Posted on June 12, 2026June 12, 2026 by Dale Phillips Let’s Catch Up With Graham Caldersmith Let's Catch Up With Graham Caldersmith by Juan Oscar Azaret Originally published in American Lutherie #132, 2017 Hop on a plane in Boston. Fly twenty-seven hours to Sydney, then connect on a prop plane to Port Macquarie on the coast of New South Wales. Rent a car (no, the steering wheel is not on that side, dummy), and drive 60KM southwest. (Stay to the left, the left, the LEFT!) Oops, here comes a traffic circle — drive around clockwise, cars on your right have the right of way, remember to exit left, and stay left. Why is that left wheel always grabbing the shoulder... where the heck is it, anyway? Now out of the city (whew!) and on beautiful Australian farmland — rolling green hills in the mild August winter. Past the logging town of Wauchope and the hamlet of Byabarra. The road narrows to a winding switchback climb up the steep slopes of Bago Bluff, and finally we find ourselves on a high plateau of rich farmland in the town of Comboyne, NSW, population two hundred. Comboyne is the home of luthier Graham Caldersmith and his partner Angela MacPherson (Photo 1). On a recent trip to visit our son in Australia, I took the time to spend a delightful day with Graham and Angela in their enchanting home/workshop/tea house where I learned much about lutherie and acoustics, and enjoyed their wonderful hospitality.

Posted on June 12, 2026June 12, 2026 by Dale Phillips The “Mysteries” of Panormo The “Mysteries” of Panormo by R.M. Mottola Originally published in American Lutherie #132, 2017 One of the classics of lutherie literature is the book, The “Secrets” of Stradivari by violin historian Simone F. Sacconi. This thick book contains much detailed information on the instruments of the Cremonese master violin maker, enough so that, for some readers, what may have once been considered to be true secrets of design and construction are revealed. The title of this article is a takeoff on that of Sacconi’s book. Sacconi spent a lifetime researching the instruments detailed in his tome and so the information imparted there can be considered to be definitive. Having recently completed a single long construction project of a replica instrument by 19th century guitar maker Louis Panormo (Photo 1), I am in nowhere near a position to assume expertise in the “secrets” of Panormo’s guitars. But that project did introduce me to a number of features typical of instruments of that time and, in particular, of the instruments of that maker.

Posted on June 11, 2026June 11, 2026 by Dale Phillips Experiments in Audio Spectroscopy Experiments in Audio Spectroscopy by John C. Moore Originally published in American Lutherie #80, 2004 and Big Red Book of American Lutherie Volume Seven, 2015 R.M. Mottola’s interesting article in American Lutherie #70 (Big Red Book of American Lutherie Volume Six) described the use of audio spectroscopy, with a simple home setup, for the analysis of bass guitars. I had read about a spectrum comparison of a Martin D-28 with a Kaman AA 14-4 in An Introduction to Scientific Guitar Design by Donald Brosnac, and have always been intrigued with the idea of capturing in an objective way the “quality” of the sound of different acoustic guitars. Also, my experience has been that seeing colors of nature is enhanced by having tried to paint them, and tasting beer is enhanced by having brewed some. I felt that analyzing sounds from a guitar would heighten the senses here as well. When I read the Brosnac book, written in 1978, the equipment utilized for the guitar comparison sounded exotic and expensive, and certainly beyond the capability of the casual hobbyist. In Mottola’s article, it was clear that the technology of the PC had brought the potential for such experiments within reach. In fact, I already had hardware that could get me started: a digital camcorder that I could extract wave files from and a Sony Vaio laptop. So I decided to have a go at some audio trials.

Posted on June 11, 2026June 11, 2026 by Dale Phillips Making Patterns for an Access Panel Making Patterns for an Access Panel by Lloyd Marsden Originally published in American Lutherie #80, 2004 and Big Red Book of American Lutherie Volume Seven, 2015 The article by Larry Mills and Chris Jenkins on access panels was a valuable explanation. I was beginning a new series of guitars and decided to try the system on one that will receive electronics. After thinking about Mills and Jenkins’ method for some time, I wanted to alter two aspects. The first was the initial patterns for the door and its opening. Not being the greatest at fitting things by bandsaw and sanding, I wanted to find a way to make the patterns so they would automatically fit together. The second was a picky desire to keep the side material continuous. I wanted the door to be veneered with the side material and be replaced so that the grain would remain continuous.

Posted on June 11, 2026June 11, 2026 by Dale Phillips Building an Adjustable Bridge Building an Adjustable Bridge by Thomas C. DeVeau Originally published in American Lutherie #81, 2005 and Big Red Book of American Lutherie Volume Seven, 2015 In my part-time business of making citterns and one-of-a-kind instruments, I find that the adjustable bridges in most catalogs don’t meet my specifications, so I make my own. Now I control the size, shape, and string spacing, and can use woods that match the woods that I use in my instruments. The following describes how I make the bridge design I came up with. For this bridge I use thumbwheel-and-post sets obtained from Stewart-MacDonald, part #3960, and their fretwire, part #148. Start with a piece of 3/4˝-thick stock. Place the outside strings on the instrument and measure the space between them at the bridge position (Photo 1). Add 2˝ and cut a block to this length. Find the center of this length and extend centerlines around the block. On each side of the centerline, mark half the outside string width to establish the outside string positions. Draw lines 1/4˝ outside these string-position marks to establish the positions of the thumbwheel posts.
