Post-crown Preparations:
Understanding The Ferrule Effect (3)

A ferrule is a ring of metal that encircles the end of a wooden pole, to stop it splitting.



This ferrule has been put on the end of a snooker cue.


What would happen if you hammered a nail into the end of the cue? Would the wood split?




If there was no ferrule, would the wood split if a nail was hammered into it?
