*Video - rod is pulled through a die, and every pass means smaller diameter. Starts with 9 mm rod? [https://www.youtube.com/watch?v=pdoL4epRpP8]
*Copper - pulled through many dies to very fine size - [https://www.youtube.com/watch?v=r-A-X6NlIcw]
*Multiple dies are loaded one at a time, then drawing starts. Are all spools pulling? Likely so, as the thinnest wire pulling would break from tension of larger wire size - [https://www.youtube.com/watch?v=nrgv_wpeZQE].
*Silver pulled by hand, starting with a small roller mill - [https://www.youtube.com/watch?v=e4cZoYCgy_4&t=36s]. 
=OSE Notes=
*Pull from one spool to next from a starting spool. Challenge is the first spool - that is a lot of material.
*If start with 3/8" size, need significant spool to start with.
