feedback on Les Paul Headstock repair

I need some suggestions from the many great repair senseis out there.The customer is fine with a structural repair and not concerned about making it invisible. I told him you will see anything I do. He was fine with that and has a budget of between $700-1000. It's a clean break. nothing missing, It closes tightly.. I was thinking either 1) the generic double splines one on either side of truss rod and touchup as best I can. Or 2) the ab…

With a break like this with plenty of surface area, I would just glue it without any additional supports. My glue of choice is hot hide glue, but there will be lots of opinions on that and many option…

D28 blowout

Hi all, I'd like to get some input on how to address this top blowout. For starters I own this, I got it as a project guitar, 71 D28. I'm not as experienced with acoustics as electrics and this is a big project but I got it to learn new skills and I'm confident I can do it with guidance. It had been stored in the case for many years under tension and was way too humidified. The bridge had pulled up I assume in stages. The center seam se…

Martin D-35 with cracks everywhere!

Hello looths! Long time lurker, first time poster here all the way from New Zealand. I have recently acquired this 2008 Martin D-35 for a very cheap price ($1000 NZD - around 600 US!) it's dried out in a very cold environment and has two substantial cracks running all the way across the top, one large side crack, and a previous side crack repair that's been done quite poorly. I'm only about 3 years in to this repair journey and this is d…

I thought I might add an outlier of an opinion here. I understand the temptation to close the cracks with higher humidity, but you're asking a lot of adhesives, reinforcements and human attention span…

Spanish Heel failure

Hi all, I got a Do Santos DSMSCC RC in shop, the Spanish heel has failed , or rather collapsed into the soundboard, splitting it on both sides along the grain, a broken brace just under the fingerboard extension , cracks on both sides on the top/side bindings, I measured wood humidity on the fingerboard 9% and inside the (very inaccessible) body 11% The normal procedure would be to re-humidify before jacking or clamping back into place ,…

Local Thrift Shop Find: Gibson Ivory Top A3 Mandolin

A customer brought in a Gibson ivory top A3 mandolin. It's in good shape and has all the parts. He found it at the local thrift store here in Bishop. He wants it mechanically sound. Here are the problems: 1) Everything that comes into the shop has a shrinkage component and the effects of course very from instrument to instrument. This instrument is no exception and the results of that shrinkage, in this case, are severe. The top, ba…

Retopping a ladder braced Stella - dimensional questions

I am repairing a damaged Stella parlor guitar. The original top was birch, plain sawn at 0.100 inches thick, ladder braced with multiple beefy braces and irreparably split, warped and generally separated from the sides. I want to keep the instrument ladder braced with a movable bridge and upgraded tailpiece, all firsts for me. I would be grateful for input on 2 issues. 1. The new top is Adirondack spruce that I’ve reduced to about 0.110…

Gibson MK-72 Body Damage

All - looking for recommendations on overall approach for repairing this nasty side crack right at the edge of the tail block. My initial thought is that either the top or the back needs to come off in order to properly glue and clamp the main split. Thanks in advance. Images

I use a file or a sanding block. I fit the new side by pulling sandpaper (like on a neck reset) to start and then finish with a little bit of chalk and futzing. You could pull the tailblock inlay and…

Help needed to pinpoint my mistakes please!

Hi all, I am a newer guitar tech and after dozens of repairs this particular Simon & Patrick Luthier Cedar top SP6 acoustic dreadnought from the 90-ies with a bolt-on maple neck has been an incredible challenge. It came with a maxed out and stuck truss rod with a considerable up bow in the neck, extremely low saddle with barely any string break angle, so it needed a neck reset. Later on I figured out that it also has a pretty dras…

So what about Re-tops then…. (on a vintage D-35)

Hello again folks, how is everyone! So I'm curious about what people here think about re-tops, who's done them, and what sorta ballpark rates you've charged for past completed jobs. I've got a bit of a wild one here, so strap in if you've got a couple minutes for story time! Back in 2012, I traded an HD28V of mine for a cool 1966 D-35 that needed some work. Basically, the body and neck of the guitar were fine apart from…

Do I need a refret?

Hi, thanks for this great resource. This is my first post here. I work on my own instruments and have little experience with advanced repairs. Recently I acquired a ca. 78 Sigma DR28H. I bought it because it sounded great and came with a pickup installed. I wanted something for open mics and gigging. With light strumming it sounded fine but I found some buzzing when I took it to a jam. I made a nut and saddle , adjusted the truss…

1986 HD 28 Neck Set

To repair previous "repairs" I removed the back of this guitar. I'm considering setting the neck by slightly pulling the block back whilst gluing on the back. If the seam on the bottom of the guitar where the back and sides meet is within easily workable amount (see by doing a dry run) then hmmm...the concept has my attention! I could otherwise just do a regular neck set. Votes? Thoughts?? Images

I've done this a couple times, but I learned my lesson the hard way. I believe this method induces additional tension into the body of the guitar. This internal tension will then present itself at som…

New Acoustic Build - Having trouble

Hi all. Brand new member. I’ve been building a classical guitar via kit from LMI for a couple of years now. I keep putting it off but recently became motivated to get back to it. Unfortunately LMI is out of business so I now have no one to go to to ask questions. I’m at the stage where I’m putting the sides together in the form. I followed the dimensions for the form based on the plans as I measured them, but the sides overlap pretty ba…

Structurally you are fine. When you glue this up (this is important), make sure your sides are clamped in the form VERY snug so there are no gaps between the sides and the forms. This will leave the…

Yamaha FG 75 Heat Probe Locating

I added measurements for the Yamaha FG red label FG 75's some time ago. I Keep getting these in for neck resets. I wanted to add photo's from the first one because they show that the dovetail joint does not align with the first fret beyond the neck/side to make folks aware so that one knows to slightly angle the drill to hit the pocket. I do the same on the holes drilled at the fret at the side/neck fret. I slightly angle the drill…

Tiny fret slot blues

Hey lads I'm in a bit of an indecisive spot with a 70's yamaha acoustic refret. Pulled the original frets and the tang is .018" with no barbs just divots pressed into the lower edge. The slot is measuring .018". Struggled to find any suitable sized fretwire in stock in the UK that match what the customer wants that'll fit in the slot. Sintoms looked ideal but couldn't find any, so went with something with 0.20 tang and they're not pressi…

Yes, a dremel is not ideal. Ideally you want an air tool with tighter tolerances. Do you have any pawn shops or junk around your shop? Practice on something, you will get a feel for it.

Seagull Acoustic Neck Reset...

Hey everyone, I wanted to do a bit of a follow up on a repair I'm doing. A customer brought in a Seagull acoustic guitar that had been dropped, causing the heel block to separate. I managed to get that glued back together with pleasing results, however I did need to take the neck off by removing the two bolts which thread into the heel block, and unglued the fretboard extension. All went well here, although I'm left with a situation whe…

How would you tackle this airline damage repair?

(Just to set expectations, I bought this for the sole purpose of learning. Not a client project) I got this Martin D28-12 in destroyed condition, after an airline did something awful. As I see it: - Top cracks - Back cracks - Top & side separation with some broken off kerfing - Brace ejected When I was looking at the pictures online pre-purchase, I thought I might take the neck off and re-top it, or at the very least, take the top off and fix…

Missing soundhole braces Gretsch 6021 Town&Country Rancher flattop acoustic

Technically this is a repair, but I thought there would be some crossover with building, so I posted here as well. A 1950s Gretsch Town & Country Rancher 6021 is missing the two braces on either side of the sound hole (see photo). Because this is such a wide instrument (17” lower bout), I’m thinking that installing those missing braces will help with the stability of the top in addition to repairing the cracked/loose ladder braces. The…

Vintage Yamaha FG Neck Resets

I've completed 89 vintage FG neck resets. https://yamahavintagefg.boards.net/ See the Repair section. As others have noted, the joint is very tight, and they put glue in places it shouldn't be, like gluing the face of the heel to the side of the guitar. I've done a few that were fairly easy, and a few that were brutally hard, but the rest were very difficult. A few had little to NO neck pocket! All with steam, and a neck press of my…

I have some SolidWorks 3D models of a few neck joints. What's a good file format? It helps to have an assembly and parts to be able to see how they fit together.
