Hi Steve,

Don't use poly!!  The electrodes get hot, the poly softens, and the 
electrodes fly off...  Guess how I know this ;-))

Go here:

that should all be one line in the web browser.

May I suggest the "Garolites"

Something like part # 8667K117.  Mc-Master-Carr is where I get everything 
like this from.  Highly recommended!

Cheers,

         Terry
