Acoustic Guitar Form Inserts

General Information:

One of the first and most important steps a luthier should complete is an accurate set of guitar forms for each guitar shape that is intend to build. Our 3D CNC files for each Acoustic Guitar Form Insert are designed directly from the 2D files of our design drawings, assuring you of their accuracy.

Form files will be available for each guitar shape series that we offer. Note that many guitar shapes are shared with several guitar plans. For instance the Dreadnought Form Insert will work with (5) Different Guitar Plans.

If an instrument has a option for a Venetian Style cutaway shown on the plan drawings, the cutaway version will be included in the 3D CNC file for that particular instrument. Please note that Florentine Cutaways are not included in these files as you would use the standard shape form insert and then use our Florentine Cutaway Bender to for thje wood for this cutaway.
