This is precisely why Leo Fender developed the insideless guitar. A compromised neck block is super hard to come back from and when I see something like this, it leads me to believe that it's the tip…

'60's Fender Newporter matte finish repair

I working through a long top crack repair on a c.1964 Fender Newporter and need to do a little touch-up on the clear coat. The top coat is matte over a do-do brown stained mahogany top, I'm guessing around a 10-20% reflectivity. Questions: 1. What top coat product did Fender use on these? 2. What should I use that has great self-leveling qualities and will melt into the old finish? <>

I've decided to follow your wisdom, Ian, and it leave the finish cracks alone. It will be structurally sound again and look like it used to have a crack.

My guitar got smashed.

It was attacked by a Martin Dreadaught on a small mountain stage resulting in a faceplant. The top is Redwood. I was able to get it to glue up fairly well and have done some splice and drop fill on the vertical cracks. I'm curious about suggestions for the deep cross grain areas. I am hoping to not re-shoot any lacquer and just rub out the finish with some Kovax dry sanding. It was never high gloss buff to begin with and it's a personal…

@member Thanks Ian, I also have some ultra thin fill&finish on the way. I will do some experimenting with it and see if it can help me out any.

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…

Splines: When are they necessary?

Question about splines: At what point are they necessary? My question is primarily regarding the crack to the left between the bridge and the sound hole as well as the crack at the upper bout that runs along the fingerboard extension. I have already glued them both and used the TJ cleats that run the full length of the cracks. I have already splined the lower bout crack that runs from the bridge to the binding as it was super gappy and d…

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…

@member Man, sorry for the late reply. I would just keep on taking this mandolin apart until you meet serious resistance. I'd build a mold and just trim it until it fits and…

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…

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…

1930 Gibson L-0 Top Sink

Hey All! I hope everyone has been loothing and living as well as possible. I'm checking in to ask for an opinion. I have been asked to fix or improve some top sinking/splitting of a Mahogany top 1930ish L-0 that sits between the bridge and the junction of the X-brace. It's showing signs of wanting to crack further but neither seems to be all the way through the top. I have removed the bridge plate cleanly and have tried wetting the…

Maybe so. Could be a lot of things. I would leave it be. Everything I can think of is either dumb, risky or both dumb and risky.

Martin DX1 plates?

Hi folks. I have a Martin DX1 in for crack repairs. I was feeling around and discovered two huge cedar plates glued to the top. Many gluey fingerprints and spots which leads me to believe they aren’t stock but want to make sure before I remove them. I looked online for a bracing diagram but no luck. Does anyone have any info on this? Much appreciated ! Images

I think it was a ham fisted attempt to address the cracks. I just want to make sure that it wasn't since this model was a ham fisted attempt a going green like Taylor. Laminated neck, bottom and sid…

how to touch this up?

I have repaired numerous top crack on this instrument built by a customer at a guitar building camp. The bridge was off and warped. That has been addressed. After gluing with hide glue and splining the crack these top two did not closed as much as I would have liked. The bigger is about 1/32 at the widest and the other about 1/64. The crack is tight at the bottom. If I can help it I would like to fill it rather than spline it as I have…

Is this hollow body guitar worth fixing - sunken top…

I recently picked up a used custom guitar that the seller said he bought in Vietnam Nam many years ago. I bought it as a wall hanger due to the wonderful Mother of Pearl work, especially on the back. It was very apparent that the top on this instrument was sunken at least 3/8 of an inch, as the weird bridge setup was heightened to the max and there was barely any action height. Once I took it apart and removed the foam inside, I was…

Cracks in acoustic top

I’ve been building electric for a few years but decided to make an acoustic this time. I have some German spruce panels I was going to use for the top. While running it through my drum sander to dimension it, I noticed that both panels have matching 6-8” cracks so the original blank must’ve had a split pre resawing. Would I still have good results if I glue the panels and move on or should I buy a new top set? (I can’t return what I have…

Early 80’s Jazz Bass Fingerboard Separation— Bi-Flex? Washer issue?

This jazz bass has come in with a cracked and separated fingerboard near the nut. I believe this is an early Bi-Flex but am not entirely sure or familiar with them. The truss rod is functional and tightens up when turned. Top of the walnut plug is missing and the washer appears to be crooked or dislodged. Not sure what purpose that washer serves. This is probably the thinnest bass neck I’ve ever seen and it’s no wonder that this fingerb…

Good call Ian, I can definitely get strings on there. I suspect it won’t do well under tension. It’s incredibly thin, neck has pretty much a shallow v profile. Hardly any fingerboard too. Might need a…
