Total Flame Out: Retopping a Harp Guitar

Total Flame Out: Retopping a Harp Guitar

by Harry Fleishman

Originally published in American Lutherie #100, 2009



Falling in love causes people to do crazy things. It made me build a harp guitar using a piece of redwood that was so obviously problematic that I should have run from it. But I fell in love with it for its beauty. I should have been faithful to the wonderful straight-grained wood I’d had such success with. But no; I was blinded by its gorgeous curls. Like a C-street politician, I’m paying the price now.

Replacing the top on a complicated instrument is no picnic, I can tell you. The harp guitars I’ve made have no actual centerline and no points of symmetry. But once I made the decision to go forward with the retopping, I remembered a cool description of how Taylor Guitars does it. Bob Taylor has the good sense not to trash a guitar just because it doesn’t sound good. He also has the good sense not to sell a guitar that isn’t up to his standards. He also has a CNC machine and interchangeable parts for his guitars. Not I.

Routing Neck Dovetails, Part 2

Routing Neck Dovetails, Part 2

by Roy Woltz

Originally published in Guild of American Luthiers Data Sheet #162, 1980



Here is the simplified method of making dovetail neck joints with a router and dovetail bit.

First, figure the depth of the guitar body at the heel. Mine are usually 3 3/8", so I make the dovetail 3" long. It will taper about 1/4" to the inch.

The female jig is designed to be used with a holding mold attached to a table. The mold must be fastened to form a 90° angle to the table top and to bring the heel surface of the body into such a position that the jig can be extended over it. The body is put in the mod with the soundboard facing out, and is held in working position with the wedges and rubber bands.

Dulcimer Gluing Jig

Dulcimer Gluing Jig

by Tony Pizzo

Originally published in Guild of American Luthiers Data Sheet #70, 1978 and Lutherie Tools, 1990



This is a fairly easy-to-make jig for gluing dulcimer sides to bottoms, end blocks, and scrolls. It is adjustable in three planes (length, width, and with minor changes, depth) and adjustments can be made to adapt it for gluing psalteries, scheitholts, or any other type of non-necked chordophone.

The jig consists of a sheet of 1/2" plywood fitted with movable dowels running along a series of parallel channels. Shafts of 1/4" threaded rod running through the dowel centers allow the dowels to be tightened in a prearranged pattern. Angle iron brackets which rest on the top of the dowels can be tightened down to hold the sides down against the bottom during gluing while at the same time ensuring that the sides are held in the pattern already set for them.

Curved Panel Templates

Curved Panel Templates

by Reagan Cole

Originally published in Guild of American Luthiers Data Sheet #80, 1978



Many instrument makers prefer to build guitars, mandolins and the like with pronounced curvature to the back panel(s). The most common method of fabricating a “vaulted” back is to work from a solid plug mold which must be carved and shaped to very exacting standards to produce acceptable results. The plug mold is in fact the best answer when one is building a number of identical instruments. The drafting technique I shall describe is a workable alternative for “one-off” projects or as an aid in visualizing three dimensional forms.

Begin by making a full scale orthographic drawing of the intended form. This will show the back and side views, but it is not directly useful in determining the dimensions of thin wood (or other material) to be used in the construction.

Meet the Maker: Kevin La Due

Meet the Maker: Kevin La Due

by Cyndy Burton

Originally published in American Lutherie #81, 2005 and Big Red Book of American Lutherie Volume Seven, 2015



The fall colors of upstate New York were in full regalia as my sister and I drove towards Binghamton, New York, to meet my niece for lunch. She had just started a new job at nearby Vestal High School, where she’d met a teacher named Kevin La Due, who is teaching high-school kids to make guitars. It sounded like a story asking to be told.


Please tell me about your program.

I teach two sections of lutherie per year, one each semester, which distills down to about sixty class hours each semester, not really enough time to make a guitar. Most students work extra time before and after school and during their free class periods. Although about fifty students apply, we only have room for fifteen seniors at a time because of facility, prep time, and budget limitations.
