  1. Thanks for the explaination of your method, Melvin. A thick back centre brings my imagination to archery : having steady centre, the bow can flex only in the ends. On violin, a stiff back centre shifts bending mainly on the scooping. In any case, I am aware of the fact that this image, like that of the loudspeaker behavior is a bland approximation...
  2. 8 mm back thickness! I'm always interested in borderline solutions and this one is a record, I think, keeping it that way and resisting the temptation to come back to conventional graduations... Now I'm curious to know more about sound. More projection this way? And what about quality?
  3. We have to remember Strad Duport top arching of just 20 mm! The best cello sound, for my taste. The ratio between cello and violin put this quote not as low as 8,5 mm but neither too far from that...
  4. Hi Joe, according to the video, it seems cochineal rosinate disperse itself in oil without mulling... About optical effect, do you know why a rosinate based on colophony appears more monochromatic than one on linseed oil?
  5. Something like this, I can imagine.
  6. Alum solution. The blond one, a solution of colophony and potassium hydroxide in water, I suppose.
