The Hub

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…

Great Tool. Great Benchy. Testing Threads, Sliding Dovetails, Overhangs, and it’s actually useful instead of that boat.. so testing wear resistance too. igus iglidur I151 Thanks for the model @member

I did a pretty big update to my web tools last week. These are updated from the older versions I had up on celestialinstruments.com. There’s an updated FFT tool now, plus mode detection for guitars and plates, wolf note detection, played-note energy transfer, monopole mobility, plate thickness calculation, and 1/2/3/4 DOF modeling that can be prefilled from FFT data. The part I’m most excited about is being able to fit a measured guitar re…

https://www.instagram.com/reel/DWAuW40jAR_/?igsh=MW1jNDdoYzllMGFmMA== I’ve spent a few overly caffeinated days bouncing between modelling environments, different combinations of operations, tools.. subtle differences in how the coffee is brewed. In short… • Building Iso Curves in Sketch. Defining the surface structure and flow • NURBS Surfacing from curves, smooth intentional surface topology. • BRep Face to T-Spline in Form Environment.

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…

Hello estimable friends, A very long-term friend of mine left us on Christmas Eve after a long illness. His sister tasked me with evaluating, restoring, and selling his stuff. Today I'm preparing to restore a 2008 Longhorn GOM to its original EMGs. Pulling out the humbuckers I see a Pearly Gates and… what looks like an original short-magnet PAF. Correct shape brass screws for the bobbins, UV light confirms sticker and tape, tooling mark…

Hi everyone - I recently ran into trouble making new nut for one of my necks that needed to be trued and re-fretted. I roughed in the nut as usual and then, with the bass guitar fully assembled and strung up, I started cutting the slots to depth. I use the StewMac digital nut slot depth gauge and have had good results in the past. I marked the nut's lowest points (radiused) using the guitar nut scribe tool (first time using this!) and c…

It's that time of the year when I start to get all paranoid on the humidity levels of my shop. It happens at this time as the heating seems to send my hygrometers out of whack and it's quite difficult to keep things stable. So far i've been relying on keeping a 45% constant humidity in an automated system I built on Domoticz (similar to Home Assistant), which control a humidifier and dehumidifier. I'm not that confident i got this nailed…

Hello. I am interested in the luthiers opinions about using Osmo oil as a finish on acoustic guitars? Advantages vs disadvantages. I am a new builder with small home workshop, mostly using hand tools to build my first acoustic guitar, an OM pre war style. Thank you all.

Santa heard I had a challenging year so he got me a 3d printer for Christmas. I’ve been printing like crazy, learning the machine. This has resulted in a bunch of tools that either don’t work for me, were attempts at mixing colors, or have very minor printing blemishes. Two lots up for grabs to anyone in the US who wants either. I’ll mail to you for free. First one to claim each gets it :) First lot has parametric nut and saddle sanders…

One of the first things I made with my 3D printer was this small sanding block with a ball handle that fits my palm. I was inspired by the little L-N squirrel tail block plane that my father gave me. I have neuropathy in my fingers, on top of arthritis, and it's uncomfortable for me to hold the little blocks of wood that I used before. I was surprised how well this works, and these two tools are always within arm's reach.

I am not selling these, Gregg Johnson has asked for them to be posted. $325 shipped - Email [email withheld]

I am looking for new ideas on tools or methods for cleaning under partially loose braces to insure a good glue joint. In the past I've tried flossing with sandpaper, using the metal cutting edge from a wax paper box, maybe some extra thin files. In this job, one of the loose braces is up against the bridge plate, so it's impossible to pass something all the way through. The loose parts are marked with the red ellipses.

Thought I would introduce myself, I am a retired computer nerd ex farm boy that loves to fix things… used to repair/rebuild pianos but now that I live in FL, space is at a premium in small home so I now am venturing into repairing guitars…. I have numerous practice candidates I have picked up on the cheap as not to destroy anything of value or collectability, and have tooled up with enough stuff to be dangerous. I have done several aco…

Hello everyone, I use a Stewmac japanese fretsaw (which produces .023" wide fretslots, matching the width of the tang of stewmac wire) to recut my slots on refrets. The saw does a good job making the slots deeper, but struggles to make them wider and binds like crazy throughout the process. I think that is due to it not having enough (or any) set, so in theory it only cut downwards and does a poor job removing material from the slot wall…
