Mandolin acoustics academy - Hub Of Acoustics

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…

FFT tools for modal frequency work

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…

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.

Brett -- If you are doing free-form modelling, have you tried using Shapr3D software? I just started playing around with it and it seems to be reasonably intuitive and easy with which to get started.…

Help needed identifying real PAF

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…

Lindy Fralin quickly pointed to me that the pickup looks authentic all right, but the magnet is non-original. Having a second look at it myself, I realized very fast that it has been changed as it is…

Nut slot and action trouble

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…

That's actually not how that tool was intended to be used. That is essentially plotting a like to the top of the fret. With a bass, you would need much more than that. When James and I came up with th…

Humidity stability, moisture meters

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…

Thanks both for your replies. In all honesty so far I have not had any issues with my builds. The Trevor Gore books do mention that gluing should always be done at 45%RH, so i'll keep trying to stick t…
