I still get many requests for baroque guitar plans. Builders should look at this page: www.luth.org/plans. This is a technical drawing of a baroque guitar that was measured by R.E. Brune and drawn by John Morgan. Scale length 68.8CM. This guitar may have been owned by Marie Antoinette. 5 double courses, 9 tied frets; highly vaulted back. One sheet 30" x 48". An explanatory article and reduced plan appears in Big Red Book #2. The Big Red Books, published by the Guild of American Luthiers, contain a wealth of information for builders and should be in the reference library of every luthier. Disclaimer: Even though I wrote some of these articles, I make nothing from the sale of these books. | 
Historically, many baroque guitars were decorated with ivory. I substituted American Holly (Ilex Opaca) for ivory for obvious reasons. I'm not going to explain every building step since the photos pretty much say it all.
