I’m rebuilding a 1959 10K bought from an estate sale (110V back motor). Gearbox was totally glued up and non-functional. Motor was weirdly wired (see separate thread). Have rewired, rebuilt back gears, gearbox and apron with new felts. Given life complexities, its a slow process. I’ve just ressembled back gears and gearbox.
I have some questions.
1. Have I got it put back together right? (see pics)
2. Why does the ‘banjo’ have two necks?
3. Why do I have two gears on the gearbox input shaft?
(I’m guessing 2,3 may have to do with metric threads?)
4. Is proper meshing of the backgears set by the rotation of the banjo?
5. When gearbox tumblers are engaged, it takes a lot of effort to turn the leadscrew by turning the input gears- with apron disengaged. (My hand is red from abrasion on gear teeth). Its impossible when left tumbler is at ‘A’, unless I turn the lead screw with my right while turning gears with my left, even then, only just. I’ve totally stripped down cleaned and lubricated the gearbox. It this just the way it is? I’m using the recommended spindle oil. Has anyone used a modern low friction oil/additive (molybdenum?).
thanks for any advice
