More Pictures
Here are some shots of how Sparky uses the Chladni process in voicing his tops. When I visited his shop early last year, it was impressive to see how he keeps his notes and diagrams on what he learns from the vibrational patterns and how that translates into bracing the guitar.
No way I can explain anything technical about this process but only to say that Sparky makes a very balanced guitar with great tone and great intonation all the way up the neck. 400hz [IMG][/IMG] 237hz [IMG][/IMG] 198hz [IMG][/IMG] 144hz [IMG][/IMG] Thanks for following along. Best, Jayne |

Like you said, don't understand it much but sure is cool they can use this technique to zero in.

If people are interested in learning a bit more about what Sparky is doing, you should check this out:
http://www.blanchardguitars.com/guit...hladni_buy.php Sparky’s teacher on this topic was luthier Mark Blanchard. Mark has a wonderful 68 page presentation that he gave at the 2007 Healdsburg Guitar Festival on this subject. I am not a luthier, but I purchased it about 5 years ago and found it to be both informative and available to the lay person guitarist.

Hi Fred, It’s www.randallkramerguitars.com It is a pretty spartan website but has all the pertinent info on his guitar models. And if you do a web search you’ll find some articles and interviews with him. Best, Jayne |

Jayne,
As you know I have played and loved your Bois Kramer (possibly the finest back and side set I’ve ever seen) and I’m sure this new baby will be absolutely incredible |

For those that want a little more background, one of our Aussie universities has some information too - http://newt.phys.unsw.edu.au/music/g...archladni.html I used to hate physics at school, but if they'd taught this I might have paid more attention! |

This is going to be a wonderful guitar, Jayne! Thanks for letting us follow along! And we get to do "guitar physics!" I stayed away from the whole science building in college. But my husband, the Caltech physics major/NASA engineer is very intrigued by the physics of guitars and that has become one way for us to connect around my love of guitars and music. He says yep-- a well known physics experiment. Can spread sand or talcum powder on any plate to assess the frequencies. Just showed him your pictures and he's intrigued....
I look forward to your updates and following along- beth Last edited by mountainguitar; 03-22-2019 at 08:09 AM. Reason: adding spouse's input : ) |

This is looking like a great guitar. Which is not a surprise. Sparky makes an excellent guitar!

More pictures!
The guitar is coming along nicely and Sparky sent a batch of pictures to me over the weekend. Here is the journey of the back getting both braced and getting that "sawdust mojo treatment". Some back modes before bracing. Frequencies are 273hz, 204hz, 88hz, and 115hz but I can't swear to which is which as the photos may have changed sequence along the way.
