John E repechage I found a fellow with a blog post about the assembly and adjustment of the Simplex Tour de France derailleur, as I knew that there had to be some way to make it so that the maximum distance could be set. It turns out it's as simple as loosening the outer nut then re-positioning the inner screw to tension the pulley. So now I don't have to worry about it hitting my spokes if the cable were to loosen up, but it does still barely get up onto the large cog despite adding two links to the chain as well. Perhaps the cog size is a bit much to ask for without really testing the limits, as I kept it about 1/8" away from the spokes.
Of course I also put on the little NOS cable clip that I am thankful for having pointed out to me!
