Violin bow hair
What is Mongolian hair look like under a strong microscope? I am not planning to buy one. I am told that they have no barbs as some think.
Um, I wasn't aware any type of horse hair has barbs...!

Thank you Carlos
Very good, Carlos. I have seen this information previously, but this link is a very concise and most valuable contribution for this violinist.com forum.
I have a question. The data you give is related to the hair flexibility and from that to calculate the number of hairs to give the string the best sound but in the calculation nothing is mentioned regarding the stick flexibility/stiffness apart from a "normally tightened bow". Does that mean that normally tightened bows would have the same properties in the transmission of the force to the hair and to the string? That would be counter to what seems to be the regular practice of looking for almost mystical sticks and pay a lot less attention to the hair...
I have often wondered about how much of bow evaluation is really about the hair. And I have had a very hard time getting good and consistent rehairs.
That is some pretty deep bow physics you have experimented with and explained for us Andrew. Thank you even though I did not understand very much of it, especially the numbers part.
