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
