Using white or dark celluloid pieces, press out or punch out as many as you need, with a rotating leather punch. They cost about seven bucks, but they will pay for themselves in no time. If you are looking for ivory micarta for nuts and saddles etc. check the local knife makers shop. They usually carry it in big chunks, or smaller slabs, and it is not all that expensive. Besides you many have saved an elephant! In looking for a suitable material for reinforcing inside cracks, I found a product called “trigger” in a cloth store. It is a fabric closely woven, takes glue easily, and shrinks a little when dry, so as to really provide a tight repair. ◆
Posted on July 8, 2024May 14, 2025 by Dale Phillips Heat Pressing Heat Pressing by Leo Bidne Originally published as Guild of American Luthiers Data Sheet #43, 1977 Heat pressing is the art of forming wood to a new and permanent shape with heat and pressure. With practice, it is an effective method of action adjustment when extreme measures are necessary; when time or poor construction methods develop a problem, has a fair idea of what a “good” action is, and is familiar with such terms as “action”, “buzzing”, “truss rod”, and the numbering system of frets, etc. The term “buzzing” assumes that the string is plucked moderately hard. Applied to guitars, the art of heat pressing is to create the optimum neck shape for a fretted, plucked string. This means a buzz-free, even action over the entire length of the fretboard. Part One explains what that neck shape is, clears up some of the fallacies and old wives’ tales on the subject, and points out some common neck problems. The Bow Basically, a plucked string travels in a bow, like this: Become A Member to Continue Reading This Article This article is part of the Articles Online featured on our website for Guild members.

We inlaid the tortoise shell pickguards, the rosewood headstocks, ebony fingerboards, and all edgebinding. I photographed many steps in this process, and we can look at these as examples. Here’s a picture of where I’m going to cut the pearl and do the inlay work (Photo 1). I have taken an extra liberty with our cutting board, drilling a series of holes in the back where I can stand all the little Dremel attachments that I’m going to need. When we cut pearl, it is either filed, or ground with the Dremel to an exacting contour after we saw it. It gives you a much better looking job if you touch up the sawn edges of the pieces before you put them in.

Posted on July 8, 2024May 9, 2025 by Dale Phillips Repairing the Sitar Repairing the Sitar by Dave Schneider Originally published in American Lutherie #11, 1987 and Big Red Book of American Lutherie Volume One, 2000 The sitar is a member of the plucked lute family of Indian instruments known generally as vina. The name sitar is from a Persian word meaning “three strings.” The first sitars had three strings which gradually increased to seven. Sympathetic (taraf) strings were added later. The modern sitar has from eleven to thirteen sympathetic strings. An upper resonating gourd, usually attached underneath the nut, is common on most sitars today. The standard number of frets is 19, although Ravi Shankar has added a 20th fret at the top of the sitar for increased virtuosity. Teak is the wood most often used to construct sitars. The bridges for the main strings and taraf strings, which produce the characteristic buzzing sound of the sitar known as jawari, are made from bone and teak.

Posted on July 7, 2024May 15, 2025 by Dale Phillips Questions: Martin Finish Questions: Martin finish by Walter Carter Originally published in American Lutherie #104, 2010 Kerry Char from Portland, Oregon asks: Exactly what kind of finish were Gibson and Martin using before they switched to nitrocellulose lacquer? How was it applied, and when was the switch. I’m thinking that it was oil varnish similar to violin varnish, because it is resistant to acetone. But if that’s the case, how did Gibson do some of their sunbursts? I know that the earlier ones were rubbed, but later ones from the ’20s and ’30s look sprayed. Walter Carter from Nashville, Tennessee replies: Neither Gibson nor Martin made an across-the-line change from varnish to lacquer. Richard Johnston and Dick Boak note in their recent book, Martin Guitars: A Technical Reference, that Martin finishes were French polish (shellac) until 1918, when they began experimenting with different combinations of varnish and lacquer. Martin first used nitrocellulose lacquer in 1926, and by 1929 it was the standard finish on most Martin guitars.
