I have question about 14.2cm that is given as the radius. WCF rule R2. states:
A curling stone is of circular shape, having a circumference no
greater than 91.44 cm. (36 in.)
Plugging 91.44 in the formula r = c / 2π, yields radius of
14.55 not 14.2.
So why was 14.2cm chosen as the radius? There was no explanation
given in the Ogawa presentation.
If I were a betting man, I would guess that it has to do with creating the hitting band. Based upon the 36 in circumference, that gives you a 11.46 in diameter. I would bet that when they make a stone, they start with a 11.5 inch blank, and then file the hitting band into it, and more likely than not, they shave 0.25 inches off, which would be about a 14.2 radius. I bet it is hard to make the stone perfectly round and take off less than the 0.25 inches.
