Posted on August 1, 2022May 22, 2025 by Dale Phillips Product Reviews: Knilling Perfection Planetary Pegs Product Reviews: Knilling Perfection Planetary Pegs Reviewed by Randy DeBey Originally published in American Lutherie #100, 2009 By now, just about everyone who works with stringed instruments has at least heard of Pegheds or Knilling Perfection Planetary Pegs. These are geared tuning pegs that look very much like ordinary ebony friction pegs, but work more like fine tuners. They contain a set of planetary gears, which reduce the rotation by a rate of 4:1 for violin family instruments and flamenco guitars, and 16:1 for steel string guitars. Those who haven’t yet taken the plunge and installed a set are probably waiting to have various concerns answered. I’ll try to explain how they are constructed, so you can imagine for yourself how well they might work, and also relate some of my own experience with them. I’ve installed over 100 of the pegs, mostly in violins, but also in cellos, ouds, a banjo, and a guitar.

Whether its reappearance stems from the amazing, innovative work of Michael Hedges in the 1980s and ’90s or that of the lesser known but no less interesting guitarists John Doan, Stephen Bennett, Muriel Anderson, James Kline, William Eaton, and many others, this peculiar multistringed instrument — part guitar and part harp — has returned in a big way. (See in-depth coverage of harp guitars in Big Red Book of American Lutherie Volume Three, pp. 178 and 334, originally published in AL#29 and #34.) In Search of the Harp Guitar premiered at the 3rd International Harp Guitar Gathering in Salem, Oregon in September 2005. The film’s maker John Doan also hosted the gathering, perhaps the largest group of harp guitar enthusiasts ever assembled in one place. Many of the film’s “stars,” both musicians and makers, were in the audience. It was a lot of fun to be there and see these folks — many are no strangers to the GAL.

Many of the film’s “stars,” both musicians and makers, were in the audience. It was a lot of fun to be there and see these folks — many are no strangers to the GAL. John Doan has been playing, teaching, recording, researching, and generally advocating for the harp guitar since the early 1980s. He’s the perfect person to put together a DVD that champions the instruments, both past and present, the players, the music, and last (and perhaps most for AL readers), the makers. He has teamed up with his wife Dierdra, Karla Fisher, and Michael King (the latter three behind the camera) to produce a 90 minute DVD plus another several minutes of hilarious outtakes. It’s an ambitious project covering a lot of territory, and it’s held together with the tack of John’s sense of humor and obvious affection for the instruments and his cast of characters as he: ▶ presents a historical overview of the harp guitar, (he’s in lecture mode here, a role he’s obviously comfortable with from his many years of teaching privately and at Willamette University in Salem, OR); ▶ attends the 2nd International Harp Guitar Gathering in Williamsburg, Virginia in November of 2004 interviewing and recording highlights of performances of many including Stephen Bennett, who organized the first and second international gatherings, and other players including Muriel Anderson, Stacy Hobbs, Andy Wahlberg, and many, many others. ▶ visits luthiers in this country and abroad, namely: Fred Carlson, Kerry Char, Mike Doolin, Jeff Elliott and John Sullivan (two for one), Bob and Orville Milburn, Benoît Meulle-Stef in Brussels, Stephen Sedgwick in England, and Michael Sandén, in Sweden; and lastly, ▶ braves LA traffic with water bottle, laptop, and cell phone in hand to visit the extraordinary resource, Gregg Miner’s collection of “Vintage, Exotic, & Just Plain Unusual Musical Instruments” (www.minermusic.com/minermuseum.htm). Guitar makers don’t get too many starring roles, so this is the part I was really looking forward to (plus I know some of these guys pretty well). Generally not comedians (Harry Fleishman excepted), luthiers tend to take themselves fairly seriously. John wrote the script, and the builders conformed to varying degrees. It’s corny; it’s goofy; but it’s fun. John has made it so. The luthiers are all in their native habitats with the exception of Jeff Elliott, who is with John Sullivan at his shop, the location where John Doan’s contemporary harp guitar was made in 1986. Builders viewing the DVD can glean a lot about these shops — about tool and work space organization, workbenches, and most interesting, something of the people and thought processes behind the chisels. Of most interest to other builders might be the Mike Doolin sequence. Mike builds a harp guitar in a minute or two while John Doan “watches,” thanks to the marvels of very fast, edited time-lapse photography. Other high points for me were Michael Sandén’s model-perfect shop in a lovely old building that’s been in use as a woodworking teaching facility since 1880; Kerry Char’s workshop, where every square inch of wall and hanging space appears to be given over to various guitar and harp guitar relics; and Fred Carlson and John Doan in matching hats with ear flaps seriously discussing Fred’s philosophy of building and life. (Is there a difference?) Aside from the visits to shops and to the 2004 Harp Guitar Gathering, the visit to Gregg Miner’s collection stands out. Gregg is a player with a deep knowledge of the history of harp guitars. If you are interested in the arcane, weird, convoluted, idiosyncratic, and bizarre in the service of music making, this collection will definitely scratch that itch. By the way, Gregg will be on hand the 2006 GAL Convention in Tacoma June 21–25 with part of his collection. He’ll also be sharing historical information and participating in a harp guitar concert, as will John Doan and others. And there will be a panel presentation on harp guitars as well. (See p. 5 for the latest convention information.) I enjoyed this DVD immensely and recommend it if for no other reason than to have a good laugh. The soundtrack is not always consistent, the pacing sometimes feels “off,” the humor is sometimes a little forced, and, of course, not everyone important to the harp guitar’s resurgence could be included, for example Steve Klein, Del Langejans, or Alan Perlman, to name a few luthiers. However, it’s certainly worth seeing and perhaps purchasing. John’s own words sum it up best: “Overall, this film documents guitar history in the making presented in the spirit of fun and discovery reaching back centuries, across continents, and beyond six strings.” ◆ [/wcm_restrict]
Posted on August 1, 2022May 23, 2025 by Dale Phillips Questions: Tru-Oil Finishes Questions: Tru-Oil Finishes by Jeff Jewitt Originally published in American Lutherie #90, 2007 ■ Eric Nicholson of Northern Ireland asks: Woodworker magazine published an article on Stewart Adamson’s work regarding Tru-Oil finishes. His method involved a considerable amount of work with Micro-mesh during the process. I tried his method on my own guitars, both classical and steel string, with very satisfying results. Tru-Oil gives an attractive semigloss finish on all woods, but Adamson also goes on to say that for those that like a gloss finish, a gloss tung oil is now available only in the USA. Does anyone know of this gloss tung oil and where it is available in the States, or if it is now available in the UK? Jeff Jewett of Homestead Finishing in Cleveland Ohio responds: Tru-Oil is not pure tung oil. It’s a mixture of linseed oil, mineral spirits, and, according to the manufacturer, “modified oil.” It’s arguable that no tung oil is even used in this stuff. When finish chemists talk about “modified oil” as an ingredient they typically mean either chemical modification or heat modification. Chemically modifying a drying oil involves reacting it with chemicals and heat to form what are known as alkyds, which are used in varnish manufacture. Heat-treated oils basically jump start the drying/curing process. Pure heat-treated oils are used all the time in making finishes, but they rarely show up as “finishes.” The only pure heat-treated linseed oil I know of is Tried and True “Varnish Oil.” Pure heat-treated tung oil is sold in this country under the Sutherland Welles brand (www.sutherlandwelles.com). So I would be tempted to say that Tru-Oil is a mix of linseed oil and some sort of modified linseed or tung oil. Because it has a high oil content, it is not possible to produce a very glossy finish. High oil (also known as long oil) products tend to form microscopic wrinkles at the surface as they cure. There is one way to heat-modify pure tung oil so that it will form a glossy film. This involves careful and controlled heating of the oil to about 450°F. Very few people can cook tung oil properly nowadays, but you can buy it under the Sutherland Welles brand “Original Formula High Lustre.” I don’t know if they will ship overseas. It’s not an easy finish to do, and I’m not sure that it will match the gloss of a French polish, but at least you know it is real tung oil, along with solvent and some driers.
Posted on August 1, 2022March 5, 2024 by Dale Phillips Review: Guitar; An American Life by Tim Brookes Review: Guitar; An American Life by Tim Brookes Reviewed by Ervin Somogyi Originally published in American Lutherie #87, 2006 Guitar: An American Life Tim Brookes ISBN: 0-8021-1796-1 Grove Press, 352 pp., 2005 I found Tim Brookes’ Guitar: An American Life while browsing in a bookstore in Manhattan. I’d never heard of this book, but it’s one of the most enjoyable and informative reads I’ve ever had about the instrument I’ve built my professional life around. It’s written much in the spirit of Richard Halliburton’s marvelous and magical travel books that I read many years ago and that opened up my young mind’s vistas. It was a pleasant surprise to find that this book is, on the initial level, about a guitar building collaboration between the author and Rick Davis, a fellow luthier with whom I have a friendship. A book about a guitar making project written from the client’s point of view: Wow, what a great idea!

Posted on August 11, 2021May 19, 2025 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.
