Fiddle Jameson: Acoustics, what sound features make a good sounding violin? Ask three violin makers and get four opinions… Actually thanks to some great work done by Carleen Hutchins, Joseph Curtin and the Oberlin acoustics workshop luthiers we have a fairly good idea of What acoustically represents a “good” sounding violin. The video shows Chladni sound patterns forming as a signal generator excites the plates at ascending frequencies. You can also identify the frequencies where these patterns occur with a spectrum analyzer, looking for peak energy for specific frequencies. We use the frequencies to calculate the plate stiffness and impedance. Calculating the stiffness is better than twisting the plate and hearing a crack when you press too hard… done that a few times, Ouch Impedance determines how much bow pressure a violinist needs on a string to start and maintain a tone. Too much pressure and the instrument is hard to play having limited dynamics. Too little pressure and the tone is mushy having little projection. Like Goldie Locks in the fairy tale we are looking for the acoustics that are just right:-). We take lots of measurements and compare the results over and over and over

Violin Regina: Setting this violin up in the white. I had everything done to put the strings on and then I realized I didn’t have an end pin. So, turn on the lathe and make one

Fiddle Jameson: Graduation, roughing out the inside of the plates. The thickness of the plates will range from 2.2 to 4.5 mm. I use my beam calipers, fashioned after one used by Stradivarius, to score the thickness lines in the plates. Then I use a gauge to remove the lines. When the thickness gets within 1 mm of final I switch to finger planes. If I switch to finger planes too soon my fingers tell me about their sore spots when the day is done. When I’m within .5 mm of my target thickness I switch to smaller finger planes and scrapers. This is the first 5-string model so I don’t have the final plate 3d scans. On my next version of this model I’ll use the CNC machine to speed up the process to within 3mm. That being said, the final finger planing and scraping must be done by hand, because this is when I test the resonate frequencies which determine the instruments ultimate voice

Fiddle Jameson: The purfling corners are all glued in, the arching or the outside curvature of the plates is almost finished all except the finalizing of the edges. The final shaping of the edges will occur after everything else is done on the plates. There’s a fair amount of dinging and danging on the edges during the graduation process, sound holes, bass bar and finally glue up and leaving a little extra wood at this time is a good idea. Now I’m working on the graduation, which is carving the thickness of the plates. The graduation phase is probably the most important aspect of the instruments sound. It determines the resonance of the plates; how they will vibrate when a violinist draws a bow on the strings

Fiddle Jameson: Setting and gluing the purfling. With the grooves cut, I bend the purfling with a hot bending iron, then dry fit all the purfling corners on the top and bottom plates. Once everything is set I glue the purfling into the grooves. The hot hide glue causes the grooves to swell a bit more narrow and the purfling to get just a bit longer than the dry fitting, so there is always some last minute adjustments before the glue cools and sets. Wood, such a dynamic material

Fiddle Jameson: Cutting and trimming the purfling groove. Once the edge margins are smooth and finished, no bumps etc, that edge is used to guide the process of cutting the purfling groove. I set my CNC machine with a 1.4 mm bit 2mm off the table, and positioned the router forward from a guide pin. Once I’ve tested the dimensions on some scrap wood, I put the plate next to the guide pin and give the command for the router to go to 2mm. Once the router is lowered I carefully guide the plate edge around the guide pin. The router is only used for the long curves, once I get into the corners I retract the router and leave that work to be done by hand. The corners are finished off with the traditional, marker, knife, and purfling cleaning tool
