Posted on July 7, 2024May 9, 2025 by Dale Phillips It Worked for Me: Low Cost Emergency Lathe It Worked for Me: Low Cost Emergency Lathe by Gerhart Schmeltekopf Originally published in American Lutherie #29, 1992 and Big Red Book of American Lutherie Volume Three, 2004 Most luthiers probably don’t have wood lathes, so I submit this low-cost, emergency lathe setup for the times you might want to make a music stand, washtub bass, or baseball bat for the local luthiers’ picnic. I bought commercial turnings to make a student harpsichord stand. They were “sanded and ready to finish,” so I knew that they would need to be sanded before finishing. They are too long for my lathe, so I rigged this temporary reciprocating or “pole” lathe to spin them and sand them.

Posted on June 30, 2024May 12, 2025 by Dale Phillips The Great White Sitka The Great White Sitka by Jeffrey R. Elliott Originally published in American Lutherie #32, 1992 and Big Red Book of American Lutherie Volume Three, 2004 In February 1992 friend and fellow luthier John Sullivan and I drove from Portland, Oregon to Elma, Washington to pay a hands-on visit to Steve McMinn’s Pacific Rim Tonewoods, Inc. (The business has since relocated in Bellingham, Washington.) We went for the experience. Steve suggested we bring some rugged clothing and a camera. We discovered why when we arrived to the incredible sight of a gigantic Sitka log 26' long by 11' across at the larger end. A great white whale came to mind. The photos tell the story. For the next couple days, my body reminded me I’d had a real workout. But it felt good because it reminded me of what a great time we had and how fortunate we were to have a hand in turning this huge spruce log into top wood. Steve’s whole operation is very well thought out, very organized, and a pleasant place to work. He’s obviously committed to producing high quality instrument woods and nothing is wasted. This experience also gave me an appreciation for how much work goes into producing one top and why “ideal” tops are so rare. ◆ Become A Member to Continue Reading This Article This article is part of the Articles Online featured on our website for Guild members.

Posted on June 30, 2024May 14, 2025 by Dale Phillips Mechanical Compliance for Soundboard Optimization Mechanical Compliance for Soundboard Optimization by David Hurd from his 2006 GAL Convention workshop Originally published in American Lutherie #90, 2007 People say, “You’ve got to make fifty or a hundred guitars before you get it right.” That makes me crazy. I feel that if you can do the carpentry of putting an instrument together and have idea of what it should look like, you can get 80% or 90% of the way there in terms of top optimization with a mechanical compliance approach. I build many sizes of guitars and ukuleles using different top woods. I have developed an easy method of testing the compliance of a top, that is, how far it flexes under a given force, with a simple fixture. Being able to measure and compare the compliance values has proved to be a very useful thing in optimizing these soundboards for the best sound and stability when I graduate the edges of the tops and carve the braces. After building and measuring many instruments, I have developed a mathematical model that does a very good job of estimating what the target compliance measurements should be for a given instrument size and string tension. I have integrated the model into a spreadsheet which you can use by plugging in just a few simple measurements.

Posted on June 30, 2024May 14, 2025 by Dale Phillips Construction of the Colombian Tiple Construction of the Colombian Tiple by Anamaria Paredes Garcia and R.M. Mottola Originally published in American Lutherie #90, 2007, Big Red Book of American Lutherie Volume Three, 2004 American Lutherie #82 featured an article and plan for the Colombian tiple by Bogotá luthier Alberto Paredes. This is a companion article to that one, featuring a detailed description of how the tiple is constructed in Sr. Paredes’ shop. The design of the tiple is heavily influenced by that of the classical guitar, but as it was not directly descended from the classical, this instrument has unique characteristics. With its multiple courses of steel strings, the construction of the tiple has to be able to withstand much higher static string tension than a classical guitar. The top is cut from bookmatched spruce, nominally 3MM thick. The two halves are generally cut out on the bandsaw at the same time, as shown in Photo 1. The center seam edges are jointed, first on the jointer (Photo 2). Following machine jointing the top halves are finished up on the shooting board using a hand plane. Note that the halves are simply pressed by hand to hold them down on the board during shooting (Photo 3). Glue is applied to the center seam surfaces (Photo 4) which are then clamped using simple cauls to a flat, waxed gluing board (Photo 5). Once the glue is dry the squeeze-out is stripped off the back side of the top.

Posted on June 30, 2024May 14, 2025 by Dale Phillips Grading on the Curves Grading on the Curves: Fitting Bars and Bridges on Archtop Guitars by Steve Andersen from his 2006 GAL Convention workshop Originally published in American Lutherie #91, 2007 The first thing I’ll show you today is how I fit tone bars to the top. Then I’ll talk about fitting the base of a bridge to a top, first with this router jig that indexes off the top and gets me really close to the final shape, then moving on to the final fitting. I brought some extra materials if anyone wants to try hand-fitting an ebony bridge or a tone bar. I use the term tone bar, because I think of braces as being structural. If you built a flattop guitar without braces, it would just fold up. An archtop could be built without braces and it would hold up fine. The archtop’s bars are not so much for structure, so I call them tone bars. One thing that helps me in the fitting process is that my arching is very consistent from guitar to guitar. The arching templates for my guitars started out based on a D’Angelico New Yorker, and have evolved over the years to what I’m using today. So while I have several body sizes, they have similarities based on what I’ve found works well for my sound.
