Is an online course for guitar repair a good way to go?
Hi all. I've just joined the group....I'm pretty certain what I'm asking here has already been covered somewhere but not really sure at the moment how to search chat topics. If so, and it's easier to just point me to an older chat...please do so! I'm in my 50s, been playing guitar for as long as I can remember. I'm a trained wood-worker (amongst other things) and am looking to start a new journey into guitar repairs. At my age I can't a…
My favorite repair tool- NEW VIDEO
Tacform Update
I’ve been speed modelling parts with the printer running 24/7 since inception. There are currently somewhere around 75-100 individual pieces modelled in my source file. Mostly only building on what I’m considering the X axis, but it’s Freeform so I’ve used them to build out Y.. anyways… Connectors, Extenders, Couplers, Links, Sleeves, Feets, Plugs, Panels, Hooks… and on and on. In a moments time, I will have a mass drop folder of Standar…

Fast & Curious 3: Parametric Drift
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.

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…
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…
Widening fretslots
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…
Mossman Guitar trussrod tool
I know some of you pros that have been doing repairs for years must have a tool.....Anyone have any suggestions for a trussrod tool to adjust a mossman? or photos of something i can make on the fly? I have tried shaving down a socket but no luck the brace inside leaves little to no clearance.
Custom Headless neck for Ibanez 7 string
Hey Loothers, A client reached out requesting a neck with wider nut for his headless Ibanez 7 string. He would like it built with rosewood for the neck and the fret board which has been stored for years at a consistent 45 to 50 % humidity in his home. The frets are angled to make it play more ergonomically but it is not a multi scale instrument. He plays finger picking fusion style and simply needs more neck width at the nut to play mu…
The first tool to measure longitudinal neck torsion/twist - the LTwist® gauge
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…
What touring tech topics would interest you looths?
Hello all, new member here. I've been working as a touring tech for 20 years and just noticed this section of the forum was empty, so I figured I'd give it a kick. Are there any topics\questions\ideas\etc that people would be interested in hearing about or discussing from a touring perspective? If so, drop a comment here and I'll see if I can address it or post any relevant photos\content. I'm leaving Wednesday for a month in Europe fol…
Cutting circles with CNC
Should a CNC be able to cut a perfect looking circle? I'm trying to make solid wood rosette rings. I made the tool path a profile cut. The top and bottom of both Y positions come out uneven in width than the rest of the ring. I've tried slowing down the feed and plunge rate, but it doesn't seem to make any difference. I have an old second generation Nextwave CNC shark and use Aspire for CAD and CAM. Linear cuts seem to be accurat…
Please share your processes for cracks that need splints
Hello good people, My shop’s in Quebec City, so I get to repair an ungodly amount of cracks thanks to our brutal winter and customers being largely unaware of the requirements of maintaining proper RH. Now for the first time (call me lucky) I have two very good guitars in the shop whose cracks won't close up after having been rehumidified for a few weeks. I have tried over-humidifying and it does it, but once returned to proper RH (50%)…
