Thanks, Ron but that's the first place I looked! I just do not understand how the knob shaft moves the upper pulley and thus the dial string unless the string is somehow also linked to the knob shaft! Also confusing was a post on Antique Radio Forums http://www.antiqueradios.com/forums/view...hp?t=38312 which stated:
"Well I figured this one out, too. Not that intuitive - took some experimenting. The trick is to make sure that the nylon crochet yarn (see Ramirez Philco site for brand) just doesn't go around the pulley on the dial rod, but goes around another turn. Then you get the friction so the dial turns."
Well, there is no pulley on the dial rod. Does he mean that the dial cord goes around the upper pulley TWICE, and that creates friction between the dial knob shaft and the upper pulley?
For those who have replaced the dial cord on a 118, if strung up exactly like Ron's diagram (cord goes up and over the top pulley and NOT around it) is there enough friction between the knob shaft and the upper pulley to operate the mechanism? Maybe my upper pulley is worn!
