use a string to mark out the circumference (near the tip) and then use a ruler to measure it. take that reading and divide by 3.14 (pi). this will give u the diameter of the shaft.

i'm just trying to help the poor kid here since i'm from singapore too. well if u're curious enough, check out poolfanatic.com his nick is HyperSonic.
maybe other singaporean posters here on azb can also verify. help! :p
i dont know him personally but he's on a singaporean pool forum which i frequent. he's not exactly the most popular poster there if u get what i mean.
with that said, i do think he is really 14.
ps. i think most singaporean kids know that song.
