After a long hiatus on this, i have been putting some work into it lately. Finally got the chuck scrolling after a bunch of PB Blaster and some tapping with a urethane headed hammer. Still struggling to get the chuck broken free from the spindle. I have tried all type of methods in securing the spindle without damaging the gears, but to no avail. Time and patience i guess. I would prefer to free it before removing the spindle and replacing the felt and oil springs. Unfortunately i am in need of a new phone, but hope to follow with some pictures soon.
