More about the fingerboard

 I spent a the weekend deep diving into the fingerboard geometry, and tried a variety of different things - different radiuses and how they would work for different sets of strings, to figure out what would be the best profile for the specifications:

1040mm string length, fingerboard width 40 - 90mm, strings 26mm apart.

5    5.75    6.5    7.25 string height from fingerboard at 92 cm which should give the notes G, G sharp and even F. When a ruler is placed across the middle two strings, there should be 9 mm distance from the ruler to the outer strings to give good clearance.





In order to get this I dropped the outer two strings half a mm, keeping the distance of 26mm. Making the radius smaller did not help. Instead I flattened the profile out under the outer two strings which will make for a lighter fingerboard that should be possible to be made in one pressing instead of two.
This is what the profile looks like. I haven't finished the surface modelling yet.

It's a very long fingerboard, with just 12cm to the bridge. It would be easy to shorten though, and this could be done from either end if one wanted to use this model for other instruments.

When I set the neck I will adjust it about 2.8 degrees to make the line over the D and A strings flatter. This should make it slightly more comfortable for a French bow. For German bow, I would have kept the neck foot at 90 degrees.

  1. Thank you for this about the fingerboard Elinore! I will get back to you concerning this to discuss some aspects, but as I will have to leave for a rehearsal now, it will be late night or maybe even tomorrow..
