How and where are curling rocks made?

Question

Just wondering if they have a hollow core, and how they are shaped and machined.

Answer 1

i saw that program too, go to discovery channels home page then go to How Its Made. then select the curling rock topic and watch it. its really neat.

Answer 2

The program 'How it's made' on the Discovery Channel did an excellent program on this in the middle of January... Your best bet would be to catch a rerun of it...

In the meantime, here is some good information...

Answer 3

Curling rocks are a round block of granite. There is a small hole drilled in the middle in order to attach the handle with a bolt.

They are 44lbs, and shaped with metal tools.
