[pianotech] Cutting ivory into a circular shape

[Debbie Legg]

It seems that one must dry the circles flat and weighted.  Upon 
evaluation, this morning, of the circle drying by leaning...it curled.  
It would appear that drying an ivory head in this manner provides enough 
support to the grain to prevent curling, while the circle is only 
supported at two points (12 and 6 o'clock) therefore allowing the 
unsupported grain to cause curling.
