OG Proper's Relief Gauge Parts

Hey folks! I picked up a neck relief gauge from Doug in one of the earlier batches, maybe the introductory run? Some of the small feet caps that thread onto the moving legs of the tool have cracked, broken, or become worn down. I contacted StewMac about purchasing replacement parts, but they don't sell subparts for the relief gauge and otherwise won't help me. They appear 3D printed, so I was wondering if anyone with the means to print s…

“I live my life a 1/8 mm at a time”

Guitar neck topology is worth going microscopic. 🔬🦠 After building my starting surface from a wireframe network in the sketch environment; a system of 4-degree control point spline rails, tangent to projected isoparametric curves along the shaft — I can convert the NURBS surface to a T-Spline and start cleaning up the artifacts left behind by the original loft. In this demo I’m turning on Box Display, which feels strange at first because…

Acrylic Centering Guide For Obrien Neck Jig?

Does anyone have a laser cutter/engraver file for the Acrylic centerline guide for the O'Brien Neck Jig? I can't find any replacement parts and was hoping to simply make my own. Its the most susceptible piece on the jig and my students can be rough on those.

He's working with Stewmac to produce those. I'm not sure when they are dropping, but it's in the works.

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…

Getting perfectly flat without a jointer

Hello -- I am trying to joint a Tele-style mahogany neck blank. I have a Metabo planer in good condition, but no jointer. I secured the c. 40 mm thick blank to a flat plywood sled and shimmed it well. It's hot-glued in place, and absolutely no rocking from any corner or edge. But as I plane it down, I still have about 1 mm difference from one end of the blank to the other when I put a straightedge on the surface (see photo, with backlig…

I feel this is a big missing element in my workshop (for guitar making at least). But where I live all tools, and especially machines, are a good 2x the price in the US or UK. So I have to think long…

3D scanner

Anyone use a 3D scanner to make models for printing, or CNC? I've noticed a number of inexpensive scanners on the market that appear to be an able to scan with fine detail and accuracy. I've wondered if they could be used to scan a guitar neck, or arch top mandolin plate to then cut on a CNC after tweaking in a CAD program.

That's kind of what I thought. The scan comes out dirty and needs more manipulation in software which can be more work than drawing it in the first place. I was curious as there are now numerous ads…

One thing you might try is changing the orientation to have it on the side. You might print it as a block of 5 so it self supports and then split after. I bet @member might…
