Splitting A Sound Hole Clamp In Half

I recently had a guitar come in with a crack in the top. The top was an arch top so the top was thick and the crack uneven from side to side so I wanted to be able to supply more pressure then just using magnets to be able to even up the crack sides. But access was limited to a small sound hole and so no way to get jacks or a clamp to fit. I also wanted to use full length longer cleats instead of fiddling with the tedious fishing reel…

Cool. That screw is, in fact, a bull pin. The plate is not threaded. The threads help hold the screw/pin in position (won’t wiggle/fall out) Your take is spot on and the whole idea of sharing with t…

Newbie luthier wannabe

Thought I would introduce myself, I am a retired computer nerd ex farm boy that loves to fix things… used to repair/rebuild pianos but now that I live in FL, space is at a premium in small home so I now am venturing into repairing guitars…. I have numerous practice candidates I have picked up on the cheap as not to destroy anything of value or collectability, and have tooled up with enough stuff to be dangerous. I have done several aco…

1973 Jazz Bass Refret Issues with Pulling Frets

Looking for some guidance here – I have a 1973 Jazz Bass with maple fretboard and fretboard binding in for a re-fret. The finish is of course built up thick and crackly along the frets, and although they’re not seated too nicely, the first few came out really tough and chippy even after scoring the finish really well. I’m aware that Fenders were fretted sideways until 1982, but because of the binding, pushing them out sideways is not an…

Ok perfect. I use the newer StewMac fret pullers with the slightly narrower jaws than the older type in your video you shared. Are those your preferred pullers?

Warped x-brace on Gibson L-3

I watched the Guild F-20 video (https://dev2.loothgroup.com/groups/repair-and-restoration/forum/topic/cracker-x-braces-on-guild-f20/#post-60310) with great interest since I've been working on a Gibson L-3 with a similar problem. A little back story - The original repair request was to address a small pickguard crack on the sound hole side. After peeking inside, I saw 5 loose brace ends on the treble side. Still a pretty standard repair…

That move of 3D printing the taper you want and running it through the sander to make a copy just blew my mind! Thanks for sharing Dave!

Cracked x-braces on Guild F20

Looking for some advice on a repair for a 1966 Guild F20. The guitar top is significantly depressed (bowl shaped) around the sound hole. This is due to both upper x-braces being cracked as they tuck under the purfling. Also, the bridge is starting to pull off. Any suggestions on sequence of actions? Specifically, should I try to flatten the top area above the bridge and around the sound hole prior to fixing the x-braces? Would it be…

Tony thanks for sharing this example. Your work really paid off! My top deflection is about the same (1/4" at the sound hole). It's interesting to me that you took the bridge plate off. When I reach in…

Need advice on my first repair job

I would really appreciate some advice on this repair that I need to do. I've built a number of (classical) guitars so far, but this is my first repair job. I have already set the expectations with the customer that I can probably fix it structurally but the repair will be visible. The guitar is modestly priced and of no historical significance so it seems like an ideal project to take on as a first one. The guitar suffered a blow on the…

Strange Fender neck with some problems.

Hello fellow looths! I recently had a customer come in with a '71 Fender neck that is a fusion of the 60s and 70s style. It has a veneer fretboard, no skunkstripe, 4 screwholes, 70s style tuners, 70s headstock logo, and it seems like it has a poly finish on the back of the neck, and nitro (with cracking) on the front of the headstock. Can anyone tell me if this combination is possible or could it be fake? Another thing is, even without th…

Epiphone LP Limited Edition severe fall damage

Okay gang I have a doozy of a crack repair. Young guy brought in a Epiphone LP Limited Ed. He had picked up the case while it was unlatched at the guitar took a nasty tumble. Severe finish damage, and the wood has a shear split in it as well. The undercoat is thick with a thin layer of nitro color on top. Spoke with a sweetwater rep and they said that the finish was nitro. Here's the guitar specs via Zsounds: Epiphone Inspired by Gibson…

How would you approach a neck reset where the heel has already cracked?

I have a red-label Yamaha FG-180 that’s in overall nice condition, but the neck angle is poor and the heel is already cracked. I’d like to attempt a neck reset, but I’m unsure how to proceed given the existing crack. Should I approach the reset as usual, or plan an alternate method because of the damage? Has anyone here tackled a reset on a guitar with a pre-existing heel crack? I know a crack can develop during the reset process, but I…

Hi Nathan. Here are the dovetail measurements from the FG75. Don't know if they're the same but may get you in the ballpark.

000-28 w/ neck block shift

Im going to attach some photos of a 000-style guitar from Potomac(I believe an Eastman product) that has some top cracks and deformation around the neck block from what I assume to be a shift of the neck block. How do you all approach repairs like this. Im thinking that pulling the neck and somehow pushing the block back into place from the inside is about the right course of action, but if anyone has some advice, Id appreciate it! In th…

Pulling the neck would probably be the best move for absolute bullet proofedness. Chances are high that this was put together with some kind of titebond variant and the joint between the top and the n…

Cracked Fingerboard Fill ? ('66 Jose Ramirez)

1966 Jose Ramirez 2A Flamenco with a split/cracked fingerboard. It's been cracked for years, and is in stable condition at humidity. Spans from 11/12th fret to the sound hole. I've filled smaller splits/cracks with ebony dust and superglue, or black superglue in the past, and had great results. Do any of you ever use ebony shavings to spline these? (likely need to pull frets for that) I'd love to hear how you approach these, and when you d…

I've never used ebony shavings. That's getting pretty wide, though and it's on a nice guitar, so I might try if going for best results. The main problem is the frets. Are you planning on a refret ? If…

Replacing Nylon Saddles on a Gibson SB-400 bass

I need some advice on replacing some saddles. I have been restoring a "dumpster dive" 1972 Gibson SB-400 bass, with a Multiplex bridge. It has nylon saddles, one of which has a crack. The screws upon which the saddles ride are not removable, as the end has an enlarged cap (see picture). How do I replace the saddles without destroying the screws? I repaired the cracking nylon saddle by supergluing two layers of fiberglass wrap (used for f…

71 SG Body/Neck Joint Cracks

It was only a matter of time before one of these arrived on my bench. The neck on this 71 SG Deluxe is caving through to the neck pickup cavity— In a similar fashion to what happens on old jr’s. Both sides of the cutaway have cracks that extend through to the pickup route and I can flex them easily. Problem is that the cracks are not straight and wander all over. I worry about being able to get enough glue in there because of this. Thin…

I'm not sure what that would get you other than access to more gluing surface, which aint nothing, but unless you have some whack-a-doo grain orientation, isn't why that broke in the first place. Also…

Martin D-18VM No truss rod?

In the process of evaluating the repairs needed on this guitar I checked to see if the truss rod was working. There is hole in the transverse brace where you would normally insert a truss rod, but all I see is the end of a metal bar with a smallish hole in the center. I tried several allen wrenches that would fit in the hole, but nothing seems to grab. Did they really eliminate the adjustable truss rod on this vintage reproduction? Here'…

A reproduction with that much wrong?!?! Did the thing go of a cliff in the back of a car without a seat belt, get thrown, and wash up 10 miles south?
