sick of dealing with it, even in the best spraying environments.
Fantastic video. Very informative and will help for my first attempt at spraying using HVLP. I have one question though - why does the photographer at 7:08 not need a respirator? :D
what would you recommend for painting a car. A good cheap one since am on a budget. Also could i use the same gun and canister for primer, base coats and clear coats?
hi! can i ask you something?? i need to paint a white guitar and i dont know what kind of paint do i have to use, im going to paint it with a spray gun, thanks!!
I recommend calling Jeff Jewitt at Homestead Finishing products and explain exactly what you want to do and what material you want to use. He can help and even has spray systems specifically for luthiers.
I am curious about the fret board. When that gets lacquered how do you protect the frets? I just spray and scrape but do you think painters tape would be better and just tape the frets? This video helps. I have an issue with drying times on can spray and will try this instead. Right now after 24 hours of drying I still get imprints from what it is lying on which is a t-shirt.
I mask off the fretboard. This solves that issue. 24 hours should n be more than enough dry time to not have something imprint on the surface unless you are spraying extremely thick layers. Check your humidity level where you are spraying too.
Where is a good place to buy nitrocellulose paint that is compatible with a spray gun. I want to do a classic sunburst one one guitar and a solid color on another. I want to make sure I get the right paint before I buy.
Hi there, I've got a beautiful idea to put some pressed flowers on my acoustic guitar but I'm afraid I might ruin it. I was wondering if you could give me some advice if there is some kind of spray glue I could use to put them on or should I put a whole extra layer of varnish on top? The varnish seems to be a bit expensive, I'm looking for a cheaper solution if possible. It would be amazing if you could give an idea how to do it! Thanks a lot in advance!
+mario urbina There are several types of clear coats. Some are water white and others have an amber color. Some are formulated for wood and others for metal. Sometimes they can even be used interchangeably.
where are you putting the guitar so that it will dry? your holding it in your hand and not showing us what you did to let it dry. Not being sarcastic but why are you holding the guitar and not hanging it up?
Great video! Nice to see how you set up the spray gun!
Thanks for watching and happy finishing!

Eastwood/Binks are the ultimate spray guns,the ultimate!!
Great video.Very informative!!
a quick google search brings up several that will suit your needs. I would start there.
Good luck.
jajaja you are amaizing luthier and really cool and funny on your answers xD thank you very much ...very great videos¡¡
NO, however, in the upcoming online electric guitar building course we show how to bind and finish a Les Paul. It should be available early in 2014.
I would use a white lacquer. You can make it yourself by adding pigment to clear lacquer or purchase it already mixed.
There are many things that can cause bubbles. Usually this comes from the surface skimming over before the air has a chance to escape from the finish. You have not told me what finish you are spraying but I would probably start by thinning it a skoshe and spraying lighter coats.
It is the figure in the wood that creates that effect. It has just been sprayed with a clear topcoat.
Glad it worked.
Happy Spraying!

Sure, this is a nice system and will suit your needs.
@OBrienGuitars
Thanks for your reply !
I sand between days of spraying and not between coats. I usually sand with about 320 grit paper.
@believin13 Clean the gun better after use? Try some lubricant on the trigger?
I probably have. I have tried many guns over the years.
@187MIAMIBOY You get what you pay for obviously. You can use the same gun but depending on the needle size you might have to thin the produt to get it to spray better.
@foxybrown2 I have always done it this way and never had a problem. I am not opposed to hanging though

What cfm capacity air compressor would be good for hvlp gun for guitars
Hi - agree with others very informative video. Just one question - how do you hang the freshly sprayed guitar to whilst the finish dries?

@Bluestouse86 NO. Who's Roy Ponce?
@OBrienGuitars so the thinner the needle size the better? and then just adjust the gun settings accordingly
Where can i grab a copy of the electric guitar building book? The videos are great by the way

Hello , question in looking into buying a small compressor and spray gun. What do you recommend i will be using to spray bass guitars ???
I recommend calling Jeff Jewitt at Homestead Finishing products and explain exactly what you want to do and what material you want to use. He can help and even has spray systems specifically for luthiers.

How many polyurethane varnish do you use in each classical guitar?
I can do a guitar with a quart.
I believe this was the old Mcfaddens brand lacquer
Thanks dude, but what kind of paint do you use??
Rob, do you recall the nozzle tip size?
Interesting thing is, you wear a great repirator and mask for protection, but what about that guy standing right next to you while you were spraying?

Whats the song at the 6 minute mark?
Hi there,
I've got a beautiful idea to put some pressed flowers on my acoustic guitar but I'm afraid I might ruin it. I was wondering if you could give me some advice if there is some kind of spray glue I could use to put them on or should I put a whole extra layer of varnish on top?

Thanks a lot in advance!
Epoxy resin
try colored lacquer
sorry what I mean was what kind of laccquer : nitro , polyurethane , urathane or...??? this is my last question !!! thanks
why are you holding the guitar and not have mounted. That seems like that would be a pain to try to paint and hold the guitar.
I have an electric guitar building dvd available at apprenticepublishing
I see. I won't bother to ask you how you like it then. Nice video by the way.
Brad Angove It's because you didn't use a question mark! 😜
@foxybrown2 it works for me.
Hello, I WANT To ask you about the clear code? Is that universal clear, the same thing they use on the new cars to protect the paint?
?
+mario urbina There are several types of clear coats. Some are water white and others have an amber color. Some are formulated for wood and others for metal. Sometimes they can even be used interchangeably.
can you recommend me one brand for wood ? thank you for the help
+mario urbina Behlen's makes a user friendly instrument lacquer.
A small pancake compressor would probably work.
I hang the guitar after spraying and let it dry.
Você aplica goma laca com spray gun?
Sérgio De Souza uso French polish para aplicar goma laca mas pode usar pistola também
OBrienGuitars obrigado pela resposta. Vc poderia postar um tutorial de como fazer?
OBrienGuitars no Brasil não conhecemos aplicação de goma laca usando spray gun.
tenho um curso no meu site obrienguitars.com/courses/french-polish
I think it was nitro based
where are you putting the guitar so that it will dry? your holding it in your hand and not showing us what you did to let it dry. Not being sarcastic but why are you holding the guitar and not hanging it up?
