Elliott Originally published in American Lutherie #91, 2007 François Leonard of Port-Louis, France, asks: I’m guitar maker in France and I’ve been following and reading articles in American Lutherie since many years. I had recently an order for a 10-string guitar and I’m asking myself how much I need to reinforce the design of the bracing. My bracing is not so different from the one Jeffrey Elliott uses and talks about in his AL#56 article “Shaping the Sound.” Jeffrey R. Elliott of Portland, Oregon, responds: My experience is more extensive with 8-string guitars, but I believe the same principles apply. I suggest the following: Select top wood that is more stiff than you would choose for a 6-string, one with all the characteristics you usually look for, but also with a somewhat extended tap-tone range toward the lower pitches.

Posted on June 6, 2024January 16, 2025 by Dale Phillips Questions: Guitar Rib Depth Questions: Guitar Rib Depth by R.M. Mottola Originally published in American Lutherie #85, 2006 Mark Korsten of Hastings-on-Hudson, NY asks: The article concerning how the rib depth of guitars should be adjusted when plates are domed was clearly written and illustrated (AL#84). I truly appreciate the insights offered by author R.M. Mottola. Being a neophyte luthier, however, I have what is probably a naive question. How does changing the depth of the guitar’s ribs modify the manner in which the bindings are fitted to the binding ledge? It’s a fairly easy operation to bend the binding when the plates are flat. However, when the depth of the ribs are varied, doesn’t that introduce another plane to the geometry? Do you simply use more flexible, thinner bindings or stronger binding tape to keep things tightly apposed in the ledge? R.M. Mottola responds: Although the doming of the plates means that the side depth of the ribs must be varied so the ribs and plates can be glued, this type of construction has little effect on binding. The ledges can be routed using a router resting on the plate or inverted in a router table. In either case the doming is so slight that the routing can be done just as if the plates were flat. And although the bindings must be bent vertically to accommodate the varying rib depth, the amount is so small as to be inconsequential. ◆
Posted on June 6, 2024January 17, 2025 by Dale Phillips Letter: Side Soundhole Guitar Letter: Side Soundhole Guitar by Marc Connelly Originally published in American Lutherie #93, 2008 Dear GAL Family, Thank you Cyndy Burton for the exploration of side-ported instruments. It was a terrific affirmation for this most interesting fenestration option. Like Mr. Montelone, at some point I laid my head on the side of my old Martin, strummed, and wondered how to get more of that big wood and bronze sound into my face. I started experimenting with a “side hole” variant, and it changed the way I think about what I am doing — not because it was “better,” but because it was clearly different in a thought-provoking way. In fact, this exercise has finally purged the word “better” from my lutherie vocabulary, and that’s a good thing. My side-hole instruments (which I call “Atlas”) are from the same plantilla as my front-hole models, so I can make some general comparisons. At first, the Atlas models seemed a bit too percussive and weighted toward the bass. So I made some small modifications in the way I tune the box and tamed the bass. The percussive nature of these guitars is simply a component of getting a more direct blast of wavy air into the player’s face. I have come to like this. Several Atlas owners have agreed it has an appeal and have readily adapted to it. But a truly freakazoid experience is to stick your left ear in the hole and play! There isn’t a prewar D-45 on the planet that sounds like that! Until I read Montelone’s article, I never even considered the possibility of weakening the side. What was I (not) thinking! None have folded up, but future Atlas models will have some consideration for this possibility. Fusion jazz player Don Mock owns an Atlas and loves it. Don enjoys having people ask “What’s that?!” Of the folks who play my guitars with some interest in commissioning one, the Atlas is always the first off the rack. But guitar players are an amazingly conservative lot, I find. Selling a side-hole guitar is like selling a blonde guitar. You are either open to them or you are not. It is personally rewarding to watch the tug of war between the conventional and the unconventional. ◆ Photo by Marc Connelly.

Mottola Originally published in American Lutherie #97, 2009 Greg Pacetti of Fairbanks, Alaska asks: I’m in pursuit of some kind of jig for oval rosettes. The Questions column editor responds: Probably the single best source of info on cutting oval rosette channels appeared in the American Lutherie article “Making Oval Mandolin Rosettes” by Jonathon Peterson, et al. (AL#41 p. 34, BRBAL4 p. 140). In it, seven builders describe their methods. ◆
Posted on June 6, 2024January 16, 2025 by Dale Phillips Questions: Info on D’Angelico Questions: Info on D'Angelico by Linda Manzer and John Monteleone Originally published in American Lutherie #96, 2008 John Langdon from the Internet asks: I’m quite obsessed with D’Angelico and D’Aquisto guitars, and there are not many sources of info besides the GAL and the wonderful book Paul Schmidt wrote. Would you happen to know the maker of those elusive violin maker’s planes James D’Aquisto had? In one of the GAL books he said they were made by a company in Boston. Do you know if John D’Angelico used a jointer or a hand plane to join his plates? I’m also trying to find out more about the nitrocellulose finish D’Aquisto used. I’m curious if his finishes were alcohol based or not. Do you know if he had any preference for any specific brand of finish or colors? Linda Manzer from Toronto, Canada responds: I used the hand planes in question when I worked in D’Aquisto’s shop in 1983. I made copies of those planes for myself and sold a limited number of them a few years back as well. I plan to resume making them in the near future. They are fantastic.
