Okay, I was just at the lathe and tried to again move the scale for the handwheels on both the compound and tailstock. Nothing budged. I removed the compound handwheel/dial and they appear to be solid. I wouldn't say one piece but possible a press fit? I don't see how the dial could move independent of the handwheel. I WANT to be wrong but.... ugh. Here's the handwheel/dial I removed from the compound.
