I've been cleaning and working on my 10F. I've finally gotten everything freed up, oiled and moving fairly smoothly.
Now I have questions about my lead screw and my cross slide.
First, the lead screw. Here's a pic close up by the headstock:
Probably the same as the day it was cut.
Now, closer to the center:
Would you say that's acceptable wear or should it be replaced? If I don't replace it, is it going to have a negative effect? I would assume it would only make a significant difference in the leadscrew when/if I cut metric as I can't disengage the half nuts? I would think just turning stock the backlash will just be taken up when I start the cut?
Next, the cross slide. No pics, but it has a backlash of 50 on the spindle dial, which I take to mean 50 thou. Is that too much? Seems pretty loose. I can grab the compound slide and "click" the cross slide back and forth. The ACME threads looks pretty good, I'm assuming it's the nut int he carriage?
Thoughts welcome.
