Proper Work Station Additions

Hey all, I have been working with the work station for a few months now. I love it. I found a few little things that have helped me. 1. A mic stand to support the main beam. I bought the Total Vise version and it didn't work as well. 2. Rockler Bench Cookies as rear cross member supports. They have the correct 5/16-18 inserts in them and screw on easily. Now the thread rod has a sort of hi/low setting by just flipping it for acoustic or…

Excellent ideas. I use a cymbal stand instead of a mic stand for mine. Yes buy the neck support I agree. Can you post the link to the thumbwheels from Amazon?

Sad Old '71 Hagstrom Swede

Greetings Wise Elders and fellow seekers of the Looth Group! I hope you're all keeping well. I humbly beseech thee for thine sage wisdom and experience. I purchased a 1971 Hagstrom Swede. This guitar was basically put in a case and then forgotten about for a few decades. I felt sorry for the old man and have taken it in as a stray / project. I would like to get it playing again. There are many scars on this guitar, I have looked for as…

74 Les Paul Broken Headstock

Guitar fell straight down on the headstock when it was hanging up at the refinishers. Shit really does happen! Grain is pretty much shattered around the adjustment nut. Thinking I’ll replace the entire broken area with a completely new piece of mahogany. Scarf it in between the volute and 3rd fret. Probably even a 3 piece lamination to mimic the neck. This one was not the clients fault so the expectations for looking close to original a…

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…

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…

Tremolo issues. Not returning to "zero"

Hey guys. I guess this is an old topic, everyone talks about it but I haven't been able to find a definitive solution for this. Here's the deal: I'm working on a PRS Silversky that has this old problem that when you use the trem bar, one string (G in this case) goes sharp. I made a few adjustments to the nut as we all know that's the first thing to look at...no good. This guitar is new so I'm pretty much ruling out the bridge and posts si…

Fender, Schmender

Since most of us fix or make guitars, we have probably heard something about the cease and desist letters Fender has sent out concerning the Stratocaster. I thought I would offer some thoughts. As always, caveat emptor. There are three basic ways to protect intellectual property under Federal law. Patent, trademark, and copyright. Each protects different things, and has different underlying legal theories. Lets begin with pate…

Les Paul Truss Rod Spacer and Nut

I have a 2024 Les paul in fine shape. One thing i’m curious about is that the nut and truss rod spacer appear to have been modified but there are no finish marks in the cavity to suggest a repair. is this a normal factory install adjustment and have other folks here come across it in les pauls?

Tips for weekly maintenance on acoustics/electrics/basses?

Hey everyone, I'm a technician at a music production school in London. As the most 'guitariest' technician on staff, I've become the de facto guitar maintenance person. A big part of my work is taking a look at each guitar once a week. Usually my "routine" is to check action and intonation, making adjustments if needed, then cleaning/polishing. The thing I struggle with the most is getting strings feeling good. We use D'Addario…

Open string sitar buzz after nut slot work

Hi all, new to nut slot work world, please can you help me with this mystery? fret levelling, neck relief and string action adjustment all completed to Fender 9.5" radius spec. very happy with that. the next step: 0.011” High E string’s nut slot was a bit low. I used Dave Johnson’s (MI Guitar Craft Academy) “q-tip slot raising method”: the pulled cotton strand, plus extra thin CA glue, to fill the slot, then trim it off once dry,…

Do I need a refret?

Hi, thanks for this great resource. This is my first post here. I work on my own instruments and have little experience with advanced repairs. Recently I acquired a ca. 78 Sigma DR28H. I bought it because it sounded great and came with a pickup installed. I wanted something for open mics and gigging. With light strumming it sounded fine but I found some buzzing when I took it to a jam. I made a nut and saddle , adjusted the truss…

Harmony H167 Neck Reset...

Hey everyone, recently I've been getting more requests for neck resets from customers, and up until this point I haven't been offering them since I don't have the practical experience. I'm keen to change this, and I've borrowed my fathers Harmony H167 that has seen better days. I've done an initial cleaning and assessment, the truss rod works although I may need to force it into a backbow to have a fully adjustable neck. This shouldn't…

Also you have to take into account how much flex the top has. If you could set the neck dry then clamp it and string it up you can start the calculations about how much you to take off of the heal. In…

1964 jazz bass calamity

Any suggestions if this can be saved? It is a neck I received for free upon replacing it for a customer. The wood was missing and the rod is missing the adjusting nut. The truss rod had pushed the inlay out as well as the wood damage . I wasn't sure if it could be a structurally sound repair. I have no idea of the neck rigidity or action with strings. I wont be online because of a previous dr. appointment but I figured it would be a go…

GoBar deck adjustment

Hi folks, I thought you might be interested in this approach to having easy height adjustment for a GoBar deck. I learned this tip from my buddy, Don Parker. He lurks around here too from time to time. :) The basic idea is rather than having a booster platform on the base for use when gluing braces to plates you bring the roof down lower. There is a 3D printed spacer in black in the pics. I linked to a downloadable STL and 3MF of…

Just FYI, as far as I know, go bars have the same clamping strength no matter how much they are bent. If you want a different level of force, you need a heavier go bar. Or vice versa.

1975 Yamaha FG200J Neck Reset

Before I hack into the Yamaha, I would like to get the opinion of the experts on a method of steaming the upper end of the guitar and ‘pressing’ the neck down to adjust the angle back to factory. There are several you-tubers that have tried and recommend it. My novice intuition is that even though it may work, wont the steaming of other areas of the body such as upper braces, etc, end up weakening the construction (glue stability) to…

Newbie question on 12 string action

I recently picked up a Sterling Atlas 12 string that is in excellent shape except for some bellying, which once I get into setting action, may determine if I need to add a ‘bridge doctor’ to remediate some of it. However, I noticed that the saddle (adjustable but set to lowest point) has no curvature and there is not much down pressure on the center sets of strings which is causing some buzzing. My question is this (my first 12 string p…

Frustrating Fret buzz

when setting up acoustic guitars, from time to time I have a lot of trouble with getting the G string to ring true when fretted. Starting from lower frets and at its worst at about the 5/6th fret, the G string buzzes when plucked "heavily" (when no other string does so)...most recently a Taylor 724 which had a neck adjustment to reduce action (to 5/64-4/64), relief about 0.003 or 0.004. Increasing relief to about 8-9 helps somewhat.…

Depends on what you are calling a "buzz." The G3 at 196 Hz is going to be very near the T(1,1)2 main top resonance of the guitar. Notes fretted up higher on the G string could conceivably be near th…
