Chaining nunchaku

[RedLynx]

Sorry to be a bother, but I need to put a new chain in a pair of nunchaku I carved. What chain do you recommend and how can I get the chain firmly down in the nunchucks? Should I drill a hole a buy chain with a thread at the ends maybe? If not, what is the *professional* way to do it?

 

Thanks!

but would buy the chain from a martial art store like http://www.awma.com
