I was approached by a local music venue about finishing over the signatures on this Dean guitar. I have finished over signatures before, but never an entire guitar. The main challenges, as I see it, with this endeavor is prepping the existing finish. Cleaning the existing finish without disturbing the signatures will be time consuming enough, but abraiding/sanding the finish will be cost prohibitive. I have already experimented on a test…

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…

Hi everyone, I'm Martino from Hub of Acoustics, a collaborative project created by luthiers for luthiers. Our goal is to explore and teach acoustic principles that are directly relevant to instrument making. In 2026, we’ll be running four courses in different parts of the world, all focused on giving luthiers practical tools to better understand and control the acoustics of their instruments. We’re excited to introduce our very…

Hi all. Brand new member. I’ve been building a classical guitar via kit from LMI for a couple of years now. I keep putting it off but recently became motivated to get back to it. Unfortunately LMI is out of business so I now have no one to go to to ask questions. I’m at the stage where I’m putting the sides together in the form. I followed the dimensions for the form based on the plans as I measured them, but the sides overlap pretty ba…

Speaking of Trevor Gore... I've started using falcate bracing on my ukuleles and in making the braces, 3 strips of .0625" spruce are bent and then put in a bent lamination glue up rig using epoxy. Bending spruce is no fun on a hot pipe. It's slow, fussy, the fibers want to delaminate. I have been thinking about building a small dedicated steam box. Pulling all 3 of the strips out at once and bending them over a form with a metal back…

For my current mandolin build, I set out to answer 2 questions: 1. Whether to use physical deflection or frequency analysis to measure stiffness, and 2. How well can I measure wood quality in rough sawn form? (T. Gore says it needs to be planed smooth and rectangular for frequency analysis.) I have 4 different topwood species available for my current build: California Sitka, Englemann, Lutz, and Coastal Redwood. The billets range from 37…

hello looths - i'm building my first guitar. generally following (and enjoying) the gore/gilet books. after 3 tries, i've yet to get a crack free bend around the nose of a venetian cutaway with a mahogany side. i made a version of the fox bender - using clamps on hand for the waist and cutaway, and a pid temp controller (verified accuracy), and am using a stew mac blanket and three straps. the recipe for my last attempt was: sapelle (fo…

A client has asked me to build an acoustic guitar using crelicam ebony for the back and sides that he is getting form Stewmac. I have heard it's challenging to bend, and this will be an OM so the waist is pretty tight. Any thoughts or suggestions for bending these sides? I use a homemade bending machine modelled after LMI's latest design (may they rest in peace) and I have had good success bending rosewood, walnut, mahogany, and pau fer…
