There has to be several versions of the dial drive on the 118 (typical Philco!) On my radio the hinged fiber pulley is on TOP. Below it is the dial knob shaft (it has no pulley attached - solid metal - it has some grooves machined into it that apparently mate with the fiber pulley above it), and on the bottom is the double pulley (fixed).
Apparently some 118 et al variants had a pulley attached to the dial knob shaft. That would appear to work better than my configuration, although the dial drive reduction would not be as great.
I think the best fix for my configuration would be to find a small pulley with an outside diameter similar to the fiber upper pulley that would fit on a 1/4" shaft secured by a set screw. Then I would remove the hinged upper pulley like you did and string it up like Ron's diagram. I guess I'll start browsing Granger and similar sites for such a pulley (I do have a small Unimat lathe, but probably NOT the skills!)
