Finishes are a mystery to me. I bet there is a finishing bible out there...

Clodfobble 02-18-2019 10:53 AM

Interesting! I'd never heard of that.

I don't know about a bible, but there was a finishing God.

His name was Homer Formby.

Little known fact: shellac is secreted by the back end of the female lac beetle

Little known gross fact: it's why Junior Mints are shiny

fargon 02-18-2019 12:09 PM

Junior Mints GOOD!!!

Lacquer is secreted by gay male lac beetles?

Clodfobble 02-18-2019 01:58 PM

Lacquer? I barely even know her!

I clearly need to seek help. I got some good pointers from a big guitar forum called Tdpri.

https://r.tapatalk.com/shareLink?url...3&share_type=t


If I were you I would get that paint out of the control cavity as well. Pick your paint solvent and use a small wire brush to get in it out.<br /><br />You have a couple of ways to do this:<br /><br />Wash the body thoroughly with mineral spirits and let dry for 3 days.<br />Get a can of vinyl sanding sealer. Some are great others not so much. DO NOT USE DEFT BRAND! Its never dries.<br />The best would be Behlen's sanding sealer for guitar:<br /><br />http://www.tdpri.com/attachments/h39...e1-jpg.585455/<br /><br />Next. let the sealer dry a day at least and sand to 320 grit.<br /><br />Now you have choice you can paint your color coat directly onto the sealer. Like Gibson does or prime the body Like Fender used to do.<br /><br />If I were you I would prime the body using white sandable primer. I use Dupli-color. It plays well with just about any acrylic lacquer paint.<br /><br />Both Fender and Gibson used acrylic Lacquer under their nitro clear coat which is more acrylic than nitro these days. :twisted:<br /><br />It can be found in just about any auto store. One can is all you need. It relatively cheap about $7.00 YMMV.<br /><br />http://www.tdpri.com/attachments/primer-jpg.585456/<br /><br />Let your primer dry a day at the least but longer is better and sand smooth to 320 grit. A couple of light passes with the sand paper is all you need to do. Any sand throughs cover again with left over primer.<br /><br />Now here is the most complicated part, sourcing your color coat:<br /><br />Most rattle can manufactures, (Duplicolor Perfect Match product line is what I have used) use acrylic lacquer for their touch up sprays.<br />The problem is most companies make paint for the most recent car colors used in the last 5 years and by and large lately they are mostly metallics. It looks like you are using a non metallic color paint. Very close to what Fender called "surf green".<br /><br />So your easiest choices are: 1) Change to a metallic and find something in the same shade or 2) Order a can of Surf Green from Reranch. I did a Sonic Blue Strat some years back and one can is all I needed.<br /><br />A more complicated way but will get you exactly what you want is to take a 3"x 3" color sample of your current spray and taking into an autobody paint supply, they will scan it and their computer will mix out a pint or whatever size you want. At some locations they will even load some of it into rattle cans for you but comparatively this is expensive and you will have much more material than you need for one body.<br /><br />Whatever choice you make the application of your color coat will be the same; 3 overlapping passes = 1 coat is the general rule depending on your technique. Let is gas out over a couple of days between each coat to be on the safe side.<br /><br />After your 2nd and, if needed, 3rd coat has dried completely you can now apply your clear coat.<br /><br />I strongly recommend you get Behlen's String Instrument Lacquer if you want nitro! It has more durable resins in it.<br /><br />One can maybe two cans should do it. They run about $13.00-$14.00 a can plus shipping.<br />Woodcrafters sells the sanding sealer and lacquer so order them together and save on the shipping charges.<br />I think Behlen's is also the retail line name for Mohawk finishes so you might want to check the Googles to source the product from Mohawk to save a few bucks.<br /><br />http://www.tdpri.com/attachments/149254-0-jpg.585477/<br /><br />Follow the rule of 3s for applying you clear coat. Maybe sand lightly your between your second and third coat of clear with 400 grit if you have some orange peel. Make sure to wipe all the dust from the body before applying the next coat.<br /><br />Time is your friend in all this !!! The more time you have between for all your coat applications to gas out the better chance you have for avoiding problems.

Ouch, I knew that, just didn't catch you were using enamel. My bad. :facepalm:

lumberjim 02-19-2019 10:11 AM

I should have done better research on this part. I'm very impatient to assemble what I've created and this looks like a month long process minimum. I'm tempted to put it together as is and play it, then take it apart to paint it in the spring when conditions are more favorable for painting.

Gravdigr 02-19-2019 01:16 PM

Stain it, then paint over it in the spring.

Flint 02-19-2019 03:42 PM

I feel your pain, bro. School of hard knocks.

But when God closes one door he opens another--


lumberjim 02-19-2019 05:09 PM

I have that stuff. Or something like it. Thing about that stuff is the edges. You need to keep it all from sliding off somehow. You could do very thin coats and build it up, or I was thinking of carving 1/2" deep reliefs in the areas where there are no cavities and filling them with epoxy resin. Heavy though. I might do like Digr said. Still mulling it over.

Flint 02-19-2019 05:25 PM

Engraving, filled with epoxy, don't think I've ever seen that. Yeah, heavy though.

lumberjim 02-19-2019 07:19 PM

I've got plans for the next guitar floating around in my head. The head stock as a flame to go with the flamed Maple neck:https://uploads.tapatalk-cdn.com/201...d54df34eae.jpg

And a body like this, but done better:

Undertoad 02-19-2019 07:48 PM

I once repaired a nut on a bass that was actually pulled out of alignment by an offset headstock design. The pressure exerted by bass strings is way more than guitar strings, but still, I'd worry about how much responsibility is on the nut to handle that bend.

Maybe a locking nut... they don't do that on basses AFAIK...

Gravdigr 02-20-2019 09:18 AM

Your headstock design looks like a painter's palette.

Likey.

lumberjim 02-20-2019 06:37 PM

Made a new short handle stick to use, and a taller rotisserie type mount so I can spin the body 360 while I apply finish.

https://uploads.tapatalk-cdn.com/201...9b93cdc930.jpg

I decided to go with boiled linseed oil thinned with lacquer thinner, and some lacquer based pigment. I'll cover it with polyurethane gloss finish as a top coat. I tried a bunch of combinations of oil and lacquer and dye.
https://uploads.tapatalk-cdn.com/201...6a9d4441c0.jpg

The linseed has a slight yellow cast, which helps with the color I want. About 7 parts white, 2 parts green and 1 part blue comes up pretty close.

Very tricky to get it smooth with coat thin enough to use on a guitar. Maybe a telecaster because their tops are flat.

Be careful.

Quote:

Rags soaked with linseed oil stored in a pile are considered a fire hazard because they provide a large surface area for oxidation of the oil, which oxidises quickly. The oxidation of linseed oil is an exothermic reaction, which accelerates as the temperature of the rags increases. When heat accumulation exceeds the rate of heat dissipation into the environment, the temperature increases and may eventually become hot enough to make the rags spontaneously combust.

In 1991, One Meridian Plaza, a high rise in Philadelphia, was severely damaged and three firefighters perished in a fire thought to be caused by linseed oil-soaked rags.

101, I know, but it bears repeating.

It's ok, I've got them wadded up nice and tight and tucked under my box of sawdust next to the gas can.

Gravdigr 02-21-2019 01:11 PM

lumberjim 02-22-2019 11:40 AM

Done work in half an hour, then to the shop! I'm going to run down the body with 0000 steel wool, then give it another coat of goo. The feedback I'm getting from the guitar finishing people leads me to thinking I might just quit with 3 coats of oil and skip the poly. Or just do one light coat and rub it in. The poly won't bond with the oil, they say. Why bother if you're Ok with satin finish, etc.

So we'll see how these next 2 coats go.

lumberjim 02-22-2019 04:34 PM

Still drying, and it darkens as it does, but I'm digging this

The color is correct in the last pic. Close ups come up green

lumberjim 02-22-2019 05:10 PM

Oh, and for now, I'm thinking of leaving the head stock painted with no clear, just sanded fine line this:
https://uploads.tapatalk-cdn.com/201...ada16beee7.jpg
The color is close enough, I think, and the lace wood will look completely different if I do the oil and dye.

xoxoxoBruce 02-23-2019 12:13 AM

The color with faint wood grain showing through looks like kitchen cabinets I've seen in the last few years.

lumberjim 02-23-2019 07:56 AM

We used to do a lot of pickled frost in the late 80s when I refinished furniture. In going to do the next coat straight up white. And only a dash of thinner. Instead of the boiled linseed oil, I'm going with polymerized linseed and beeswax. It's called tried & true oil. Its a food safe oil meant for butchers blocks and cutting boards, but I did the fret holder and those neck rests with it and I love the feel of it. It's bleeding less tint when I touch it than last time, but the color is too dark.
I'm hoping that if I use white, let it sit for 45 minutes and then rub it back, I'll get my color. Then 2 more coats of straight oil in the following 2 days... And then I can convert my shop back to woodwork and start LC0002

glatt 02-23-2019 08:06 AM

Hey. I refinished furniture in the 80's too. Kitchen cabinets as well.

I like how the color is coming out, and am very curious to see it after you add some white.

Can someone show us a pic of something finished in this technique? I'm having trouble finding anything to look at, lots of words, but no pics of pickle-frosted anything, though.

It is a nice effect.

lumberjim 02-23-2019 10:27 PM

Testing with the white. I tried at first with very little thinner, but the white pretty much wiped off completely. 20%or so gave better results. The white gets down in and brightens the non grain wood.

Be sure to copyright that color because The Chinese and con men will be trying to hussle counterfeit LC001s to the huge demand.

lumberjim 02-24-2019 10:02 AM

It's difficult to photograph the color I'm seeing, actually. It's more blue than I can capture. Maybe video in the morning light.


The purple in the knot is pleasing
https://uploads.tapatalk-cdn.com/201...80db8638bc.jpg
And I love the way the white stuck to the tiny light grains.

https://uploads.tapatalk-cdn.com/201...e32177b735.jpg
It brightens the overall color, but there's some depth from the contrast.

It looks pretty home made when I get up close, but I think after a couple more coats of straight oil, it will even out some of the blotchy areas and look better. I just hope I don't lose any of the current color when I do that. It's pretty perfect vs what I had in my head color wise.

Griff 02-24-2019 10:03 AM

Wow, that is sharp.

Interesting, I wonder how a cranberry pick-guard would look?

Gravdigr 02-24-2019 12:27 PM

I'm thinking white, or off-white.

Cranberry would pop, though.

lumberjim 02-24-2019 12:49 PM

I have a white one that I've already modified to accept the deeper intrusion of the neck from the mistake I made with the scale length. I was looking at it last night, and I think I want to cut the lower horn off so it doesn't cover that pretty wood.
Maybe like this

There are clear pickguards.

lumberjim 02-24-2019 03:58 PM

Yah, but then you'd see inside the cavities. Next guitar may have back routed pick up cavities and controls so I can go without one.

Paint the underside of the clear pick guard black or cranberry or whatever where it covers the cavities. You can extend the design to incorporate any image you like, anything that complements the grain and color on the body that needs protection but you don't want obscured.

sexobon 02-24-2019 07:57 PM

Mask off and frost (sandblast) the underside where it covers those areas, put window decals on (H-D?); or, even affix family photos there. Stay away from tacky stuff like hundred dollar bills.

lumberjim 02-24-2019 08:49 PM

Or how about this?
https://uploads.tapatalk-cdn.com/201...f76f999bdb.jpg

I like the creativity though. I've never seen a clear pick guard with the naughty bits occluded. That might look cool. This one has always been light turquoise with a white pick guard, though.

Pick guards are pretty cheap. If the electronics didn't attach to them, it might be cool to have a few choices like phone cases. That could even be a selling point. Just have to design the guitar to mount electronics to the body independent of the pick guard... And maybe come up with a way to change it easily with the strings on.

lumberjim 02-24-2019 09:17 PM

When I tested straight oil on the test spots, it made the blue darker, so I did this penultimate coat with oil and white dye only. No thinner. Let it sit for a good hour, then rubbed back. It gets greasy feeling and is hard to wipe. It softens and gets easier as you work at it. The pic in the last post was the dyed oil sitting on it. This is the result:

https://uploads.tapatalk-cdn.com/201...dbbe0bb559.jpg
It's just a little richer

One final coat tomorrow night, then rest for few days, and then I can assemble the fucking thing already.
