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…

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…

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…

So after a small battle with an illness, I started building again just today! The first (old) own design since 2020. It seem like I'm breathing again! Images

Hi Everyone, I believe this may be my first post here, so just a quick introduction — I’m Andrew in Milwaukee, WI. I’ve been building a few years. My luthier eyes were opened first by Charles Fox in Portland which led me to the Gallop School. I recently retired from a tech career and I am now based in Milwaukee, WI focusing on acoustic builds. I’m currently exploring wood-body resonator guitars, and I’d love to learn more from t…

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…

Found this, will print later, saves a little design time. https://makerworld.com/models/1835300?appSharePlatform=copy Having made 3D printed Vacuum fixtures for CNC previously, I’d recommend printing as close to 100% theoretical density as possible, as any voids can and likely will lead to suction loss. Finer dimensional stability and layer adhesion with something with Glass Fibres will probably help. I’d avoid materials with additives th…

Hi -- I am planning to have a maple Thinline Tele top painted by an automotive paint shop. They've made a glossy and a matt sample for me and it looks great. I wonder if anyone has any experience with this, and specifically: - if I bind the top first, will the paint stand very proud above the binding once I scrape the paint off the binding? - the matt looks terrific, but it looks like it will burnish and get shiny in spots or line…

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…

Hi guys, here’s something I’ve been working on: a fully automated, programmable pickup winder. The software is still in alpha testing and there’s still a lot to design, but this is what it looks like so far! Images

I'm reading the Design book of the Gilet/Gore set (2nd Edition) and ran across something that surprised me. Under "Top bracing layout - guidelines" (Section 4.4.8, pp 4-52) Gore writes, "Brace ends that are housed into the linings stiffen the edge of the soundbard considerably and so constrain its mobility. Unless you are chasing a particular effect, it is generally not very beneficial to house the lower bout braces into the linings." My…

As one does, I got distracted designing a fretboard for my newest acoustic build and thought 'Wouldn't it be great if there was a plugin to do this automatically?' Several days and 1000 lines of Python later, it's definitely possible. But then I thought "What else might be interesting as part of a plugin like this?" So I'd love to hear what you think, including: - Is this something you think is valuable (irrespective of price) - If it is va…

Hello friends - I am a bass guitar builder who is considering building a neck-through Flying V-style guitar with a 25.5" scale length and a Floyd Rose tremolo bridge. I have not built any neck-through instruments and would appreciate any guidance on where to begin with respect to laying out the design, in particular, getting the neck angle right and the headstock angled properly. Any resources are welcomed and if someone has any interes…

Hello! This is my current build! https://www.instagram.com/p/DMO6PqXRAkg/?utm_source=ig_web_copy_link&igsh=MWdhbW4wdG51bDJ4ZQ== "Here’s a quick check-in on the two guitars I’m currently working on. The bodies are getting ready for binding(arm bevel too!), while the neck is in the middle of headstock design. For the tiger-patterned guitar, I’m planning to inlay Jakho-do (Korean tiger-and-magpie painting) with mother-of-pearl. The other one…

Dear looth community/colleagues around the world, During 2023/24 I have developed a digital gauge to measure so-called longitudinal twist of (bass) guitar necks: the LTwist® gauge. Just to be clear, this is about the "cork screw" type of deviation along the length of a neck, not the bow of a neck. I think there is no need to explain how a too severe neck twist can make it difficult or even impossible to set up a stringed instrument (guita…

Hi Thought I'd say "hi". I've just joined the group. I'm Rob, I'm based in Yorkshire in North England. I'm mainly interested in elictric guitar and electric bass building and playing. I've built around 5-6 guitars/basses through 3d printing. I've two Prusa MK4's and been printing for around five years. The design and build of them is logged here https://www.basschat.co.uk/topic/485214-a-3d-printed-six-string/ And https://www.basschat.co.uk/t…
