Posted on August 11, 2021March 5, 2024 by Dale Phillips Neck Relief Neck Relief by Philip Mayes Originally published in Guild of American Luthiers Data Sheet #124, 1979 and Lutherie Woods and Steel String Guitars, 1998 A spate of repairs involving fret buzzing set me thinking about the ideal neck shape. Some people like a flat fingerboard. Lots of people advocate a neck that’s straight at the body and lifts slightly towards the head, as seen in Fig. 1. Some people vote for a tapering away at the end of the fingerboard, as in Fig. 2. The reason for all this, of course, is to accommodate the shape of a plucked string, diagramed in Fig. 3.

Posted on August 11, 2021March 5, 2024 by Dale Phillips Violin Varnish and Sealers Violin Varnish and Sealers by Graham Caldersmith Originally published as Guild of American Luthiers Data Sheet #276, 1984, and Big Red Book of American Luthierie Volume One, 2000 Probably more unsubstantiated speculation has been written about violin varnish, its effects on the instrument, and the quest for the “lost” Cremonese recipe than about any other of the subtleties of the violin and its behavior. It is true that those who have examined enough violins to appreciate the variety of varnishing systems employed by different makers in different ages cannot but admire the clear golden-brown varnish sometimes grading to a deep red that characterizes 17th–18th century Cremonese instruments. It is also true that varnish preparation and application techniques changed to more durable and convenient ones towards the end of the 18th century when faster drying oil and spirit varnishes were developed to meet the needs of the growing furniture trade, arguably at the expense of transparency and lucidity. So while bearing in mind that the early Cremonese varnishes were not unique to the violin trade, since they appear on fine furniture and wooden ornaments of the same period, we may reasonably inquire as to how important the varnishing techniques used by the Cremonese Masters were to the excellence of the violins they produced. Were the advantages of Cremonese varnishing merely passive, in that they preserved good violins into sublime maturity, or were they also active, conditioning the wood for optimal acoustical behavior?

Posted on August 11, 2021March 5, 2024 by Dale Phillips Tinting Lacquer Marks Inlays Tinting Lacquer Marks Inlays by Michael Dresdner Originally published as Guild of American Luthiers Data Sheet #280, 1984 and Lutherie Wood and Steel String Guitars, 1998 When I have very intricate inlays and I don’t want to scribe the fingerboard, I take all the inlays and spray their backs with a rubber-type spray adhesive like photo mount. Then I place them on the fingerboard where I want them and spray it lightly with lacquer toner in a contrasting color. For instance, if the fingerboard is rosewood, I’ll spray it with bright yellow. I then pull up the inlays leaving the bright yellow lacquer and a brown spot in the shape of each inlay. It’s a great fast trick. The whole fingerboard can be done at once without any scribing.

Posted on August 11, 2021March 5, 2024 by Dale Phillips Lute Rib-Cutting Jig Lute Rib-Cutting Jig by Robert Cooper from his 1984 GAL Convention lecture Originally published in American Lutherie #4, 1985 and Big Red Book of American Lutherie Volume One, 2000 The lute I brought with me today has a half-round cross section. In such an instrument, each stave is identical in size and shape to its neighbor. A set of these ribs can be cut quite efficiently on a jig I made for use with a router fitted with a small circular saw blade. The main section of the jig is a solid wedge of wood, like a slice of apple. Or more like a slice of a pear.

Posted on August 11, 2021March 5, 2024 by Dale Phillips Ren-Shaped Precision Mold Material Ren-Shaped Precision Mold Material by Ed Beylerian Originally published in American Lutherie #21, 1990 The demand for ever-increasing quality in end-use products has generated a concurrent need for improved modeling materials. Patterns and molds constructed from traditional materials such as laminated wood and plaster cannot maintain the precise tolerances required by model makers in the automotive, aerospace, foundry, and prototyping industries. With Ren-Shape 450, models can be built with a more stable medium, using precision numerically controlled (NC) machining equipment. I obtained a 2"×16"×60" board of Ren-Shape from Ciba-Geigy corporation, as well as the laminating compound and the repair kit. Ren-Shape is about the same hardness and density of a medium hard wood, and a tan color. The setting time of the two-part laminating compound is easily controlled by the amount of hardener used, and can range from one to six hours. The repair compound sets overnight.
