00:00how about a recap before we get started on sharpen my axe number five i received a guitar
00:04from a viewer and during the shipping the guitar was damaged the headstock was actually broken
00:10so instead of fixing his old guitar i decided to get him a brand new identical one
00:15and i said this uh we'll do all the repairs that guitar and then we'll donate it we'll do something
00:20with it uh we'll maybe help some kid out that wants a good less pull so now episode 11 sharpen
00:26my axe this is the guitar that i received and it got broken and damaged in shipping
00:30and the headstock of course is seriously broken
00:44i'm here in glendale arizona to see my buddies tim and harry at atomic guitars so just a few miles north
00:50of the glendale arena is peoria arizona and that's where atomic guitars is and we're gonna go inside
00:54and see tim and harry and get this guitar fixed up hey guys i got something for you hey what you got
01:05all right check this out okay so i'm with uh tim and harry from atomic guitars and we're going to talk
01:10about the guitar so here's what happened let me see the story so basically a uh somebody sent this
01:17epiphone west paul through fedex and they packed it well but it was in a game bag and
01:26ouch yeah owie okay yeah it's work the guys from graph tech gave us a graphic now all right
01:35so that should work yeah that'll work the hardest part about this will probably be the touch-up
01:40fortunately it's the best color to do a touch-up on it's black i have every color of black in one can
01:46that midnight black jet black this is where we're going to do all the repair work um on the epiphone
01:51west paul we do everything in-house we build guitars we do it all by hand we do our own finish work
02:00one of the most common repairs we see on a weekly basis is damaged or broken headstocks or necks
02:07and this is a gibson with a broken headstock this one is a gibson that had a broken headstock
02:11you can't really see anything in the front it's in touch-up process right now
02:16crack is along the edge here you can see that this is a thinner profile neck it's a 60s profile
02:23the headstock's back on i'm holding the guitar by the broken headstock it's not coming apart
02:31it's stronger than it was originally and this is something that once i get done touching up you'll never
02:37see the first thing tim is going to do is remove all the hardware off the headstock now the tuning
02:45keys are secured only with two things the nut and a screw so he'll take the nut off flip the guitar over
02:51take the screw out and that will allow him to take all the tuning keys out the next thing he'll want
02:56to do is remove the truss rod cover to gain access to the truss rod because this is going to be very
03:00important in the first step of fixing the guitar next tim is going to relieve the truss rod
03:06by inserting an allen wrench he can tighten the truss rod and loosen it and what he's trying to
03:10find is where it's perfectly loose so that way the truss rod is not causing any force in the neck and
03:15that allows him to clamp it and make the neck exactly straight when gluing it now that the truss rod's
03:21relieved he's going to start gluing the neck he's going to use tight bond glue it's a wood glue that is
03:26water soluble now this is important because he wants to be extremely gracious with the glue in other
03:32words he wants to really put a lot of glue into the cracks get every kind of spot he can make sure
03:38there's as much area bonding as possible the glue will dry and be more strong than the wood is this
03:45glue is used by luthiers all around the world the best part about it as you can see is he can wipe
03:49the glue off using a napkin or even a wet damp cloth it's very easy to clean up and very easy to work
03:55with now they'll flip the neck over and do the other side you can see there's glue on the fretboard
04:00everywhere and that's what i'm talking about see how he's injecting the glue in it and it runs into
04:05the crack so he's feeling as much area as possible and the most important part is he's getting as much
04:11contact surface covered with glue and that's going to help the neck be stronger and bond a lot stronger
04:17and again very easy to clean up it's a very easy glue to work with that's why luthiers use it all
04:21around the world now he's going to clamp the neck he's going to use a sanding block it's a metal sanding
04:27block and the great thing about this is it works just like a splint for a broken leg the neck is
04:32then clamped to the sanding block which will make the neck perfectly straight the other nice thing
04:37about this using these kind of clamps is he can spread the force across the neck so there's not
04:42too much force that will damage a fret or put too much pressure and dent anything or damage into the
04:48wood and you can see the glue now as it's being compressed the glue is kind of extruding out the sides
04:53and that's all that glue that ran inside there and again that just helps the the guitar get glue
04:58in every spot and it's very easy to clean up you can see just using a paper towel you're going to
05:03get most that glue up now tim will continue to wipe the glue up as it continues to come out of the crack
05:10of the neck this will go on for several minutes and that's the nice thing i said about the glue
05:14is that it can be wiped up with a paper towel you don't need any kind of special supplies or anything
05:20it's not hurting anything because later you'll see he'll use a damp cloth just to wipe up any excess
05:25after it dries a lot of these glues will say set for 24 hours but tim uses a couple days i agree with
05:32this method it's a really good idea because the longer the better in my in my opinion just let it
05:37sit and dry so after tim is sure that the glue has dried correctly he's going to go ahead and just
05:43remove the clamps but now comes kind of the scary part um he's got to check to make sure the glue is
05:49holding the way he wants so what he'll do is he'll put pretty much a really great amount of
05:54downward force you can see he's actually trying to see if he could feel it crack or break to make
05:58sure that the glue is dry correctly and it's strong like i was saying earlier he can clean up all the
06:03excess glue residue with uh just a damp cloth so he's using a paper towel and that's just spray water
06:08he's just spraying some water on the cloth he'll get up all the excess glue right now the interesting
06:13thing about this is you might think that was a really bad break is this going to hold up the
06:20answer is yes the glue is actually stronger than the wood was the next thing about this is interesting
06:28is that it broke in the right direction it didn't headstock didn't come off we don't need to do any
06:35splints or anything like that because the string pressure is going to pull from the face of the guitar
06:40and actually help pull this close so we should never have a problem with it now tim is going to
06:47use colored super glue this is super glue with black dye in it to fill in the chips in the paint
06:53this does nothing to the neck structurally this isn't to reinforce the neck in any way this is just
06:58to fill in those chips so that he can then sand the neck and make it smooth before priming it and painting
07:04it now he's going to use a guitar string to work the glue into the little cracks and crevices now what
07:10he'll use is his airbrush which has accelerator in it this accelerator when sprayed onto the glue will
07:17make the glue dry in seconds this makes this process a lot faster since he doesn't know how many times
07:23he's going to have to fill in these cracks and then scrape and then sand once the glue is dried he'll
07:29go ahead and just use a razor blade to scrape off all the excess to make it smooth it's pretty straightforward
07:34process things we use to sand this guitar and get it level it's going to be this neat little flexi 3m block
07:42thing bends the contours i can flex it that way we get the same shape as the neck next thing we use
07:52some wet dry sandpaper we want to use it wet and we want to be nice cut really well and cut a nice smooth
08:01surface so that's what we use for this part
08:09now we're just feeling it make sure we got everything smooth get it ready for the booth
08:29we'll take some masking tape and get it ready for the color
08:41and now we're going to spray a light coat of sealer
08:57just to protect everything make sure the wood's sealed first tim is going to apply some sealant to
09:04the wood to protect it then after it cures and dries he'll go ahead and blend in and paint the
09:10black now he doesn't paint the entire guitar just the area that has been damaged so this is really a
09:16nice point in the process you don't have to repaint the entire guitar notice how he's staying away from
09:21the headstock to not ruin the serial number or the epiphone custom shop logo now he's taped off that
09:27area around that we saw that so that's all protected only the areas that he wants to be painted are going
09:32to be painted after that cures and dries now he'll put on clear coat clear coat is to protect the finish
09:39but not only as you can see it helps him blend in the old finish to the new finish so it makes it seamless
09:46he'll go ahead and spray off the entire neck and that makes it difficult for anyone to detect where
09:51the new finish and old finishes are after applying the clear coat he still has to sand he has to smooth
09:57out all of the imperfections in the clear coat where maybe it's a little thicker or thinner this also
10:02lets him blend in the way the guitar feels now tim's going to remove all of the tape so he can go to
10:08the last stage which is buffing here he is doing the coarse buffing going ahead and blending in again
10:14the finish to make it look perfect but now he'll be on the fine buffer wheel and he'll go ahead
10:19and buff the finish to a high gloss this is what's going to make the guitar look brand new as you can
10:25see he's just coming around and doing the sides he'll do every spot he'll do the entire neck and
10:30again just to make it look like a perfectly new and perfect finish now tim will reinstall the tuning
10:36keys back on so he can go to the last stage which is installing the nut now tim's going to install
10:41the nut now the nut is a tusk nut that we got from graph tech so it's pre-slotted but even then it has
10:47to be fitted so we'll have to do a little bit of sanding on the nut to make it right now the other
10:52thing he'll have to do is make sure he takes a square file and clean out all of the glue gunk and
10:57anything else that could be obstructing the nut from having a hundred percent contact with the wood
11:02when it comes to installing your nut you want to make sure that there is a hundred percent contact
11:06you don't want any gaps you don't want any kind of raises in the the finish you don't want anything
11:12to obstruct transferring the vibration into the guitar put the nut on you don't need a lot of glue
11:24just a couple of small dabs i like putting them in this little slot right here
11:29put one two on either side and push it on hold it there for a minute that'll set that voila that's on
11:50now the strings are on it's tuned up and the neck relief has been set
11:53tim is going to measure the height across the first fret this set of frets
11:57it's at
12:0237 thousandths so we'll take our feeler set here
12:10and i like going just a little bit taller just to make sure
12:16that i don't cut it too low so we're going to take 18 plus 20 is 38
12:21take up this nice jig here you can pick that up you know where i'm going to set it up against this
12:33and i'm just going to tighten it down
12:37so that way it holds it in place for me all right we're going to take a set of nut files
12:41and do the cutting now this is a set of 10 to 46s so grab the nut file 50 to 60 get those at stumac
12:56now how i cut these is i'll actually start the back first aim towards the nut
13:02and actually towards the tuning key so it follows a string path
13:07and i'll take long even swipes
13:14try to take them in one direction you can work it back and forth
13:17rock the the nut you know the cutter just a little bit
13:21what i'll do is i'll stop i'll actually cut a little bit deeper on the back side
13:31just like that
13:35blow off the area and i'll actually stop when i get to the feeler gauge
13:40and i feel the feeler gauge all right so that's now cut the right depth
13:44just drop the string back on it it sits right on there ready to go
13:52next one will be 36 it's 46 36 26. i'm going to cut it with 36
14:00but i'm going to rock it a little bit back and forth just to make sure the slot's nice and
14:05wide enough not too sloppy same thing cut on the back side first
14:11cut some nice long strokes don't work it back and forth just nice long strokes a little bit of angle
14:21just do the back side here kind of got to work it back and forth you don't hit the headstock
14:30and
14:33touching that feeler gauge so i'm done and you just work your way across
14:38the board that way i like taking the soft brush clean off any of the dust
14:45and i'll check
14:48hey nut heist perfect now i'll retune it
14:53and this guitar is ready to rock so here she is and she looks beautiful i mean it looks like a brand
15:00new custom epiphone les paul and i want to thank tim and harry to tom of guitars for that i told him i
15:05said look i want to donate this guitar to somebody that can start their musical journey
15:09but i don't want to give them something that's just kind of like put together or damaged let's
15:13give them something brand new again i want to point out also that tim came in before and after store
15:18hours so not to affect his current customer load i actually lent him a gopro camera and he did all
15:23the footage himself too and that's another thing to point out that was really nice of him so he had
15:27to do the work and do the footage so where's the guitar going to go it's going to the alice
15:31cooper's solid rock foundation they allow kids to get free guitar lessons bass lessons even provide
15:37space for kids to play music with other kids and if you would like to help you can get involved by
15:43becoming a sponsor or donate this is a very very worthwhile organization and they're doing a lot to
15:49help share music with a lot of youth so we're going to give this guitar to them and i'll do a video
15:54later showing that and how you can help them episode number 11 of sharpen max as promised to you this
15:59guitar is going to go to somebody who can really use it and until next week know your gear
