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…

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…

Guitar neck topology is worth going microscopic. 🔬🦠 After building my starting surface from a wireframe network in the sketch environment; a system of 4-degree control point spline rails, tangent to projected isoparametric curves along the shaft — I can convert the NURBS surface to a T-Spline and start cleaning up the artifacts left behind by the original loft. In this demo I’m turning on Box Display, which feels strange at first because…

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…

Back at tinkering with the new Isoparametric Curve tool in Fusion. Scroll down to PICTURES LETS GO! If you want to skip this little walk through Autodesk Fusion memory lane, clearing up some of the UI conFusion. Why something so seemingly basic, is just being added today. 2009- Autodesk Inventor, hybrid modelling experiment, parametric and direct CAD in one hybrid system. 2011- Autodesk acquires T Splines Inc. an organic modeller still in…

I had a feeling I should have updated Fusion before 3D Club... Todays New update introduced Project Isoparametric Curves "Isoparametric curves in the Sketch environment, adding new ways to extract surface U and V curves for more controlled lofts, rails, and surface transitions" ...The meridians on the shaft surface seen in the attached photo. I still haven't fully grasped how to align these between faces, attached is a quick…

I’m curious to hear from everyone in the trenches, how they manage repairs they really don’t want to do. At this point I am offering customer work again to a small group of people who know me and have worked with me over the years. I’ve had a few people email that I don’t know, being a little pushy wanting to know price and turnaround time because “I need this by the xxth of the month”. I’ve simply offered them a referral to another sh…

Hey all - I've got a couple Gibson headstock repair investments that I'd like to practice inserting splines for reinforcement (or I may go the backstrap method..tbd). Do you have any jig recommendations or preferences? I've only seen the G&W option (which looks awesome), several ebay knock-offs and lots of DIY jigs. I welcome your feedback. Thanks and all the best, Chris

Hey guys, Up until now I've always tried to blend any repairs into the surrounding area when it comes to finishing and avoid refinishing as much as possible. However, im yet to be fully satisfied with the results or hit the elusive "invisible repair" So my question is, for this headstock fix in the image, would you simplly refinish over the splines or consider refinishing the whole neck to avoid the blending battle? For what its worth, its…

The previously glued scroll on a mandolin headstock has broken off again. I've seen Frank Ford's fix, where he routs and glues in a spline, but I am wondering if there is a simpler fix for a less expensive instrument. Thanks.

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…

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…

Hey! So I've got a customer who has dropped off with me one of the nastier headstock breaks I've seen in recent memory. There is excess glue of some sort (rock hard, clear) all inside the break, along with the threaded tracks of the screws. I'd usually just recommend a replacement neck in this case, but the customer is desperate to keep this neck as it holds some sentimental value to him. He's aware the repair will not be invisible, how…

Has anyone ever used the belt-sander spline process for a headstock repair? It’s when you glue up the headstock then push it up against the rounded edge of a belt sander to remove a rounded chunk of wood, then patching the chunk by sanding down a rounded spline to fit it. Seems much easier than routing channels because you can put sticky sandpaper directly on the sanded-portion of the headstock/neck and shape the spline perfectly to the…

I have a Gibson Chet Atkins in the shop with a nasty headstock re-break. The headstock was broken off previously and repaired (at another shop). The repair to the front of the headstock has held, but the main break opened back up along the same line. Since the headstock is hanging on by the headstock veneer I can't really open up the crack enough to clean out the old glue residue that's deep inside the break. I'm looking for advise as t…

I have 1988 Gibson ES-335 with a broken headstock. It was poorly glued before and is broken again. I can't get the broken faces of the wood to close up due to the mess of glue or whatever is in there. The headstock overlay is the only thing holding it together. I have a couple of questions: - Any idea what glue was used to attach the headstock overlay? Is it easy to remove cleanly? I'd like to at least loosen the part of it on the neck…
