  Subject: [pianotech] crown and radius

   

  Greetings,

  As my math skills are weak - I am looking for a formula or table for determining the crown that is built into a radius cut rib based on radius and rib length.

  Also, if the apex of the radius is not centered on the rib length is there a way to calculate the crown?

  Any help would be appreciated.

  Gene
