I'm not sure of the way to string it on the radio, but if you look up "vintage radio dial cord" on eBay you will find quite a selection. I think one of the thicker cords would serve your purpose, either 0.040" diameter, or 0.050" diameter. You can buy it in 12 foot lengths quite reasonably. As for the stringing diagram for your particular model, unless someone on here has the exact information, you might search through the diagrams you can find in the PDF file you can download from this site, http://www.nucow.com/alldial.htm ,and look through it until you find one that matches the shaft and pulley layout of your model.
