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…

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…

@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…

Repairing small instruments

Im 6'-6" with hands to match. I can squeeze my hands into most flattops, but a friend asked me to look at his 1930's Tiple. It has multiple back cracks that I can get to with props and TJ's crack system, but there are also plenty of loose braces. Looks like I've got to pop the back off, but I feel the long back cracks should be stabilized first. Would you hesitate removing the back? or is there a way to address the loose braces from out…

Those are pretty small, but I think you can get those glued with sound hole clamps. I would at least try it before taking the back off. Take all the hardware off a sound hole clamp and flip one of the…

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…

looking for recommendations repairing big dent - chipped polyurethane finish

Good morning to all - I have another skill building question - picked up another cheapo electric guitar to practice repairs on. I didn't see the big dent, but figured its an opportunity to practice another type of repair. big chunks of polyurethane finish are gone and the bit that's left has a hairline crack around the bottom. I'm thinking to use wood filler to fill in the missing chunks, and want to know if its best to remove the piec…

I don't know, but I did see enough to consider how to best handle it before I start the repair. I can see that the glueboost might be a good way to approach that hairline crack, but who knows what is l…

Advice on getting this 50s parlor nylon back into good shape?

Hi all, I'm new here. I've been playing guitars for ~15 years and recently started as a technician at a music production school in London, where part of my job is maintaining the guitars. I picked up this 50s parlor nylon the other day and it's in bad shape but I don't know how to go about repairing it. The main issue is the bridge. The guitar was kept high strung and the bridge has twisted and lifted off slightly at the base. T…

So now put the iron on low, heat the bridge for at least 5 minutes, then take it and the insulating cardboard off, and see if you can begin to work palette knives under the bridge. If it's not relativ…

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…

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…

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…
