Ha got ya!
Seriously it seems like any time I spend any length of time at the lathe, like tonight, I end up with a seriously hurting neck & upper back. Now I actually think my lathe is mounted too high but it seems to me that this problem would be caused by it being mounted too low.
So what's a good rule of thumb for comfortable working height of a lathe? I remember Bill sizing me up for turning on his poolewood when I took my lesson. I think he said the center line of the headstock should be about elbow high - am I remembering that right?
