Posted on July 7, 2024May 19, 2025 by Dale Phillips Novice Notes Novice Notes by Donald Curry Originally published in Guild of American Luthiers Quarterly, 5, #3, 1977 Editor’s Note: This column marks the last of the regular “Novice Notes” series which has run in the GALQ for a full year now. Mr. Curry assures us that he will continue to follow the Guild’s activities with interest, and I would like to take this opportunity to thank him most warmly for the excellent and reliable manner in which he has presented this informative series. This final step in the making of an instrument is the finish, which includes preparation of the wood, applying the finishing material, and the final polishing. This subject probably has more diversity than any other in lutherie. Every luthier and every book on the subject differ as to how to produce a proper finish. Many different methods have proved equally successful and for this reason I will not go through a specific procedure but comment on some important aspects often overlooked.

Posted on July 7, 2024May 14, 2025 by Dale Phillips Waterborne Solutions Waterborne Solutions by Mike Doolin and John Greven from their 2001 GAL Convention demonstration Originally published in American Lutherie #73, 2003 Doolin: Waterborne finishes and methods of working with them are constantly evolving. New products come out every year and old formulas are continually being updated. This workshop is like a snapshot of what John and I were doing at the time, and our techniques have continued to evolve. We trade techniques back and forth and share our results with new products as they become available. We never seem to be using exactly the same products or techniques; this just goes to show that there is no perfect finish product or technique yet. However, John and I agree that the products which have become available in the last few years are finally up to the task of producing a finish worthy of a fine handmade guitar. Before we get into the nitty-gritty, I want to talk about what waterborne finish is. First, think of lacquer and shellac. Both lacquer and shellac are resins dissolved in solvent. Spray it on, the solvents evaporate out, and that’s it. There’s no structural cross-linking reaction going on. Anytime after the finish is dry, you can use lacquer thinner to wipe the lacquer off the guitar. The same is true for pure shellac, which is always soluble in alcohol. That’s useful for a finish which will be rubbed out, particularly if you’re going to be touching up at a later time. You can melt that coat in. Otherwise, if the subsequent coat has to stick by a mechanical bond, you get a witness line if you sand through the top coat. One of the advantages of the new waterborne finishes is that they seem to do that — to burn into their previous coats. That’s one of the things we’re looking for.

Posted on July 7, 2024May 14, 2025 by Dale Phillips The Case For KTM The Case For KTM by Michael Turko Originally published in American Lutherie #72, 2002 For ten years now I have been building custom guitars, and I have been using KTM waterborne lacquer as my only finish coat for most of that time. I believe it is an excellent choice for the small custom builder for a variety of reasons. ▶ There is no offensive odor or noxious fumes to create problems in residential neighborhoods. ▶ It may be applied by hand without sprayers or other specialized equipment. ▶ It dries extremely fast, and may be buffed to a high gloss within hours (or less) instead of days. ▶ It builds much faster than solvent-based lacquers, and many coats can be applied on the same day. ▶ No special pore or grain fillers are required. ▶ It dries absolutely clear without adding any tint or shade of its own (although tinting maybe added if desired).

Posted on July 5, 2024May 15, 2025 by Dale Phillips The Case for Using Natural Dyes The Case for Using Natural Dyes by Nicholas Von Robison Originally published in Guild of American Luthiers Quarterly Volume 11, #1, 1983 and Big Red Book of American Lutherie, Volume One, 2000 Luthiers do not need to color their raw materials as much as other woodworkers. We use fine woods that can stand on their own merit without any help from the dye pot. But now and then we do find a need for dyes: for example, for rosettes, bindings, taking grey streaks from ebony, enhancing the color cast of wood, and tinting finishes. In 1856 young William Henry Perkin was trying to synthesize quinine but instead wound up with a black tarry mess. This was mauveine, the first of the coal-tar derived dyes. By 1900 the aniline dyes (coal-tar derived) had virtually replaced all other dye materials. Up to this point, dyeing was done with naturally occurring materials and was more of an art than a science. With aniline dyes results were predictable, repeatable, stable, nonfading, and a heck of a lot simpler. There was bound to be a reaction, of course. The art of natural dyeing is returning to the amateur weavers and textile artists; I doubt if woodworkers will be far behind.

Posted on July 1, 2024May 22, 2025 by Dale Phillips Questions: Spraying Lacquer in Garage Questions: Spraying Lacquer in Garage by Jeff Jewitt Originally published in American Lutherie #101, 2010 MR in Portland, Oregon asks: Anyone have suggestions for spraying lacquer in a small one-car garage? Do you really need an explosion-proof fan? I do have an unfinished bathroom in my basement, and it has a cheap exhaust fan. Jeff Jewitt from Homestead Finishing Products in Cleveland, Ohio responds: I definitely suggest a garage over a basement for spraying solvent lacquer. A basement is very hard to exhaust properly and most basements don’t have a large enough window for the fan necessary for flammable products. In addition, the residual odor from lacquer will be more noticeable in a basement than a garage.
