I found out- quite by accident when I went to thread a piece and the dial wasn't turning- that my 9A dial has enough "play" for it's lower gear to be pivoted off the leadscrew, even though both allen head screws are tight. Guess this doesn't surprise me given the screws are on a round shaft, but it hadn't worked it's way "loose" off the leadscrew in the more than a year since I bought and re-built it.
Now I wonder if it doesn't make sense to keep it pivoted out of the way when I'm not threading to avoid wear on both screws. Or, maybe that's what's supposed to be done by design and I never knew it?
