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…

Here is a super basic thing I just modeled and 3d printed. Small drill guides to place a 2mm hole directly centered in the side of a fretboard. I made a few sizes for different fretboard thicknesses. Seems simple but its a huge time saver.

I've seen the Elevate Luthierie jig, and it seems simple enough. One thing I don't like about their explanation video is the handwaving around "set the joint length where you want it"...feels like even with the jig, you have to do too much measuring to make it fit exactly (or within the tolerance you want) Given I can model well enough in Fusion and have a 3D printer, feels like a challenge to take on! As far as I can see, the jig is just…

This is a repost from the main feed so it is in the correct forum. The recent F5 CAD modeling video inspired me to take a stab at it. I use Fusion 360 and have already completed a full A5 model that I’m using to prepare a lot of parts for my CNC. The F5 top seems intimidating. I focused on modeling the scroll alone for now. I didn’t pay attention to following a plan, or having perfect dimensions, or getting the curves to look perfect th…

I was finally able to model something like a Gibson L7 top plate! Now I'm trying to build my f-holes... My only reference is the Benedetto archtop book, where it puts a few rules of thumb about how the f-holes should be placed. My question is, how precise are we talking here? One of the rules of thumb is that the bridge intersects at the midway point of the f-holes. Does this imply that the f-holes are at a certain location on the plate,…

Model is "The '80". Daion built some nice guitars in the 70's and 80's out of a small shop in Japan. Nice old all mahogany 12 string. It's my instrument so doing a bolt on conversion. Forget about trying to get the neck off one of these (apart from Kung Fu) - neck construction seems to be based on multiple dowels (a bit like some Japanese furniture I suppose)
