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…

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. I am working on a 5 string headless bass build for a customer. The neck & body are to be CNCed by a local mill here in Brooklyn, NY. I have a 2D design (PDF and CRD), but I need help making some modifications, as well as translating it to 3D. Pay is negotiable. I will basically pay whate…

Sadowsky use unique control plate screws which are much smaller than common plate screws. I believe the ones they use are: #3 × 3/8" Phillips Pan(domed) Head Black Oxide csk self tapping Sheet Metal Screw Type AB thread. Being in the UK, these are really hard to find, pretty much don’t exist here, so can anyone please help me or point me in the direction of a supplier? I’ve contacted Sadowsky direct with no response and also many of my main…

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…

Dialled in the Beta, much further. Now at v1.1.0 Echoing Christopher Alexander’s argument in the first half of “Notes on the Synthesis of Form” here. Parametric, Semi-Lattice Structures. Centres within Centres, interacting to form the whole. A living structure. Because of the dimension of time, and feature hierarchy, and methodology we end up with a Centre Oriented Semi-lattice Hyper-graph, or COSH for short. This will be available on the…

Rask Guitars — Utah (relocation required) Rask Guitars is a Utah-based custom shop dedicated to building exceptional instruments — primarily high-end acoustics, alongside electric guitars and prototypes. We operate with a small, focused team where craftsmanship isn't just a standard, it's the entire point. We're growing, and we're looking for a skilled, experienced luthier who's ready to plug into a real production environment, contribute…

A visual dependency map for Autodesk Fusion. It turns complex Fusion designs into an interactive map of model logic, helping users understand how parameters, sketches, construction references, features, bodies, and other design elements relate to each other. Instead of digging through dense timelines, browser trees, and feature chains, Node Atlas gives users a readable graph of how a design is connected. It is built for designers, builder…

Modified Feed Spool to have two sandpaper slots: one for 400 grit or lower and one for 600 grit or higher. Modified Take Up Spool slots to hold 600 grit and higher papers without slipping. Updated files are available in .zip download. https://dev2.loothgroup.com/loothprint/fretsander/ Images

Doug Proper designed a sanding jig that supports variable concave and convex curves, described in the following Loothgroup article: https://loothgroup.com/post-imgcap/the-variable-radius-sander/ I built one and am impressed with how it facilitates preparing bridges, braces and also allows tracing any radius using the chord formula. I made a rough measured drawing and assembly guide to share, with Doug's blessing. First step, ma…

Hey Everyone! I have been messing around with a program that Ian introduced me to called "FarPlay". It is similar to zoom but designed for playing music together. In prototyping it I have made some discoveries, particularly that you need a really solid internet connection. Wifi seems doable but causes the most problems. If enough people were interested I am imagining two different ways it could be fun for us. The first would be…

I had a vintage Gretsch semi hollow come through the shop this week and it's left me with some questions. First off identifying the instrument's model has been a trick so far. The only information I can find is that is was likely built in and around the early 50's Second, it's in need of a neck reset. I'm not particularly well versed in resets for hollow and semi hollow guitars, especially one of this age and design. I'm very curious…
