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
