Neck block for adjustable neck -thoughts on design

I've built a number of classical guitars with an adjustable neck and they seem to gather quite a bit of interest, so i'm currently in the process of looking to refine the design and build. It's quite a simple construction where the neck is held together by string tension and hangs on a pivot. I developed a 3d printed "socket" which acts as the interface between the body and the guitar and allows for some fine tuning of the alignment of t…

Not really answering your question but I've done a version of the Smallman/Gore joint (I think it's really just Smallman but whatever) on all my guitars (nylon/steel/gypsy). I'm not particularly conc…

neck reset acoustic guitar with two necks (harp guitar)

I've owned this Jersey City made 12-string/drone 'harp' guitar for a few years and want to get on the repair. I've taken the necks off many dozens of Schmidt-made guitars but never one with two necks. I've searched the web looking for harp guitar neck removal and didn't find anything of use. Asking for any tips/aids/experience from the loothers. My plan is to make a custom neck removal jig that fits the necks, and then drill the typical…

Beautiful guitar. Will your neck jig(s) bind the two necks together top and bottom, as well as push up equally on the heels while you release the joints? Seems like any loss of rigid coupling between…

Looking for CAD expert

Hello all! My name is Jake and I run a repair shop out of my NYC apartment. I am looking for someone who's experienced in CAD to help me with a project.

1930s Martin 00: Best practice

Long story short, customer want to add carbon fiber in the neck for strength. Without string tension, the neck is dead straight; with strings, it's about double the relief he'd like. Is it insane to add carbon to this guitar? Or is it fine?

Hey Keith! That's a bit of a tough question to answer without having more details, but I'll take a swing at it. If, as you said, the neck is dead straight without strings and has double the relief he…

PBass has been stripped of it finish… looking for expertise, friends!

Hi friends, I just stumbled upon a 1966 P-Bass, nearly completely original. The owner bought it in 1971 and it had already been stripped of its original finish. That was a thing back then. You can guess that 55 years of gigging had the wood absorb much of the owner’s DNA and sweat. Maybe a few beers as well. Surface was quite tacky as you can expect. I cleaned it with naphta and StewMac’c brand-new cleaner (quite a great product I'd say…

Ill chime in. Go with shellac first. It may be all you need and if you decide to go with something else, youve already applied the universal seal coat. Also, it has the best chance of sticking to any…

Appraisals

Friend brought his "old guitar in the basement" over for me to have a look at. Long story short, it's a 1945 D-18, it's all original and it's a beauty. He had no idea. I explained to him that it was worth somewhere between 15 and 25 thousand bucks, that it needed some fairly routine repairs and that he should get - among other things - an insurance rider and take a little more care of the guitar than he has been. Picture attached for fu…

The VG price guide is a pretty good place to start. On something like that, I'd be tempted to pay for an appraisal from Gruhn's though. They used to do email appraisals that were reasonably priced. Re…

Bass Neck Stiffness, Can't Get Enough Relief

Hello, I hope everyone is having a great 4th of July weekend so far. I was recently asked by a friend to work on a cheap S101 bass someone had given to him. It had no electronics and it was severally back bowed. After finishing up the electronics, I did the set up. He wanted the guitar tuned low, to Drop C. So, I went out and bought some Ernie Ball Power Slinkies 55-110. Once I got to the nut depth check, it was clear there were large, g…

Experienced Builder and Red Wing Grad

Howdy folks, I'm a 2026 graduate of the two year guitar program at Red Wing (Minnesota State College Southeast).

I also spent a couple months in the finishing department level sanding and pore filling ~300…

Mandocello neck block

I am building an archtop mandocello (A style) and I'm trying to find out how to make the neck block. It would be more or less like an A style mandolin neck block, but obviously quite a lot bigger. More or less like the image attached. The blank should be aprox 10 x 8 x 12 cm. I'm trying to find a piece of hardwood big enough for this, would it be acceptable if I made some kind of laminated piece? And how should the grain direction be idea…

The traditional A style mandocello neckblocks were mahogany. There are some really good reasons for laminating them because there are forces on the block that make any single grain orientation a damne…

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…
