    100+ Year-Old Mandolin Restoration

    This Oscar Schmidt mandolin, built in the late 19th or early 20th century, came to me several months ago in virtually unplayable condition.  Years of string tension had pulled the neck forward to the point where the strings were too high off the fretboard, and a well-intentioned owner coated the original French polish with “modern”…

    Combining Tradition and Modern Technology

    I’ve completed the first significant step in my 2025 mandolin build! Rough construction of a mandolin neck involves 12 distinct steps including cutting and squaring the main shaft, shaping the tenon which will fasten the neck to the body of the instrument at a precise 5 degree angle, building out the head at 14 degrees…

  • 2025 Mandolin build!

    2025 Mandolin build!

    This month, I started building a batch of archtop mandolins to be completed by winter, 2025. They’ll feature Loar-inspired arching and graduations for that punchy tone that cuts through in a jam session (see video clips of my instruments below). I prefer to build 5-6 instruments as a batch, but to customize the design of…

  • Guitar Bracing Experiment:  Final Conclusions!

    Guitar Bracing Experiment: Final Conclusions!

    My experiment with two guitar bracing systems has come to an interesting conclusion. Both guitars have great volume and projection, and a strong bass tone. The Martin-style scalloped X-bracing (1st video: sorry for the cell phone quality audio!) seems to have produced a relatively stronger treble response (more “sparkle” according to one player), while the…

  • A Water Uke

    A Water Uke

    This tenor ukulele is instrument #3 in a series I’ve made from Mninga (Pterocarpus angolensis) reclaimed from old furniture in Tanzania. The customer, a for a water walker in Minnesota. She said she wanted a water theme, so after some conversation we agreed that I would inlay the course of the St. Croix river in…

  • They have a voice!

    They have a voice!

    I’ve been building two guitars with similar design, but different bracing. Once an instrument is structurally complete (but not varnished) I like to string them up to get an initial idea of their tone. First impressions: Despite their different bracing strategies, they’re both VERY loud and they sound remarkably similar. Their fundamental frequencies rose considerably…

  • Sculpting a neck

    Sculpting a neck

    Carving the neck is one of my favorite steps in building an instrument. The many curves and angles each have a function, but when it all comes together, it feels like sculpting a work of art. The neck starts out as three pieces glued together and cut to shape: The heel is rough carved with…

    A Reqinto is Born

    Sent my first requinto out in the world. This is the 3rd instrument I’ve built from Mninga (Pterocarpus angolensus) wood that I salvaged from the top of a coffee table in central Tanzania. Requintos, mainly played in Mexico and Latin America, are tuned 4 steps higher than a standard guitar, and use nylon strings, but…

  • A Sonic Fingerprint

    A Sonic Fingerprint

    The backs are on the two guitars I’m building to compare bracing patterns, and this allows me to measure the main frequencies of each guitar body. The results fit my expectations with the more modern Gore-inspired bracing producing higher pitched main frequencies than the scalloped X-bracing. In fact, the latter was so low (main air…

    More on Guitar bracing

    Last month I described an experiment I’m conducting with 2 different bracing styles on 2 guitars I’m building.  The tops are now attached to the ribs, so I can begin testing the relative strength of their bracing.  This deflection jig measures how much the top moves when a force is applied directly on the bridge…
