Where can I find coiled cords to mod a hotshoe?

I'm interested in doing some mods to attach a coiled cord to a Kaiser hotshoe.
Anyone know where I can get some coiled cord? I remember following a link sometime back to a website that had tons of coiled cord with all the different specs such as thickness of the cord and it even had a cross section diagram of the cord. Unfortunately, I didn't bookmark the link and now am lost trying to find the darn thing.

Any help appreciated. Thanks.

Belden makes coiled and other cords for a multitude of purposes. You can find them online.
